Question
Why would I receive message IEA705I reporting an 878-10 abend in my CICS Transaction Server for z/OS (CICS TS) region when using vendor product IAM from Innovation Data Processing ?
My CICS region went down with the following messages:
IEF170I cics jobname DFHSR0606 cics applid Abend (code 878/AKEX) has been detected.
IEF170I cics jobname DFHME0116 cics applid
(Module:DFHMEME) CICS symptom string for message DFHSR0606 is
PIDS/5655Y0400 LVLS/690 MS/DFHSR0606 RIDS/DFHSRP PTFS/HCI6900
AB/S0878 AB/UAKEX
IEA705I ERROR DURING GETMAIN SYS CODE = 878-10 cics jobname
Answer
Rewiewing the dump with IPCS command verbx vsmdata 'nog summ', it was possible to see thru the local storage data summary that the problem is below the 16MB line:
L O C A L S T O R A G E D A T A S U M M A R Y
**LOCAL STORAGE MAP

** User Region Top has hit bottom of LSQA**
The subpool with significant usage below the line is 230 key 5:
LOCAL SUBPOOL USAGE SUMMARY
TCB/OWNER SP# KEY BELOW ABOVE TOTAL
--------- --- --- ----- ----- -----
9FAC60 230 5 41000 CD000 10E000
Looking at the Data for subpool 230, key 5 for the TCB that reports the storage consumption, it is possible to see lots of areas with size X'1000'.
Examples of DQEs (FQEs sizes vary):
DQE: Addr 00901000 Size 1000
FQE: Addr 00901000 Size 10
DQE: Addr 00939000 Size 1000
FQE: Addr 00939000 Size 1C0
These DQEs have areas with eyecathers CVIOW...INIT and IOBE.
They refer to areas of CVAF Component of DFSMS. The common volume-table-of-contents access facility (CVAF) provides system and user access to VTOCs.
Checking the system trace with IPCS command SYSTRACE TIME(LOCAL) there are many entries showing that CVAF macros were issued:
0000 008A 009FAC60 SVC 8B 00000000_1A1DD042 80234C88 5D461389 008C4870 Cvaf
0000 008A 009FAC60 SVC 8B 00000000_1A1DC636 00000000 00000000 008C4870 Cvaf
In CVPL (CVAF Parameter List) the bit IOAREA=KEEP is on.
The command IPCS WHERE for the above addresses shows that they pertain to Innovation Data Processing vendor IAM product:
ASID(X'008A') 1A1DD042. IAM0001I+1002 IN EXTENDED CSA
ASID(X'008A') 1A1DC636. IAM0001I+05F6 IN EXTENDED CSA
The vendor provided fixes for IAM 9.2:
ZAP-ID# : P-92.0101 for abend S878
ZAP-ID# : P-92.0091 for abend S378
