After you check in a schema, you can upgrade the user databases
that used an earlier version of it. You do not have to upgrade these databases
immediately, but the changes to the schema are not available until you do.
Before you begin
Upgrading the user database is an irreversible process. Before applying
schema changes, back up the user database. Also, immediately before you apply
schema changes, verify that no users are logged in to the database. The upgrade
operation fails if users are connected to the user database. Users cannot
log in during the upgrade process, but they cannot be disconnected.
About this task
When
a user database is associated with a specific schema version, you can apply
only newer versions of the same schema to that database. You cannot apply
earlier versions or a different schema.
For more information about
databases, see the online help for the Rational® ClearQuest® Administrator.
