In Weblogic 10.3.3.0 with OSB or BPM - Managed Server is the test button in DBAdapter not enabled.
I have configured the Connection Pool (test passed), but after registering with DBAdapater and update it is the Test button not enabled.The (german) message is like *"This Connection Pool can not be tested"*.
I have compared the configuration to the old one (from 10.3.2) and see only one difference: the platformClassName ist now "org.eclipse.persistence.platform.database.Oracle10Platform", former it was: "oracle.toplink.platform.database.Oracle10Platform". I have changed it later to this old platformClassName but without success.
The message "This Connection Pool can not be tested" means that the ManagedConnectionFactory class of adapter does not implement ValidatingManagedConnectionFactory therefore it is impossible to do test.
You may need to post to DBAdapter's forum to get the answer. This forum is about WebLogic Container itself.
