19573, 00000, "cannot obtain %s enqueue for datafile %s"
// *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.
// *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.
应该是数据文件处于online的状态下引起的。 |
