18.5 Backing up and restoring the database
NNMi provides the nnmbackupembdb.ovpl and nnmrestoreembdb.ovpl commands to back up and restore the NNMi database only. This functionality is useful for creating a snapshot of the data as you experiment with NNMi configuration settings.
The nnmbackupembdb.ovpl command performs online backups only. At a minimum, the nmsdbmgr service must be running.
- Tip
-
Run the nnmresetembdb.ovpl command before restoring data to the database. This command ensures that the database does not contain any errors, thus eliminating the possibility of encountering database constraint violations. For details about running this database reset command, see the nnmresetembdb.ovpl Reference Page.
