in reply to Perplexing error message with Oracle 10g Express Edition.

Did you search?

Which version of perl do you have?

Where did you install the binaries from?

Its a binary compatibility problem. Perl-5.8.x has broken compatibility a couple of times, and whomever created your DBI/Oracle binaries (ppd), did so with a perl which is not compatible with yours.

Offhand, compatibility was broken in 5.8.1, 5.8.7.

The solution is to reinstall a DBI and DBD::Oracle compatible with your version of perl, or upgrade your perl.

update: It appears this incompatibility are due to ActiveState's modifications (ActivePerl build 816).

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
