14.3 Summary of Scenario 3

In this chapter we described the various components that make up the CICS and

DB2 environments in our system and how they are set up.

We reviewed:

򐂰 Processing performed by the CICS DB2 Trader application

򐂰 Detailed a process which used Debug Tool, running under CICS, to identify a

problem with the logic in the application

򐂰 Provided a description of File Manager/DB2’s capability to correct the data

that resulted from the problem

Important: It is very important that you exit File Manager/DB2 before running

again the transaction. The database is freed only at the end of the File

Manager/DB2 session. If the database is still held, you may get PROG753 in

CICS.
