JDBC thin connection is not working when one instance of a 2 node RAC Database is shut down.
Listener configuration / behavior has been verified.
-- When Node A has its database instance shutdown or crash, the JDBC connections hang and go into pending status.
WebLogic Server is using the next configuration:
1] Regular data-source
2] Using SCAN on the URL JDBC
3] The minimum number of connection is 1
When the first node in the RAC is stopped, the problem is produced; if the second node is stopped. all works fine.
