Playing around with running multiple instances of OFBiz in it's own VM, in
a cloud environment, to the same DB.
I ran across this on the OpenTaps docs:
Service engine job pool:
Modify the file framework/service/config/serviceengine.xml for each of your
instances and edit the thread-pool's send-to-pool and run-from-pool to be
different for each instance. For example:
<thread-pool send-to-pool="opentaps1"> . . . <run-from-pool
name="opentaps1"/></thread-pool>
What is the purpose of this?
You don't need this as long as you don't need to isolate some jobs and want them running only on one of the machines (for
performance or other reasons)
Is this so that jobs originated on each
instance are tracked separately on the DB?
Yes, you can say that
Is there anything else that
needs to be tweaked config-wise so the multiple instances don't collide?
You should not get multiple instances colliding. If you want only one instance
of a job to run at a time I'd recommned to set
semaphore="fail" on the related service
You may also consider unique.instanceId in general.properties, look at this
thread http://markmail.org/message/xhc6nfbzsd5ezscg
And if you want to get confused a bit you might look at
