Hi Merlin...  

We have an application that he uses one extfh that was modified by us
so that it has access Oracle bases natively through the use of
ProCobol.  I am interested in its work, would like to get greaters

We use Microfocus NetExpress 3.0.

> 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.

> 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.
