Reducing Field Lengths of Unique Indexes to Avoid Truncation

Indexes on DB2 UDB for OS/390 and z/OS are limited to 255 characters. Indexes supplied by Siebel eBusiness Applications adhere to this limitation.

However, if you customize your development environment without setting the database options for DB2 UDB for OS/390 and z/OS, your indexes might be truncated upon migration to the DB2 host and could become nonunique. For more information, see Setting Database Options.

When analyzing your business needs, if the unique indexes seem too long, Siebel Systems recommends that you reduce the field lengths.
