I have a scenario where I am cluttering two different nodes on different LPAR(Horizontal cluttering). I am using WAS 8.5ND and cluttering nodes for active passive scenario. I have MS SQL database Installed on both the node. I am deploying the application on the Cluster and create JDBC provider and Datasources on same. Now my question is can I assign both databases to the single datasource or at the time of database failure I need to change the server name entry in datasource every time ?
