Hi,
Thanks for the help. Can anyone please recommend me a initial value for the
ulimit -n, currently it is set to default (1024). I guess this should not be
the value for a production server. Can someone please suggest me a ulimit -n
for a production glassfish server.
Thanks in Advance,
Regards,
Lasitha

I believe ulimit, with no arguments, reports the file size limit.
You would want ulimit -n to see the limit on the number of file descriptors
that can be open at one time.
While this following link is for the directory server, it does run through
how to increase the number of file descriptors on a Redhat 4 system:
http://www.redhat.com/docs/manuals/dir-server/install/8.0/Installation_Guide
-Support-Platforms.html#Installation_Guide-Platform_Support-File_Tuning
which might help.

Hi All,
In our production server the following error occurs. We are having a 1
instance GF cluster. We are starting the server using root and when I check
the ulimit of the machine, it says unlimited. We are using Red Hat AS 4
Update 2 as the OS.
"
[root_at_mimax ~]# ulimit
Unlimited
"
Please help me to solve this problem.
Regards,
Lasitha
