OPSMVS - OPS R 12.0 SOF server startup error:
06.40.02 STC62613 OPS5974I Configuration discovery complete
06.40.03 STC62613 IEA995I SYMPTOM DUMP OUTPUT 520
520 USER COMPLETION CODE=4088 REASON CODE=000003EC
Depending on how many devices are in the IO Config during SOF discovery processing, the installation may see this error on startup.
The 4088 is a storage contraint. If installation is using system default for your REGION size specified in JES2 init deck...you may need to hardcode a region parm on SOF started task JCL. If you have an extrememly large number of devices in your I/O config, add a REGION= parm on the SOF server JCL to 8M/16M/32M depending on number of devices to resolve.
