Re: Memory corruption with Perl (DBD::Oracle)

Thanks for your feedback, we're going to install the preconised patchsets on our 11.1.0.6 client.

What about the warning of compilation BDB-Oracle?
WARNING: Unable to interpret Oracle build commands from /app/oracle/product/11.1.0/client_1/rdbms/demo/demo_rdbms32.mk.
(Will continue by using fallback approach.)

Regards.
