Error description
One of your files has been set to UNENABLED status after an ABEND 0C8/AKEA in modules DFHFCN. Reviewing the regions Joblog you see the following messages: DFHAP0001 An abend (code 0C8/AKEA) has occurred at offset X'00004DF0' in module DFHFCN DFHFC0001 An abend (code ---/ASRA) has occurred at offset X'60EE' in module DFHFCFS Investigation into the 0C8/AKEA shows the failing instruction in DFHCFN at offset x'4DF0', is 5B20 803C (S R2,FCTDSXCP ). Reg2 contains the the SHOWCB NEXCP field. Reg8+3C (7FFFFFFF) field FCTDSXCP, is subtracted from Reg2 (000009C2) which causes the failure. Further review of the Joblog shows this file has been open for a long time. And the number of EXCPs against it are very high. As a result, this causes DFHFCFS to suffer the 0C8 when it attempted to perform the subtract instruction. Additional Symptom(s) Search Keyword(s): FCFS S0C8 0c8 FCN AP0001 FC0001 KIXREVJXD
