Our current development middleware stack contains:
WebLogic, WebCenter, WebTier, & OAM all pointing to the same oracle db repository via an IP address (due to hostname resolution issues.) Unfortunately the database server's IP changed and I'm unable to start the weblogic admin console in order to change the database IP.
Task 5 Change the System Data Source
If you use the IP address in the data source definition, change the system data source to use the new IP address for the metadata repository. To do so, you use Oracle WebLogic Server Administration Console:
Excerpt of WebLogic Admin Console startup:
<Aug 27, 2013 3:52:03 PM EDT> <Warning> <JDBC> <BEA-001129> <Received exception while creating connection for pool "mds-CustomPortalDS": IO Error: The Network Adapter could not establish the connection.>
For this particular case, we can simply reinstall the whole stack but would prefer a cleaner resolution.
There seem to be two more problems here. The console is just an application, so I am going to assume
that what you mean is that the WebLogic server itself will not boot up, presumably because some
vital service depends on your datasource, and your datasource can't deploy, because it's config insists
on an initial capacity greater than zero...
So, go to yuor config/jdbc directory, below the main domain directory, and for every datasource
you have, there will be an .xml file there. Edit each file that represents a datasource to the affected
DBMS, and change the driver URL given, to have the correct, new DBMS machine name/IP Address.
Then try rebooting WebLogic and see if you're OK...
