Cross posted to IBM-MAIN and MVS-OE I recently put some toleration and ERRSYSMOD maint onto my z/OS 1.4 system (moving to 1.6). Since the maint has gone on I have seen an increase in the I/O to an application (PeopleSoft) HFS. I/O rates have increased from 5-10/sec to 80-100/sec with no obvious reason. I do not see an increase to other volumes. The HFS is on a volume by itself so I know the activity is strictly related to the HFS. I poured over all the APARs I installed and nothing obvious popped up.
I was thinking of starting up an IO/CCW trace to identify exactly what files are being hit (if I can't think of any other way to isolate the activity). Q1. Anyone have an idea as to why the increase? Q2. Is there any way to get a map of the location of the various files/directories within an HFS? Thanks all!
