ORA-19573
cannot obtain enqueue enqueue for data file data_file
- enqueue: The enqueue name.
- data_file: The data file to copy or backup.
Cause
The file access enqueue cannot 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 data file copy or restore that 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.
Action
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.
