WebSphere Liberty Configuration deployment question.
Hello! I'm looking to deploy a Pega application to WAS Liberty. For Liberty, you need to setup a jvm.options file. In that file, you specify the -DNodeType, and -Dindex.directory, -Didentification.nodeid, etc. On a single JVM and single server, that is easy to do.
My question is - how do you setup the jvm.options file when you have multiple jvms on a server (or across multiple servers)? I need to have the jvms horizontally and vertically clustered. The node types will vary and not every jvm is going to have a search directory. Each JVM needs its own nodeid so you can identify them on the PDC as hash values not not helpful.
I'm coming from a WebSphere 8.5.5 background where you can specify the JVM parameters in the WAS Console. This is not so with Liberty, so perhaps there is a different option(s) to set this up.
Thanks!
Fred.

You might be better off consulting IBM on this. The implementation guide below speaks to the jvm.options file you mention. Anything beyond that would depend on Liberty expertise.

Thanks Paul. We did consult with IBM. The jvm.options file does not support variable expansion. IBM indicated that we could use the JVM_ARGS environment variables to pass additional settings to the JVM and rely on shell to do the variable expansion.
For example:
export NODE_TYPE=WebUser
export JVM_ARGS="-dmyProperty=${NODE_TYPE}/foo"
Thanks!
