Scaling

[David Hornsby <hornsbydm2@xxxxxxxxx>]

My SMB database is currently running on a HP-UX box running in a master - slave slonyI cluster to create a hot spare database. Recently the server has be getting hammered and we are consistently hitting our max db connections. We have our web CMS and our web apps, our desktop client apps, and a couple application servers running off of this database server and it is crumbling under the stress. Currently we have been doing table partitioning and table archiving to trim the fat off of the indexing processes etc.

My project at hand is to upgrade this configuration to a linux cluster of servers, 2 - 3. The ideal solution is to just do load balancing through DNS requests and have 2 servers in a multi master configuration. So far we have not had any hardware issues on our current set up ( knock on wood). So in doing this I am not immediately looking for a hot spare set up. But in the future am looking at setting up a VPN tunnel to an offsite server and sending WAL updates to that.

Any and all comments are truly appreciated as well as any nudges in various directions.

David.
