When running an EARL job to create reports using the TMETPUSE EARL source, the follow types of errors were generated:
EARL ABENDED U3000 IN PROGRAM UNKWN1 AT OFFSET +008CE6.
And multiple errors such as the following were also appearing in the output:
11:49:48 +TMSEARL14 - *** INVALID DSNB CHAIN ***
11:49:48 +TMSEARL15 - VOLUME/FILSEQ --->NCL691-00068 NOT ONE GREATER
11:49:48 + THAN PREVIOUS --->NBO701-00001
The TMSPTRS job was run, but no errors were found.
Release : 14.0
The EARL job was NOT using the current/active TMC to report against.
The U3000 EARL abend was caused by having the batch job running for the TMETPUSE EARL report using a backup copy of the TMC instead of the ACTIVE TMC. The TMETPUSE EARL uses TYPRUN=R_CHAINED which requires that the TAPEDB parameter reference the active TMC. The current/active TMC in use can be determined by issuing the command TMS STATUS.
Additional information can be found here (see the info found under the description for CHAINED).
