# Database Disaster Recovery

If the directory server and MAS system databases are badly out of sync and the detained operations list is too large to manage, you can use the "Reset IDS info" command. This command deletes all the IDS metadata and removes all the links between the directory service data and the MAS user data. For example, if you accidently restored an old database to the directory server, the databases could be badly out of sync.

If at any time you have to rebuild the directory server database to recover from a serious failure, you must run this command to start the synchronization process again.

Caution: The following procedure deletes lDS metadata from the MAS system

2. On the next synchronization interval the system performs a full synchronization and creates new metadata and user mappings.
