Hi Carlos, I am working on project right now you might be interested in, namely a extfh interface to postgresql and a isam wrapper for libpq. I already have an isam bridge working direct to postgresql from AcuCobol without using odbc or a commercial driver. I just need to convert it to extfh and do a few other things to support microfocus.

Subject: [ODBC] Application bottlenecks
We are using Cobol Microfocus and pgsqlODBC to access Postgresql.
Originally these applications only accessed Oracle databases without ODBC, only Procobol and now we´re migrating to Postgresql and ODBC. The application logic doesn´t changed, but some applications have higher response times than the Oracle version. We worked on database tunning but even so, the response times are very different.
I turned on logging sql statemants in the server (log_duration) and discovered that the sum of all SQL duration times gives only 30% of the total response time felt at the client. This gives me a suspect that the bottleneck is outside the server.
Am I in the right way?
How can I discover the SQL duration times at the client? Is there some tool I could use?
Thanks in advance!
