Replication issue

From
Sonam Sharma
Date:
I have setup db replication. And added below parameter in jdbc file . The connection is failing and it's throwing error like db doesn't exist on secondary server. 

jdbc:postgresql://<primaryhost>:50001,172.29.195.216:50001/crowd?targetServerType=master&reWriteBatchedInserts=true

 

.PSQLException: FATAL: database ",172.29.195.216:50001/crowd" does not exist


Can someone help on this issue?

Set up replication using what?

The URL above does not look correct to me. Pretty sure the ',' does not 
belong there.

This was probably intended to be the "connection failover" feature
(https://jdbc.postgresql.org/documentation/head/connect.html).  I'm
wondering if the issue is just that the driver is too old to support
that, but I have no idea when this was introduced in jdbc.

Yes, you are right. It's for connection failover from application end. I have set up db replication using repmgr. Version : 9.5

Can you reach the database crowd at host 172.29.195.216:50001 using psql 
or some other client?
