The latest  firmware update for the MQ Appliance (8.0.0.4) contains a number of new features, which are summarized in an earlier blog post. In this article I'll take a more detailed look at the browser based file management. The "copy" command in the "config" section of the CLI can be used to transfer files to and from the MQ Appliance, but entering long filenames and getting the syntax exactly right can be time consuming, so having a browser based version can often be easier to use. After logging into the Web UI, the existing actions on the top menu are "Manage Appliance" and "MQ Console". The new "File Management" action has been added between the two. Selecting this action  navigates to the main file browsing page: So for example if you wanted to upload new certificates for the Web UI to use, you would select "Actions > Upload Files" for the "cert:" entry. This gives the following view,

Verifying  Queue Managers SSL Configuration with MQCERTCK. Tweet MQCERTCK is the updated version of the MH03 SupportPac that is now included in MQ as of version 8.0.0.4. MQCERTCK is a tool to look for common mistakes in your Queue Manager’s SSL configuration and provides recommendations for resolving problems. It will check: Existence and permissions of Queue Manager’s Key Repository referenced in the Queue Manager SSLKEYR attribute Existence and validity of Queue Manager’s certificate referenced in the Queue Manager CERTLABL attribute. Existence and validity of any certificates referenced in SSL enabled channel’s CERTLABL attributes. Client applications key repository and certificates, including checking the certificates are authorised with the Queue Manager. It is available on all Distributed platforms and the MQ Appliance but is not available currently on z/OS or IBMi, additionally th

Demonstration videos Using Charts with the IBM MQ Appliance and MQ Console Configuring an HA Group on Two IBM MQ Appliances Abstract This IBM Redbooks publication describes the IBM MQ Appliance M2000, an application connectivity option that combines secure, reliable IBM MQ messaging with the simplicity and low overall costs of a hardware appliance. This book presents underlying concepts and practical advice for integrating the MQ Appliance M2000 into an existing IBM MQ infrastructure. It is therefore aimed both at enterprises that are considering a possible first use of MQ and the MQ Appliance M2000 as well as those that have already identified the appliance as a logical addition to their messaging environment. Details about new functionality and changes in existing approaches to application messaging are described where appropriate. The authors' goal is to help readers make informed design and implementation decisions so that they can successfully integ

Creating a log file when you install or uninstall WebSphere MQ WebSphere MQ for Windows is installed using the Microsoft Installer (MSI). If you install the MQ server or client through launchpad , MQPARMS or setup.exe , then a log file is automatically generated in %temp% during installation. Alternatively you can supply parameters on the installation MSI command msiexec to generate a log file, or enable MSI logging system-wide (which generates MSI logs for all install and uninstall operations). If you uninstall through the Windows Add/Remove programs option, no log file is generated. You should either uninstall from the MSI command line and supply parameters to generate a log file, or enable MSI logging system-wide (which generates MSI logs for all install and uninstall operations). For details on how to enable MSI logging, see the following article in the WebSphere MQ product documentation: Advanced installation using msiexec For details on how to enable system-w

Different types of bindings IBM MQ supports two ways that an application can connect: 1. Local bindings : This is when the application and queue manager are on the same operating image. CHLAUTH is not relevant to this type of application connection. 2. Client bindings : This is when the application and queue manager use the network to communicate. The application and queue manager may be running on the same machine or they may be on different machines. In MQ a client connection is handled in the form of a server-connection (SVRCONN) channel. Both CONNAUTH and CHLAUTH are applicable, and it is this type of connection which is discussed. The binding steps of a receiving end of a channel When an application connects to a queue manager there is a lot of checking to perform to ensure that both ends of the channel understand what is supported by the other end. The receiving end does some extra checking to ensure that the client is allowed to connect. This checking involves

New runmqsc features added in MQ 8.0: non-Administrators, client connection, CCDT, authentication The purpose of this techdoc is to provide examples of the new features added to the "runmqsc" command in IBM MQ 8.0. You use runmqsc to issue MQSC commands to a queue manager. New runmqsc features in MQ V8.0 support customizable prompt, "quit", access by non-Administrators, client connection, CCDT, and authentication The chapters are: Chapter 1: Quick summary of commands Chapter 2: Usability: customizable prompt, using 'quit' or 'exit' as synonym for 'end' Chapter 3: Non-administrators (not in the group 'mqm') can now use runmqsc Chapter 4: Flag -u to allow authentication Chapter 5: Flag -c to allow remote access through a client connection Chapter 6: Flag -n to allow the modification of a local CCDT file New runmqsc features added in MQ V8.pdf

You have noticed that the IBM MQ product now takes a stance to have security features turned on by default. many of you will have undoubtedly tripped over CHLAUTH rules blocking you because you asserted a privileged user ID over a client connection, or more recently when playing with V8, you may have also tripped over CONNAUTH rules mandating you provided a user ID and password because you asserted a privileged user ID over a client connection. You'll have no doubt learned that to just turn off CHLAUTH and CONNAUTH completely, you can issue the following commands:- ALTER QMGR CHLAUTH(DISABLED) CONNAUTH(' ') REFRESH SECURITY TYPE(CONNAUTH) Plus, adding the user ID that is already defined on the queue manager system and in the privileged mqm group to your server-connection channel's MCAUSER field. ALTER CHAN NEL( 'SYS TEM. DEF. SVRC ONN) CHLTYPE(SVRCONN) MCAUSER('morag1') However, as you do so, you wish that you

The MQ Appliance adds a new simpler way to start collecting this trace information. It also gives you new ways to narrow down what you actually trace. Application activity trace has been available on the distributed MQ platforms since version 7.1 and is a mechanism that allows you to track exactly what an application is doing when it comes to its MQ operations. So it'll show you how they connect, what queues or topics they open and then the messages they put and get. An excellent way to diagnose a wide variety of problems. If you're already familiar with activity trace you'll know that you can enable it in a number of ways and once it's collecting trace it'll write all the trace data as a series of messages to the SYST EM.A DMIN .TRA CE.A CTIV ITY. QUEU E of the queue manager. There are multiple ways to enable activity trace, it's either through turning trace on for all applications by using the queue manager attribute ACTVTRC, or through w

IBM has provided customers with a Software Product Compatibility Reports (SPCR) tool where you can locate and find complete lists of supported operating systems, system requirements, prerequisites, and optional supported software for WebSphere MQ 8.0.   RHEL Compatible OS . Defect support is available for Linux environments that are fully compatible - both source and binary - with Red Hat Enterprise Linux V6. Unless stated otherwise, WebSphere MQ has not been specifically tested in such compatible environments. WebSphere MQ Support is therefore unable to assist in issues related to configuration and setup, or issues that are directly related to the linux environment itself. If issues arise that are related to the compatible linux environment, the user may need to contact the linux environment vendor for support, or the issue may need to be recreated inside an environment tested by IBM in order to receive WebSphere MQ support.
