Cache Configuration
on PRPC6.2 ENV do we need to maintain separate cache directory (prtemp) for individual jvm which are in same UNIX BOX HOST?.
I believe common cache directory for all jvm's on unix box will reduce the DB calls for generating cache. And also reduce the load on system pulse/system cleaner to synch cache and delete the stale cache things.
But would like to understand the conflicts to do this. Please provide your data points for pros and cons..

using hazel cast we are trying to clone the reusable ootb object instances from memory between nodes. so why we explicitely need prtemp between nodes? why we need to generate assemble classes / java classes/ libraries ,etc specific to jvm ?
each jvm needs to have its own pega temp directory otherwise there will be some unforeseen behavior. This is explicitly in the latest pega 7 installation guide, e.g., https://pdn.pega.com/documents/pega-72-platform-installation-guide-tomcat-and-oracle
Setting multiple nodes to the same pega temp directory is not an option. You may not see issues right away but we have seen some weird behavior due to this setup.
