Detail line descriptions

Each line represents a System Object – an object to which CPU time is attributed. These lines are arranged hierarchically. You can expand a line (using the “+” line command) to reveal a breakdown into subordinate objects. Each type of object shown in this report is described here:

Task

This is the highest level object in the report. Each active Task is reported. The percentage of the total measured CPU time which was measured in this Task is reported. A SETUP option is available which specifies that all Tasks – including inactive tasks – are to be displayed.

Name Column: The name of the program specified in the ATTACH macro that started the task as well as the TCB index number is shown.
Description Column: The TCB address is shown. For CICS® measurements that have the CICS data extractor selected, the TCB mode is displayed for CICS TCBs. This immediately follows the TCB address.

Category

Activity within a Task is categorized as APPLCN, SYSTEM, DATAMG, DB2SQL, IMSDLI, ADABAS or NOSYMB.

DPA Group

Within a category – usually the SYSTEM category – load modules can be further arranged into Descriptive Program Attribution (DPA) groups. These are functional groups like: IMS™, DB2®, MVS™, SVC, etc. By entering a “+” on the SYSTEM category line:

Note: Note Using the SETUP primary command, you can specify aggregation of modules into Group or Subgroup. Subgroup offers a more granular, less inclusive categorization than Group.

In this sample screen Subgroup has been selected in SETUP, note that the SVC group has now been replaced with SVC subgroups (a subgroup for each SVC type.)

Load Module

A load module line appears under a Group/Subgroup line, under a Category line, or under an SVC line.

For example, to see the load modules under the Group/Subgroup line MVS, enter “+” on the MVS object:

Name Column: The load module name appears under this heading.
Description Column: If a DPA functional description is found for the module name, it is reported under this heading. Otherwise “Application Program” is displayed.

CSECT (Control Section)

These lines can appear as subordinate, breakdown items under a load module line. If Application Performance Analyzer was able to find ESD (External Symbol Dictionary) information, during the measurement process, for a load module, these items will appear under the load module and the measured activity will be attributed to them.

Name Column: The CSECT name appears under this heading.
Description Column: This will display “CSECT in xxxxxxxx” where xxxxxxxx is the name of the load module to which the CSECT belongs.

Source program mapping can be accessed from this line by entering a “p” line command.

SVC (Supervisor Call)

This line shows attribution of measured activity during execution of an MVS Supervisor Call.

Name Column: “SVC” followed by a 3-digit decimal SVC number (000 to 255) appears under this heading. For example, “SVC120.”
Description Column: A description of the SVC service, or the name of the macro which invokes the SVC appears under this heading. For example: “GETMAIN/FREEMAIN.”

DDNAME

These lines appear under the DATAMG category and indicate the DDNAME of a file to which CPU usage is attributed. The quantification indicates CPU time consumed in data management routines.

Data Management Request

These lines appear under DDNAME lines and show a further breakdown of CPU usage for the DDNAME to the specific I/O request statements.

SQL Statement

This item attributes measured activity to a DB2 SQL statement.

Name Column: A sequence number is assigned to each unique SQL statement observed during the measurement. This sequence number is shown in the name field. It is possible for some sequence numbers to be missing (sequence gaps) from the report. This will occur if a sequence number was assigned to SQL statements but no CPU activity was measured for these statements.
Description Column: The name of the program that issued the SQL request followed by the precompiler statement number (enclosed in parentheses) is shown here. This is followed by the SQL function (e.g. SELECT, INSERT, COMMIT).

DL/I Call

This item attributes measured activity to an IMS DL/I call.

Name Column: A sequence number is assigned to each unique DL/I call statement observed during the measurement. This sequence number is shown in the name field.
Description Column: The DL/I function code appears followed by the PCB name followed by the relative PCB number in parentheses. The location of the call. in csect+offset format, follows.

Adabas Call

This item attributes measured activity to an Adabas call.

Name Column: A sequence number is assigned to each unique Adabas call statement observed during the measurement. This sequence number is shown in the name field.
Description Column: The name of the program that issued the Adabas request and the offset within the program, followed by the Adabas command code that was issued, is displayed in this field. When Natural calls Adabas, the Natural program name and statement number are displayed. If the statement is within an INCLUDE member, the INCLUDE menber name is displayed.

Unresolved Address

This item attributes measurement activity to a range of addresses for which a corresponding load module name could not be determined.

Name Column: Activity observed in a 4096 (4K) byte range of addresses is reported in an Unresolved Address line. This range is expressed in the format “HHHHHxxx” where HHHHH are the 5 high order hexadecimal digits of the address. For example: “08915xxx” means the range from 08915000 to 08915FFF.
Description Column: “Unresolved Address” appears under this heading.
