Function

The MCF performance verification trace definition defines the execution environment for acquiring MCF performance verification trace information.

Explanation

set format operands

prf_file_size=MCF-performance-verification-trace-information-file-size

~<unsigned integer> ((1024-1048576))<<1024>> (units: kilobytes)

Specify the size of a MCF performance verification trace information file.

Normally, trace information is output to regular files in OpenTP1. The number of generations of this file is specified by the prf_file_count operand in the MCF performance verification trace definition. When all generations have been used, the oldest file is overwritten with new trace information. Accordingly, old trace information is lost as time passes. You can increase the interval at which the oldest file is overwritten by increasing the value of this operand.

You can use the following formula to calculate the size of one trace file (units: bytes):

Size of one file = 128 + (trace-data-size#-necessary-for-one-transaction x number-of-transactions-to-execute)

#
To calculate the trace data size necessary for one transaction, see the manual OpenTP1 Operation.

prf_file_count=number-of-generations-for-MCF-performance-verification-trace-information-files

~<unsigned integer>((3-256)) <<3>>

Specify the number of generations for the MCF performance verification trace information file.

When a small value is specified, the system controls the trace files only within the new generations, and as a result, trace files outside this range may remain unused. In such a case, delete the files outside the range as needed.

Note

Use this definition only when TP1/Extension 1 is installed. If TP1/Extension 1 is not installed, the definition might not work correctly.
