Sun Java System Web Server 6.1 SP9 Performance Tuning, Sizing, and Scaling Guide

File Descriptor Limits

Append the following line to the file /etc/system to increase the number of file descriptors for Sun Java System Web Server:

set rlim_fd_max=65536

After making this or any change in the /etc/system file, reboot Solaris to put the new settings into effect. In addition, if you upgrade to a new version of Solaris, any line added to /etc/system should be removed and added again only after verifying that it is still valid.
