Get a 10046 trace of the process. This will tell you exactly what the
DB is waiting for.
I have had no issues with the TNS listener to date.l

I plan on using Sys::SigAction to wrap an alarm around the connect, but
I thought I would post to see if anyone else has seen this problem. I
have
a process that runs in cron every 2 minutes, it processes files that are
ftp'd
into our site. I set a lock file so that if the previous run is still
running
it will not start up and send an email indicating that a previous
process is still
running. Well we moved to this processing was moved to a new server
which is running
Oracle version 10.2.0.1.0. I've been having a problem where this
process is hanging
for serveral hours (occurs over night) until it is killed. I run an
strace on the pid
and it is hanging on a read of fd 6, which is the Oracle tns listener.
I don't believe
any thing has processed, because there are no raised errors. I think
that it has to be
hanging on the connect, since I believe the tns listener accepts a
connection and then
gives the connect process a direct socket to Oracle. As I stated
earlier, I was
wondering if anyone else on the list has problems with 10g tns listener?
