5.2.7.3 CICCSY Usage Considerations
This section identifies some special considerations or
techniques for using the CICCSY File.
1. The following data elements are defined within the
CICGENIN member of sharedprefix.MICS.GENLIB and are
reserved for user derivation:
CSYSRU - System Resource Units
CSYEXCPS - I/O (EXCPs) Generated
CSYSERVU - Service Units
CSYSRMTR - SRM Ended Transactions
CSYCONTM - Terminal Connect Time
2. The following data elements are dependent upon the
options set within the prefix.MICS.PARMS(CICOPS) member
or the prefix.MICS.PARMS(SYSID) member. This dependency
is outlined below.
prefix.MICS.PARMS(SYSID)
CSYCPUNI - Instructions Executed
prefix.MICS.PARMS(CICOPS) - parameter RESP
CSYRVAL1-CSYRVAL8 - Response Distribution Limits
3. The ENDTS and STARTTS, when appearing in the DAYS, WEEKS,
MONTHS, or YEARS timespans, bound the span of time over
which the data has been summarized, with STARTTS being
the lowest date and time, and ENDTS the highest date and
time for the data summarized.
4. The data elements in the following list do not exist in
the DETAIL timespan for the CICCSY File. These data
elements are not derived from the raw data, but rather
are derived by a summarization of the CICCSU DAYS file.
CSYCDST1 - CSYCDST8 - Count Conv. Responses In Limit
CSYCRSTM - Conversational Response Time Total
CSYCTRN - Conversational Transactions Processed
CSYDAMSC - Damaged Storage Chain
CSYERSTM - Excessive Response Time Total
CSYETRN - Excessive Transactions Processed
CSYINCH - Input Message Character Traffic
CSYINVPA - Invalid CMF Call Encountered
CSYLDST1 - CSYLDST8 - Count Long Responses In Limit
CSYLRSTM - Long Response Time Total
CSYLTRN - Long Transactions Processed
CSYMDST1 - CSYMDST8 - Count Medium Responses In Limit
CSYMRSTM - Medium Response Time Total
CSYMTRN - Medium Transactions Processed

CSYSRSTM - Short Response Time Total
CSYSTRN - Short Transactions Processed
CSYTMERR - CMF Timing Error Encountered
CSYTRANS - Total Transactions Ended in Interval
CSYTRSTM - Total Response Time All Functions
5. CICS System File User Data Accumulation
While most data elements in the CICCSY File contain
system data, some elements originate from the CICCSU File
and provide transaction statistics. This combination of
elements allows the CICCSY File to retain a complete
picture of system activity. This is necessary because
response time distribution or system stress data is not
in the system records produced by any supported monitor.
The data elements derived from the DAYS.CICCSU
transaction data are:
CSYCDSTX - Count Conv. Responses Within Limit
CSYCRSTM - Conversational Response Time Total
CSYCTRN - Conversational Transactions Processed
CSYDAMSC - Damaged Storage Chain
CSYERSTM - Excessive Response Time Total
CSYETRN - Excessive Transactions Processed
CSYFCTOT - Total File Requests
CSYIMSGS - Input Messages Issued
CSYINCH - Input Message Character Traffic
CSYINVPA - Invalid CMF Call Encountered
CSYLDSTx - Count Long Responses Within Limit
CSYLRSTM - Long Response Time Total
CSYLTRN - Long Transactions Processed
CSYMDSTx - Count Medium Responses Within Limit
CSYMRSTM - Medium Response Time Total
CSYMTRN - Medium Transactions Processed
CSYMXCTM - Max Conversational Response Time
CSYMXETM - Max Excessive Response Time
CSYMXLTM - Max Long Response Time
CSYMXMTM - Max Medium Response Time
CSYMXSTM - Max Short Response Time
CSYMXTSK - Max Tasking Condition
CSYMXTTM - Max Response Time All Functions
CSYOMSGS - Output Messages Issued
CSYOUTCH - Output Messages Character Traffic
CSYSDSTx - Count Short Responses Within Limit
CSYSIOCT - Access Method Calls
CSYSOS - Short On Storage Condition
CSYSRSTM - Short Response Time Total
CSYSTRN - Short Transactions Processed
CSYTDSTx - Count Total Responses Within Limit
CSYTMERR - Monitor Timing Error Encountered
CSYTRANS - Total Transactions Ended
CSYTRSTM - Total Response Time All Functions
During the summarization process for the DAYS.CICCSY
File, a subset of the DAYS.CICCSU DAYS data is created
(the CSR work file). This file contains the data
elements being carried over from the transaction data to
the CICCSY system records. The CSY data being summarized
and the CSR data previously created is then merged to
create the complete CICCSY observation for this CICS
system.
Note: Missing CICS system records will cause transaction
data for that interval to be lost.
Example:
The data element CSYTRANS is the number of transaction
records for the interval. This statistic is not
contained in the CMF global records or the monitor task
accounting system records, so it must be derived from the
transaction data. During the special daily summarization
process for the CSY file, the summarized DAYS.CICCSU00
file is passed and certain data elements are extracted,
including CSUTRANS. The intermediate file, called
CICCSR, is sorted into CICCSY DAYS timespan sequence.
Then CICCSR and DAYS.CICCSY00 are input into the same
DATA statement. The values of CSUTRANS are summarized
into a retained data element called SSYTRANS. When the
associated CICCSY record is encountered and rewritten,
the value of CSYTRANS is assigned from SSYTRANS, and
SSYTRANS is reset to zero.
