Tandem Capacity Model (TCM) Manual

The one-character transaction type code can be one of the following:
• X for an OLTP transaction
• B for a batch transaction
• Q for a query transaction
NOTE: Do not include a space between the one-character transaction type code and the
transaction name. Including a space between them will cause an error.
The transaction name can be up to 20 characters.
If you do not specify TXN entries, TCM uses the name of the Server (S type) process categories as
the default, and the TXN type is assumed to be X.
If you do not want to use the defaults (for instance, if you have batch transactions), you must list
all transaction names and their codes.
The maximum number of transactions that can be modeled is 40.
Running MeasTCM to Create CSV Files
Once you have edited the control file, MeasTCM has the information it needs to summarize the
specified Measure data and create the CSV files for downloading to TCM on the workstation.
To process the data, run MeasTCM. The length of processing time depends on the amount of
Measure data being summarized, the number of process categories defined, and the priority given.
During run time, MeasTCM creates these files:
• If you specify a report to be made, an intermediate file might be created if FastSort needs
one. This file is automatically deleted when processing finishes.
• The CSV files required by TCM.
Messages appear to inform you of the processing status. If a specified control file does not
exist, MeasTCM terminates with a completion message indicating that the control file does
not exist.
NOTE: HP reserves the right to change the format of the CSV file without notice.
Running MeasTCM
To run MeasTCM:
1. Set the optional EXECUTION-LOG parameter:
> [ PARAM EXECUTION-LOG { Tandem-file-name } ]
{ define-file }
The EXECUTION-LOG parameter must be set when you run MeasTCM with the NOWAIT
option. (See Step 2.) The parameter value controls the destination of the MeasTCM
informational messages and messages issued by the COBOL85 runtime library routines. If
there is no EXECUTION-LOG parameter, messages are sent to the home terminal.
2. Run MeasTCM by entering the following command. This example assumes that MeasTCM is
installed in the $SYSTEM.SYSTEM sub-volume.
2> MEASTCM [ / NOWAIT / ] cntlfile
cntlfile is the name of your control file.
If MeasTCM is not installed in the $SYSTEM.SYSTEM subvolume, specify RUN and enter the
fully qualified file name of the MEASTCM program:
2> RUN $DATA.ATTG.MEASTCM [ / NOWAIT / ] cntlfile
