Reports aren't executing properly in Clustered environment

Issue: All Reports were executing properly, but after migrating to a new environment i.e copied database from Prod to dev few reports are executing and few reports gives weird errors. The same issue can happen after Maximo upgrade

Version: Maximo 7.1 or higher

Solution: In a clustered environment, initially, you must generate the request page xml for each individual instance or all JVMs have to be restarted after generation of request pages in one JVM.
