Oracle Weblogic
Server

WebLogic Server 10.3
• Hardened release of the WebLogic 10.x release cycle
• Recommended WLS 8.1 and WLS 9.2 upgrade path
• Upgrade to mature release, fully compliant with Oracle
requirements
• Foundation release of Fusion Middleware 11 R1
• Fusion Middleware 11 R1 will do small incremental
maintenance changes to core WebLogic Server

Architectural View: Domain
• What is it?
• a logically related group of WebLogic
Server instances that you manage
from a single set of configuration
artifacts.
• What’s in a domain?
• Servers
• Clusters of servers
• Rules:
• All WebLogic Server instances within
the same domain must be at the
same major and minor version.
• Servers within a domain can be at
different Maintenance Pack levels as config.xml
long as the Administration Server is
at the same Maintenance Pack Level
or higher than its Managed Servers.

Architectural View: Administration Server
• What is it?
• Central configuration controller for the entire Managed Servers
domain
• What else does it do?
• Hosts the Administration Console
• Enables you to start and stop servers from a Admin Server
central location
• Enables you to migrate servers and services within
the domain config.xml
• Enables you to deploy applications within the
domain
• Guidelines:
• There must be exactly one* Administration Server
in domain
• An Administration Server controls only one domain.
• For production use, we recommend not hosting
application logic or resources on the Administration
Server
Admin Console
*The Administration Server does not need to run at all times, but is required for making
configuration and deployment changes to a running domain.

Architectural View: Node Manager
• Utility/process running on a physical server
that enables you to start, stop, suspend, and
restart WebLogic Server instances remotely
• Must run on each physical server that hosts
WebLogic Server instances that you want to
control with Node Manager
• Not associated with a domain. Can start any
server instance that resides on the same
physical server.
• Optional, but required to start/stop servers
using the Administration Console
• Required for Whole Server Migration and for
some configurations of Automatic Service
Migration Admin Server
Managed Server
Node Manager

Architectural View: Big Picture

Lightweight WebLogic Server
• Lightweight installers
• “Core” WLS install option, add­ons (JDKs, etc) optional
• Reduce download and install time, installation footprint
• Optional service startup
• Start WebApp container without starting EJB, JMS, JCA
services
• Provide developer flexibility

Production Redeployment
Side by Side Deployment
• Multiple application versions can co­
exist
• New client requests are routed to active
version; Existing client
requests can finish up with existing
version
• Automatic Retirement Policy: Graceful,
Timeout
• Test application version before opening
up for business
• Rollback to previous application version
• Two versions of the application can be
active at any given point of time

Integration with Oracle RAC
Oracle RAC Support
Use WLS Multi­Data­Sources
• Fast failover upon node failure
• Load­balancing or Failover
algorithm
• Periodic health check of
connections

High­Value and Unique features
Best­of­Breed Messaging (JMS) Engine
• Unit of Order/Unit of Work
• Strict Ordering of Message processing
• Distributed Destinations
• Highly Available JMS Destinations across a Cluster
• Store­and­Forward (SAF)/Client SAF
• Asynchronous Reliable Messaging across WAN
• Integrated JTA (XA) Transaction Management

Self­Tuning and Work Managers
WebLogic's Self­Tuning Thread Pool
Network Socket Handlers
(“Muxers”)
Self Tuning • Active
Thread Pool • Standby
• Stuck
• Hogging
Request Queue
Asynchronously dispatched work 1. Monitor rate of
from WebLogic kernel, subsystem request processing
or application
2. Adjust thread pool
size accordingly

Self­Tuning and Work Managers
Configurable Work Managers
• Every application has its own Work Manager
• based on the 'global' 'fair­share' work manager by default
• Can explicitly configure a new Work Manager
• apply to one or more specific applications and even individual resources
• Each work manager can have a mix of the following
configuration elements....
REQUEST CLASS ELEMENT CONSTRAINT ELEMENT TRIGGER ELEMENT
• Fair Share (default) • Minimum Threads (active) • Shut­down Trigger
• Response Time (goal) • Maximum Threads
• Context based (per • Capacity (threshold for
user/group) rejection)

Clustering and High Availability
Transparent Load Balancing and Failover
HTTP, EJB, JNDI and JMS clients
• HTTP requires Hardware Load Balancer or Web Server Proxy
• EJB/JNDI/JMS client 'stubs' are automatically cluster aware

Quality of Service
Meet the Most Demanding Requirements for “RASP”
• Reliability
• Proven quality in enterprise environments – “it just works”
• Transactional integrity, reliable messaging, Oracle RAC
• Availability
• Maintain app/service availability to end users
• Tolerate planned and unplanned events
• Scalability
• Expand and add system resources as required
• Millions of users and thousands of systems
• Performance
• Aggregate throughput of apps/services
• Low, predictable latency

Oracle Coherence
Distributed Data
Grid

Oracle Coherence Data Grid
Distributed in Memory Data Management
Enterprise Real Time Web
Applications Clients Services
• Provides a reliable data tier
Data Services
with a single, consistent view of
data
Oracle Coherence • Enables dynamic data
Data Grid
partitioning including fault
tolerance and load balancing
• Ensures that data capacity
scales with processing
Databases Mainframes Web Services capacity

The Coherence Approach…
• Traditional scale­out approaches limit
• Scalability, Availability, Reliability and Performance
• In Coherence…
• Servers share responsibilities (health, services, data…)
• No SPoB
• No SPoF
• Massively scalable by design
• Logically servers form a “mesh”
• No Masters / Slaves etc.
• Members work together as a team
