Customizing QMF to work with a DB2 UDB for OS/390 for AIX server requires some changes both on the host and the server.
From OS/390, QMF uses the distributed data facility (DDF) of DB2 UDB for OS/390 to access distributed data that resides in a DB2 UDB for OS/390 for AIX database. The DDF of DB2 UDB for OS/390 is a VTAM application that uses LU 6.2 communications protocols to communicate with other database management systems or applications that support Distributed Relational Database Architecture (DRDA). Information about connecting distributed database systems for access to data from QMF on OS/390 is in DB2 UDB for OS390 Administration Guide , Volume 1.
From DB2 UDB for OS/390, the communications database (CDB) tables are used to control access between remote database management systems. If you plan to use DB2 UDB for OS/390 as a server only, you do not need to populate the CDB; default values are used. However, if you intend to request data from remote databases, you must update the CDB tables. These topics are described in the DB2 UDB for OS390 Administration Guide , Volume 2 and DB2 UDB for OS390 SQL Reference.
At the DB2 UDB for OS/390 for AIX server, you must issue a CREATE DATABASE command before installing QMF into that database. Verify that APPC communications are defined and operational between the DB2 UDB for OS/390 for OS/390 DRDA application requester and the DB2 UDB for OS/390 for AIX DRDA application server. For more information about installing your DB2 UDB for OS/390 for AIX server, refer to the installation instructions for that DB2 UDB for OS/390 for AIX server.
