Ports
2-8 Oracle Application Server Installation Guide
To view the current value specified for these kernel parameters, and to change them if
necessary, follow these steps:
1. Optionally, set the DISPLAY environment variable to specify the display of the
local system:
■
Bourne, Bash, or Korn shell:
$ DISPLAY=localhost:0.0 ; export DISPLAY
■
C shell:
$ setenv DISPLAY localhost:0.0
2. Start System Administration Manager (SAM):
# /usr/sbin/sam
3. Choose the Kernel Configuration area, then choose the Configurable Parameters
area.
4. Check the value or formula specified for each of these parameters and, if
necessary, modify that value or formula.
If necessary, see the SAM online help for more information on completing this
step.
5. Exit from SAM.
6. If you modified the value specified for any parameter, reboot the system:
# /sbin/shutdown -r now
7. If necessary, when the system restarts, log in and switch user to root.
2.5 Ports
Many Oracle Application Server components, such as Oracle HTTP Server, OracleAS
Web Cache, and Oracle Enterprise Manager 10g, use ports. You can have the installer
assign default port numbers, or use port numbers that you specify.
