CA 2E Implementation of DRDA

CA 2E's DRDA support makes it possible for you to generate applications that access files distributed over many systems. CA 2E functions can be created with distributed file I/O control set to CA 2E. With this option, the relational databases accessed by the function are controlled by a distributed file configuration table that you can maintain.

The use of a table to control access permits changes to the relational database (RDB) configuration without the need to change application code. This means that you can put the same program objects on several IBM i distributions, with different configuration tables on each one.

CA 2E's DRDA support provides the following features:

• Design of applications for distributed data processing
• Access of the same file name across multiple systems (not as a unified database)
• Implementation-level Distributed File Configuration Table
• CA 2E-generated iteration loops or user-defined control for error handling for CONNECT failure
• User access for specification of the RDB name used in the SQL CONNECT statement
• Access to either DDS or SQL files
