Before you begin
Important: For best results, before you use your
Rational product, increase the number of file handles available for
Rational Build Forge. A system administrator might need to make this
change.
Exercise caution when you follow these steps to increase
the file descriptors on Linux. Failure to follow the
instructions might result in a computer that does not start correctly.
For the best results, have your system administrator perform this
procedure.
To increase the file descriptors:
Procedure
- Log in as root. If you do not have root access, you must
obtain it before you continue.
- Change to the etc directory.
- Locate the initscript shell script. Open the file or create
it with a Linux text editor.
Important: Do not
leave an empty initscript file on your computer. If you do so, your
computer will not start the next time that you turn it on or restart
it.
- On the first line, set ulimit to a number significantly
larger than 1024, the default on most Linux computers.
ulimit
-n 4096
Caution: Setting ulimit too high can
impact system-wide performance.
- On the second line, type eval exec "$4".
- Save and close the shell script.
Results
For more information on the ulimit command, refer to the man
page for ulimit.
