Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB and ACCOUNTS_PDB,
both of which use the CDB tablespace. The temp file is called temp01.tmp.
A user issues a query on a table on one of the PDBs and receives the following error:
ERROR at line 1:
ORA-01565: error in identifying file ‘/u01/app/oracle/oradata/CDB1/temp01.tmp’
ORA-27037: unable to obtain file status
Identify two ways to rectify the error.
Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.
Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the
Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring
the temporary tablespace online.
Shutdown the database instance, restore and recover the temp file from the backup, and then open the
database with RESETLOGS.
Shut down the database instance and then restart the CDB and PDBs.
* Because temp files cannot be backed up and because no redo is ever generated for them, RMAN never
restores or recovers temp files. RMAN does track the names of temp files, but only so that it can automatically
re-create them when needed.
* If you use RMAN in a Data Guard environment, then RMAN transparently converts primary control files to
standby control files and vice versa. RMAN automatically updates file names for data files, online redo logs,
standby redo logs, and temp files when you issue RESTORE and RECOVER.
