Ora-01157 Ora-01110 Solution
DBWR trace file ORA-01110: data file 5: 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\EXAMPLE01.DBF' How do I fix this ORA-01157 error? Answer: First, the Oracle docs note this on the ORA-01157 error: ORA-01157: cannot identify/lock data file string - see DBWR trace file Cause: The background process was either unable to find one of the data files or failed to lock it because the file was already in ora-01110: data file use. The database will prohibit access to this file but other files will be unaffected. However the first instance to open the database will need to access all online data files. Accompanying error from the operating system describes why the file could not be identified. Action: Have operating system make file available to database. Then either open the database or do ALTER SYSTEM CHECK DATAFILES.
As we see, the ORA-01157 is caused by a locking issue with the database writer (DBWR) background process. During a recovery, this can be caused by a unopened data files (i.e. database mounted but not open), a missing file, a permission problem in the file (e.g. no write permissions 770 on the files owned by Oracle). If the background process is unable to reach a data file, or is unable to lock it because it is in use , ORA-01157 is thrown because the database does not allow access. The other files will not be affected, but it is important to know that opening the database using the first instance will need to use online data files. thcannot identify/lock data file If this is your first visit, be sure to check out the FAQ by clicking the link
