So today, suddenly on the weblogic server, I found out that the eis/DB list on outbound connection pool is disappear. It’s only showing javax.resource.cci.ConnectionFactory (on Deployment > DBAdapter > Configuration tab > Outbound Connection Pool).
After some discussion with my senior expert, I found out that it happened because the plan.xml was inconsistent. After checked it thorough, it had inconsistent data. Some developers added some connection on dbadapter before, and it’s not success.
So after I deleted the inconsistent component, and after activating the changes, finally the list of outbound connection pool reappeared. Et Voila!
Hope it helps.
