Siebel Database Upgrade Guide for DB2 UDB for z/OS > Planning A Siebel Database Upgrade >

Staging and Target Database Planning

When scheduling your upgrade, be aware that the target database schema must not be changed after the staging DDL is produced. If target database schema changes are applied before the upgrade is completed, you must recreate the staging database and generate the upgrade files again.

When planning your upgrade, keep in mind the following:

• The staging database must be in a separate DB2 subsystem to the target database
• The staging database table space names must be same as those in the target database
• The staging database tableowner and storage group names may be same or different to the target database names

DB2 DSNZPARM Settings For the Target Database

For Siebel Business Applications to run correctly and efficiently, the DSNZPARM parameters for your target database must be set correctly. For a list of the Siebel required and recommended DSNZPARM parameter settings for DB2 for z/OS v8, see Implementing Siebel Business Applications on DB2 for z/OS.
