Setting Database Options

When developing applications on any platform (for example, DB2 for Windows) that will eventually be deployed on DB2 for z/OS, you must set the appropriate database options in Siebel Tools. Setting these options enables all Siebel Tools features for DB2 for z/OS and validates Siebel objects for the z/OS operating system:

• CHAR columns with a length greater than 1 are allowed.
• Users can eliminate unused indexes.
• Users can reduce the size of VARCHAR fields.

1. Start Siebel Tools.
2. From the Tools menu, choose View, and then the Options menu item.

   The Development Tools Options dialog appears.

3. On the Database tab, select the Developing for deployment on DB2 for zSeries check box.
