OracleAS 10g Sample Configuration
This is a diagram of a multiple-server OracleAS 10g configuration I've used for a Forms and Reports application:
Sample OracleAS 10g Configuration
Notes:
- The OracleAS 10g Middle Tier contains the Web Cache Oracle HTTP Server and the OC4J_BI_Forms instance.
- The OC4J_BI_Forms instance contains the Forms 90 servlet.
- The Web Cache is disabled in the secondary servers' middle-tiers to ensure a single-point of entry through the primary server's Web Cache.
- The Reports servers are stand-alone servers configured as Reports Server cluster repserv.
10g Web Cache Load Balancing
10g Web Cache Load Balancing
Update (2005.12.08)
While attending the Oracle Application Server 10g Administrator I course, the instructor related the Web Cache is NOT a true load-balancer. It distributes sessions to the middle-tiers in a round-robin fashion. A true load-balancer determines the least-loaded middle-tier and sends the session to it.
