Tran

The Tran page shows IMS or CICS activity in terms of individual transactions. This option displays the percentage of time CA Mainframe Application Tuner detected activity for each transaction.

Menu commands available on the Tran page are as follows:

  • Code Details
    Displays the Code Details subpage for the selected transaction. The activity of the modules and CSECTs running under the transaction are reported.

  • CallerID Details
    Displays the CallerID subpage for the selected transaction. The programs which executed the transaction are reported.

  • Delay Details
    Displays the Delay Details subpage for the selected transaction. The delays associated with the transaction are reported.

  • Data Details
    Displays the Data Detail panel for the selected transaction. The data sets associated with the transaction are reported.

  • IMS Statements
    Displays the IMS Statements subpage associated with a selected row.

  • DB2 Statement Details
    Displays the DB2 Statements subpage associated with a selected row.

  • Datacom Statement Details
    Displays the Datacom Statements subpage associated with a selected row.

  • Adabas Statement Details
    Displays the Adabas Statements subpage associated with a selected row.

Tran Columns

  • Tran
    The name of a transaction detected by CA MAT during the monitoring of an IMS or CICS region. CA MAT displays all unique transaction codes and summarizes their activity in each row.

    Note: The value N/A summarizes the activity of samples which could not be attributed to any specific transaction.

  • D
    The D field contains a Y if Data set detail information is available for this Transaction.
    Issue the N (Data Detail) line command to display the DataView Detail panel, which provides detailed information about which data sets were associated with the Transaction.

  • #Trans
    The number of times this transaction completed during the monitored period.

  • Avg RESP
    The average time (in seconds) for this transaction during the monitored period.

  • Tot CPU

    • Avg CPU
      The average CPU time required for this transaction during the monitored period.
      Calculated by dividing the total CPU time by the number of times the transaction completed during the monitored period.

  • Active %
    The percentage of the monitored period that the transaction was processing application code only. The value in this field does not include CPU time spent in systems services or SVCs.

  • Data %
    The percentage of the monitored period that CA MAT detected data-related delays. Data delays occur when the application program requests data be brought into or written from virtual storage.
    Data delays include I/O time to standard files and delays when interacting with a database management system such as IMS/DB or DB2.

  • Other %
    The percentage of the monitored period that CA MAT detected delays in the application that did not fit any of the following delay categories:

    • %CPU ..... program active time

    • %Data .... waiting on data

  • Total %
    The sum of all other columns. It reflects the total percentage of delay for this transaction.

  • Average SUs
    The average number of CPU Service Units required to process a transaction. CA MAT calculates this amount by using the following formula:
    (Avg CPU * 16000000) / CPU Adjustment Rate
    The CPU Adjustment Rate can be see on the OverView report.

  • Total SUs
    The total amount of CPU time in service units used by this transaction.
    CA MAT calculates this amount by using the following formula:
    (Tot CPU * 16000000) / CPU Adjustment Rate
    You can view the CPU Adjustment Rate in the OverView report.

DB2 Statement Details

The Statement Detail subpage displays details about the statement selected in one of the other pages.

Listing

The Listing subpage shows the compile listing of a CSECT that has been registered in CA Mainframe Application Tuner.

When you invoke the Listing subpage from a particular statement, that statement is highlighted in the listing.

Module/CSECT Information

The Module/CSECT Info subpage displays information such as size, location, and link date for a load module selected in the one of the other pages.
