Deprecated: Such a cool word yet a word so misunderstood

By Willie DB2 for z/OS (General), DSNZPARM, Migration Comments Off

I wanted to talk about the DSNZPARM keys deprecated in DB2 10.  And yes I do realize that I listed them out in a previous post.  However, this time I wanted to discuss why it’s important today, maybe even before migrating to DB2 10, to plan on how their eventual departure from DB2 may affect you.

Then someone pointed out to me that sometimes when we say something is “deprecated” in a future release of DB2, it can sometimes get misinterpreted, or misunderstood.  In fact, there has been extra verbiage added to the DB2 10 Installation and Migration Guide (GC19-2974) to help alleviate future misunderstandings…… Continue reading »

DB2 10 prerequisites; or least some of them

By Willie DB2 10 for z/OS, DB2 9 for z/OS, DB2 for z/OS Version 8, Migration Comments Off

DB2 10 has been around for a year now.  Everyday we hear of another customer starting their migration planning process.  With that in mind, I thought I should mention what the minimum requirements are to upgrade to DB2 10 for z/OS.   Some of the requirements, like operating system level and machine type, are not things you can “just take care of” over a weekend.   It’s almost as though you need a plan for what has to be completed before you can implement you migration plan.   That stuff you need to start thinking about today is today’s topic of discussion…… Continue reading »

And then temp work files and sort work files became just one

By Willie DB2 10 for z/OS, DB2 9 for z/OS, DSNZPARM, Migration Comments Off

It was way back in DB2 9 that temp work files and sort work files were combined, or converged as the Redbook explains it.   It all seemed like a good idea at the time, and it probably was, but there were still a few issues with the original implementation that have just been recently worked out last summer.  The particular issue resolved last summer also just happened to be something I had the opportunity to experience first hand.  Unfortunately, the fix wasn’t available at the time.  Fortunately, we picked up on the error early on so when we had the problem we were able to immediately fix it…… Continue reading »

The PDSE data set type is here to stay if you are DB2 9 or above

By Willie DB2 10 for z/OS, DB2 9 for z/OS, Migration Comments Off

Back in the day of DB2 Version 8 installations, there was this thing going around that you might have to use PDSE for DB2.   It turned that was not true, at least not true at the time for Version 8.  However, as time (and releases) change, so do the rules of what you need and don’t need.  As of DB2 9, PDSE is required for certain target and distribution libraries in addition to a few SMP/E libraries…… Continue reading »

Are you starting to think about upgrading to DB2 10?

By Willie DB2 10 for z/OS, DB2 9 for z/OS, DB2 for z/OS Version 8, Migration Comments Off

Is DB2 10 on your mind lately?   Are you thinking maybe it’s about time to at least start putting a migration plan to DB2 10 in place?   If so, that’s great.   If not, why?  You do realize that DB2 10 went generally available back on October 22, 2010, that’s just about one (1) year ago.  It’s really not a “brand new” release anymore.   And the number of customers jumping on the DB2 10 migration bandwagon has started to accelerate the last few months…… Continue reading »

A DB2 10 Upgrade DSNZPARM Tip / APAR

By Willie DB2 10 for z/OS, Migration Comments Off

 
DB2 10 has a lot of very nice new features in it.  One such feature is the ability to make LOAD, COPY, REORG, and REBUILD always use FLASHCOPY, even when not specified in the utility control cards.

DB2 10 introduces five new DSNZPARM keywords that turn on/off this new default FLASHCOPY ability…… Continue reading »

Yes, you can do DB2 V8 to DB2 10, but SHOULD you skip DB2 9; the story continues?

By Willie DB2 10 for z/OS, DB2 9 for z/OS, DB2 for z/OS Version 8 Comments Off

One of the interesting (and unexpected in my opinion) features of DB2 10 for z/OS is a customer’s ability to upgrade to DB2 10 directly from DB2 Version 8 new function mode (NFM), without having to go through DB2 9.   It’s a little something referred to as skip-level migration. Of course, DB2 10 still allows the more traditional upgrade path from DB2 9 NFM.  Now you all just have the additional option of a skip-level migration from DB2 V8 NFM…… Continue reading »
