3.1.1.13 CICCWG: Weekly CICS Service Trend

The Weekly CICS Service Trend inquiry produces a color graph
which shows the trend of CICS service in the past 9 weeks, as
well as the projected service for the next 8 weeks.  The
predicted values are generated by PROC GPLOT using linear
regression to fit a line through the actual data points.

REPORT FORMAT:

This inquiry produces an overlay plot, using two vertical
axes, which shows the trend in CICS average response time and
average transaction rate.  The average response time is
plotted against the left vertical axis, while the average
transaction rate against the right.  This plot is available
in color graphic format only.

INQUIRY ID:

     CICCWG (color graphic format)

DATA SOURCE (file/timespan):

     CICCSY in the weekly history file.

DATA ELEMENTS USED:

     CICSID   - CICS System Identifier
     CSYSRSTM - Short Response Time Total
     CSYSTRN  - Short Transactions Processed
     CSYMRSTM - Medium Response Time Total
     CSYMTRN  - Medium Transactions Processed
     CSYLRSTM - Long Response Time Total
     CSYLTRN  - Long Transactions Processed
     CSYTRANS - Total Transactions Ended
     CSYTRSTM - Total Response Time All Functions
     DURATION - Recording Interval Time
     WEEK     - Week of Year
     YEAR     - Year of Century
     ZONE     - Time Zone
     SYSID    - System Identifier

   CALCULATIONS:

     Average response time = CSYTRSTM/CSYTRANS
     Average short response time = CSYSRSTM/CSYSTRN
     Average Medium response time = CSYMRSTM/CSYMTRN
     Average long response time = CSYLRSTM/CSYLTRN

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.



     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.

     CENTER - Optionally, specify the CENTER to be reported.
              If no value is specified, the value *ALL is
              used which causes all CENTERs found in input to
              be summarized together.  CENTER is a logical
              grouping of SYSIDs which you assign in the
              global exit %GCNTR.  If this exit is not
              defined, CENTER is set to the value of SYSID.

     DATE   - Optionally, enter the date to be reported in
              ddmmmyy format.

     ZONE   - Optionally, select one or more CA MICS time
              zones.  Valid values are numbers 1 through 9.

     BY  -    Optionally, specify the BY variable (either
              SYSID or CICSID) to produce separate graphs for
              each system.  Otherwise, all SYSIDs and CICSIDs
              are summarized together and displayed on one
              graph.

     DEVICE - Optionally, override the default colors and
              patterns used by specifying a different device
              type.  The default is TERMINAL.  Because the
              code for color graphics is not generated by
              MICF, the device parameter you specified in
              MICF is not applicable here.

     FOOTNOTE-Optionally, specify whether or not the MICF
              inquiry ID should be displayed as a footnote on
              the graph.  The default value is NO.

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.

     In addition to the above exits, the module CICRPTGL also
     contains macro variables which set default values for
     service level objectives.  Please see Section 3.2 to
     override the default values.
