Use this page to specify the feature level for a schema repository
in a selected connection. Upgrading the feature level defines the features
enabled by the schema repository.
Upgrading the feature level
If you are upgrading
from feature level 3, the Maintenance Tool also upgrades the metaschema version
of the schema repository. It is critical to back up the databases before performing
the upgrade. You may not be able to restore the databases to an earlier state.
The
following fields appear:
- New Schema Repository Properties
- Choose the Feature Level for the schema repository.
The default feature level is the latest level available. If you are unsure
about which features this level will enable, see the Determine feature level topic.
- If you have created a new, empty database for the feature level upgrade,
specify the properties in the New Schema Repository area.
For information on creating empty vendor database containers, see the chapter,
Configuring Vendor Databases in the IBM Rational ClearQuest and ClearQuest
MultiSite Installation and Upgrade Guide. Also, keep in mind that when
you specify database parameters, case sensitivity may apply to the vendor
database you choose.
- If you perform an in-place upgrade, provide the properties of the Source
Schema Repository in the New Schema Repository area.
With an in-place upgrade, the new version of the database is written back
onto the original database file, replacing the previous database structure.
Note: You
cannot perform an in-place upgrade using the Maintenance Tool if you are upgrading
from feature level 3.
The Maintenance Tool displays the following message if you
are performing an in-place upgrade:
- Be sure you have current backups of the databases before you continue.
Any client that has not been upgraded to the current version of Rational ClearQuest
cannot access the upgraded database. Do you want to continue?
- Click Yes to continue or No to
cancel the upgrade.
