Detail line descriptions

Each line represents a System Object – an object to which measured activity 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:

Category

Category is the top level in the hierarchy. CPU consumption is categorized as APPLCN, SYSTEM, DB2SQL, DATAMG, 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: 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.)

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.
CPU Percent Column: The measured CPU execution for this Load Module appears under this heading.

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.

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.”

SQL Statement

This item attributes measured activity to a DB2 SQL statement.

Name Column: A sequence number is assigned by Application Performance Analyzer to each unique SQL statement observed during the measurement. This sequence number is shown in the name field. It is possible for some sequences 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.
