Re: ESQA is exhausted
Sure it depends, when we had the WMQI Brokers in full production, we had to split the Execution Groups over more than 1 STC, because they hit the 2GB ceiling.

Re: ESQA is exhausted
Once the overflow from ESQA/ECSA starts allocating below line storage, it is time to worry! An IPL will *is* imminent. Hi,It depends on your system; if there is a one job that needs large private memory you will get problem if common area is enlarged too!! Before making any change in common area you have to monitor private area usage.I think It's not so bad that you get 'ESQA is exhausted, and it overflow to ECSA'. You can continue without worry until ECSA is exhausted too; Then system will manage it automatically and after those SQA and CSA will be used. You have to monitor it only and be aware about that situation.

Re: ESQA is exhausted
I generally do not worry too much about a few hundred MB above the line when I have 2GB available to me. I *strongly* suggest you take some usage statistics and allocate both area (ECSA and ESQA) such that "normal usage" us about 30% of the allocated area.

Re: [External] ESQA is exhausted
Jason, If you stick to expanding ESQA and/or ECSA, the risk should be minimal to none. The E says extended and so unless you have address spaces bumping against the 2GB limit, making a small decrease in the above-the-line private shouldn't cause you any issues. Now, if you were talking SQA or CSA, that's a different story. :-) Rex -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Jason Cai Sent: Monday, April 16, 2018 3:53 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: [External] ESQA is exhausted Hi all We found that ESQA is exhausted, it overflow to ECSA.We want to enlarge ESQA and ECSA .

Jason Cai Jason, ESQA and ECSA are above the line, so you're probably not decreasing that 2GB space by much. If you were expanding CSA and SQA, then you need to be mindful of how much private you have below the line, since it will be allocated in 1MB increments. Increasing SQA by even 64K could tip you over into losing 1MB of private below the line, so be careful out there.

Re: ESQA is exhausted
So you have some overflow into ECSA from ESQA. So what? Seriously, some overflow is normal and reasonable - but far from universal. Is there any reason to suggest it's actually a problem? (RMF Virtual Storage report - from SMF 78-2 - would help you analyse this.)
