Frequently asked questions about memory-to-memory session replication in WebSphere Application Server 5.0
 Technote (troubleshooting)
 
Problem(Abstract)

  1. Is memory-to-memory session replication for session persistence available in WebSphere® Application Server v5.0 (base)?

  2. Does memory-to-memory session replication provide all the performance related options (such as time base write)?

  3. Is the WebSphere Embedded messaging used for memory-to-memory session replication?


 
Resolving the problem
  1. Is memory-to-memory session replication for session persistence available in WebSphere Application Server v5.0 (base)?

    A. No. Memory-to-memory session replication is a WebSphere Application Server Network Deployment option. With WebSphere Application Server v5.0(base), use database persistence to persist your sessions.

  2. Does memory-to-memory session replication provide all the performance related options (such as time base write)?

    A. Yes. Memory-to-memory session replication provides all the performance related options such as time based write or write only when changes are made.

  3. 3. Is the WebSphere Embedded messaging used for memory-to-memory session replication?

    A. No. If you install WebSphere Application Server (base) and Network Deployment without selecting WebSphere Embedded Messaging, the memory-to-memory session replication still works. The memory-to-memory session replication uses an Internal Messaging system and it does not have any dependencies on the WebSphere Embedded JMS Provider.
