The CICS PA perspective is by opened clicking the Open Perspective icon next to the shortcut bar, then clicking Other > CICS PA and then OK.
The Overview view provides you with the ability to display only a subset of the data in the database. You first select the data and time range for the data you want to display, and then you can reduce the selection further by selecting an Applid and a Transaction ID. The resulting data is displayed in the Sheet view. The view tab displays the database name followed by the total number of records in parenthesis. The sheet view is a fixed view that cannot be closed and it always reflects the data selected in the Overview view, the Tree view, or the Project Explorer view.
In the following screen capture, the CICS PA perspective is shown with an active database connection. The Sheet view is the primary view and this displays the selected records in the database. The analysis views are located below the sheet view, and the screen capture shows a CPU time analysis of the records selected in the Sheet view.
The Tree view displays the structure of the database in a tree format, in date, time, applid, and transaction ID order
If your data is in one or more csv files, they are displayed in projects in the Project Explorer view
