| ERROR | WARNING: skipping archived log compromises recoverability |
| CAUSE | SKIP INACCESSIBLE option resulted in skipping archived logs during BACKUP. If the archived log has in fact been lost and there is no backup, then the database is no longer recoverable across the point in time covered by the archived log. This may occur because archived log was removed by an outside utility without updating the repository. |
| ACTION | If the archived log has been removed with an outside utility and the archived log has already been backed up, then you can synchronize the repository by running CROSSCHECK ARCHIVELOG ALL. If the archived log has not been previously backed up, then you should take a full backup of the database and archived logs to preserve recoverability. Previous backups are not fully recoverable. |
