Connect Jira to Postgresql with Pgpool-II

Question

I gotta problem with connecting Jira 6 to Pgpool-II which is responsible for load balancing and replication in Postgresql bases(2 instances).

Pgpool is started on port 9999, I just want to connect to it in this (Jira)installation step but Jira tolds that connection attempt failed....

Answer 1

Well ... check the pgpool logs and your servlet container logs.

I'd also try psql 'host=localhost port=9999 dbname=postgres username=postgres password=whatever'

Most likely the PgPool configuration has issues. If it works from psql, you'd need to check out the server logs to see what's up.

Answer 2

Jira and Confluence have some issues starting up with PGPool -> PostgreSQL IF you have read-only query load balancing turned on in PGPool. Turn it off, then see if you can get Jira to successfully connect several times. Then, turn it back on and catch the errors...either Hibernate, C3P0, and/or PGPool get confused and some queries try to get bounced off the standby that should NOT be routed to the standby. Grab those errors and open a PGPool bug report with them...PGPool should handle Jira and Confluence just fine with load balancing turned on, but it does not (at least not in the versions I've tried).

OR, you could turn load balancing off, startup Jira, then turn load balancing back on. It only impacts Jira on startup, not during normal operation. That'll at least get you going. But definitely report whatever errors you see so the PGPool guys can fix it!
