• Message class: CNV_IUUC_REPL_TS - Messages for troubleshooting functions

• Message number: 009

• Message text: Number of DTL_MT_DATA_LOAD jobs is not equal to the no. of logical locks

What causes this issue?

There is a difference between the number of logical lock entries and the
number of replication processes that are currently running.

System Response

This is a potential error situation. If a replication process cancels
without removing the corresponding logical locks, further replication
processes may be unable to run properly.

How to fix this error?

Check the logical locks for object DMC_JOB by using the
<DS:TRAN.SM12>Lock Overview</>. They must correspond 1:1 to the current
replication jobs that are running (you can check the jobs that are
running by using the <DS:TRAN.SM37>Job Overview</> transaction.
If there are more locks than jobs, or vice versa, stop all the
replication jobs and then delete any lock manually that might still
exist before restarting the replication jobs.

Procedure for System Administrators

Logical locks for object DMC_JOB obtained from function module
ENQUE_READ2.

  Job Failures: Some of the DTL_MT_DATA_LOAD jobs may have failed or been terminated unexpectedly, leading to a discrepancy in the expected versus actual job count.
  Concurrency Issues: If multiple processes are trying to access the
