To eliminate potential java class or system resource conflicts, Cognos 8 must be run in a Java Virtual Machine (JVM) instance isolated from other existing applications. This ensures that Cognos 8 does not affect any existing customer applications. When possible, Cognos 8 must be installed in a JVM instance that is separate from the application server admin processes to isolate both 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 Web Application Server
If you are using the Cognos Servlet Gateway, it must be run in an instance that is separate from Cognos 8.
