Before you assign
a new schema to a user database, review the
Manage databases topic in the online Help for administering
Rational ClearQuest.
If you want to change the schema that a database uses, you must first
create a new database, move your existing data, and then associate that database
with the new schema.
To create a new user database to prepare for a schema
change:
- Start the Designer.
- In the ClearQuest Schema Repository Explorer view,
right-click on a schema repository and click . The New
Database wizard opens.
- On the Database Name and Vendor page, choose
a Logical Database Name, select a Database
Vendor, and record any Comments about the
database.
- Select a Database Type, either Production
Database or Test Database.
- Click Next.
- The options on the next page of the wizard will vary depending
on the database vendor you chose. Complete the information required for your
chosen vendor and then click Next.
- On the Database Timeout Option page, select
the Timeout and Poll Interval for
the new database, and then click Next.
- On the Initial Schema Revision page, select
the schema version that you want to associate with the new database.
- Click Finish.
After you create the new database, you must export the data from
your current user database and import it into the new database. For instructions,
see
Importing and exporting data.
