Attribution

Attribution reports identify invocation sites of the system service routines that were responsible for CPU usage and CPU Wait.

The presentation uses a tree map method for displaying data.

CPU Usage Report details

Invoked Service

• Pseudo-Module shows the Strobe pseudo-module name of the invoked activity.
• Module shows the name of the load module in which the actual activity occurred.
• Section shows the name of the section in which the actual activity occurred.

• Description shows a short description of the function of the control section or pseudo-section, or of the module or pseudo-module. Function descriptions appear for all pseudo-sections and pseudo-modules, and, if your Strobe system programmer has supplied them, for other control sections and modules as well.
• CPU % Execution shows the percentage of CPU time spent in the invoked system routine on behalf of the invoking routine as a percentage of all CPU time used by programs executed in the measured job step.

Click  next to the Pseudo-module to view the following additional detail:

Was Invoked By

• Transaction shows the name of the transaction.
• Module shows the name of the load module to which the activity occurred.
• Section shows the name of the section to which the activity occurred.
• Location shows the program offset, in hexadecimal, to which activity was attributed.
• Line and Source Text/Description identifies either the line and source text associated with the program offset, or shows the description of a system program.

Via

• Module shows the module name of the program directly called by the invoker of the service.
• Section shows the section name of the program directly called by the invoker of the service.
• Description shows the description name of the program directly called by the invoker of the service.

Click  next to a transaction to view the following additional detail:

• Line number identifies the specific line number of the source statement associated with the location of the coll within the invoker.
• Source listing text of invoking statement provides the complete source statement even when spanning multiple lines.

For Db2, the report shows the following information about SQL statements:

• Transaction shows the name of the transaction that invoked this service. A value of NOTRAN signifies that no transaction was responsible for the service.
• Query shows the name of the Db2 Query that invoked the service module.

For Packages, DML, and SVCs:

• Stmt, Seq number, Line number, and Procedure/Description: line number of the invoking site, procedure name of the procedure at the invoking site.

For CA-IDMS, the report shows the following information about DML statements:

• Stmt shows the statement number.
• Transaction shows the name of the transaction.
• Dialog shows the name of the CA-IDMS dialog that invoked the serviced module.
• Location shows the offset of the statements invoking activity in CA-IDMS overhead routines, if the program was not compiled with the DEBUG DML compiler option.
• Process name shows the name of the process.
• Program shows the name of the external run unit.
• Function shows the function of the run unit.
• Return shows the DML command return offset.
• Seq number shows the DML sequence number of the run unit invoking activity in CA-IDMS overhead routines, if the program was compiled with the DEBUG DML compiler option.
• Version shows the version number of the control section or module.

For Natural statement attribution the report shows the following information:

• Transaction shows the name of the transaction.
• Include name shows the label of the included code.
• Stmt shows the NATURAL statement number
• Library shows the NATURAL program library name
• DBID shows the NATURAL program library database ID
• FNR shows the file number for the NATURAL program library

CPU Wait Report details

Function descriptions appear for all pseudo-sections and pseudo-modules, and, if your Strobe system programmer has supplied them, for other control sections and modules as well.
• Wait % Page shows the percentage of page wait time spent in the invoked system routine on behalf of the invoking routine as a percentage of all page wait time used by programs executed in the measured job step.
• Wait % Total shows the percentage of wait time spent in the invoked system routine on behalf of the invoking routine as a percentage of all wait time used by programs executed in the measured job step.
