Unable to change maximum number of parallel job runs

[Alex McNeilly]

In our current Rundeck installation (version 2.0.3) we are only able to run ten jobs in parallel across all projects which is not always enough.

According to the information on "Scaling Rundeck" we need to change the maximum threadCount value for Quartz scheduler as follows :

Quartz job threadCount

The maximum number of threads used by Rundeck for concurrent jobs is set in the quartz.properties file. By default, this is set to 10.

• Launcher install: $RDECK_BASE/server/exp/webapp/WEB-INF/classes/quartz.properties

To change the maximum threadCount modify this file and alter the line:

org.quartz.threadPool.threadCount = 20

Set the threadCount value to the max number of threads you want to run concurrently.

The file quartz.properties is empty. We can add the line org.quartz.threadPool.threadCount = 20. However, when we restart Rundeck the file is overwritten and returns to being a blank file again. We cannot seem to increase the maximum number of threads using this method.

Tried on a VM with the latest version (2.1.2). Same result. Any changes made to $RDECK_BASE/server/exp/webapp/WEB-INF/classes/quartz.properties are lost on restart.

It seems this may depend on the installation method. We were not able to get this to work using the self contained jar launcher.

However, installing using the deb on an Ubuntu VM allowed us to modify quartz.properties and have the change stick after a service restart. The (future) prod server is not debian-based so be trying a few other install methods.

Sounds like a bug in the launcher packaging. Might be the quartz.properties template or the config generation is not working.
