# cd /stand/build
# /usr/lbin/sysadm/system_prep -s system
post a copy of the system file that gets generated.

Re: Problem with number of connections.
-- npty = 120
-- nstrpty = 60
I will try to post the remaining parameters however I was having difficulty with the command posted. I did exactly as requested, and it just returns back with no errors. What am I doing wrong.?

Re: Problem with number of connections.
# cd /stand/build
# /usr/lbin/sysadm/system_prep -s system
# vi system (Make changes the values of 'npty' and 'nstrpty' say at least 500 for each)
save the file
# /usr/sbin/mk_kernel -s system
# mv /stand/vmunix /stand/vmunix_prev
# mv /stand/build/vmunix_test /stand/vmunix
# cd /
Reboot you system
# shutdown -r -y 0
If you are in any way uncomfortable, use 'sam'

Re: Problem with number of connections.
As far as TCP is concerned, so long as there is memory enough to hold the connections, it will allow them.
Now, given that a TCP connection is accessed via a socket, and a socket is a file descriptor, the per-process and system-wide limits on the number of open file descriptors does provide an upper bound .

Re: Problem with number of connections.
how about your Oracle instance's parameters?
- is "processes" big enough?
- do you have sufficient "semmns"? (Ok, that's another kernel parameter)
- do you have enough "dml_locks"?
FWIW,
Wodisch

Re: Problem with number of connections.
Have you checked the /var/adm/syslog/syslog.log file for any error msgs when the "ceiling" is hit?
I'm wondering if you don't have the maxuprc (kernel parm) set high enough & you're topping out on it.
This parm defines how many total processes can be spawned under a single user name - like oracle or whatever your oracle username is.
Oracle's a rabbit & wants to spawn lots of processes. If it's in the triple digits as a value - bump it up to several K at least.
HTH,
Jeff

Re: Problem with number of connections.
I am not sure whether you are running the database is the shared mode.
Check your $ORACLE_HOME/dbs/init
Do you have somtthing like
max_sessions
or
#mts_dispatchers
to some specific value.
Thanks

Re: Problem with number of connections.
may need to rebuild the special device file by issue: insf -d ptys -n 512 (or whatever)
insf -d ptym -n 512
