I am upgrading EBS 11i to 12i, Discoverer 4 to 11. After completing ebs installation and upgrade successfully, I am now working on the Oracle Fusion piece of the upgrade.
I have installed
2. Repository Creation Utility - RCU (schema)
3. Weblogic - WLS 10.3.6
4. Oracle Fusion - Discoverer 11g Release 1 Patchset 1 22.214.171.124.0 PFRD
5. Oracle Portal, Forms, Reports and Discoverer 11g Patchset 126.96.36.199.0 - Patchset 13517084
6. Executed config.sh and it failed with but continued.
During the Configuration of Oracle Fusion with config.sh there was failure at with "fails at creating data sources" and accidentally proceeded and all seem to go well until after shutting down the servers when Weblogic Managed Server is unable to start.
The start log indicated: "weblogic.store.PersistentStoreFatalException: [Store:280105]The persistent file store "_WLS_WLS_DISCO" cannot open file _WLS_WLS_DISCO000000.DAT." and I have been unable to find a solution for this error?
If re-installation is my only option, then what are the steps to uninstall, and which components do I have to uninstall given that I had upgraded all the schemas involved?
You can always change the JDBC datasources in the Weblogic admin console . but have you recorded what is the specific error you got during the datasources creation .
I prefer...create a new user , give him sysdba privillages . Start RCU and create the DEV_DISCOVERER , DEV_DISCOVERER_PS schemas (prefix is your choice)
The Admin server will start . so go to admin console .
click services -> Data Sources
Check the data sources you have . edit each datasource and update the connection pool information .
after this you can start the Managed server WLS_DISCO
i believe this will solve this .........
if you still get issue again . you can try the link Using the WebLogic Persistent Store
