Vendor database configuration

Rational® ClearQuest® schema repositories and user databases are types of databases that are physically managed by a database management system. Depending on your platform, these systems might include Microsoft® Access, Microsoft SQL Server, Oracle RDBMS, IBM® DB2®, or the set of DB2 functionality available as part of IBM DB2 UDB components for Rational Products.

Depending on whether you are deploying Rational ClearQuest or Rational ClearQuest MultiSite, configuration tasks and restrictions might vary. Review the following sections closely to identify these tasks and restrictions.

If you are installing Rational ClearQuest MultiSite, do not create Rational ClearQuest databases at the replica site. When you replicate an existing Rational ClearQuest database set, you must create empty vendor databases at the new site, which the replication process then converts to a Rational ClearQuest database set.

You can use databases from different vendors in the same production environment. For example, you might want to use Oracle or Microsoft SQL Server databases for your schema repository and user databases, and a Microsoft Access database for your test database. However, this practice creates problems when you are using Rational ClearQuest MultiSite because case-sensitivity rules are not consistent across vendors.

Note: For detailed instructions on completing the tasks in the following topics, consult your database software documentation.
