To eliminate potential java class or system resource conflicts, IBM Cognos 8 must be run in a Java Virtual Machine (JVM) instance isolated from other existing applications. This ensures that IBM Cognos 8 does not affect any existing customer applications. When possible, IBM Cognos 8 must be installed in a JVM instance that is separate from the application server admin processes to isolate both IBM Cognos 8 and the administrative functions of the application server.
An isolated JVM instance can be established by creating one of the following:
a separate managed server in BEA WebLogic
a separate server instance in IBM WebSphere
a separate OC4J instance in Oracle 10g Application Server
a separate server instance for Red Hat JBoss
a separate Java instance for SAP NetWeaver
a separate domain for Sun Java Systems Application Server
If you are using the IBM Cognos Servlet Gateway, it must be run in an instance that is separate from IBM Cognos 8.
