Applies to:Oracle Weblogic Server - Version: 10.3.1 to 10.3.4
Information in this document applies to any platform.
- Shutdown managed server.
- Shutdown the database server (DB server).
- Startup managed server.
- DB server is still down.
Result will be :
- managed server started in RUNNING mode.
- data source is accessible in the admin console (deployed).
- from administration console, data source shows "State: RUNNING" and "Enabled: true" => this makes us think monitoring is broken.
- You will see following error in the corresponding server's log:
####<Feb 21, 2011 11:17:46 PM IST> <Warning> <JDBC> <Test> <TestServer1><[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <
> <> <> <1298310466219> <BEA-001129> <Received exception while creating connection for pool "DS1": Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor >
Even if we trigger a connection test (Data Source/Monitoring/Testing), the test fails as expected with ORA-12521, but the monitoring still shows "State: RUNNING" and "Enabled: true" for this Data Source. This is not same as when DB server fails while WebLogic server is running (in which case pool state is automatically changed to "Disabled").
