This section describes the post-installation tasks for the J2EE applications that are part
of the Web Tier of an Enterprise Deployment Topology:
■ Oracle Application Server Web Cache
■ Oracle HTTP Server
■ Oracle Application Server Forms Services
■ Oracle Application Server Reports Services
■ Oracle Application Server Discoverer
■ Oracle Application Server Single Sign-On

2.6.1 Oracle Application Server Web Cache
Here is a post installation and configuration check list for OracleAS Web Cache.
1. Configure a Ping URL
For Watchdog to check the health status of Web Cache, the configurable URL
recommend being a cacheable. When a non-cacheable URL is configured, Web
Cache will try to connect to the origin server. If the origin server is not responding
with the time out from Watchdog, Watchdog will restart Web Cache.
2. Optimize connection limits
The Application Server (origin server) connection limit and the Inbound
Connection limit should be set to an optimum number.This number depends on
the volume of traffic from client requests from OracleAS Web Cache to the origin
server when it caches missed requests.
3. Physical memory
To reduce disk swapping with objects in the cache, install enough memory for the
cache. Oracle recommends a minimum of 256MB.
4. Set up apology pages (Network Error, Server Busy, and ESI Fragment)
The default apology pages for network error, Origin server busy and ESI fragment
may not match the format (look-and-feel) of the application.
5. Set up SSL Certificates
To set up the client side SSL certificate:
a. Create a new wallet with the Oracle Wallet manager
b. Specify the new wallet in the Listen Ports page (Ports -> Listen Ports) of the
OracleAS Web Cache Manager administrative interface.
To set up the origin server (OS) SSL certificate:
a. Create a new wallet with the Oracle Wallet manager
b. Specify the new wallet in the Origin Servers, Sites, and Load Balancing page
(Origin Servers, Sites, and Load Balancing -> Origin Server Wallet)
6. Set up Site Definitions (virtual hosting)
