Does it actually break after N connections ? I've seen this occuring in the OLD days of oracle 7.1.6 wit OCI programs that repeatedly connected/diconnected.

Why don't you use the newest ORACLE ODBC drivers instead of Micro$oft ? You could use the new features of the database and maybe fix the problem at the same time. Received on Fri Apr 23 2004 - 21:11:21 CEST
