I used the GUI to perform the upgrade. I finally found something very late last night in the Application Server Admin Guide (10.1.2) of all places that talks about creating windows services. It appears I have to have the SC tool from the Windows Resource Kit! job scheduler sc create OracleJobScheduler<oracle_sid> start= auto binPath= "ORACLE_HOME\bin\extjob.exe <oracle_sid>" For example: sc create OracleJobSchedulerORCL start= auto binPath= "INFRAHOME\bin\extjob.exe <oracle_sid>" Note: oracle_sid should be in upper case Brian S.

No, i don't know how to fix it, sounds like a bug - i would open a TAR. How did you upgraded - via gui or per script ?

On the 10g databases I created as 10g from the start - the service is there and disabled. However on the 9i databases that were upgraded to 10g the service is not present and I can't find documentation anywhere that talks about creating this service.
