Installing and Configuring on Unix
Specifies the maximum number of open files supported. If the value of this parameter is too
low, a Too many files open error is displayed.
How to view or set:
Use the following command to display the current settings.
ulimit -a
Use the following command to set the values
ulimit -n 8192
Check the UNIX reference pages on the ulimit command for the syntax of different shells.
Recommended value: 8192
Note:
On Solaris, setting the maximum number of open files property using ulimit has the
biggest impact on your efforts to support the maximum number of RMI/IIOP clients.
To increase the hard limit, add the following command to /etc/system and reboot it
once:
set rlim_fd_max = 8192
Solaris TCP_TIME_WAIT_INTERVAL
Description:
Notifies TCP/IP on how long to keep the connection control blocks closed. After the
applications complete the TCP/IP connection, the control blocks are kept for the specified time.
When high connection rates occur, a large backlog of the TCP/IP connections accumulate and
can slow server performance. The server can stall during certain peak periods. If the server
stalls, the netstat command shows that many of the sockets that are opened to the HTTP
server are in the CLOSE_WAIT or FIN_WAIT_2 state. Visible delays can occur for up to four
minutes, during which time the server does not send any responses, but CPU utilization stays
high, with all of the activities in system processes.
How to view or set:
Use the get command to determine the current interval and the set command to specify an
interval.
For example:
ndd -get /dev/tcp tcp_time_wait_interval
