because they provide all available information. To focus on the desired problem area or to

minimize the size of the report, specify the date and time range or selection criteria, or both.

The IMS Connect Trace report provides a list of transactions, each with detailed information

about every event in the life of that transaction. You can see when a transaction starts,

followed by all the events associated with the transaction in the order they occurred.

Example 11-22 shows a sample trace report for a commit mode 1 sync level confirm

transaction.

11.2.8 IMS Problem Investigator

APAR PQ92211 in IMS Problem Investigator Version 1.1 introduces support for IMS Connect

Extensions event record analysis.

You can use IMS Problem Investigator for z/OS to analyze IMS Connect event data. IMS

Problem Investigator offers its full reporting and viewing capabilities to assist in the analysis

of event data in Archive Journal data sets. Archive File Selection is available for automatic

selection of archive data sets for batch analysis of an IMS Connect system.

IMS Connect Extensions settings

Before using the IMS Connect Extensions events in IMS Problem Investigator, you have to

define the IMS Connect Extensions settings. Follow these steps:

1. From the Primary Option Menu, select option 0

Profile, and then from the submenu select

option 4

IMS Connect Extensions Settings. Figure 11-11 on page 185 shows the menu.

Chapter 11. IMS Connect Extensions 185

Figure 11-11 IMS Connect Extensions Settings menu

2. Specify:

– The Log Record Code that IMS Connect Extensions assigns to the event records. The

default is A0.

– The name of the IMS Connect Extensions Definitions Data Set that defines the IMS

Connect systems and archive data sets on which you want to report.

IMS Connect Extensions event analysis

To access to the IMS Connect Extensions Archive Journals, follow these steps:

1. Select option 6

Connect from the Primary Option Menu to view the list of IMS Connect

systems and archive data sets. Figure 11-12 shows the IMS Connect System Definitions

panel.

2. You can specify S to display the list of Archive Data Sets, as shown in Figure 11-13.

Figure 11-13 Archive Data Sets for IMS Connect Extensions list

3. You have three valid line actions:

– SUB to submit a report or extract request for the system.

– S to select this data set for processing (IMS Problem Investigator Formatted Browse).

– P to add file to the Process Log Files list. The data set name is placed at the top of the

list from where you can then select it for dialog or batch processing.
