Start using Slave Database

[hichew]

My site has been running on single database server for 2 years.
And I think it's time for me to use "slave database" feature.
How to use it?
Should I copy the database from Master DB to Slave DB first?
Or it will automatically do it after adding the "Slave DB" in the config.php

Thank you

It's not a "vbulletin" feature.

You need to have two database servers setup in a master slave relationship to be able to make use of the system.

but i saw that option in config.php
i know that i need to setup 2nd database server
any instruction "how-to" use that feature?

No, it requires mysql replication, if you have mysql replication properly setup. vBulletin just sends certin queries to master, and others to the slave.
