Applying the Nonadditive Schema Changes

Perform the following procedure to apply the nonadditive schema changes to the staging database.

If you are performing a development database upgrade, or if you are performing a production database upgrade but chose not to apply any additive changes in advance, all the Siebel CRM schema upgrade changes for the current release are now applied to the staging database.

To apply nonadditive schema changes

1. On the Staging Database Non-Additive Schema Menu, select option 4: Apply Non-Additive Changes, and press Enter.
2. Run the job using the JCL in data set DSNHLQ.SIEBEL.INSTALL.JCL(SCHEMAS).
3. After submitting the job, verify that the job ran successfully with a return code of 0 or 4. For information, see Verifying JCL Upgrade Jobs.
4. After submitting the job, enter cancel on the command line or press PF3 to save changes.
