What are the OracleAS
infrastructure components?
The OracleAS infrastructure
components are grouped into two categories:
Identity Management
components: it contains schemas for components such as Portal
and Wireless
OracleAS Metadata
Repository components: It is a consistent security model for all
applications. It contains:
a) Oracle Internet
Directory
b) OracleAS Delegated
Administration Services
c) Oracle Directory
Integration and Provisioning
d) OracleAS Certificate
authority.
Oracle Application Server
Topology
Client tier: PC,
Cell phone, or PDA
Middle tier: HOST1-
J2EE and WebCache, HOST2- Portal and wireless, HOST3- Portal and
wireless, HOST4- BI Business Intelligence and forms, HOST5- etc.
Infrastructure: HOSTn-
Single Sign On and OID, HOSTm- Metadata repository.
What is Oracle HTTP Server?
Oracle HTTP Server or OHS
is an extension of the standard Apache distribution. It provides a
robust and reliable Web server. You can access to FORMS, REPORTS,
Discoverer, and Portal via the Web. You can access to Oracle stored
procedures with a PL/SQL engine. It provides failover and supports
J2EE (OC4J).
How to start and stop the
HTTP Server manually:
The Oracle HTTP Server –OHS-
is managed by the OPMN utility.
# cd $ORACLE_HOME/opmn/bin
# ./opmnctl startproc
process-type=HTTP_Server -- starts the process
# ./opmnctl stopproc
process-type=HTTP_Server -- stops the process
# ./opmnctl status –
gives status information
List the name of all Oracle
HTTP Server configuration files.
-
httpd.conf
-
mod_oc4j.conf
-
mime.types jsev.conf
-
oracle_appache.conf
-
aqxml.conf
-
moddav.conf
-
plsql.conf
-
ojsp.conf
-
xml.conf
How do you allow access
from specific IP addresses or machine name?
Change your httpd.conf file
to add the following lines:
<Location
/server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from xxx.xxx.xxx.xxx
</Location>
Configuring Directives and
Virtual Hosts
What is directive?
Directives are files to use
for configuring the server. For example, the web master of an Oracle
HTTP Server contains more than 120 directives at his or her disposal
for configuring the server. It contains container directives. The
containers have opening and closing tag. Any directive that doesn’t
appear within a container applies to the entire serve.
What is the
<Directory> directive and how do you maintain it?
It is a group of directives
that apply to the named directory and subdirectories.
Examples of how to maintain
the <Directory> directive:
<Directory /> --
refers to the whole file system.
Options none
AllowOverride none
</Directory>
<Directory /home/myfiles/*>
--refers to the myfiles subdirectory under home.
AllowOverride none
</Directory>
<DirectoryMatch “/u0[1-6]/”>
--refers to directories that start with u0 and end with a number from
1 to 6
AllowOverride none
</Directory>
How to use IP-Based or
Name-Based Virtual Hosts?
<VirtualHost
200.200.200.2 200.200.200.3>
DocumentRoot /usr/virtual/htdocs/home
ServerName www.iselfschooling.com
</>
ErrorLog /usr/virtual/logs/error_log
</VirtualHost>
<VirtualHost
www.iselfschooling.com>
DocumentRoot /usr/virtual/htdocs/home
ServerName www.iselfschooling.com
</>
ErrorLog /usr/virtual/logs/error_log
</VirtualHost>
