Complete the Prerequisites

Complete these prerequisites so that you can archive and purge data successfully.

Follow these steps:

1. Understand the database-related terms used in this scenario, as follows:

   When you install CA Service Catalog, you install the Catalog database. The Catalog database includes the following tables:

   • The CA Management Database (MDB) tables that apply to CA Service Catalog; their names typically begin with a CA_ prefix. The MDB is the common, shared database for CA Technologies products. The MDB provides the database schema for CA Service Catalog and other CA Technologies products.
   • The CA Service Catalog-specific tables; their names typically begin with a USM_ prefix.
2. Back up the Catalog database.

   Note: Log in to the Catalog database as the database application user; the user name is typically usm_user or mdbadmin. For detailed backup procedures, see your DBMS documentation.

3. Configure your DBMS to run with a low (minimal) level of logging. This configuration helps expedite database processing for CA Service Catalog.

   Note: See your DBMS documentation for instructions to set logging levels and for information about the impact of using low logging levels.

4. (Optional) Stop all antivirus services.
