diagnostic material, an entry in SYS1.LOGREC and a DB2 SVC dump is requested. These must be examined
to determine the task and resource manager which made the illegal
request.
 Collect the following diagnostic items:Console output from the system on which the job was run, and a listing of the
SYSLOG data set for the period of time that spans the failure. 
Dynamic dump, taken to SYS1.DUMPxx data set, by DB2 (04E

IFCEREP1.
