The tables on this page list all the attributes that you can set for local and remote queue managers. For each attribute, there is a brief description of when you might need to configure the attribute. Where relevant, the tables also give the equivalent MQSC parameter for the ALTER QMGR and DISPLAY QMGR commands. For more information about MQSC commands, see Script (MQSC) Commands in the IBM® onlineWebSphere® MQ information center.
Those attributes for a queue manager that are changed through MQSC using the ALTER QMGR commands are the ones that are shown for both local and remote queue managers. Note, that the WebSphere MQ Explorer does not show all the properties for remote queue managers.
Those attributes that are defined in the qm.ini file (for UNIX systems) or in the Registry (for Windows), are the ones that are shown only for local queue managers. For example, the specification for the Recovery Logs and the XA apply to the qm.ini file, and so, is shown only for the local queue manager.
For lists of all the attributes that you can set for both local and remote queue managers in the queue manager's properties dialog see the following tables:

Some of these properties pages are available only on distributed queue managers, such as those running on Windows, AIX®, or Linux (x86 and x86-64 platforms). Properties pages that are not available on z/OS® queue managers are indicated.
The attributes that are marked with an asterisk (*) update configuration files so you can view and edit them when the queue manager is stopped. If you edit the marked attributes when the queue manager is running, you must stop and restart the queue manager so that the changes take effect. You can edit the unmarked attributes only when the queue manager is running. For more information about the configuration attributes, see Changing queue manager configuration information in the IBM online WebSphere MQ information center.
The following tables list the system parameters that you can set for remote z/OS queue managers. These attributes are not displayed in the Queue Manager properties dialog. They are included here because they are still attributes of the queue manager. For more information, seeConfiguring z/OS queue manager system parameters.

| Max message length | Type the maximum length of messages, from 32 KB to 100 MB, that is allowed on queues on the queue manager. The default value is 4 MB (4 194 304 bytes). If you reduce the maximum message length for the queue manager, you must also reduce the maximum length of the SYTEM.DEFAULT.LOCAL.QUEUE definition, and all other queues that are connected to the queue manager. This ensures that the queue manager's limit is not less than the limit of any of the queue manager's queues. If you do not do this, and applications inquire only the value of the queue's Max message length attribute, the applications might not work properly. | MAXMSGL |
| Max properties length | This value controls the size in bytes of the property data that can flow with messages in a V7 queue manager. If the size of the properties exceeds the maximum properties length then the message is rejected. | MAXPROPL |
| Max priority | Read-only. This is the maximum priority of the queue manager, which is 9. | MAXPRTY |

| *Error log size | Specify the size of the queue manager error log at which the log is copied to the backup. The value must be 1048576 - 2147483648 bytes. The default value is 262144 bytes (256 KB). | (Not applicable.) |
| *Excluded messages | Your WebSphere MQ system might produce a large number of information messages if the system is heavily used. You can therefore exclude certain messages if required. Type the message ID of each message that is not to be written to the queue manager error log. Enter a comma-separated list of message IDs from the following list:
| (Not applicable.) |
| *Suppressed messages | Your WebSphere MQ system might produce a large number of information messages if the system is heavily used. You can prevent selected messages being sent to the console or to the hardcopy log if required. Type the message ID of each message that will be written to the queue manager error log only once in a specified time interval. The time interval is specified in theSuppressed Messages Interval attribute. Enter a comma-separated list of message IDs from the following list:
If the same message ID is specified in both the Excluded Messages and theSuppressed Messages attributes, the message is excluded.
| (Not applicable.) |
| *Suppressed messages interval | Type the time interval, in seconds, in which messages that are specified in theSuppressed Messages attribute will be written to the queue manager error log only once. The value must be 1 - 86400 seconds. The default value is 30 seconds. | (Not applicable.) |
| Custom | The Custom parameter is reserved for the configuration of new features before separate attributes have been introduced. The possible values are a list of zero or more attributes-value pairs, in MQSC-style syntax, separated by at least 1 space.
The attribute names and values are case-sensitive, and must be specified in uppercase. The values can contain spaces and parentheses, but must not contain single quotation marks. Examples of valid syntax are:
The queue manager parses the value, but if the string cannot be parsed according to these rules, or if it contains attributes or values that are not recognized, the queue manager ignores the errors.
| CUSTOM |
| Opening shared queues | (z/OS only) When a queue manager makes an MQOPEN call for a shared queue and the queue manager that is specified in the ObjectQmgrName parameter of the MQOPEN call is in the same queue-sharing group as the processing queue manager, the Opening shared queues attribute specifies whether theObjectQmgrName is used or whether the processing queue manager opens the shared queue directly. Use the queue manager specified inObjectQmgrName means that the ObjectQmgrName is used, and the appropriate transmission queue is opened; Use the local queue managermeans that the processing queue manager opens the shared queue directly, which can reduce the traffic in your queue manager network. | SQQMNAME |
| Intra-group queuing | (z/OS only) Specify whether intra-group queuing is used. To use the shared transmission queue (SYSTEM.QSG.TRANSMIT.QUEUE) when queue managers within a queue-sharing group exchange messages, click Enabled; to use non-shared transmission queues and channels when queue managers within a queue-sharing group exchanged messages, click Disabled. If you disable intra-group queuing, the same mechanism for message transfer is used as when the queue managers are not part of a queue-sharing group. | IGQ |
| IGQ user ID | (z/OS only) Specify a user identifier to be used by the IGQ agent to establish authority to put messages to a destination queue. The queue manager must be a member of a queue-sharing group to use this attribute. To specify that the user ID of the receiving queue manager within the queue-sharing group is to be used as the IGQ user ID, leave the field blank. | IGQUSER |
| IGQ authority check type | (z/OS only) Specify the type of authority checking and, therefore, the user identifiers, to be used by the IGQ agent. This establishes the authority to put messages to the destination queue. The queue manager must be a member of a queue-sharing group to use this attribute. To specify that the default user ID is used to establish authority, click Default; to specify that the IGQ user ID and the ALT user ID is used to establish authority, click Alternate or IGQ; to specify that only the IGQ user ID is used to establish authority, click Only IGQ; to specify that the user ID from the UserIdentifier field in the message descriptor, of a message on the SYSTEM.QSG.TRANSMIT.QUEUE queue, is used to establish authority, click Context. | IGQAUT |
| Expiry interval | (z/OS only) Type the approximate value in seconds that specifies how often queues are scanned to discard expired messages. the value must be 1 - 99999999. The minimum scan interval is 5 seconds, even if you specify a lower value 1 - 4. Specify an interval of 0 to ensure that the queues are not scanned; this is the default value. | EXPRYINT |
| Security profile case | (z/OS only) Specify whether the queue manager supports security profile names in mixed case or in uppercase only. Select Mixed to specify that security names can be in uppercase or in mixed case. Select Upper to specify that security profile names must be in uppercase. This is the default value. | SCYCASE |
Exits page (not z/OS)
The following table lists the attributes that you can set on the Exits page of the Queue Manager properties dialog. To configure the queue manager to run user exits, edit the attributes on the Exits page. The attributes on the Exits page relate to stanzas in the configuration files.
| Attribute | Meaning | Stanza key |
|---|---|---|
| *Exit default path | If the queue manager is 32 bit, type the path to the location in which exits for this queue manager are stored by default. | ExitsDefaultPath |
| *Exit default path (64 bit) | If the queue manager is 64 bit, type the path to the location in which exits for this queue manager are stored by default. | ExitsDefaultPath64 |
| *Local API Exits | Add details of the local API exits that you want to use with this queue manager. | ApiExitLocal |
| *Name | Specifies the descriptive name of the API exit that is passed to the API exit in the ExitInfoName field of the MQAXP structure. This name must be unique and is limited to a length of 48 characters, and must contain only those characters that are valid for the name of WebSphere MQ objects, such as queue names. | Name |
| *Type | Specifies the type of exit: queue manager, or override. | (Not a separate stanza key.) |
| *Sequence | This attribute is an unsigned numeric value that defines the sequence in which this API exit is called in comparison with other API exits. An API exit with a low sequence number is called before another API exit with a higher sequence number. The order in which different API exits with the same sequence number are called is undefined. It is perfectly valid for there to be gaps in the sequence numbers of the API exits defined for a queue manager. | Sequence |
| *Module | Specifies the module that contains the code for the API exit. If this field contains the full path name of the module it is used as is. If this field contains just the module name, the module is located using the same method as channel exits; that is, using the value in the Exit default path field on the Exits page of the queue manager properties dialog. | Module |
| *Function | Specifies the name of the function entry-point into the module that contains the code for the API exit. This entry-point is the MQ_INIT_EXIT function. The length of this field is limited to MQ_EXIT_NAME_LENGTH. | Function |
| *Data | If this attribute is specified, leading and trailing blanks are removed, the remaining string is truncated to 32 characters, and the result is passed to the exit in the ExitData field of the MQAXP structure. If this attribute is not specified, the default value of 32 blanks is passed to the exit in the ExitData field of the MQAXP structure. | Data |
Cluster page
The following table lists the attributes that you can set on the Cluster page of the Queue Manager properties dialog. To configure the cluster attributes of the queue manager, edit the attributes on the Cluster page.
| Attribute | Meaning | MQSC parameter |
|---|---|---|
| Cluster membership | Read-only. This table lists the names of the clusters to which the queue manager belongs. | (Not applicable.) |
| Cluster workload exit | The exit is called when a message is put on a cluster queue. Type the name of the cluster workload exit:
| CLWLEXIT |
| Cluster workload data | Type the data to be passed to the cluster workload exit when the exit is called. The maximum length of the data is 32 characters. | CLWLDATA |
| Cluster workload length | Type the maximum number of bytes of message data that is passed to the cluster workload exit:
| CLWLLEN |
| Max outbound cluster channels | Type the maximum number of outbound cluster channels. For more information, see Queue manager clusters in the IBM online WebSphere MQ information center. | CLWLMRUC |
| Cluster workload mode | The cluster workload exit, CLWL, allows you to specify which cluster queue in the cluster is to be opened in response to an MQI call (for example MQOPEN or MQPUT). The default value is SAFE, which means that the CLWL exit is run in a separate process to the queue manager so that if there is a problem, the integrity of the queue manager is preserved. However, running the CLWL exit as a separate process can have a detrimental effect on performance. To improve performance by running the CLWL exit in the same process as the queue manager, click FAST. Use FAST mode only if you are certain that there are no problems with your CLWL exit because if there is a problem in FAST mode, the queue manager fails and the queue manager's integrity is at risk. The value set for the queue manager will override the value set for the machine-wide configuration. | CLWLMode |
| CLWL use queue | This attribute specifies whether the queue manager can choose from remote instances of cluster queues as well as local instances. If the queue manager receives a message by way of a cluster channel, the message is put on a local instance of the cluster queue; if the queue manager receives a message locally or by way of a non-cluster channel, and the value of this attribute is Any, the message is put on either local or remote instances of the cluster queue. To enable the queue manager to use remote instances of cluster queues, click Any; to prevent the queue manager using remote instances of cluster queues, click Local. For more information, see Queue manager clusters in the IBM online WebSphere MQ information center. | CLWLUSEQ |
| Default cluster transmission queue | The default transmission queue type that is used by clustering to transfer messages to other queue managers in the cluster. Messages are transferred by cluster-sender channels.
The default value of this attribute is SCTQ. The queue manager uses a single transmission queue to transfer all cluster messages. The transmission queue is SYSTEM.CLUSTER.TRANSMIT.QUEUE.
To send messages to each queue manager, in each cluster, using a different transmission queue, set the value ofDefault cluster transmission queue to Queue for each channel. The queue manager automatically creates a transmission queue if it needs one to send a message to another queue manager in a cluster. The queue is permanent-dynamic. It is created from the model queue SYSTEM.CLUSTER.TRANSMIT.MODEL.QUEUE. The name of each transmission queue is SYSTEM.CLUSTER.TRANSMIT.ChannelName. ChannelName is the name of the cluster-sender channel that transfers messages from the queue.
| DEFCLXQ |
Repository page
The following table lists the attributes that you can set on the Repository page of the Queue Manager properties dialog. To specify that the queue manager hosts the repository for one or more clusters, edit the attributes on the Repository page.
| Attribute | Meaning | MQSC parameter |
|---|---|---|
| Not a cluster full repository | To specify that the queue manager is not a full repository for a cluster, select this option. | (Not applicable.) |
| Full repository for a cluster | To make this queue manager a full repository for just one cluster, select this option, then type the name of the cluster. | REPOS |
| Full repository for a list of clusters | To make this queue manager a full repository for more than one cluster, select this option, then type the name of the cluster. | REPOSNL |
Communication page
The following table lists the attributes that you can set on the Communication page of the Queue Manager properties dialog. To configure how the queue manager sends and receives messages, edit the attributes on the Communication page.
| Attribute | Meaning | MQSC parameter |
|---|---|---|
| Default transmission queue | Type the name of the default transmission queue on which messages that are destined for a remote queue manager are put if there is no other suitable transmission queue defined. The queue named must be a local transmission queue, but not the cluster transmission queue. | DEFXMITQ |
| Channel auto definition | To enable receiver- and server-connection channels to be defined automatically, click Enabled; to prevent receiver- and server-connection channels being defined automatically, click Disabled. Cluster-sender channels can always be defined automatically, regardless of the setting of this attribute. | CHAD |
| Channel auto definition exit | The exit is called when an inbound request for an undefined receiver, server-connection, or cluster-sender channel is received. The exit is also called when starting a cluster-receiver channel. Type the name of the channel auto-definition exit:
| CHADEXIT |
| Channel authentication | To exercise more precise control over the access granted to connecting systems at a channel level, you can use channel authentication records. WebSphere MQ version 7.1, and later, queue managers are created using channel authentication by default. If you migrate a queue manager to WebSphere MQ Version 7.1 from an earlier release, channel authentication is not enabled. To enable channel authentication, use the command ALTER QMGR CHLAUTH(ENABLED) | CHLAUTH |
| IP address version | To specify that the queue manager uses the IPv6 protocol, click IPV6; to specify that the queue manager uses the IPv4 protocol, click IPV4. | IPADDRV |
| Activity recording | If a queue manager application performs some work on behalf of a message in which activity reports were requested, the queue manager can generate an activity report. You can use this activity report to work out where the message went in the queue manager network. To prevent queue manager applications generating activity reports, click Disabled; to enable queue manager applications to generate activity reports, clickMessage or Queue. If you click Message, a queue manager application that generates an activity report puts the report on the queue that the originator of the message requested in the ReplyToQ and ReplyToQMgr fields of the message descriptor; if you click Queue, a queue manager application that generates an activity report puts the report on the system queue SYSTEM.ADMIN.ACTIVITY.QUEUE. If you make changes to this attribute, you must stop and restart any channels to which you want the changes to apply. | ACTIVREC |
| Trace-Route recording | You can use Trace-Route messages to determine the routes that messages take through a queue manager network. Participating queue manager applications can generate information about the route and put the information in activity reports. The queue manager applications can also add the information to the Trace-Route message itself, depending on the options set in the Trace-Route message. The Trace-Route message can then accumulate chronological information about the route. The Activity recording attribute specifies on which queue the activity reports are put. The Trace-route recording attribute controls the accumulation of information in the Trace-Route message itself. To prevent the queue manager appending route information within the Trace-Route message and from returning information in reply messages, click Disabled. To enable queue manager applications to add the route information to the Trace-Route message, click Message or Queue. If you click Message and a queue manager application generates a reply message containing the accumulated route information from the Trace-Route message, the queue manager application puts the reply message on the queue that the originator of the message requested in the ReplyToQ and ReplyToQMgr fields of the message descriptor; if you click Queue and a queue manager application generates a reply message containing the accumulated route information from the Trace-Route message, the queue manager application puts the reply message on the system queue SYSTEM.ADMIN.TRACE.ROUTE.QUEUE. If you make changes to this attribute, you must stop and restart any channels to which you want the changes to apply. | ROUTEREC |

To generate inhibit event messages, click Enabled; to prevent the queue manager generating inhibit event messages, click Disabled. | INHIBTEV |
| Local events | When an application or the queue manager has not been able to access an object, for example because the object has not been defined, the queue manager can generate a local event message. To generate local event messages, click Enabled; to prevent the queue manager generating local event messages, click Disabled. | LOCALEV |
| Remote events | When an application or the queue manager cannot access a queue on another queue manager, for example the transmission queue is not correctly defined, the queue manager can generate a remote event message. To generate remote event messages, click Enabled; to prevent the queue manager generating remote event message, click Disabled. | REMOTEEV |
| Start and stop events | When a queue manager starts, or has been requested to stop or quiesce (z/OS supports only start), the queue manager can generate a start and stop event message. To generate start and stop event messages, clickEnabled; to prevent the queue manager generating start and stop messages, click Disabled. | STRSTPEV |
| Performance events | When a resource reaches a threshold condition, for example a queue depth limit has been reached, the queue manager can generate a performance event message. To generate performance event messages, click Enabled; to prevent the queue manager generating performance event messages, click Disabled. | PERFMEV |
| Command events | When an MQSC command or PCF command is executed successfully, the queue manager can generate command event messages.

|---|---|---|
| *Log type | Read-only. This attribute shows the type of logging that the queue manager uses. You cannot change the type of logging after the queue manager is created. | LogType |
| *Log path | Read-only. This attribute shows the location of the queue manager's logs. You cannot change the value of theLog path attribute after the queue manager is created. | LogDefaultPath |
| *Log file pages | Read-only. This attribute shows the number of 4 KB pages in the log file. For example, if the value is 256, the file size is 1 MB.
The default value is 4096, the file size 16 MB.
| LogFileSize |
| *Log primary files | These are the log files that are allocated when the queue manager is created.
On Windows, type the number, from 2 to 254, of primary log files. The default value is 3. The total number of primary and secondary log files must not exceed 255 and must not be less than 3.
On UNIX and Linux, type the number, from 2 to 510, of primary log files. The default value is 3. The total number of primary and secondary log files must not exceed 511 and must not be less than 3.
The value is examined when the queue manager is created or started. You can change the value after the queue manager has been created but the change is not effective until the queue manager is restarted.
| LogPrimaryFiles |
| *Log secondary files | These are the log files that are allocated when the primary files are exhausted.
On Windows, type the number, from 1 to 253, of secondary log files. The default value is 3. The total number of primary and secondary log files must not exceed 255 and must not be less than 3.

| *Log buffer pages | Type the number, from 0 to 4096, of 4 KB buffer pages for writing. If you type a number from 1 to 17, the minimum of 18 (72 KB) is used. If you type a number from 18 to 4096, that number of pages is used. If you type 0, the queue manager selects the size. In WebSphere MQ for Windows Version 7.0 and alter, this is 512 (2048 KB).
The default value is 0 (Which the queue manger selects as 512 (2048 KB). If you change the value of this property, restart the queue manager to apply the change.
| LogBufferPages |
| *Log write integrity | This is the method that the logger uses to reliably write log records. If you are using a non-volatile write cache (for example, ssa write cache enabled), it is safe for the logger to write log records in a single write, so clickSingleWrite; if you need to write log records with more integrity, click DoubleWrite to use an additional write; if you need to write log records with complete integrity but at the cost of performance, click TripleWriteto use another additional write. | LogWriteIntegrity |
XA resource managers (not z/OS)
The following table lists the attributes that you can set on the XA resource manager page of the Queue Manager properties dialog. The XA resource manager page displays attributes to edit if the queue manager coordinates its own units of work along with database updates; for example, the name of the resource manager (the database) and the location of the switch file, which helps the WebSphere MQ communicate with the database. The attributes on the XA resource manager page relate to the XAResourceManager stanza in the configuration files.
| Attribute | Meaning | Stanza key |

The default is a zero-length string. | XAOpenString |
| *XACloseString | You can type a string of data that WebSphere MQ passes in its calls to the database manager's xa_close function. WebSphere MQ and the queue manager call the xa_close function when the queue manager starts and when you make a call to MQDISC in your WebSphere MQ application process, having earlier made a call to MQBEGIN. The default is a zero-length string. It is common to have a zero-length string. | XACloseString |
| *ThreadOfControl | The queue manager uses this value for serialization purposes. If the database client allows threads to call the XA functions without serialization, the value for ThreadOfControl can be THREAD. If the database client does not allow threads to call its XA functions in this way, the value for ThreadOfControl must bePROCESS. The default is PROCESS. | ThreadOfControl |

Distributed platforms, such as Windows, UNIX and Linux (x86 and x86-64 platforms)
On distributed platforms, the attributes on the Channels page relate to stanzas in the configuration files. You cannot edit this attributes on remote distributed queue managers.
| Attribute | Meaning | Stanza key |
|---|---|---|
| *Max channels | Type the maximum number of channels, from 1 to 9 999, that can be current (including server-connection channels with connected clients). For z/OS, the value must be between 1 and 9999, with a default value of 200. For all other platforms, the value must be between 1 and 65535, with a default value of 100. On a production system, you could use, for example, the value 1000. If the value of this attribute is reduced, any current channels that exceed the new limit continue to run until they stop. | MaxChannels |
| *Max active channels | Type the maximum number of channels that can be active at any one time. The default is the value specified for the MaxChannels attribute. For z/OS, the value must be between 1 and 9999. For all other platforms, the value must be between 1 and 65535. | MaxActiveChannels |
| *Max initiators | Type the maximum number of initiators allowed. The default and maximum value is 3. | MaxInitiators |
| *MQI bind type | Select the type of connection that channels use to connect to applications. To connect using a standard connection, click STANDARD; to connect without using an agent process, click FASTPATH. | MQBindType |
| *Adopt new MCA | This attribute specifies whether an orphaned MCA instance is adopted (restarted) when a new inbound channel request is detected that matches the value of the Adopt new MCA check attribute.
To adopt all channel types, type All. If a FASTPATH channel cannot be safely ended, it is not ended and the adoption fails.
If you do not require orphaned channels to be adopted, type No. | AdoptNewMCAType |
| *Adopt new MCA check | This attribute specifies which elements are checked to determine whether an MCA should be adopted when a new inbound channel is detected with the same name as an already active MCA. Type one or more of the following values separated by commas:
| AdoptNewMCACheck |
| *Adopt new MCA timeout | Type the number of seconds, from 1 to 3600, that the new process must wait for the old process to end. The default value is 60. | AdoptNewMCATimeout |
| *Pipeline length | To allow an MCA to transfer messages using multiple threads, type the number of concurrent threads that the channel will use. The default is 1; if you type a value greater than 1, it is treated as 2. Make sure that you configure the queue manager at both ends of the channel to have a Pipeline length that is greater than 1. Pipelining is effective only for TCP/IP channels. | PipeLineLength |
z/OS platform
On z/OS, the attributes are not configuration attributes; they are just ordinary queue manager attributes like all the other attributes in thez/OS queue manager's properties dialog.
| Attribute | Meaning | MQSC parameter |
|---|---|---|
| Active channels | Type the maximum number of channels, from 1 to 9999, that can be active at any one time. The default value is 200. The value must not be greater than the value of MAXCHL that defines the maximum number of channels allowed. | ACTCHL |
| Channel initiator adapters | Specify the number of adapter subtasks, from 0 to 9999, to use for processing WebSphere MQ calls. As a guide, the ratio of adapters to dispatchers should be approximately 8 to 5. However, if you have only a small number of channels, you do not have to decrease the value of this parameter from the default value. Suggested settings: 8 (default) for a test system; 20 for a production system. Specifying a value of 20 adapters gives greater parallelism of WebSphere MQ calls. This is important for persistent messages. Specifying fewer adapters might be better for nonpersistent messages. | CHIADAPS |
| Adopt new MCA check | This attribute specifies which elements are checked to determine whether an MCA should be adopted when a new inbound channel is detected with the same name as an already active MCA. Enter one or more of the following values separated by commas. To check the queue manager name and the network address to prevent your channels from being inadvertently shut down, click ALL; to check the network address, click Network address; to check the queue manager name, click Queue manager name; to do no checking, click NONE. | ADOPTCHK |
| Adopt new MCA type | This attribute specifies whether an orphaned instance of an MCA of a particular channel type should be restarted automatically when a new inbound channel request matching the adopt new MCA check parameters is detected. This attribute is read-only. | ADOPTTYPE |
| Channel initiator dispatchers | Specify the number of dispatchers to use for the channel initiator, from 1 to 9999. As a guideline, allow one dispatcher for every 50 current channels. If you have a small number of channels, however, use the default value of 5. If you are using TCP/IP, the maximum number of dispatchers used for TCP/IP is 100, even if you specify a large value for this attribute. You are recommended to specify a value of 20 on production systems in order to handle up to 1000 active channels. Restart the channel initiator to apply changes to this attribute. | CHIDISPS |
| Register with WLM | Specify whether the TCP listener that handles inbound transmissions for the queue-sharing group should register with WLM/DNS. To specify that the listener is not to register with Workload Manager, click No; to specify that the listener is to register with Workload Manager, click Yes. | DNSWLM |
| Listener timer | Specify the time interval, in seconds from 5 to 9999, between attempts by WebSphere MQ to restart the listener after an APPC or TCP/IP failure. When the listener is restarted on TCP/IP, it uses the same port and IP address as it used when it first started. Changes to this attribute take effect for listeners that are subsequently started. Listeners that are currently started are unaffected by changes to this attribute. | LSTRTMR |
| Channels using LU6.2 | Specify the maximum number of channels that can be current, or clients that can be connected, that use the LU 6.2 transmission protocol. Type a value from 0 to 9999. If you type 0, the LU 6.2 transmission protocol is not used. The value must not be greater than the value of MAXCHL that defines the maximum number of channels allowed. | LU62CHL |
| Maximum channels | Type the maximum number of channels, from 0 to 9999, that can be current (including server-connection channels with connected clients). The default value is 200. On a production system, you could use, for example, the value 1000. If the value of this attribute is reduced, any current channels that exceed the new limit continue to run until they stop. The values of ACTCHL, LU62CHL, and TCPCHL must not be greater than the maximum number of channels. | MAXCHL |
| Lowest port address | Type the lowest port number, from 0 to 65535, to be used when binding outgoing channels. When all the port numbers between the value of the Lowest port address attribute and the Highest port address attribute have been used, outgoing channel bind to any available port number. The default is 0, which means that all outgoing channels bind to any available port number. Changes to this attribute take effect for channels that are subsequently started. Channels that are currently running are unaffected by changes to this attribute. | OPORTMIN |
| Highest port address | Type the highest port number, from 0 to 65535, to be used when binding outgoing channels. When all the port numbers between the value of the Lowest port address attribute and the Highest port address attribute have been used, outgoing channel bind to any available port number. The default is 0, which means that all outgoing channels bind to any available port number. Changes to this attribute take effect for channels that are subsequently started. Channels that are currently running are unaffected by changes to this attribute. | OPORTMAX |
| Receive timeout | Specify the approximate length of time that a TCP/IP channel waits to receive data, including heartbeats, from its partner before returning to the inactive state. This attribute applies only to message channels, and not MQI channels. See also the Receive timeout type attribute for more information. | RCVTIME |
| Receive timeout type | Set this attribute to specify how the value of the Receive timeout attribute is interpreted. To specify that theReceive timeout value is a multiplier to be applied to the negotiated Heartbeat interval value to determine how long a channel is to wait, set the Receive timeout type attribute to Multiply, then specify a Receive timeoutvalue of zero or in the range 2 through 99 (if you specify zero, the channel does not time out its wait to receive data from its partner); to specify that Receive timeout value is the number of seconds to be added to the negotiated Heartbeat interval value to determine how long a channel is to wait, set Receive timeout type toAdd, then specify a Receive timeout value in the range 1 through 999999; to specify that the Receive timeoutvalue is the number of seconds that the channel is to wait, set Receive timeout type to Equal, then specify anReceive timeout value in the range zero through 999999 (if you specify zero, the channel does not time out its wait to receive data from its partner). | RCVTTYPE |
| Minimum receive timeout | Type the minimum length of time, in seconds from 0 to 999999, that a TCP/IP channel waits to receive data, including heartbeats, from its partner before returning to an inactive state. This attribute applies only to message channels, and not to MQI channels. If you use the Receive timeout type attribute to specify that the TCP/IP channel wait time is relative to the negotiated value of the channel's Heartbeat interval value and the resultant value is less than the value of this attribute, the value of this attribute is used. | RCVTMIN |
| Channels using TCP | Type the maximum number of channels that can be current, or clients that can be connected, that use the TCP/IP transmission protocol. Type a value from 0 to 9 999 (although note that TCP/IP might not support as many as 9 999 channels). If you type 0, the TCP/IP transmission protocol is not used. The value must not be greater than the value of MAXCHL that defines the maximum number of channels allowed. | TCPCHL |
| TCP keepalive | Specify whether the Keepalive facility is used to check that the other end of the connection is still available. If it is not available, the channel is closed. To specify that the Keepalive facility is not to be used, click No; to specify that the Keepalive facility is to be used as specified in the TCP profile configuration data set, click Yes (the interval is specified in the Keepalive Interval attribute on the Extended page of the Channel properties). | TCPKEEP |
| TCP stack type | To specify that the channel initiator uses only the TCP/IP address space that is specified in the TCP name attribute, click Single; to specify that the channel initiator can use multiple TCP/IP address spaces, and the default value is the value of the TCP name attribute, click Multiple. | TCPSTACK |
| Channel initiator trace auto start | To specify that the channel initiator trace starts automatically, click Yes; to specify that the channel initiator trace does not start automatically, click No. Changes to this parameter take effect when the channel initiator is restarted. If you need to start or stop channel initiator trace without restarting the channel initiator, use the Trace dialog after the channel initiator has started. To open the Trace dialog, in the Navigator view, right-click WebSphere MQ, then click Trace | TRAXSTR |
| Channel initiator trace table size | Type the size, in megabytes from 2 to 2048, of the channel initiator's trace data space. Note that changes to this attribute take effect immediately; any existing trace table contents are lost. When you use large z/OS data spaces, ensure that sufficient auxiliary storage is available on your system to support any related z/OS paging activity. You might also need to increase the size of your SYS1.DUMP data sets. | TRAXTBL |
| DNS group name | Type the name of the group that the TCP listener handling inbound transmissions for the queue-sharing group should join when using Workload Manager for Dynamic Domain Name Services support (WLM/DNS). The maximum length of this parameter is 18 characters. If this name is blank, the queue-sharing group name is used. Changes to this attribute take effect for listeners that are subsequently started. Listeners that are currently started are unaffected by changes to this attribute. | DNSGROUP |
| LU group name | Type the generic LU name to be used by the LU 6.2 listener that handles inbound transmissions for the queue-sharing group. The maximum length of this parameter is 8 characters. If this name is blank, the listener cannot be used. Changes to this attribute take effect for listeners that are subsequently started. Listeners that are currently started are unaffected by changes to this attribute. | LUGROUP |
| LU name | Type the name of the LU to use for outbound LU 6.2 transmissions. Set this to be the same as the name of the LU to be used by the listener for inbound transmissions. The maximum length of this parameter is 8 characters. If this name is blank, the APPC/MVS default LU name should be used. This is variable, so the LU name attribute should always be set if you are using LU 6.2. | LUNAME |
| LU6.2 member name suffix | Type the suffix of the APPCPM member of SYS1.PARMLIB. This suffix nominates the LUADD for this channel initiator. | |
| TCP name | Type the name of either the only, or the default, TCP/IP system to be used, depending on the value of the TCP stack type attribute. This is the name of the z/OS UNIX System Services stack for TCP/IP, as specified in the SUBFILESYSTYPE NAME parameter in the BPXPRMxx member of SYS1.PARMLIB. The default value is TCPIP. The maximum length of this parameter is eight characters. Changes to this parameter take effect when the channel initiator is restarted. | TCPNAME |
| Channel initiator service parm | This parameter is reserved for use by IBM. | CHISERVP |

Keep. The undelivered non-persistent message is not discarded. The Pub/Sub Engine will continue to retry to process this message at appropriate intervals and does not continue processing subsequent messages.
| PSNPMSG |
| Undelivered non-persistent response | This property defines what the Pub/Sub engine should do with non-persistent responses that are not delivered. The four options are:
Discard. The undelivered non-persistent response is discarded if it cannot be placed on the reply queue.
Keep. The undelivered non-persistent response is not discarded or put on the dead-letter queue. The Pub/Sub Engine will back out the current operation and then retry it at appropriate intervals and does not continue processing subsequent messages.
Normal. Non-persistent responses which cannot be placed on the reply queue are put on the dead-letter queue. If they cannot be placed on the DLQ then they are discarded. This is the default value.
Safe. Non-persistent responses which cannot be placed on the reply queue are put on the dead-letter queue. If the response cannot be sent and cannot be placed on the dead-letter queue then the Pub/Sub Engine will back out of the current operation and then retry at appropriate intervals and does not continue processing subsequent messages.
| PSNPRES |
| Tree lifetime | The lifetime, in seconds of non-administrative topics. When this non-administrative node no longer has any active subscriptions, this parameter determines how long the queue manager will wait before removing that node.
