Maintenance and Troubleshooting
Apache
Apache is a freeware web server developed by the Apache Software Foundation
(http://www.apache.org).
Apache is the most widely used web server on the Web. It has
excellent performance, is lightweight, stable, and very reliable. It should require almost no
maintenance from a system administration perspective.
Apache must be started by root. If you use the standard version of Apache distributed with
the operating system, then the requisite commands to start/stop Apache on system
boot/shutdown will already be configured: see /etc/init.d/httpd. Apache will start
automatically at boot time, provided httpd.conf exists and is correctly configured in
/etc/httpd/conf.
To check Apache is running:
prompt> ps –ef | grep httpd
If no processes are found restart Apache manually (as root):
prompt> /usr/sbin/apachectl stop
prompt> /usr/sbin/apachectl start
If Apache is not running, and cannot be restarted, check the error log file:
prompt> tail /etc/httpd/logs/error_log
WOW Browser
Due to Apache’s reliability, most errors are WOW errors and appear as an ‘Internal
Server Error’ in the browser. The Apache log file provides an excellent diagnostic
medium. If a repeatable error occurs in some part of WOW, do the following:
1. On the WOW top bar, click on Errors. This will display the Apache error log contents,
as well as the complete environment and WOW version number.
2. Click Write START tag, repeat the operation, click Write END tag.
3. Save this page and provide the output to your support representative for diagnosis.
WOW Command-line and GUI Utilities
The equivalent to the Errors link for non-browser utilities is the command-line wow_err
script:
prompt> source $OWHOME/WebApps/templates/wow.login
(if C-shell)
prompt> . $OWHOME/WebApps/templates/wow.profile (if Bourne shell)
prompt> wow_err
