The Weekly CICS Performance Summary Report shows the
workload, service, and percent availability of each CICS
region in a given week. The report also shows the
occurrences of abnormal conditions that impact CICS
performance, such as high number of program compressions,
short-on-storage, and maximum tasks conditions. Once a
problem has been detected using this report, you can then
select one of the detail reports in the service or workload
area to further investigate the cause of the problem.
REPORT FORMAT:
This inquiry produces a tabular report which provides a
summary line for each CICS region found in input. In
addition, the report provides a summary line for overall CICS
performance for the enterprise (summed across SYSIDs and
CICSs), as well as CICS performance at the system level
(summarized by SYSID). A sample output of this inquiry is
shown in Figure 3-34. Each field in the report is described
below:
SYSID: System identification. This field is set to ALL
for data that is summarized for all systems.
CICSID: CICS system identification as assigned by
CA MICS. This field is set to ALL if the data is
summarized for all CICS regions.
AVG RESP: The average response time for all transactions,
excluding those assigned as TRANTYPE X in your
CICRLRT exit in prefix.MICS.PARMS.
TRANS: The total number of transactions processed,
excluding those assigned as TRANTYPE X in your
CICRLRT exit in prefix.MICS.PARMS.
%AVAIL: The CICS availability expressed in a percentage.
This number is derived by dividing the total CICS
uptime by the total report duration.
CPU TOTAL: The total amount of TCB and SRB time consumed.
This also includes subtask time for CMF.
CPU Percentage of total CPU time consumed by user
%USER: transactions.
CPU Percentage of total CPU time consumed by task
%KCP: control (system overhead).
CPU Percentage of total CPU time consumed by journal
%JCP: control (system overhead).
CPU Percentage of total CPU time consumed by terminal
%TCP: control (system overhead).
CPU Percentage of SRB time out of total CPU time.
%SRB:
CPU Percentage of subtask time out of total CPU time.
%SUB:
DSA SIZE: The size of CICS dynamic storage area as defined
in the SIT (system initialization table).
DSA HWM: The maximum dynamic storage area used.
COMPRS: The number of program compressions performed.
SOS: The number of time CICS experienced short-on-
storage condition due to release of the storage
cushion.
MAXTASK: The number of time CICS experienced MAXTASK
conditions and stopped initiating new tasks.
VIOL: The number of transactions with storage
violation.
% ABND: The percentage of transactions that abended for
this application.
INQUIRY ID:
CICLWP (tabular report)
DATA SOURCE (file/timespan):
CICCSY01 in the WEEKS timespan.
DATA ELEMENTS USED:
CICSID - CICS System Identifier
CSYABEND - Abnormal Terminations
CSYADSTM - Total Address Space Time
CSYCPUTM - Total CPU Time
CSYDAMSC - Storage Violations
CSYDSASZ - DSA Size
CSYETRN - Excluded transactions
CSYMEMSZ - DSA High Water Mark
CSYMXTSK - Max Task Conditions
CSYPCMDC - Number of Program Compressions
CSYSOS - Short-on-storage Conditions
CSYSRBTM - SRB Time
CSYTCPTM - Terminal Control CPU Time
CSYTCUTM - User CPU Time
CSYCPJTM - JCP CPU Time
CSYTRANS - Transactions Processed
CSYTRSTM - Transaction Response Time Total
CSYTSRTM - Task Control CPU Time
CSYUPTM - CICS Availability Time
MONTH - Month of Year
YEAR - Year of Century
ZONE - Time Zone
SYSID - System Identifier
CALCULATIONS:
Average response time = CSYTRSTM/CSYTRANS
Percent abend = CSYABEND/SUM(CSYTRANS,CSYETRN)
Percent availability = CSYUPTM/calculated up time
Percent user CPU = CSYTCUTM/CSYADSTM*100
Percent KCP CPU = CSYTSRTM/CSYADSTM*100
Percent JCP CPU = CSYCPJTM/CSYADSTM*100
Percent TCP CPU = CSYTCPTM/CSYADSTM*100
Percent SRB CPU = CSYSRBTM/CSYADSTM*100
Percent SUB CPU = (CSYADSTM-CSYTCBTM)/CSYADSTM*100
EXECUTION-TIME PARAMETERS:
UNIT - Select one or more CA MICS data base units by
entering the data base IDs. Enter multiple IDs
with a blank following each ID value.
CYCLE - Optionally, define CA MICS input file cycle
range.
For this inquiry, the default is the 01 cycle.
SYSID - Optionally, specify the SYSID to be reported.
If no value is specified, the value *ALL is
used. It causes all SYSIDs found in input to
be summarized together.
CICSID - Optionally, specify the CICSID to be reported.
If no value is specified, the value *ALL is
used which causes all CICSIDs found in input to
be summarized together.
DATE - Optionally, enter start of the report period in
ddmmmyy format.
For this inquiry, the default is the previous
week.
ZONE - Optionally, select one or more CA MICS time
zones. Valid values are numbers 1 through 9.
USER EXITS:
If the MICF execution-time parameters are insufficient
to select the data you need, you can invoke one of the
following global exits to further manipulate the input
file. Additionally, you can override the global exit
definitions in MICF using independent source statements.
For detailed information on coding the exits, refer to
Section 3.2 of this guide.
The global exits are defined by macros in the source
module CICRPTGL in sharedprefix.MICS.SOURCE. The
following exits are available to this inquiry:
%GCIC - Select CICSIDs for report.
%GCNTR - Assign value to the variable CENTER which
defines the logical grouping of SYSIDs.
CENTER is set to SYSID by default.
%GSYS - Select SYSIDs for report.
