Is the data set (and dfsms) set up for CA_RECLAIM? -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Lizette Koehler Sent: Sunday, August 30, 2020 5:12 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Simple VSAM question on sizing INDEX component
[CAUTION: This Email is from outside the Organization.

When it was set up - the INDEX space was left to default I am wondering if it makes sense to override the Track Allocation and put it in Cylinders. We are noticing a little bit of an increase in run time during reorg. I was wondering if this might be due to the data set having 3.4GB now. This file is EA/EF so it can grow Over 4500 Cylinders on the Data And the index is using tracks 2 pri and 11 sec - size is now 2.4 MB During reorg we offload records to an archive then reload the current data back in. This may be something I cannot improve on, just thought I would see if there are any insights I am missing. Process: Offload the data to a temp file Archive records older than 2 weeks Del/Def VSAM dataset Reload current records to VSAM dataset This runs daily Thank you Lizette ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
