in Apache::DBI? Or something
else in your own code?
We use Apache::DBI and DBI and use Apache::DBI is before DBI. We actually
call DBI-connect_cached and based on DBI document, I guess this would be
handled by Apache::DBI connect.
Yes, it should be.
However, I guess we also defined a base class
Hi Perrin,
The query is from the application code not the 'select 1' test query.
While most of time I saw Apache::DBI-connect is called but sometime from a
process, it will print out it finds a cached connection and ping is ok but
sometimes from the same process it didn't find a cached

Have you used the DRCP settings in DBD::Oracle?

From the description of DRCP, it sounds like you should never lose the
connection. You may want to check the configuration.
From your debugging

The $ok is undef. In the case if the test does succeed (like the first

That all sounds good. 0E0 is a true value in Perl. It means zero but
true. And undef is a false value. You don't need

I don't actually understand why you did that. What was wrong with the normal

With Oracle DRCP, even though ping succeeds, the connection to the server
