It used to be that formatting a CICS Auxiliary Trace dataset meant submitting batch jobs to run the trace formatting utility DFHTUxxx. MANY batch jobs.   First a run to get the abbreviated trace, so you could see what the time range the trace dataset covered, and perhaps get some task numbers. Then another run, limiting the time range or task numbers formatted to ones you were interested in. Then yet another job to format only selected trace entries.   I was pleasantly surprised when I recently discovered that the IBM Fault... [More]

  Are you preparing for your next z/OS upgrade? Do you need to confirm if your CICS Transaction Server (CICS TS) or one or more of your CICS Tools is compatible or needs any additional maintenance? Does your site's IT governance policy require you to contact your software providers to confirm there are no compatibility issues for the z/OS upgrade? These questions are typical in most shops, and very often when working with IBM, you may use the IBM Support Portal to open an SR (Service Request) to ask what if any compatibility or... [More]

  WebSphere MQ V7.1 introduced a channel security feature called Channel Authentication Records, or CHLAUTH for short. The feature allows you to set rules to indicate what should happen to inbound connections to your queue manager. By default there are three rules in place and one of them is there to block all remote privileged users - that is those in the mqm group for example. To understand whether you are being blocked by this particular rule see " I'm being blocked by CHLAUTH - how can I work out why? "   AMQ8878:... [More]

  With the new feature in WebSphere MQ V7.1 called Channel Authentication Records (or CHLAUTH for short) there is a lot of talk about privileged users and administrator access. In this post I want to discuss how to create a non-privileged MQ administrator. Before I begin let me define what I mean by each of those terms.   Privileged user A privileged user is a user that has authorization to do an operation without being explicitly granted access to do that operation. The users in the mqm group are examples of these privileged users,... [More]

Clustering is a WebSphere MQ feature that is often confusing for many users.  I’d like to provide some guidelines you can follow to ensure the optimum health for your cluster. Here’s a list of Ten Tips for MQ Clustering: Don’t issue refresh command unless absolutely necessary. The REFRESH CLUSTER command can cause temporary disruption to traffic as it clears out the local cache. It is not a command that should be issued on a routine basis. Have 2 Full Repositories (no more, no less). When updates are made within a cluster, two messages are sent... [More]

What is a WSTE?   Well, in our context, WSTE stands for WebSphere Support Technical Exchange .  If you haven't heard of it before, it's a great program that can help you get the most out of your software. One of the best ways to stay informed and learn about your products is to attend the FREE WebSphere Support Technical Exchange webcasts.  Topics are scheduled throughout the year on many IBM products and different functional areas of each product.  But... what if you missed a webcast, or your schedule didn't allow you to call-in for the live...

Every queue manager should have a dead-letter queue (DLQ). What happens when a message cannot be delivered to the destination queue? Local puts If the message is put to a local queue and the message can't be delivered, then the MQPUT fails.  A reason code is returned to the putting application and the application will need to handle, or manual intervention might be required. Remote puts If a receiving channel cannot put the message to its destination queue, then it is placed on the dead letter queue, if one has been defined. If no dead letter... [More]

  If Graphical capabilities are not available on the system, then the response file in silent mode can be used to install/uninstall/rollback. Installation Manager (IM)  itself can be installed in silent mode, and then subsequent operations (such as installing or uninstalling) can also be performed in silent mode. Silent mode uses XML-formatted response files as input and can perform multiple operations in a single operation. Here is a sample command to run response file: imcl -acceptLicense input <RESPONSEFILE>.xml -log... [More]

  Many of us are familiar with the traditional IBM Installation Manager (IIM) Eclipse-based rich client, IBMIM , that allows one to drive IIM in an environment where a GUI is available. However, this approach is not always feasible, especially in an environment where one needs to access IIM on a remote server, perhaps one without a GUI console i.e. operating in so-called "headless" mode. This is often the case with remote UNIX® servers ( AIX, Linux, Solaris etc. ) where one's only point of access is via a remote terminal... [More]

  If there is still free memory in the system when a native out-of-memory error occurs, then the problem is likely to be a shortage of memory in the low-memory region (under 4GB). Although the Java heap can be located above this boundary, other data, which are associated with Java objects, are located in the lower memory segments. Specifically these are the memory segments associated with threads, classes and monitors.  See the following related content: Using -Xgc:preferredHeapBase with -Xcompressedrefs  ... [More]
