An ongoing problem, Upgrading to 1.14 my solve you problem but I cannot say for sure I am not familiar with the earlier code. You may find upgrading your Oracle client may fix it as well. By the way what version of Oracle and Oracle client are you using? Finally you would be much better off posting your question to dbi-users@perl.org, you don't need to subscribe in order to post, and you won't be automatically subscribed eitherr, as very few people use this form for dbi or driver support. dbi-users is where you'll get the best support
