Using register 6 as the address of the execution block (EB), check that field EBPASCE contains a valid ASCE address. Also determine the recovery module invoking the macro from the information provided by the SYS1.LOGREC entry and the associated SVC dump.
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 and 04F abends).
- Listing of SYS1.LOGREC data set, obtained by executing IFCEREP1.
