How to reduce the time switch PostgreSQL between these nodes on Veritas Cluster

Hi all,

I have Veritas Cluster configuration for PostgreSQL on Linux. The cluster includes 2 node. I test with node 1 (active) down, the online time of node 2 is very low (value of this time is large). How to config to this online time fast or this time reduce ?

Many thanks,

I have moved this post to the Cluster Server forum.
It got lost in the 'General Veritas' forum.

You can use CFS for share filesystems, This way you can minimize the downtime splitting the infraestructure /  Database or application.

 

I don't remember if the postgresql agent is using IMF, if not you can use the Application agent for better time detection.
