You all are going to like this.. something that has been needed for a while now.
If you wanted to be able to determine if you have workload running on a general purpose engine (CP) that could have been eligible to run on a zIIP specialty if you had one installed and you wanted this information in your DB2 accounting reports, you wish has been been granted…… Continue reading »
Even though something may be working as designed doesn’t necessarily mean it’s working as expected. This always seems to happen around performance stuff to me. In my experience, something that has unexpected performance can be far worse than something that has bad performance. Often, bad performance can be explained and possibly even corrected. However, when stuff happens out of the blue and catches you completely off guard, these can be the problems that can turn into real challenges to resolve…… Continue reading »
You’re running DB2 for z/OS on the mainframe and you know all about the zIIP (System z Integrated Information Processor) specialty engine. You know that every MIP you can redirect to a zIIP has the potential to reduce your software cost because many products charge by the CPU capacity you have on your processors, the number of general purposes engines (CPs). Having 3 CPs and 1 zIIP is kind like having the computing power of 4 processors. Of course, you already knew that that…… Continue reading »
We have been waiting for the arrival of this APAR for quite some time. Getting to single enclave support for query parallelism is a pretty big deal, well for at least anyone messing around with parallelism and Workload Manager (WLM) it is. Let me explain to you why….. Continue reading »
What a great title for a blog post.
Did it get your attention? I certainly hope so.
Improving how much work is redirected to a System z Integrated Information Processor (aka: zIIP) should always be a very big deal. At least in my opinion, it should be….. Continue reading »
