The catalog structures for DB2 UDB and ASE are different. If you have client applications written to access the SQL Server catalog, you may need to re-code the client application queries to send those queries directly to the DB2 UDB system tables. To avoid modifying your database-specific applications, you can use CSPs to access catalog information. CSPs are compatible with the catalog interface for the Open Database Connectivity (ODBC) Application Program Interface (API).
You need to install and configure CSPs in TRS for the proper functioning of the following clients:
ODBC
ASE/CIS
