The following is the ORA-19573 error message, you can learn the cause and solution of the Oracle database error.

ORA-19573 cannot obtain string enqueue for datafile string

Cause: The file access enqueue could not be obtained for a file specified in a backup, copy or restore operation. If the enqueue type shown is SHARED, then the file is the input file for a backup or copy. If the type is EXCLUSIVE, then the file is the output file for a datafile copy or restore which is attempting to overwrite the currently active version of that file. In this case, the file must be offline or the database must be closed. If the type is read-only, then you are attempting to back up or copy this file while the database is in NOARCHIVELOG mode.

Solution: Wait until the conflicting operation is complete, then retry the copy or backup. If the database is in NOARCHIVELOG mode, then all files being backed up must be closed cleanly.
