3445809 - Open transaction in outbound queue for multiple replication servers - SRS

Symptom

  • An open transaction that appeared in OBQ at RRS after scheduled regular weekend server restarts.
  • It was observed that new transactions were being replicated but the queue kept increasing due to the open transation.
  • Confirmed that the same transaction was replicated from the same PRS to 3 other targets via routes to three other RRSs without any problems.
  • Only one RRS had the issue.
  • This problem happened multiple times, but it is not reproducible.
  • The hosts which host Replication Servers and RSSD servers are scheduled regularly to reboot.
  • The DBAs have no control over the host reboot sequence.
  • Though only closed transactions are distributed from PRS to RRS. The commitment of this transaction must have been missed.
  • Would like to know the root cause so it can be prevented from happening again.
