Link Pack Area Report

The Link Pack Area report provides information about the use of the modified, fixed, and pageable link pack areas. This report can be used as a guide for determining where a link pack area module should reside and for packing the PLPA and MLPA to reduce page faults.

The Link Pack Area Report is produced by using the LINKPACK Analyzer control statement. The data for this report is obtained by using the LINKMAP Extractor control statement and defining GBLS=YES to the REPORT Extractor control statement.

The Link Pack Area Report is divided into four sections with an optional fifth section:

  • Performance Statistics

    This section lists module counts for the MLPA, FLPA, and PLPA, in both the lower and extended areas. It also shows the user-supplied threshold rank for the run.

  • Link Pack Area Module Mapping

    This section lists LPA modules sorted by page address. The action flag included in this section marks LPA pages, which contain modules with different levels of activity. Such modules are often candidates for inclusion in the packlist.

  • Portion of the Link Pack Areas Selected for Potential Substitution into the Packlist

    This section lists all modules with a busy rank greater than the threshold rank, sorted in descending order by busy rank.

  • Time in Use

    This section lists all modules with a busy rank greater than zero (one section each for the MLPA, FLPA, and PLPA). You can use these reports to make decisions regarding packlist inclusion and FLPA module placement.

  • Map Error Log

    This report is generated only when errors occur. Any of the following errors might be reported:

    • module name mismatch: More than one entry was found for the same location, but the module names were not the same.
    • module length mismatch: More than one entry was found for the same location, but the module length was not the same.
    • address mismatch: More than one entry was found for the same location, but the entry points were not the same.
    • lower flag mismatch: More than one entry was found for the same location, but the characteristics of the entry were not the same. (State indicators.)
    • extended flag mismatch:More than one entry was found for the same location, but the extended characteristics of the entry were not the same. (Location and type indicators.)
    • unknown: A mismatch between at least two entries was found, but it could not be resolved into one of the previous categories.

If the LPA configuration was changed during the interval covered by the input data, two or more Link Pack Area reports are produced.

Note

This report requires the -16 records written at CMF MONITOR Extractor initialization, where xxx is the SMF ID for the CMF MONITOR user records (the default is 240). To obtain the desired report, ensure that the input data includes the records written when extraction began. It is not necessary to include the reporting period of these records in the DATETIME or SHIFT ranges.

An example of the Link Pack Area Report is shown in the following figure.

If an action flag (shown as ****) is displayed in this report, it might not require action. Sometimes the system automatically assigns smaller modules to whatever space is available in the PLPA page. In such situations, it might not be possible or desirable to make changes.

In the PLPA Modules by Time in Use section, the PAGE FIXED PCT value is calculated as

# of times at least one page was fixed for a module / # of times the module was active

In this same section, the PERCENT PAGE FAULTS value is calculated as

page fault observations for the module in LPA / page fault observations for all modules in LPA

Link Pack Area Report field descriptions

Field

Description

MODULE COUNT

number of modules in PLPA, FLPA, MLPA, or CSA

PAGE FIXED PCT

this field is blank

THRESHOLD RANK

user-supplied value with two functions:

  • to determine the level of activity a module must reach before being included in the substitution section
  • to describe the allowable tolerance of differences in the busy ranks of modules in the same page

ACTION FLAG

four asterisks (****) are printed whenever a busy rank for a module sharing a page with another module has a difference greater than the user-supplied threshold value

BUSY RANK

number of references to a module

MODULE NAME

name of the link pack area module

MODULE LENGTH

length of the link pack area module in bytes

PAGE ADDRESS

hexadecimal address of the page that this module occupies in the link pack area

% MLPA ACTIVITY

percentage of MLPA activity that was caused by this module

LOAD ADDRESS

load address of this module

PAGE FIXED PCT

percentage of times (frequency) that this module was observed in fixed pages

FRAME USAGE

number of pages in the module where BUSY RANK was greater than zero

% MLPA PAGE FAULTS

percentage of MLPA page faults caused by this module

% PLPA ACTIVITY

percentage of PLPA activity that was caused by this module

% PLPA PAGE FAULTS

percentage of PLPA page faults that were caused by this module

% FLPA ACTIVITY

percentage of FLPA activity that was caused by this module

% FLPA PAGE FAULTS

percentage of FLPA page faults that were caused by this module
