Re: Subscription stuck at initialize state

The only statement I see on the target DB log is
"logical replication apply worker for subscription ""sub_omx_archive_tci"" has started",,,,,,,,,""

I don't see the logical replication table synchronization worker started for any of the tables in this subscription as I see in the other one.

Is there anything in particular that I should be looking for in the log files?

Hi Abishek,

Have you checked the subscriber and publisher database log files to see if there is a problem blocking the subscription? For example, a subscribed table missing a column that exists in the publisher.

Cheers,

Steve

I have 2 sets of publication/subscription between my 2 DBs.

One of them is working fine and the other one is stuck at initializing state for all the tables.

I have dropped the subscription, recreated and refreshed it many times, but it won't move from the initializing phase.

Any suggestions on how to start copying the data again, other than dropping the publication and re-creating it?
