Introduction › The Interactive Analysis Menu Options

The Interactive Analysis Menu Options

After you have specified an analysis option for a monitor definition, CA Mainframe Application Tuner loads the data and displays the Interactive Analysis menu. Each option on this menu displays the data from a different perspective.

These menu options are described next.

OverView option 0

Displays information about the monitoring process, as well as key global statistics about the monitored application.

These statistics can help you determine the next most logical panel to display as you continue your analysis effort.

TaskView option 1

Displays information about the performance of each z/OS task in the monitored address space.

If you select a task, CA Mainframe Application Tuner recomputes the values by using only samples from the selected task on all subsequent screens that you display, which enables you to focus on the performance of that task.

DelayView option 2

Divides the program into functional delay types.

Delay types comprise everything that contributes to the elapsed time of the program, including the time that the program was executing. See the chapter "Tuning Your Applications" for a comprehensive list of delay types identified by DelayView.

CodeView option 3

Displays the execution and wait time of each module used by the program.

You can display this information in greater detail down to the CSECT level. You can define Pseudo Groups, which are specific to your environment, to summarize the information for multiple modules. This feature enables you to identify time consuming areas of code and to associate subroutines within a program and program modules within an application framework.

TimeView option 4

Displays program activity in time sequence.

Each row of information represents a single sample taken during the monitored period. This format helps you determine a program’s execution path and looping logic. This format also gives a good indication of which code sections executed and when they executed during the monitored period.

DataView option 5

Displays data sets, databases, IMS, and DB2 statements that caused activity during the monitored period.

The data is sorted in descending order by activity. You can select a particular data set, database, IMS, or DB2 statement to display greater detail.

TranView option 6

Shows IMS or CICS activity in terms of individual transactions

It displays the percentage of time CA Mainframe Application Tuner detected activity for each transaction in the six major activity and delay categories. If you select a transaction, CA Mainframe Application Tuner recomputes the values on all subsequent screens that you display by using only samples from the selected transaction. This feature enables you to focus on the performance of that transaction.

ModView option 7

Displays the activity of each load module.

From ModView, you can hyperlink to module details or to a panel that suggests a linkage order for reducing system paging.

PoolView option 8

Displays statistics about IMS VSAM/LSR and VSAM/GSR buffer pool usage.

PoolView provides information about hit ratios, size and number of buffers, and total space requested. You can also display information about the data sets attached to a pool.

USSView option 9

Displays information about USS activity on a process basis

This option allows you to see delay information by process, code details by process, and process level information.

DB2 option 10

Displays statistics about DB2 activity.

IMS option 11

Displays statistics about IMS activity.

JVM option 12

Displays statistics about Java Virtual Machine (JVM) activity.

WAS option 13

Displays statistics about WebSphere Application Server activity.

CIC option 14

Displays summary statistics about CICS activity.

IDMS option 15

Displays statistics about CA IDMS activity.

DCM option 16

Displays statistics about CA Datacom activity.

IDL option 17

Displays statistics about CA Ideal activity.

ADA option 18

Displays statistics about Adabas activity.

NAT option 19

Displays statistics about Natural activity.
