When processing a native VSAM file, CA-IDMS is encountering this abend:-
01.00: 00 IDMS DC205006 V1 T1234 NVSAM ERR - PROGNAME FUNC = 18 FDBK = 000 R15 = 08 NVST = 08 R0 = 000 NVERR = 001
01.00: 00 IDMS DC205006 V1 T1234 DDN = VSAMFILE AREA = VSAMSEG.VSAMAREA SET
The operating system 31-bit storage available to the address space has been exhausted.
CA-IDMS, any supported release with native VSAM files defined.
If the CA IDMS CV startup JCL does not already specify REGION=0M, then change it so that it does – this will cause the CV to get as much 31-bit storage as it can.
If it is already using REGION=0M, then you need to reduce the size of any of the other database buffers, either VSAM or non-VSAM in order to free up some storage.
Note that VSAM database buffers cannot be adjusted dynamically – they must be changed permanently in the DMCL - followed by refreshing the DMCL or cycling the CV.
Non-VSAM database buffers can be adjusted dynamically with DCMT commands. Remember to make any dynamic changes permanent by making the same change in the DMCL as well.
