Chapter 2: Server Tuning
These operating system settings can affect EAServer performance. For additional information on system requirements, see the EAServer Release Bulletin for your platform.
On UNIX, concurrent client connections to EAServer are limited by the operating system limit for the number of file descriptors that can be opened in one process. Before you start the server, set the file descriptor limit in the shell where you will start the server. For example, to set the limit to 1024:
Use a text editor to open the bin/serverstart.sh file.
Below the first comment block, add this line:
ulimit -n 1024
See your UNIX documentation for more details on the ulimit command.
On some systems, the default configuration limits the memory available to the server. You may need to raise the limit to make best use of memory intensive features such as caching or a large Java heap. For more information, see:
Your operating system documentation for details on per-process limits
