A DB2 access service works with the Mainframe Connect DB2 UDB Option for CICS and the Mainframe Connect DB2 UDB Option for IMS to allow clients to access DB2 UDB data. Each access service has a specific set of configuration properties that:
Transforms SQL
Converts datatypes
Supports RPCs
Transfers data between DB2 UDB and other servers accessible through Open Client
Supports Catalog Stored Procedures (CSPs) and system stored procedures
Supports remote stored procedures (RSPs) and host-resident requests
For more information, see the Mainframe Connect DirectConnect for z/OS Option Users Guide for DB2 Access Services.
