We had a stand alone MWS 7.1.1 server that had several fixes applied, and it was eventually upgraded to 7.1.2. Now I want to add another MWS 7.1.2 node to the same db (oracle) to make a MWS 7.1.2 cluster. This cluster also has a Cisco load balancer in front with “sticky” sessions. I’ve read the documentation and had success creating the second node (according to the Cluster Status screen on server 1, there is a green light for server 2). However, I cannot login to the second node by itself, as it gives me a null pointer exception. Does anyone have any experience with troubleshooting MWS 7.1.2 clustering or moving a custom application from MWS non-cluster to MWS cluster without starting over with a clean install for both servers (nodes).
please be aware
usually a load balancers is used together with an IS cluster, but this is not necessary. You should als obe able to adress all IS in a cluster directly if you adress their real host and port.
You don’t get a cluster by just pointing a second IS to the same database. Did you follow the Integration_Server_Clustering_Guide.pdf and do you see the server in the section Cluster Hosts under Settings - Clustering? I’m asking because the cluster status is not indicated by a green ball and you just mentioned poiting the IS to the same database for clsutering.
