Got a minus one from a read call.

Question

I connect to a database with read only access using SQL developer. It's a TNS connection. I use a tnsnames.ora, forwarding port script and SQL Developer.

In the past, occasionally, when connecting, I get a error message Got a minus one from a read call. Vendor Code 0

If I do a reboot, it goes away. Another friend suggested changed the forwarding port which worked for him.

I recently upgraded to a new computer and now it seems that I am getting the error message consistently. Reboot or changing forwarding port does not help at all.

The port forwarding script contains something like this

putty -L (port):(machine name):1521

Does anybody have any idea? Thanks.

Answer 1

My port forwarding script forwards multiple ports. Somehow separating them into 2 smaller file, this error went away.
