Using the CICS® PA plug-in you can perform threadsafe, CPU time, response time, storage, and file analysis, and view the data graphically.
Before you begin
Check that the analysis that you want to perform is available. The CICS PA plug-in provides the ability to restrict the number of charting options available by disabling different categories of analysis. To check the analysis types currently enabled, click Window > Preferences > IBM CICS Performance Analyzer > Categorization enablement. The Categorization enablement dialog is displayed showing the different types of analysis. If an item has no check mark against it, the options associated with the item will not be available, and you cannot perform that type of analysis. Select or deselect analysis types as required.
Displaying the data for analysis
Pie charts are displayed in the Transaction detail view. The pie charts contain a detailed breakdown of a single transaction ID in the time period selected. You display the Transaction detail view in the following way:
The Transaction detail view is displayed. Click a pie chart to show the details for a specific analysis type. In the following screen capture the Transaction detail view is shown with the CPU time pie chart selected displaying detailed CPU time information for the selected transaction ID.
The Transaction detail view contains one or more pie charts depending on the data selected and categorization enablement. For example, if the Storage categorization enablement is not selected the Storage pie is not displayed. Similarly, if there is no file usage data in the selected sample, the File usage pie chart is not displayed.

A bar chart displays a bar for each transaction selected. Each bar contains one or more sectors, each sector representing different information depending on the selection type. You display a bar chart in the following way:

A timeline
chart displays all instances of a transaction ID in
the selected application ID across either the whole data file, or
a range of dates specified using the Date dialog when selecting the
data. For example, selecting the single record with a transaction
ID of CRTP in an application ID of IYCYZC20 displays
a bar for every instance of the transaction ID in the application.
You display a timeline chart in the following way:
The data in the Sheet view is refreshed to show only the data with in selected date range. You can now select the single transaction in the sheet view and repeat the above steps to show only the timeline data in the selected date range.
You can select one or more bars and perform a further analysis on the information by right-clicking and selecting a new analysis from the pop-up menu.
By using multiple timeline charts you can compare the way transaction are performing in one application against the way they perform in another application, and identify potential problems. The following screen capture shows the timelines for the same transaction ID over the same period of time, but running under different applications.
