Siebel Database Upgrade Guide for DB2 UDB for z/OS > Basic Database Preparations for a Siebel Upgrade >

Backing Up the Database

Upgrades: All upgrades.

Environments: Development environment only.

Perform a full backup of the database. This backup protects your repositories and environment.

It is a recommended practice that you back up your database at key stages of the upgrade:

• Before any upgrade activity is started
• After upgrading the Siebel Database Schema or Custom Database Schema (upgrep + upgphys)
• After the repository merge

Perform any necessary maintenance on your Siebel database, for example running REORG or RUNSTATS, before backing it up. This ensures that your database is ready for use if you have to perform a database recovery.
