I HAVE LOADED ORACLE 8i ON WINDOWS XP. IT HAD LOADED SUCCESSFULLY AND
I HAD WORKED ON IT. BUT ON NEXT REBOOT WINDOWS IS NOT ABLE TO START
THE SERVICE CALLED OracleServiceORCL. WHEN I TRY TO START IT AGAIN IT
ENDS WITH AN ERROR:-
Could not start the OracleServiceORCL service on Local Computer
Error 1053: The service did not respond to the start or control
request in a timely fashion
Look in task manager and see if oracle.exe is running. Windows might have initialized thread space for Oracle but not started the instance into the thread space, which of course would preclude Oracle from opening a database. If oracle.exe is running, then go to a command prompt and try starting the database manually. This will isolate where the problem is.
connect sys as sysdba
If startup fails because already started, then try to alter database mount and alter database open.
On Win2K and XP you might try editing $OH/network/admin/sqlnet.ora and setting parameter sqlnet.authentication_services=(NONE) This is related to a bug fixed in 81721 and higher.
