Remote unit of work

This type of distributed access allows for reading or updating data at one remote location per unit of work.

DB2 UDB for z/OS Distributed Data Facility (DDF) adopted DRDA's data structure beginning with DB2 for OS/390 Version 2.3. With remote unit of work, DB2 UDB for z/OS can act as a server or requester (depending on the level of support from the partner system) for any remote database management system that implements DRDA.

If the startup program parameter DSQSDBNM or the QMF CONNECT command is used to specify a remote location to connect to, all subsequent QMF commands that access the database are directed to that location. (The CONNECT TO message appears on the QMF Home panel if DDF is installed.)

Figure 2 illustrates QMF with remote unit of work.

Figure 2. QMF using remote unit of work
In the diagram QMF connects to CICS, GDDM, DB2 Application Requester, and TSO. GDDM is connected to Terminal, and DB2 Application Requester is connected to DB2, SQL/DS, or DB2 for Application Server by either QMF DSQSDBNM parm from startup, or CONNECT command from QMF
