Problem:
Repository can no longer be created. If you use an Oracle or DB2 repository, you see one
 of the following error messages: 

 java.sql.SQLException: ORA-00942: table or view does not exist

 COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] 
 SQL0204N  "EJSADMIN.LOCK_TABLE" is an undefined name. SQLSTATE=42704

 This error occurs because a new property was introduced in Fix Pack 3.



Solution:
This property can be found in the admin.config file located in the bin directory of the WebSphere installation directory. 

Example File Location:c:\WebSphere\AppServer\bin\admin.config
The property name is:com.ibm.ejs.sm.adminServer.dbInitialized=true 

This property will be added when Fix Pack 3 is started for the first time and the WebSphere Application Server repository is created/verified.

Note: If the WebSphere Application Server database is dropped after this property is added to the admin.config file, database exceptions will occur. To rebuild the database, follow these steps: 

1.Stop the WAS Administrative Server if it is running. 
2.Modify the admin.config file and remove the
   com.ibm.ejs.sm.adminServer.dbInitialized=true property 
3.Start the WAS Administrative Server. 

After adding this property to the admin.config file, uninstalling a Fixpack will NOT remove it. You MUST manually delete the property.
