Contains a list of transaction names and typesTXN (transaction) entries
The first section, environmental entries, is required. For applications with OLTP transactions only,
the three other sections are optional. For applications with batch transactions, the last section, TXN
entries, is required. If the last three sections are included, they must be specified in the order listed
in the template file.

MEASURE Entry
MEASURE data-file is a disk file containing data collected by Measure. It is required. Measfh
is the name of an object file containing a MEASFH program. The default is the current
$SYSTEM.SYSnn.MEASFH file. You can have multiple entries of this type:
MEASURE datafile1 [ measfh ]
MEASURE datafile2 [ measfh ]
CSVLO and CSVHI Entry
The CSVLO and CSVHI entries define the time window used to filter the data in all the specified
Measure files. These entries are recommended, but not required. If you do not supply one or both
of these times, MeasTCM determines an appropriate time based on the actual start and stop times
of the input Measure data files.
If no data occurs during the user-specified CSVLO to CSVHI time period, no CSVs are produced,
and MeasTCM displays an appropriate message.
HP recommends that the Measure data have intervals so the first and last intervals can be excluded
from the MeasTCM analysis by specifying appropriate CSVLO and CSVHI entries. The first and
last intervals might contain Measure startup or shutdown inconsistencies. The intervening period
or periods will contain data that is more consistent.
APPL Entry
Application is the name of the application for the Measure data sample (maximum 20 characters)
that you select. This entry is required. The first character of the application name must be a letter.
The following characters can be numbers or letters. No special characters can be used. The
