This Knowledge Document explains why the following messages are issued and what actions need to be taken:
CACM191E SUB STATUS UNKNOWN JOB jobname jobno schedname SYS id XCF FLAGS ffffffff.
CACM192I UNABLE TO SUB JOB jobname jobno schedname SYS id XCF FLAGS ffffffff, RETRYING.
These messages may be issued in a MCPU=YES environment with SUBDIST=YES option. This option allows the master copy of Scheduler to send a submission request to other Scheduler systems.
CACM191E is issued when Scheduler cannot tell if the submission request was received by the target system. Scheduler will mark the job UNKNOWN. If the target system does submit the job, then the job will be marked SUBMITTED and tracked normally. If the target system does not submit the job then manual intervention will be necessary (use the SUBMIT command).
CACM192I is issued when Scheduler believes the target system did not receive the submission request. The submission request will be retained until it can be processed by copy of Scheduler.
