DB Connect with SHP - multiple Java bridge processes?

If I'm attempting to provide a bit of redundancy / high availability for my database inputs by installing DB connect in a search head pool (SHP), does that mean I will be running multiple Java bridge processes? If one of my SH is unable to execute a scheduled dbmon-tail search, will one of the others in the pool take up the task?

Yes, multiple java bridge processes will run. If you're running that on the same machine, you have to configure different ports for the java bridge on both instances in $SPLUNK_HOME/etc/system/local/java.conf

[bridge]
port = 4712

It's not recommended/supported to run database inputs on DB Connect on a SHP instance. You should use a separate heavy forwarder for this in that case.

Correct. There are no integrated means to gain redundancy for database inputs. If this is required then I'd recommend using external means, such as a VMware HA for the heavy forwarder.

A separate heavy forwarder doesn't get me my redundancy, though. The point of trying to run DB connect on the members of a SHP is to have multiple hosts available to do the "dbmon-tail" or "dbquery".

What is the suggested best practice for this, if not to use SHP?
