Maximum open files

 

If the system is heavily loaded, you might need to increase the maximum possible number of open files. If your distribution supports the proc filesystem you can do this by issuing the following command:

  echo 32768 > /proc/sys/fs/file-max If you are using a pluggable security module such as PAM (Pluggable Authentication Module), ensure that this does not unduly restrict the number of open files for the 'mqm' user. For a standard WebSphere MQ queue manager, set the 'nofile' value to 10240 or more for the 'mqm' user. We suggest you add this command to a startup script in /etc/rc.d/...
