7. Load Balancing Distributes load among different hosts
Load balancing relevant for multi-node installs ONLY
Base edition: same as 3.0
round-robin scheduling among instances based on user-defined parameters
Advanced edition
Node weighting
System-adaptive

8. Node Weighting
Administrator distributes load among cartridge server machines by assigning weights
Stride Scheduling algorithm with node weights used to assign requests to machines
Seamlessly adapts to adding hosts at runtime
Node 1
25%
Broker
Node 2
50%
Node 3
25%

9. Node Weighting Example
Host weights: 0.25, 0.35, 0.4
Stride values: 40, 28, 25

10. Reliable Process isolation Automatic software failure recovery
No single point of failure

The improvements planned include upgrading the ORB to be CORBA 2.0 compliant. In addition, for the first time this ORB will be exposed to developers. This will allow developers to build true CORBA components. These components will be hosted by the ORB and interface to the ORB via IDL (Interface Definition Language).
Exposing the ORB does not mean that “Web Cartridges” or the WRB API will disappear. This API, with only four calls, allows quick and easy development of components.
Interfacing directly with the ORB, while more complex, allows creation of standard CORBA components which interface via standard IDL.
OAS 3.1 will also include support for CORBA compliant services like Object Transaction Service and Naming. Directory services (standards-based though not CORBA-based) are also supported.These will be discussed in more detail in a moment.
In addition, OAS 3.1 supports connections to the ORB from other ORBs via standard IIOP (Internet Inter-ORB Protocol). IIOP is how application servers (whether from Oracle or other vendors like IBM, Sun or Netscape) will achieve base-level interoperability.
In addition, client use of the next generation of Netscape Navigator which includes an ORB(let) in the browser itself will allow the client to communicate with the server via standard IIOP. Microsoft, by trying to differentiate its browser technology from the rest of the industry will limit Internet Explorer’s ability to interface with cross-platform servers from every other vendor in the industry.

13. HTTP Listener Integration
CORBA 2.0 ORB
HTTP Servers handle requests for static pages and CGI on their own
Dispatcher is linked into HTTP Server using portable ADP (API Adapter) layer
ADP layer interfaces directly with native API of HTTP server: NSAPI, ISAPI, ADI, ...
IDL
Dispatcher
ADP Layer
HTTP Server
This how the integration works:
We use ADP layer which interfaces directly with web server API
Any incoming request which can be handle by web server itself such as static web page will be handle with Application server intervention.
Whenever URL is not recognized by web server it will be pass to Oracle’s WRB which will then take care of executing correct component.
You can integrate your existing web sites with Oracle Application Server fast and easy. You don’t have to make any changes to your existing web pages
Network interface for Applications
Insulate application logic from network protocols
Enables heterogeneous application development
Netscape, Microsoft, Apache, Spyglass

14. Application Server Services
Provide common set of services across applications
Extensible: add new services as they become available
Core services: management, load balancing, security
Web services: ICX, X/A, Content
CORBA services: OTS
There is a wide range of services available from Application Server which can simplify the process of developing your own applications
management of cartridges, load balancing , security
but also transaction processing services for the cartridges and CORBA objects
There is ICX inter cartridge exchange service which allows different cartridges to communicate with each other
we have content cartridge which allows you to store data in Oracle’s database

15. Security Authentication Providers
Authentication Server manages mapping of authentication requests and
Pre-built Authentication Providers
Digital ID Authentication
SSL X509V3
LDAP IP
Domain
Basic
RDBMS
Security services allow you to use different authentication schemes with OAS
We can use basic authentication using user name / password combination
Authentication based on IP address or DOMAIN name
Finally you integrate your authentication with Oracle’s database user
and with 4.0 we introduced support for LDAP directory authentication including support for digital services compliant with X509.V3 standard

16. Enterprise Transactions
Web Xactions
X/Open TX & XA
TXAPI
Zero Code
Object Xactions
CORBA OTS
Java JTS
Oracle7
Oracle8
Any XA
Resource
Manager
One of the most important services which are built-in into our architecture is transaction processing
We support transaction processing for web cartridges using X/Open and XA standard
but also we have TX exposed to your cartridges through WRB API
finally there is support for Zero Code transaction processing using demarcation marks based on your URL . For example: you can use it with your PL/SQL application and process transaction through multiple web pages without writing a single line of code as long as you define begin tansaction URL, all the URLs which belong to this transaction and finally URLs which should trigger rollback or commit functions.
We also have support for transactions for you JAVA and CORBA applications
