Figure 69 shows the format of the Loader and Program Storage Report. This report is produced using a combination of the EXEC CICS® COLLECT STATISTICS PROGRAM and EXEC CICS COLLECT STATISTICS STORAGE commands. The statistics data is mapped by the DFHLDGDS and DFHSMDDS DSECTs. The field headings and contents are described in Table 193.

Field Heading | Description |
---|---|
Loader | |
Library Load requests | The number of times the loader has issued
an MVS™ LOAD request to load programs from the DFHRPL library concatenation
into CICS managed storage. Modules in the LPA are not included in this figure.
Source field: LDGLLR |
Library Load Rate per second | The number of times per second the loader
has issued an MVS LOAD request to load programs from the DFHRPL library concatenation
into CICS managed storage. Modules in the LPA are not included in this figure.
Source field: LDGLLR / Elapsed seconds (since the last statistics reset) |
Total Program Uses | The number of uses of any program by the CICS system.
Source field: LDGPUSES |
Total Library Load time | The total time taken for the number of library
loads indicated by LDGLLR.
Source field: LDGLLT |
Program Use to Load Ratio | The ratio of program uses to programs loads.
Source field: (LDGPUSES / LDGLLR) |
Average Library Load time | The average time to load a program.
Source field: (LDGLLT / LDGLLR) |
Times DFHRPL secondary extents detected | The number of times the loader received an
end-of-extent condition during a LOAD and successfully closed and reopened
the DFHRPL library and retried the LOAD.
Source field: LDGDREBS |
Library Load requests that waited | The number of loader domain requests that were forced to suspend due to the loader domain performing
an operation on that program on behalf of another task. These operations could
be:
This figure is the total number of tasks that have waited, and does not include those that are currently waiting (LDGWLR). Source field: LDGWTDLR |
Total Library Load request wait time | The total suspended time for the number of
tasks indicated by LDGWTDLR.
Source field: LDGTTW |
Average Library Load request wait time | The average loader domain request suspend
time.
Source field: (LDGTTW / LDGWTDLR) |
Current Waiting Library Load requests | The number of loader domain requests that are currently forced to suspend due to the loader
domain currently performing an operation on that program on behalf of another
task. These operations could be:
Source field: LDGWLR |
Peak Waiting Library Load requests | The maximum number of tasks suspended at
one time.
Source field: LDGWLRHW |
Times at Peak | The number of times the high watermark level
indicated by LDGWLRHW was reached.
This, along with the previous two values, is an indication of the level of contention for loader resource. Source field: LDGHWMT |
Average Not-In-Use program size | The average size of a program currently on
the Not-In-Use queue.
Source field: ((LDGCNIU + LDGSNIU + LDGRNIU + LDGECNIU + LDGESNIU + LDGERNIU) / 1024) / LDGPROGNIU) |
Programs Removed by compression | The number of program instances removed from
storage by the Dynamic Program Storage Compression (DPSC) mechanism.
Source field: LDGDPSCR |
Time on the Not-In-Use Queue | The program Not-In-Use (NIU) queue membership
time. For each program that becomes eligible for removal from storage by the
DPSC mechanism, the time between the program becoming eligible and the actual
time of its being removed from storage is calculated. This field is the sum
of these times for all programs removed by the DPSC mechanism and as such
can be greater than the elapsed time CICS run time. This field does not include
the wait time for those programs reclaimed from the Not-In-Use queue.
Source field: LDGDPSCT |
Average Time on the Not-In-Use Queue | The average length of time that a program
is eligible for removal from storage by the DPSC mechanism.
Source field: (LDGDPSCT / LDGDPSCR) |
Programs Reclaimed from the Not-In-Use Queue | The number of reclaims that CICS has made from
the Not-In-Use (NIU) queue. Reclaims occur when a request is issued for programs
currently in the Not-In-Use queue. The reclaimed instance of a program is
no longer eligible for program compression (DPSC).
Source field: LDGRECNIU |
Programs Loaded - on the Not-In-Use Queue | The number of programs on the Not-In-Use
(NIU) queue.
Source field: LDGPROGNIU |
