You need to update the Deployment Manager (WAS ND) with the ND-fixpack AND the AppServer(s) (WAS base - although not realy "base" anymore since they are managed by the DeploymentManager) with the base-fixpack. The PTF is included in fixpack 1 so fixpack 1 should suffice - but if you're fixing your WAS with fixpack 1 already
you should use fixpack 2 as well. IMPORTANT: you first have to update to 5.01 AND then to 5.02 - fixpack 2 only, will not work without fixpack 1.
And now the required steps for in-memory replication:
1) create AppServers, install a application on them and add them to a cluster.
2) create a replication domain (if not already done when creating the cluster). I used the default values although using object-serialisation instead of byte-serialisation might be an option, it needs some extra configuration effort though...
3) create one replication domain entry = replicator (can be done inside configuration of rep. domain) for each AppServer involved in the replication process. IMPORTANT: chose one, unique AppServer and two unique ports for each single entry!
4) Stop AppServers and switch to in-memory replication for each AppServer (Web Container -> Session Management -> Distributed Environment Settings -> Memory to Memory Replication). There choose the appropriate replicator with the correct AppServer asigned in step 3 and set the 'Runtime Mode' to 'client' for most / to 'server' for one dedicated AppServer.
5) For
testing only I would recommend switching the replication method to 'medium' (Distributed Environment Settings -> Custom Tuning Parameters) so the session is replicated after each request to a
JSP /
Servlet.
6) Restart AppServers.
That's all - good luck!
