Introduction

Directives

Port number=default port, if no "listen" directives are present. Otherwise, if one or more "listen" directives are present, the server listens on the listening ports and not on the the port defined with "port". The port value is the default port for redirected URLs or other URLs generated by server. Normally, one of the listening directives has the same number as the default port. For web caches, set the port directive to the port for the Web Cache and set the listen directives to the ports to which HTTP Server is listening: the redirected URLs will point to Web Cache, rather than directly to Oracle HTTP Server.

Maximum requests Processed Simultaneously (maximum users): maximum number of child processes on UNIX (best: 150) or maximum number of threads on Windows.

MaxRequestsPerChild: maximum number of requests for one of the child processes. Not available for Windows. In Windows, a parent process launches one child process and each of the requests is handled by a thread. In UNIX, one parent process launches several child processes.

KeepAlive: time before a new request
Timeout: time out after request is first made.

MaxKeepAliveRequests: maximum number of requests per connection, 0--> unlimited.

Some Tips

ServerRoot ".../Apache"

No slash at end

Port 80

Under 1024, must be root

Listen n

For SSL

ServerAdmin

A real person's email address

ServerName

Valid DNS name

User

The user under which Apache will run (starts in root but switches over)

<IfModule mod_userdir.c>
UserDir a-directory
</ifModule>

Name of directory where user directories are defined

DocumentRoot ...Apache/htdocs

Start of all web pages

<IfModule mod_dir.c>
DirectoryIndex the_index_page.html another-default-page.html
</IfModule>

Default pages in the DocumentRoot

<Directory "D:\ORACLE\iSuites\Apache\Apache/htdocs">
Options MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>

Permissions on default directory

ErrorLog path/name

Main error log

LogLevel warn

Level of detail in error log

 

redirect /admin http://ServerName/new_url

Redirect requests

include "...Apache\Jserv\conf\jserv.conf"

Include other configuation files (at end of httpd.conf)

Redirect /namepath http://hostname:portnumber/pls/portal

Redirection

Rewrite

(Set "RewriteEngine On" in configuration for mod_rewrite)

RewriteRule OriginalPath RewrittenPath [flags]

Virtual Hosts

NameVirtualHost * --> name-based virtual hosting, i.e. the virtual host is defined by the name. Mandatory for SSL with 9iAS. IP-based virtual host means that a different IP address is needed for each virtual host.

<VirtualHost *>
  ServerName new-virtual-server-name
  DocumentRoot "...Apache/htdocs"
  ServerAdmin real.person@some.address.com
  <IfModule mod_dir.c>
    DirectoryIndex the_index_page.html another-default-page.html
  </IfModule>
  ErrorLog path/error.log
  CustomLog path/access.log
  ServerAlias ...com ...ch ...glu
</VirtualHost>

Use * instead of ip-address --> this is name-based virtual hosting
ServerAlias optional
If error and custom log indications are absent, then main server's logs are used.

Examples

Minimal configuration on Windows, but not as a service:

ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2"
Listen 8080
LoadModule .... a whole bunch
ServerName TestServer:8080
#Put this in the hosts file:
# 127.0.0.1 TestServer
#Enter this in the browser:
# http://TestServer:8080
#
DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs"

Tomcat

The Tomcat users are defined in: ...\conf\tomcat-users.xml
The passwords are unencrypted

Context files are located in: ...\conf\Catalina\localhost
Three contexts are defined by default: admin.xml, host-manager.xml , and manager.xml
