Ans: Oracle HTTP Server is installed and configured with
every middle-tier and Infrastructure installation.
You can access
Oracle HTTP Server as follows:
http://hostname.domain:port
port is the Oracle HTTP
Server Listen port number in:
ORACLE_HOME/install/portlist.ini
http://hostname.domain:7778

What is a Webcache?
Ans: OracleAS
Web Cache is a content-aware server accelerator, or reverse proxy server, that improves the performance,
scalability, and availability of Web sites that run on Oracle Application
Server. By storing frequently accessed URLs in memory,
OracleAS Web Cache eliminates the need to repeatedly process requests for those
URLs on the application Web server and database tiers. Unlike legacy proxies
that handle only static documents, OracleAS Web Cache caches both static and
dynamically generated content from one or more application Web servers.
Webcache sits in front and even serve the
purpose of a software load balancer.
What is a Farm?
Ans: The Farm home page displays a list of the standalone
application server instances and Oracle Application Server clusters associated
with your Infrastructure Services. Standalone instances are application server
instances that are not part of an Oracle Application Server cluster.
You
can configure your application server instance to use Infrastructure Services
by clicking Infrastructure on the Application Server home page. For more
information, see the Enterprise Manager online help.
Using the Farm home
page, you can perform the following tasks:
·
Manage
multiple application server instances on multiple hosts
·
Drill
down to the Application Server home page for each instance
·
Create
and manage Oracle Application Server clusters
Ans: The single sign-on server consists of program logic in the OracleAS
database, Oracle HTTP Server, and OC4J server that enables you to log in
securely to applications. These applications take two forms: partner
applications and external applications. In both cases, you gain access to
several applications by authenticating only once.
Mod_osso is an Oracle HTTP
Server module that provides authentication to OracleAS applications. Mod_osso
renders authentication transparent to OracleAS applications
What is OID?
Ans: Oracle Internet Directory is a general purpose directory
service that enables fast retrieval and centralized management of information
about dispersed users and network resources. It combines LDAP Version 3 with
the high performance, scalability, robustness, and availability of Oracle9i
Ans: Oracle
Application Server provides a complete Java 2 Enterprise Edition (J2EE)
environment written entirely in Java that executes on the Java virtual machine
(JVM) of the standard Java Development Kit (JDK). You can run Oracle
Application Server Containers for J2EE (OC4J) on the standard JDK that exists
on your operating system.
What is OPMN?
Ans: Oracle Process Manager and Notification Server (OPMN) manage
and monitor most Oracle Application Server components. It is installed and
configured in every middle-tier and Infrastructure installation and is
essential for running Oracle Application Server.
ORACLE_HOME/opmn/bin/opmnctl
status
Notice that the LogLoader process is always
down after installation. Log Loader is a feature that compiles log messages
from various log files into a single repository. If you wish you can start Log
Loader after installation.
What is Application
server control?
Ans: The primary tool for managing Oracle Application
Server--as well as your entire Oracle environment--is Oracle Enterprise
Manager. To manage Oracle Application Server, you use Oracle Enterprise Manager
Application Server Control. Application Server Control is installed with every
instance of Oracle Application Server. As a result, you can immediately begin managing
your application server and its components from your Web browser.
Display the Oracle
Application Server Control page by entering the following URL in your Web
browser:
http://hostname.domain:port
where default port
for firdt installed instance will be 1810.
Enterprise Manager
displays the administrator logon dialog box.
Enter the Oracle
Application Server administrator user name and password and click OK.
The user name for
the administrator user is ias_admin.
The password the
one you supplied during the installation of Oracle Application Server.

Who is Ias_admin?
Ans: Ias_admin is an administrator who has all the
privileges to administer an Instance.
At
the time of Installation for every Instance we give an Ias_admin password.
We need to enter this password for
Authentication purpose while using Application Server Control
What are variuous
methods to administer an Application server?
Ans: Oracle realizes that the procedures you use to monitor
and administer your application server components can vary, depending upon the
size of your organization, the number of administrators you employ, and the
types of components you manage. As a result, Oracle offers options for managing
your Oracle Application Server installations.

Ans:
If a host inside
a protected a LAN (Using private IP) wants to access the external web, he can access
through a server which has a public IP. The entire request from the user goes
to external world through this server. This server is called a proxy server.
In a similar
manner if an external host of web wants to request a server in a protected LAN
(using a private IP) then the request has to be picked up by a server which
belongs to the public Network and redirect it to the internal host. This server
is called a reverse proxy server.
Ans: Configuring the server (Located in private LAN) to
access from the external public domain is called reverse proxy configuration.
If we say that a
server is reverse proxy configured that
does mean we can access this server from web.
Ans: Please refer the following
document
P:\WSS\Study\Portal\Portal Configuration\PortalAdministration.pdf
5.6 Configuring Reverse Proxy Servers.
Ans: We have UAT box &
Prod box configured for reverse proxy.
Ans: Oracle
Wallet Manager is an application that wallet owners use to manage and edit the
security credentials in their Oracle wallets. A wallet is a password-protected
container that is used to store authentication and signing credentials,
including private keys, certificates, and trusted certificates needed by SSL.
You can use Oracle Wallet Manager to perform basic tasks such as creating
wallets, generating certificate requests, and opening wallets to access
PKI-based services.
Ans: Yes, ssl is configured on production system
Ans: The
purpose of a Load Balancer (LBR) is to provide a single published address to
the client tier, and front-end a farm of servers that actually service the
requests, based on the distribution of the requests done by the LBR. The LBR
itself is a very fast network device that can distribute Web requests to a
large number of physical servers.
Ans:
Load Balancer is of two types
- Hardware(fast network device that can
distribute Web requests)
- Software
( Webcache is used)
We are using a standalone webcache (Software Load
Balancer) in our production system.
