I would say use 1.24 or the trunk version
http://theoryx5.uwinnipeg.ca/pub/CPAN/authors/id/P/PY/PYTHIAN/DBD-Oracle-1.24.tar.gz
there may be a problem with that file so you might want to try here as well
http://svn.perl.org/modules/dbd-oracle/trunk
There is some new majik in 1.24 that will speed up any queries you do by
a few orders of magnitude ;).

I was using DBD::Oracle 1.20 in development, and DBD::Oracle 1.21 in
integration, test and production. So far we have only deployed DBD::Oracle to
development. Would you recommend to install something else for integration,
test and production?
We had DBI 1.602 in development, and we were having trouble installing
DBD::Oracle 1.23, so we upgraded to DBI 1.609 and that seemed to fix the
problem.
What DBI and DBD::Oracle do you recommend for production use?
John

The bug in 1.23 will hit you if you try to an insert more than one CLOB
at a time.
If you are not inserting CLOBs then do not worry about it.

DBD::Oracle 1.22 instead? What I the nature of the bug?
I am fairly new to the dbi-users group, and I haven't been watching the emails.

Hard to say what is going on here but me things you are running into the
'ping' problem
Are you using Apache::DBI??
Many of these warehouse applictions reuse the same connection handel and
to keep them alive they use $dbh->ping which runs a query to maintain
the connection.
What version of DBD::Oracle are you using?
If you can upgrade to DBD::Oracle 1.22 (do not use 1.23 there is a bug
in there that might be worse) or get the latest 1.24 version
that might solve your problem

I'm a dba supporting a warehouse database (production environment)
accessed via a custom application built on open source components, one of
which is dbd::oracle.
Performance monitoring shows two queries continually consuming
considerable resources (cpu waits) - the query text resembling for the
most part 'column_info' and 'table_info'. Over any given day, the
column_info select is executed +260 times an hour, 'table_info' executed
+360 times an hour.
Is this level of frequency intended? And are these calls appropriate
(expected) for a static data dictionary environment?
Any response that would help my understanding would be appreciated.
Thanks.
