Clustering of Quartz for JBoss ESB

massios Aug 5, 2010 3:59 AM

Some thoughts on Quartz Clustering for JBoss ESB.

1. There are two instances of the Quartz Scheduler

a) The instance used by JBpm.esb node1\deploy\jbpm.esb\jbpm-quartz.properties

b) The instance used by rosetta. (inside jbossesb-rosetta.jar path org/jboss/soa/esb/schedule/quartz.properties)

2. Instructions on how to cluster the Quartz (from quartz).

3. I changed the persistance for jbpm to oracle from h2 and I guess this is fine now.

4. I need to change the persistance for the built in quartz to oracle but I am not sure where to put to updated quartz.properties.

Inside the jar? It is not a very good way to package it.

5. The rosetta properties reads now as follows. This is an answer to an older question I had (https://community.jboss.org/thread/150010)

# Default ESB Quartz Properties file.
#

org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadPriority = 5

org.quartz.jobStore.misfireThreshold = 1

org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

6. There is a worrying JIRA issue from about a year ago

7. Has anyone managed to sucessfully cluster the rosetta quartz scheduler?

I think basically the solution to

is to take the scheduler configuration out of the xml and put it in the database.
