File IO Counts

documentation.microfocus.com/.../index.jsp

Hi Sawalter, the File Handler trace tool might give you what you need. It will record all the IO during execution and allows you to replay the IO without having to run the application again but you can also use it just to display the various IO operations that were performed using the file handler.

The trace tool is mainly used for internal purposes to help us diagnose file handling related problems.

I have created a tracing config file, extfh.cfg. this file is put in c:\\data\\log_files\\trace\\, and is activated by a line in the batch file

SET EXTFH=%LOGDIR%\\trace\\extfh.cfg

It works similarly to the config file MFTRACE_CONFIG.

I am having a couple of issues, though. The trace file is created after running the batch script, and in the right directory, but I cannot start the trace player that is necessary to display the results of the trace. Following the directions in documentation.microfocus.com/.../index.jsp I still get errors. Command to open the trace player is >cobfhrepro2 /ntracefile. The main error is Cannot open trace file.

Here's how it worked for me:

C:\\fh>type *.cbl

test.cbl

       select a-file assign "file.dat".

       fd a-file.

       01 a-rec pic x.

       move "x" to a-rec

       open output a-file

       write a-rec

       close a-file

C:\\fh>cobol test.cbl int() ;
