UNIX Settings
If installing on UNIX note that Windchill requires the following:
An X Windows session capable of displaying xterm
The xterm application needs to be installed
* 
During Windchill installation on the UNIX system, ensure that the shell limits for the maximum number of open file descriptors is set to a minimum of 4096. Consult the operating system documentation or system administrator to determine how to do this in your environment.
When installing on UNIX systems, the umask value must be checked prior to running PSI. The umask must be set so that newly created files are writable. One possible umask value that might work is 022. If you are unsure what value is appropriate for your site, talk to your system administrator.
