Ayhan, **Thank you** Actually, my drivers were compiled against 8.1.6.1 (on Linux) too, and I'm communicating with an Oracle 7.3.3 database (on a separate Solaris box). Could that be part of the problem? I don't think there was an Oracle 7 for Linux. Are there some settings I could change to make my drivers more "Oracle 7 compatible" ?

Look for a file named 'sqlnet.log' on your system. If Oracle is the culprit, this file can help you understand what its problem is.

Your database may be rock solid but it may not be true for your drivers. Last time I compiled, I used latest ZOracleDA with latest DCOracle (not the one that came with ZOracleDA) and the whole thing has been solid for months.

PS: I'm not sending my drivers since they were compiled against Oracle 8.1.6.1
