How to create per instance jvm.config files for multi-instance ColdFusion Cluster ?

[PradeepManda]

So when we have created our coldfusion 9 instance on solaris all the files and settings of the master instance are copied except the jvm.config file. This means that any changes made here are used for all instances of ColdFusion on that Node.  Now I want to play with memory settings for fine tuning of Application performance and I want to do it on one single instance. I want to know the process of creating individual jvm.config files for each instance.

Thanks

Hello Pradeep,

Thank you for your post. Please refer to http://helpx.adobe.com/legacy/kb/jrun-4-0-configuring-individual.html for Configuring individual JVM settings for each JRun Server

Thanks Anit,  I did whatever is posted in the KB Article. Now I get this below error #

Are you getting the error message, while starting the instance?

Do you have the servers.xml available at /data/www/appserver/jrun/lib/. If yes, can you share the content for the same?

one more thing, when we revert back to default jvm.config, everything works fine.

Have you installed the JRun server as a Windows service? If yes, then you will first need to remove it and then reinstall it using the below command line syntax.

Install the service using the following command:

jrunsvc -install jrun_server service-name service-display service-description

-config custom_jvm.config
