Hi,

I have many silent connection attempts from jdbc failing silently. There is no error caught by the java code. I am finding very little information on Metalink. Have opened a ticket, traced the listener, changed inbound connection timout on both listener and jdbc string to no avail.

The only thing I see in the alert log is this...
