Understanding Oracle Fusion Middleware
ldquoOracle Fusion Middlewarerdquo is a misleading term
Used to describe middleware products such as
Business Intelligence (eg OBIEE Discoverer)
Integration (eg SOA Suite OSB)
Web Center (Web Center Content and Portal)
Identity Management (eg Oracle Access Manager)
Monitoring (eg OEM Grid Control)
But usually used to describe a single product

Oracle WebLogic Server
Java Enterprise Edition (Java EE) Application server
Acquired from BEA in 2008
Replaced Oracle Application Server
Required for almost all Oracle Fusion Middleware products
Supports the deployment of many distributed applications
Provides a standard set of APIs for creating distributed Java
applications that can access a wide variety of services such as
JMS JDBC RMI Web Services XML EJB etc

WebLogic Terminology
copy Raastech Inc 2015 | All rights reserved Slide 11 of 40Raastech
Domain
Logically related group of WebLogic Server instances that can be managed from a single set of configuration files
Domain Consists of
Servers
Clusters of servers
Each Domain requires an Administration server
All managed servers in a cluster must be part of same domain
Domain can spread across many machines but the WebLogic version has to be the same
copy Raastech Inc 2015 | All rights reserved Slide 12 of 40Raastech
Server
What is it
A configured instance to host applications and resources
WebApps Enterprise Apps Web Services hellip
JMS JDBC Diagnostics hellip
What types of servers are there
Administration Server
Managed Server
JNDI
JMS Queue
JDBC Pool
copy Raastech Inc 2015 | All rights reserved Slide 13 of 40Raastech
Administration Server
Controls configuration for the domain
Only one Admin server per domain
Admin Server can only control one domain
Hosts the Administration Console
Enables you to start and stop servers from a central location
Enables you to migrate servers and services within the domain
Enables you to deploy applications within the domain
It can be used as a managed server for lower environments
Admin Server
Managed Servers

Admin Console
copy Raastech Inc 2015 | All rights reserved Slide 14 of 40Raastech
Managed Server Managed Servers host business applications application
components Web services and their associated resources
Each Managed Server can function independent of other
Managed Servers in the domain
Managed servers do not share resources such JDBC JMS
and connection factories
No restrictions on the number of managed servers in a
domain
Can be cloned or added dynamically through the
administration console
Individual Managed Servers are typically added for
capacity and application isolation
Each Managed server stores a local copy of its
configuration
JNDI
JMS Queue
JDBC Pool
copy Raastech Inc 2015 | All rights reserved Slide 15 of 40Raastech
Cluster A cluster is a group of Managed Servers running
simultaneously and working together to provide increased scalability and reliability
Scalability through parallelism
ReliabilityAvailability through replication and redundancy
A Cluster is part of a single domain and each domain can contain multiple clusters
Domain can contain clustered and non-clustered managed servers
A cluster appears as a single instance to most clients
Clusters enable some advanced features such as Whole Server Migration Service Migration and clustered JMS destinations
Cluster 1
Cluster 2

Load Balancing in a Cluster
For JSPs and Servlets load balancing is external
Web server proxy plug-in (round robin)
HTTP Proxy servlet (ie using WLS as a load balancer)
3rd party hw or sw load balancer (F5 Big IP LTM or Cisco CSM)
EJBs and RMI Objects load balancing is done at connection
Objects are cluster-aware
Load balancing algorithm is stored in the clustered objectrsquos stub
Objects are available on all cluster members remote objects connectuse according the LB algorithm in the stub
Load balancing algorithms Round robin weighted random server affinity
copy Raastech Inc 2015 | All rights reserved Slide 17 of 40Raastech
Failover in a Cluster
Servlets and JSPs
HTTP session state is replicated to a secondary server in the cluster
or to a database
EJBs and RMI Objects
Replicas available throughout the cluster
Exceptions caught and retried on another instance
For Stateful Session Beans state is replicated on a secondary server
copy Raastech Inc 2015 | All rights reserved Slide 18 of 40Raastech
Communication in a Cluster
Peer to Peer using Sockets - used for
Accessing non-clustered objects deployed to another clustered server instance on a different machine
Replicating HTTP session states and stateful session EJB states between a primary and secondary server instance
Accessing clustered objects that reside on a remote server instance
Peer to Peer using Unicast or Multicast - used for
Cluster-wide JNDI updates
Heartbeats
Cluster-wide JNDI tree
Lists local resources and resources available throughout the cluster
List is maintained on all servers in the cluster
copy Raastech Inc 2015 | All rights reserved Slide 19 of 40Raastech
Node Manager
Process running on a physical server that enables you to start stop suspend and restart WebLogicServer instances remotely
Runs on each physical server that hosts WebLogicServer instances
Not associated with a domain Can start any server instance that resides on the same physical server
Node Manager is Optional but required to startstop servers using the Administration Console
Required for Whole Server Migration and for some configurations of Automatic Service Migration
copy Raastech Inc 2015 | All rights reserved Slide 20 of 40Raastech
Machine
A definition that identifies a particular physical piece of hardware
A machine definition is used to associate a computer with the
Managed Servers it hosts
Used by Node Manager in restarting a failed Managed Server
Used by a clustered Managed Server in selecting the best location
for storing replicated session data

Two-Phase Configuration Changes
Changes activated in batches
Reliability consistency
Make (related) changes as a group
Validate before making the change
Activate or Roll back as a single unit (all changes on all servers)
General process
Get an edit lock
make changes
changes are stored in the pending directory
activate your changes (with implicit validation through the Admin Console or WLST)
changes are distributed to servers in the domain
Two phases prepare and commit
Prepared on all servers any failures will cause total rollback

Domain
Logically related group of WebLogic Server instances that can be managed from a single set of configuration files
Domain Consists of
Servers
Clusters of servers
Each Domain requires an Administration server
All managed servers in a cluster must be part of same domain
Domain can spread across many machines but the WebLogic version has to be the same

Administration Server
Controls configuration for the domain
Only one Admin server per domain
Admin Server can only control one domain
Hosts the Administration Console
Enables you to start and stop servers from a central location
Enables you to migrate servers and services within the domain
Enables you to deploy applications within the domain
It can be used as a managed server for lower environments

Managed Server Managed Servers host business applications application
components Web services and their associated resources
Each Managed Server can function independent of other
Managed Servers in the domain
Managed servers do not share resources such JDBC JMS
and connection factories
No restrictions on the number of managed servers in a
domain
Can be cloned or added dynamically through the
administration console
Individual Managed Servers are typically added for
capacity and application isolation
Each Managed server stores a local copy of its
configuration
JNDI
JMS Queue

copy Raastech Inc 2015 | All rights reserved Slide 15 of 40Raastech
Cluster A cluster is a group of Managed Servers running
simultaneously and working together to provide increased scalability and reliability
Scalability through parallelism
ReliabilityAvailability through replication and redundancy
A Cluster is part of a single domain and each domain can contain multiple clusters
Domain can contain clustered and non-clustered managed servers
A cluster appears as a single instance to most clients
Clusters enable some advanced features such as Whole Server Migration Service Migration and clustered JMS destinations

Load Balancing in a Cluster
For JSPs and Servlets load balancing is external
Web server proxy plug-in (round robin)
HTTP Proxy servlet (ie using WLS as a load balancer)
3rd party hw or sw load balancer (F5 Big IP LTM or Cisco CSM)
EJBs and RMI Objects load balancing is done at connection
Objects are cluster-aware
Load balancing algorithm is stored in the clustered objectrsquos stub
Objects are available on all cluster members remote objects connectuse according the LB algorithm in the stub
Load balancing algorithms Round robin weighted random server affinity
copy Raastech Inc 2015 | All rights reserved Slide 17 of 40Raastech
Failover in a Cluster
Servlets and JSPs
HTTP session state is replicated to a secondary server in the cluster
or to a database
EJBs and RMI Objects
Replicas available throughout the cluster
Exceptions caught and retried on another instance
For Stateful Session Beans state is replicated on a secondary server
copy Raastech Inc 2015 | All rights reserved Slide 18 of 40Raastech
Communication in a Cluster
Peer to Peer using Sockets - used for
Accessing non-clustered objects deployed to another clustered server instance on a different machine
Replicating HTTP session states and stateful session EJB states between a primary and secondary server instance
Accessing clustered objects that reside on a remote server instance
Peer to Peer using Unicast or Multicast - used for
Cluster-wide JNDI updates
Heartbeats
Cluster-wide JNDI tree
Lists local resources and resources available throughout the cluster
List is maintained on all servers in the cluster
copy Raastech Inc 2015 | All rights reserved Slide 19 of 40Raastech
Node Manager
Process running on a physical server that enables you to start stop suspend and restart WebLogicServer instances remotely
Runs on each physical server that hosts WebLogicServer instances
Not associated with a domain Can start any server instance that resides on the same physical server
Node Manager is Optional but required to startstop servers using the Administration Console
Required for Whole Server Migration and for some configurations of Automatic Service Migration
copy Raastech Inc 2015 | All rights reserved Slide 20 of 40Raastech
Machine
A definition that identifies a particular physical piece of hardware
A machine definition is used to associate a computer with the
Managed Servers it hosts
Used by Node Manager in restarting a failed Managed Server
Used by a clustered Managed Server in selecting the best location
for storing replicated session data

Domain
Logically related group of WebLogic Server instances that can be managed from a single set of configuration files
Domain Consists of
Servers
Clusters of servers
Each Domain requires an Administration server
All managed servers in a cluster must be part of same domain
Domain can spread across many machines but the WebLogic version has to be the same

Administration Server
Controls configuration for the domain
Only one Admin server per domain
Admin Server can only control one domain
Hosts the Administration Console
Enables you to start and stop servers from a central location
Enables you to migrate servers and services within the domain
Enables you to deploy applications within the domain
It can be used as a managed server for lower environments

Managed Server Managed Servers host business applications application
components Web services and their associated resources
Each Managed Server can function independent of other
Managed Servers in the domain
Managed servers do not share resources such JDBC JMS
and connection factories
No restrictions on the number of managed servers in a
domain
Can be cloned or added dynamically through the
administration console
Individual Managed Servers are typically added for
capacity and application isolation
Each Managed server stores a local copy of its
configuration

Cluster A cluster is a group of Managed Servers running
simultaneously and working together to provide increased scalability and reliability
Scalability through parallelism
ReliabilityAvailability through replication and redundancy
A Cluster is part of a single domain and each domain can contain multiple clusters
Domain can contain clustered and non-clustered managed servers
A cluster appears as a single instance to most clients
Clusters enable some advanced features such as Whole Server Migration Service Migration and clustered JMS destinations

Load Balancing in a Cluster
For JSPs and Servlets load balancing is external
Web server proxy plug-in (round robin)
HTTP Proxy servlet (ie using WLS as a load balancer)
3rd party hw or sw load balancer (F5 Big IP LTM or Cisco CSM)
EJBs and RMI Objects load balancing is done at connection
Objects are cluster-aware
Load balancing algorithm is stored in the clustered objectrsquos stub
Objects are available on all cluster members remote objects connectuse according the LB algorithm in the stub
Load balancing algorithms Round robin weighted random server affinity
copy Raastech Inc 2015 | All rights reserved Slide 17 of 40Raastech
Failover in a Cluster
Servlets and JSPs
HTTP session state is replicated to a secondary server in the cluster
or to a database
EJBs and RMI Objects
Replicas available throughout the cluster
Exceptions caught and retried on another instance
For Stateful Session Beans state is replicated on a secondary server
copy Raastech Inc 2015 | All rights reserved Slide 18 of 40Raastech
Communication in a Cluster
Peer to Peer using Sockets - used for
Accessing non-clustered objects deployed to another clustered server instance on a different machine
Replicating HTTP session states and stateful session EJB states between a primary and secondary server instance
Accessing clustered objects that reside on a remote server instance
Peer to Peer using Unicast or Multicast - used for
Cluster-wide JNDI updates

Node Manager
Process running on a physical server that enables you to start stop suspend and restart WebLogicServer instances remotely
Runs on each physical server that hosts WebLogicServer instances
Not associated with a domain Can start any server instance that resides on the same physical server
Node Manager is Optional but required to startstop servers using the Administration Console
Required for Whole Server Migration and for some configurations of Automatic Service Migration

Machine
A definition that identifies a particular physical piece of hardware
A machine definition is used to associate a computer with the
Managed Servers it hosts
Used by Node Manager in restarting a failed Managed Server
Used by a clustered Managed Server in selecting the best location
for storing replicated session data

Load Balancing in a Cluster
For JSPs and Servlets load balancing is external
Web server proxy plug-in (round robin)
HTTP Proxy servlet (ie using WLS as a load balancer)
3rd party hw or sw load balancer (F5 Big IP LTM or Cisco CSM)
EJBs and RMI Objects load balancing is done at connection
Objects are cluster-aware
Load balancing algorithm is stored in the clustered objectrsquos stub
Objects are available on all cluster members remote objects connectuse according the LB algorithm in the stub
Load balancing algorithms Round robin weighted random server affinity
copy Raastech Inc 2015 | All rights reserved Slide 17 of 40Raastech
Failover in a Cluster
Servlets and JSPs
HTTP session state is replicated to a secondary server in the cluster
or to a database
EJBs and RMI Objects
Replicas available throughout the cluster
Exceptions caught and retried on another instance
For Stateful Session Beans state is replicated on a secondary server
copy Raastech Inc 2015 | All rights reserved Slide 18 of 40Raastech
Communication in a Cluster
Peer to Peer using Sockets - used for
Accessing non-clustered objects deployed to another clustered server instance on a different machine
Replicating HTTP session states and stateful session EJB states between a primary and secondary server instance
Accessing clustered objects that reside on a remote server instance
Peer to Peer using Unicast or Multicast - used for
Cluster-wide JNDI updates
