I am getting the following error, but the weird thing is that it happens on some machines only (always the sameones)

Here is the connection string

[Pinturiccio]

According to your connection string, you use direct mode to connect to database. If your port is not 1521, than you have to set the Port parameter in your connection string.

OracleScript.CommandTimeout = 30 by default. Try using OracleScript.CommandTimeout = 0 and notify us about results. Looking forward to your reply.

Setting the commandTimeOut=0 worked fine.
Thanks a lot
