Abstract

How Fault Analyzer can help you view CICS TS tasks!

Body

 

In CICS Level2 support, we look at lots of dumps. Sometimes, these dumps have lots of tasks, especially when your production CICS Transaction Server for z/OS (CICS TS) region goes maxtasks or is short on storage. How can you quickly make sense of all these tasks? Fault Analyzer has some ways to help you quickly sort it all out.

 

Let's take a look at the CICS information in a CICS System dump:

Next, we will take a look at the CICS Dispatcher Domain:

Now we can view a list of all the tasks in the system dump at the time simply by selecting option 1:

Once the list of tasks is displayed, it is very simple to sort on the suspend time. Just place your cursor as shown below.

You can sort on ascending or descending.

Now quickly and almost magically, the tasks are sorted based on the time they were suspended.

This can be a very arduous task when trying to look through pages of tasks manually thru IPCS. However, with Fault Analyzer it's a breeze to see when tasks started to back-up. In this example, you'll find a number of tasks starting to backup starting at 17:35:14 for resource ICWAIT. You're one step closer to solving the problem. Split the screen and bring up IPCS with Fault Analyzer and you can have the best of both worlds!
