Well, later I found following error in my dbwr trace file...Originally posted by Sameer
So where is my tempfile.. FILE IS NOT PHISICALLY PRESENT ON THE DISK.... I have renamed it.... as I have said it before.. so logically tempfile displayed by v$tempfile view doesn't PHYSICAL EXIST ON DISK AND ALSO NEW FILE IS NOT PHYSICALLY CREATEDCode:# Recovery is required if any of the datafiles are restored backups, # or if the last shutdown was not normal or immediate. RECOVER DATABASE USING BACKUP CONTROLFILE # Database can now be opened zeroing the online logs. ALTER DATABASE OPEN RESETLOGS; # No tempfile entries found to add. #
Somehow my system could not able to create file physically on disk.. and later when I did big sort operation I got ORA-25153.. I added a tempfile and everything worked well...Code:*** 2002-09-28 19:05:04.000 *** SESSION ID:(2.1) 2002-09-28 19:05:04.000 ORA-01157: cannot identify/lock data file 201 - see DBWR trace file ORA-01110: data file 201: 'C:\ORACLE\ORADATA\ORCL\TEMP01.DBF' ORA-27041: unable to open file OSD-04002: unable to open file O/S-Error: (OS 2) Das System kann die angegebene Datei nicht finden.
