TruCluster and CAA

I have my 2 node cluster now working with SAP and Oracle and have tested
that failing from one node to the other works.

I have the listener start and then oracle and sap start in the start up
script.

There is nothing else running on the systems. If I do something simple such
as start a SAP GUI then caa fails the applications over to the other node.
I suspected that this is a balance problem, as soon as there is a load on
the one system the system fails to the other but I could be wrong. Can
anyone offer advice, please?

I have attached the caa profile.

Also failing back gives me problems when I restart the first failed node. I
suspect this is because the listener is left running on the second node and
the database cannot start. Can I stop the applications starting up again on
the failed node once it has recovered?
