CA SymDump Batch is initialized at IPL time and remains dormant until a dump is requested as the result of an abend. CA Symdump Batch then gets invoked by the operating system dump SVC and reports on every abend generating a CA SymDump Batch abend report.
CA SymDump Batch by default suppresses the standard IBM system dump. Sometimes a system dump is required to ship to IBM or a vendor for diagnostic purposes. To suppress the CA Symdump batch dump capture add the CAOESTOP DD JCL statement to the abending job step.
