Message Broker (WMB) installation and setup on Linux
Installing the Binaries
As a first step download the trail version of the message broker binaries from IBM site and install them. this part is very simple and process is depends on your operating system. Like for windows, you have .exe file and Linux has rpm and unix you get pkg or other.
After installation
Set up a broker database
[Windows]
__ 1. Create the broker database, BRKDB.
Open a WebSphere Message Broker Command Console: mqsicreatedb BRKDB
This command also establishes the required ODBC connection.
_ 2. Verify your user account for the broker database.
[Linux]
If you are creating Oracle databases for 32-bit brokers on Linux® and UNIX® systems, run the mqsi_setupdatabase command before you create a database.
mqsi_setupdatabase– Database–Database_Home_Directory
Eg:mqsi_setupdatabase oracle /oracle/product/9i/Db_1
Add $ORACLE_HOME/lib to the end of the MQSI_LIBPATH library search path environment variable
Connecting to a database from Linux/Unix
- Copy the odbc32.ini sample file that is supplied in the install_dir/ODBC32/V5.3 directory to a location of your choice; for example, copy the file to your user ID’s home directory.
- Ensure that the odbc32.ini file has file ownership of mqm:mqbrkrs, and has the same permissions as the supplied odbc32.ini sample file.
- Set the ODBCINI32 environment variable to point to your odbc32.ini file, specifying a full path and file name. For Linux on x86 only, use the ODBCINI environment variable. On AIX®, HP-UX, Solaris on SPARC, and Linux on x86-64, set the 32-bit library search path environment variable MQSI_LIBPATH32 to show the location of the 32-bit libraries for the database manager that you are using.
For example, on AIX:
export MQSI_LIBPATH32=$MQSI_LIBPATH32:DB2_instance_directory/sqllib/lib32
On Linux on x86 only, set the 32-bit library search path LD_LIBRARY_PATH to show the location of the 32-bit libraries for the database manager.
- Edit the final stanza in the odbc32.ini file (the [ODBC] stanza) to specify the location of the ODBC Driver Manager, and to control tracing.
# In InstallDir, add the WebSphere Message Broker installation location to complete the fully qualified path to the ODBC directory. If you do not set this value correctly, the ODBC definition will not work.
# In Trace, set the value to 0; if your IBM service representative asks you to enable ODBC trace, set the value to 1.
# Start of changeIn TraceOptions, set the value to 3.End of change
# In TraceFile, type the fully-qualified path and file name to which the ODBC trace is written. Trace files can become large; specify a directory with plenty of free disk space.
# In TraceDll, add the WebSphere Message Broker installation location to complete the fully qualified path to the ODBC trace DLL.
# Accept the default values that are shown in the sample odbc32.ini file for all the other entries in the stanza.

- Edit the first stanza in the odbc32.ini file (the [ODBC Data Sources] stanza) to list the DSN of each database.
;##########################################
;###### List of data sources stanza #######
;##########################################
[ODBC Data Sources]
DB2V8DB=IBM DB2 Version 8 ODBC Driver
DB2V9DB=IBM DB2 Version 9 ODBC Driver
ORACLEDB=DataDirect 5.3 Oracle Driver
ORACLERACDB=DataDirect 5.3 Oracle Driver (Real Application Clusters)

INFORMIXDB=IBM Informix ODBC Driver
- For each database that you listed in the [ODBC Data Sources] stanza, create a stanza in the odbc32.ini file after the [ODBC Data Sources] stanza. The entries in the stanza depend on the database manager.
1. In Driver, add the WebSphere Message Broker installation location to complete the fully qualified path to the driver that is shown in the sample odbc32.ini file.
2. In Description, type a meaningful description of the database. This field is for information only, and does not affect the connection.
3. In ServerName, type the Oracle Service Name or Connect Descriptor that resolves to the target Oracle database; for example, through a mapping in the TSNAMES.ORA file.
4. Accept the default values that are shown in the sample odbc32.ini file for all the other entries in the stanza. For example:
Example:
;# Oracle stanza
[ORACLEDB]
Driver=/ODBC32/V5.3/lib/UKor823.so
Description=DataDirect 5.3 Oracle Driver
EnableDescribeParam=1
OptimizePrepare=1
ServerName=
WorkArounds=536870912
ProcedureRetResults=1
ColumnSizeAsCharacter=1
- Ensure that you have edited all three parts of the odbc32.ini file:
* The [ODBC Data Source] stanza at the top of the odbc32.ini file.
* A stanza for each data source.
* The [ODBC] stanza at the end of the odbc32.ini file.
If you do not configure all three parts correctly, the ODBC DSNs are not valid, and the broker cannot connect to the database.
Create and set up IBM WebSphere MQ v6 queue managers
Create queue manager JO, with a dead letter queue.
__ 1. Click Start –> Programs –> IBM WebSphere MQ –> WebSphere MQ Explorer.
__ 2. Right-click Queue Managers –> New –> Queue Manager.
__ a. Name = JO
__ b. Dead letter queue = JO.DLQ, click Next
__ c. For step two and step three, make no entries, simply click Next
__ d. On step four, uncheck Create Listener configured for TCP/IP
If you do not explicitly create the queue manager, the first mqsicreate command will automatically create the queue manager that you specify in the command. However, many pertinent queue manager parameters will be missing, for instance:
• A dead letter queue is not assigned.
• A listener is not activated.
• The queue manager will not start automatically.
• The queue manager will not be the default.
Should your pertinent queue manager parameters be missing, open the IBM WebSphere MQ Explorer (if not already open):
i. Right-click the top-level element in the Navigator view (that is, IBM WebSphere MQ) and select Properties. To make your Queue Manager the default, on the General page, type the name of your newly created Queue Manager in the space labeled Default queue manager name. Click Apply; click OK.
ii. From the Navigator view, right-click your new queue manager and select Properties.
iii. On the General page, select Automatic from the Startup pulldown menu. set the Type to Automatic.
iv. On the TCP page, set the TCP Port to 1414.
v. Exit the Properties pages by clicking OK.
vi. From the Navigator view, expand the Advanced options for your queue manager and select Listeners.
vii. Right-click and select New –> TCP Listener.
viii.A wizard starts, first asking you to name your listener; supply the name JO.LISTENER; click Next.
ix. On the General page, change Port to 1414; click Finish.
__e. From the Navigator view, right-click the Queues folder; right-click Select New –> Local Queue Name = JO.DLQ. Select Finish.
__ 3. Verify results by examining the state of the queue manager in the WebSphere MQ Explorer.
__ 4. Repeat these steps for the broker queue manager, JO.B with dead letter queue JO.B.DLQ, listener JO.B.LISTENER, and whose listener is to use port 1415. Remember that queue manager JO.B will not be the default queue manager.
__ 5. A queue manager cluster will assist greatly in communications between the configuration manager’s queue manager and the broker’s queue manager. Name your cluster MQSI, establish the required cluster channels and make each queue manager a cluster repository.
__ 6. Verify results by examining the state of each queue manager in the WebSphere MQ Explorer.
Create a broker, a configuration manager and a user name server
__ 1. Start up the Command Console. Start –> Programs –> IBM WebSphere Message
__ 2. Select Brokers V6.0 –> Command Console.
__ 3. Create (with the mqsicreateusernameserver command) a User Name Server on queue manager JO using service-Id jpaturi:
Note: In this and subsequent commands you are asked to enter your password (jpaturi) as the value for the -a flag. If you wish to see how password prompting works, specify -a without a value.
=>mqsicreateusernameserver -i jpaturi -a jpaturi -q JO
Create (with the mqsicreateconfigmgr command) a configuration manager on queue manager JO using service-Id jpaturi. With IBM WebSphere Message Broker V6 it is also possible to name a configuration manager. Name yours JO-CM. Link the User Name Server to the configuration manager as well.
=>mqsicreateconfigmgr JO-CM -i jpaturi -a jpaturi -q JO -s JO
__ 4. Create (with the mqsicreatebroker command) a broker (JO-BRK) on queue manager JO.B using service-Id jpaturi and broker database BRKDB. Ensure the broker can connect to the User Name Server, on queue manager JO.
=>mqsicreatebroker JO-BRK -i jpaturi -a jpaturi -q JO.B -n BRKDB -s JO -j
The -j parameter assures publish/subscribe access is enabled for the broker.
__ 5. Modify (reduce) broker properties -g (ConfigurationTimeout) and -k (ConfigurationDelayTimeout). The default values (300 and 60 seconds) are much too long for a local development environment.
=>mqsichangebroker JO-BRK -g 60 -k 15
Verify setup and start components
__ 1. Using the Command Console, list local components and verify content:
=>mqsilist
mqsiservice JOCM
mqsiservice JOBRK
mqsiservice UserNameServer
__ 2. Start services for WebSphere Message Broker; enter:
=>mqsistart JOBRK
=>mqsistart JOCM
=>mqsistart UserNameServer
It is also possible to manually start the components from the Windows Services GUI.
The GUI also permits the startup property to be set to Automatic.
__ a. Click Start –> Settings –> Control Panel –> Administrative Tools –> Services.
__ b. Right-click IBM WebSphere Message Broker component and select Properties –> Startup type.
__ c. Set the Start Type to Automatic.
__ d. Click the Start button.
__ e. Click OK.
__ f. Repeat these steps for each component.
__ 3. Verify service startup by examining the local error log using the Windows Event Viewer: Start –> Settings –> Control Panel –> Administrative Tools –> Event Viewer. Refresh the Application Log view and examine the most recent entries. Entries from the WebSphere Message Broker are identified in the Source column with the string WebSphere Broker v6.
