What does Oracle error “ORA-17432: invalid options in all7” mean?

This is almost certainly not something you're going to have control of. It looks like a problem with the way your thin driver is using the two-task common (TTC) protocol. One thing to note is that this sort of thing can be very sensitive to the version of the driver you are using.

Make absolutely certain that you have the latest version of the JDBC driver for the combination of the version of Java you're using and the version of Oracle on the server.

Akohchi - you were in the right area though not quite correct. The explanation obtained via Oracle Support call was that this version of Java (1.3) was not compatible with new Oracle. Java 1.4 fixed the issue.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
