SQLServerF1

ORA-19941: invalid blocksize in cross platform datafile string
Cause: Blocksize in header of datafile copy being converted at target was invalid. Either datafile has not been made read/write with compatibility 10.0 or greater at source database or datafile copy is corrupted.
Action: Make a new datafile copy taken after tablespace has been made read/write with compatibility 10.0 at source database and retry conversion.
ORA-19942: datafile copy string not created with compatibility 10.0 or greater
Cause: The specified datafile copy to be converted at the target was not produced after making the tablespace in read/write mode with compatibility 10.0 or greater at the source database.
Action: Make a new datafile copy taken after tablespace has been made read/write with compatibility 10.0 at source database and retry conversion.
ORA-19943: The current database incarnation changed during backup
Cause: The backup failed because the current database incarnation was changed during the backup. One of the following events caused this incarnation change:
– The database was opened using ALTER DATABASE OPEN RESETLOGS statement.

– RMAN command RESET DATABASE TO INCARNATION was issued.

– If this happened on physical standby database, then redo apply has applied redo data from a new database incarnation.

Action: Re-try the backup.

ORA-19951: cannot modify control file until DBNEWID is completed
Cause: An operation requiring to modify the control file was attempted, but a NID change is in progress.
Action: Wait until NID completes before attempting the operation.
ORA-19952: database should be mounted exclusively
Cause: The database was started in parallel mode. To change the DBID, the database must be mounted exclusively.
Action: Shut down the database and start it in exclusive mode.

Cause: The database was open. To change the DBID, the database must be mounted exclusively.
Action: Shut down the database and mount it in exclusive mode.

Cause: The operation failed because a non-current, non-standby control file was mounted.
Action: Make the control file current and retry.
ORA-19955: only one open thread is allowed to change the DBID
Cause: The operation failed because there were active threads in the database. The most likely cause is that the database crashed the last time it was shut down.
Action: Ensure that all threads are closed before retrying the operation. Start and open the database to perform crash recovery, then shut down with the NORMAL or IMMEDIATE options to close it cleanly. Finally, try running the utility again.
ORA-19956: database should have no offline immediate datafiles

ORA-19958: potential deadlock involving DIAG process
Cause: DIAG requested a control file operation that may lead to a deadlock
Action: Try last operation later when the control file is released
