Applying a Schema
NOTE: An applied schema cannot be reverted. The only way to revert to an old schema
is through the backup and restore mechanism described in “Archiving and Restoring”
on page 309. We recommend that you perform a backup of the GUI Server and the Device
Servers before applying a new schema.
To apply a new schema, follow these steps:
1.
In the Administer panel, select Schema Information .
The Schema Information screen appears in the main display area. It shows
information about the schema that is currently staged (the most recently downloaded
schema) and the schema that is currently active. Details for each version include a
version number, the date of last update, a brief description of what changed in that
version, and a list of files affected by the change. Compare the version numbers to
tell whether the staged schema is more recent than the currently running schema.
Check the information about the schema to determine whether you want to update
to the new schema; it might contain only changes that do not apply to your devices.
Also, if a more recent schema is staged, then the Apply Schema button is active.
2.
Click Apply Schema to activate the latest staged schema.
The NSM UI warns that the GUI Server and Device Server will restart as a result of
this action, and that all UI users will be logged out.
3.
Click Yes to proceed with the upgrade.
The GUI Server and Device Server restart. When you log on in the restarted UI, the
new schema will be active.
The Job Information screen provides information about the progress of the job, and
informs you if any device family is disabled in the new schema.
