I am implementing a singleton MDB class. But in my environment the singleton does not works because the two nodes are elected as singleton provider.
Configuration 2 nodes domain mode for both nodes. master-slave, the way to stablish communication between the two nodes 1 group with full-ha profile 2 server or application, one in master, one in slave. Each application belong to the same group. It is necessary that in that configuration, only one of the application appear elected as singleton provider.
Note: Working in local or with one node, the ClusteredSingleton works.
Please, if someone can help me, I´ll appreciate it.
