An interesting title for a blog post?  The word “update” implies I have discussed real time statistic before; I have not.  Although, I wish I had.  In fact, it’s getting ever more difficult to come up with an original DB2 for z/OS subject to write about. It sometimes seems like everything has been done, been discussed, been explained; and at least a couple of times by now.   This blogging stuff was so much easier when I had the only blog that covered DB2 for z/OS.  Now there are a bunch of these blogs; they’re everyplace.  Unfortunately, I must admit that a couple of them a pretty good.  It’s difficult for me to write about something that someone else has already done a great job describing.

The Setup

Today’s blog post discusses two DSNZPARM keywords (MAXCONQN and MAXCONQW on the DSN6FAC macro) that were introduced on December 13, 2012 via APAR PM43293 to improve management of (distributed) database access threads (DBATS).  However, before we (that proverbial group of nonexistent people that live in my head that always tend to volunteer me for stuff that always seems to get me into trouble) get into the details of these two new system parameters, I thought it would be prudent to review a few of the existing distributed terms (like DBAT) and a few DSNZPARM keywords that are used in APAR PM43293’s cover and in today’s blog post: MAXDBAT and CONDBAT on the DSN6SYSP macro and CMTSTAT on the DSN6FAC macro.

2012 comes to an end today.  Many have the day off, some don’t but aren’t getting much work done anyway, yet others still have things to complete to finish up their year.   With all that in mind, I thought a short yet still handy post would be perfect to cap off the year.

Anyone who has ever messed around with tuning DB2 for z/OS has probably come across an IFCID (instrumentation facility component identifier)  at one point or another.  In fact, I did a blog post back in May 2010 discussing DSNWMSGS (Instrumentation Facility Component Identifier )  In fact, DB2’s IFCIDs have information on just about any DB2 for z/OS metric you could possibly be interested in, and new ones are added all the time and the current ones are always being expanded.

It looks like an all DSNZPARM APAR Friday today.   I have two APARs, both dealing with ZPARMs in one way or another, one is a HIPER, and both sound pretty interesting.
