Oracle Database Errors or Warnings from Error ORA-01640 to ORA-01650

SQLServerF1

 

ORA-01640: cannot make tablespace read-only with changes by in-doubt transactions
Cause: An attempt was made to alter a tablespace read-only while there were changes in the tablespace made by in-doubt distributed transactions. The in-doubt transactions must commit or rollback to ensure that there is no undo for a tablespace before it can be made read-only.
Action: Any in-doubt transactions that made changes to the tablespace must be resolved.
ORA-01641: tablespace ‘string’ is not online – cannot add data file
Cause: Attempting to add a datafile to a tablespace that has been set to read-only or offline.
Action: Make the tablespace online and read write then add the datafile.
ORA-01642: begin backup not needed for read-only tablespace ‘string’
Cause: Attempting to begin or end a backup for a tablespace that has been set to read-only.
Action: Take the backup without any begin or end commands. The files are not being modified so the backup will be consistent.

ORA-01643: system tablespace can not be made read-only
Cause: Attempting to set the system tablespace to read-only. The system tablespace must remain read write for database operation.
Action: Leave system tablespace read write.
ORA-01644: tablespace ‘string’ is already read-only
Cause: Attempting to make tablespace read-only that is already read-only.
Action: Leave tablespace read-only, or make read write then make read-only again.
ORA-01645: previous attempt to make read write is half complete
Cause: A failure while making the tablespace read write left it read only, but the checkpoint was advanced. The tablespace will not be useable after a resetlogs if its files are offline.
Action: Repeat the command to make the tablespace read write.

ORA-01646: tablespace ‘string’ is not read-only – cannot make read write
Cause: Attempting to make a tablespace read write that is not read-only. It may be either online or offline.
Action: Leave tablespace read write.
ORA-01647: tablespace ‘string’ is read-only, cannot allocate space in it
Cause: Tried to allocate space in a read-only tablespace
Action: Create the object in another tablespace
ORA-01648: log string is the current log of disabled instance string (thread string)
Cause: An attempt to enable the thread failed after it was half completed. This log was left as the current log even though the thread is still disabled. Since a log switch cannot be done until the thread is enabled, the log can not be cleared or archived.
Action: Complete the thread enable by issuing the enable command again.
ORA-01649: operation not allowed with a backup control file
Cause: An attempt is being made to perform a command that does not make sense when the control file is a restored backup.
Action: Wait until after the database has been opened and try again.
ORA-01650: unable to extend rollback segment string by string in tablespace string
Cause: Failed to allocate an extent of the required number of blocks for a rollback segment in the tablespace.
Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more files to the tablespace indicated.

Oracle Database Errors or Warnings from Error ORA-01541 to ORA-01545

SQLServerF1

 

ORA-01541: system tablespace cannot be brought offline; shut down if necessary
Cause: Tried to bring system tablespace offline
Action: Shutdown if necessary to do recovery
ORA-01542: tablespace ‘string’ is offline, cannot allocate space in it
Cause: Tried to allocate space in an offline tablespace
Action: Bring the tablespace online or create the object in other tablespace
ORA-01543: tablespace ‘string’ already exists

Cause: Tried to create a tablespace which already exists
Action: Use a different name for the new tablespace
ORA-01544: cannot drop system rollback segment
Cause: Tried to drop system rollback segment
Action: None
ORA-01545: rollback segment ‘string’ specified not available

Cause: Either: 1) An attempt was made to bring a rollback segment online that is unavailable during startup; for example, the rollback segment is in an offline tablespace. 2) An attempt was made to bring a rollback segment online that is already online. This is because the rollback segment is specified twice in the ROLLBACK_SEGMENTS parameter in the initialization parameter file or the rollback segment is already online by another instance. 3) An attempt was made to drop a rollback segment that is currently online. 4) An attempt was made to alter a rollback segment that is currently online to use unlimited extents. 5) An attempt was made to online a rollback segment that is corrupted. This is because the rollback is specified in _corrupted_rollback_segments parameter in initialization parameter file.
Action: Either: 1) Make the rollback segment available; for example, bring an offline tablespace online. 2) Remove the name from the ROLLBACK_SEGMENTS parameter if the name is a duplicate or if another instance has already acquired the rollback segment. 3) Bring the rollback segment offline first. This may involve waiting for the active transactions to finish, or, if the rollback segment needs recovery, discover which errors are holding up the rolling back of the transactions and take appropriate actions. 4) Same as 3). 5) Remove the name from the _corrupted_rollback_segments parameter.
