Figure 1-2 shows the relationship of the DB2 access service library and TRS library with various components of the client workstation, LAN, and mainframe environments.
Due to space constraints, Mainframe Connect is abbreviated
to “MC.”
Figure 1-2: DirectConnect for z/OS Option environment
As shown, the request from a client application goes over the LAN to the DirectConnect server. From there, either TRS or a DB2 access service routes the request to the appropriate CICS region. Then, the request accesses data on the DB2 UDB database.
For more information on how to create multiple TRS libraries, see “Creating additional TRS configurations”.
