Small World

You may have noticed that I didn’t include any info on the presenter in the blog entry on IBM web conference on CICS Performance Basics … Dan Zachary’s name sounded familiar, but I could not recall anything about him.

I shot Dan an email, and it turns out that Dan works in CICS Level 2 Support, and he assisted me with a PMR back in 2003. (I believe that was the last PMR I worked on; it’s been ETR’s since.) On this PMR, we had a linked program that was abending; it had a GOBACK coded instead of an EXEC CICS RETURN. Changing the GOBACK to an EXEC CICS RETURN was a workaround, but IBM was able to provide a fix to allow the code to run with the GOBACK. It turned out to be an LE issue, but Dan was very helpful in making that determination.

Now-a-days a GOBACK is handled same as an EXEC CICS RETURN … Anyone else remember when issuing a GOBACK in CICS caused CICS to terminate? Instead of returning back to the calling program, it returned control back to the operating system. I do not recall when that was changed, but I still pause when I see a GOBACK in CICS application code.

Anyway, Dan is an Advisory Software Engineer with IBM and has worked with CICS Level 2 Support for going on 20 years. He knows what he’s talking about – be sure and catch the web conference if you can! I’ll have to miss the original broadcast, but will catch up when it is made available for replay.

Free IBM Web Conference – CICS Performance Basics

On February 3, at 11 a.m. EST, Dan Zachary will be presenting a free web conference on CICS Performance Basics.  According to the write-up, he will be focusing on the most important CICS performance monitoring fields, including how to access them in a dump and how to use them to identify the source of performance issues. Sounds like a great topic, and should be well-worth the time. By the way, the price is right (did I mention that it’s FREE?).

I have a meeting scheduled that conflicts with this, so I’m hoping someone can post a review to let us that can’t attend know how it went. Hopefully IBM will be making the web conference available for replay sometime afterwards.
