Troubleshooting
Problem
Your joblog indicates the failure is in RACF processing. CICS Transaction Server for z/OS (CICS TS) is doing RACF checking to see if a data set with FCT "YOURNAME" can be opened with a particular access. The joblog contains a IRR401I messages that coincides with the CICS trace table. After the S878, things cascaded, multiple dumps are taken and eventually the region abends with a S80A-10.
Cause
The problem was due to IAM vendor code from Innovation Data Processing. IAM stated that there were 60+ empty VSAM files. When they are empty, an attempt is made to open them, the open activity acquires storage below the 16MB line, as opposed to when they contain at least one record. The same storage is acquired above the 16MB line.
Diagnosing The Problem
From the Dump of the abendS878, it appears that you are short on storage below the line. It is not RACF, it appears to be IAM that has tied up 2M of storage below the line. You can see the following in your VSMDATA Summary with IPCS command VERBX VSMDATA 'NOG,SUM':
LOCAL SUBPOOL USAGE SUMMARY

You go to that SUBPOOL 0 Key 8 Storage above and you can see a pattern of the following:

DQE: Addr 00754000 Size 4000
DQE: Addr 00758000 Size 1000
DQE: Addr 00759000 Size 4000
If you look at the SYSTRACE to see the Getmain for the Last piece of Storage, you will find the following:
02 010A 007E3B40 SVC 78 078D0000 80565DE2 00000000 00004000 00000000

Find address 80565DE2 in the dump and see the following:

Resolving The Problem
Prime your VSAM files (add at least one record to the files) before you define them to CICS. Contact IAM Support if you need further assistance.
