15 Configuring High Availability for Oracle WebCenter Components
For more information on WebCenter, see the installation guide for the WebCenter product you are working with. For WebCenter Portal, you can also refer toUnderstanding the WebCenter Portal Enterprise Deployment Topology in Oracle Fusion Middleware Enterprise Deployment Guide for Oracle WebCenter Portal.
- About Extending WebCenter Content: Inbound Refinery Components
WebCenter Content: Inbound Refinery components don't use WebLogic Server clustering for scale up and failover. You can deploy and configure multiple, independent Inbound Refinery Managed Servers for WebCenter Content to use. - About WebCenter Content Scaleup and Ports
When you scale up WebCenter Content, the scaled-up server uses a port which is different from the port that you configured in the Configuration Wizard. - About Creating WebCenter Portal Components on Multiple Nodes
In a WebCenter Portal high availability setup, you might see a delay of data appearing on the second node due to a 10-minute default refresh interval. For example, you may see this if you are trying to access a new Portal component that you just created on Node 2 if the Node 1 is processing the request. - About Creating a WebCenter Capture Domain with Oracle SOA
If you create a WebCenter Capture domain with an Oracle SOA component, you must select the JRF-MAN-SVR and WSMPM-MAN-SVR server groups. These server groups ensure that the oracle JRF and Oracle Web Services Manager (OWSM) services target the Managed Servers you are creating. - About Scaling Out WebCenter Capture and Configuring OWSM
OWSM uses cross-component wiring to auto-discover the Policy Manager in a domain. When you use the Configuration Wizard to create or update a domain that includes OWSM, Policy Manager URLs publish to the Local Service table. - About WebCenter Sites Component Connections
WebCenter Sites requires an external component that is up and running when trying to establish connections. If an external component isn't up and running or the connection has timed out, WebCenter Sites doesn't reestablish the connection. - About WebCenter Sites and Multicast
WebCenter Sites relies on multicast support to provide inCache replication across nodes in a clustered environment.

About WebCenter Content Scaleup and Ports
When you scale up WebCenter Content, the scaled-up server uses a port which is different from the port that you configured in the Configuration Wizard.
In the WebCenter Content configuration file, you must specify the IntradocServerPort value for each Managed Server instance. The port for each Managed Server instance that resides on the one machine must be unique. For example, if Content_server1 and Content_server2 are on the same machine, the configuration file should look similar to the following:
IntradocServerPort=4444
IntradocServerPort.UCM_serverd1=4444
IntradocServerPort.UCM_serverd2=4445About Creating WebCenter Portal Components on Multiple Nodes

About Scaling Out WebCenter Capture and Configuring OWSM
OWSM uses cross-component wiring to auto-discover the Policy Manager in a domain. When you use the Configuration Wizard to create or update a domain that includes OWSM, Policy Manager URLs publish to the Local Service table.
OWSM Agent is automatically wired to the OWSM Policy Manager using endpoint entries published to the Local Service table. If, however, you change the domain using tools other than the Configuration Wizard (such as WebLogic Administration Console, Fusion Middleware Control, or WLST), any changes to the Policy Manager URL automatically publish to the Local Service table but the OWSM Agent client isn't automatically bound to the new URL. In this case, you must manually bind OWSM Agent to the Policy Manager URL.

About WebCenter Sites Component Connections
WebCenter Sites requires an external component that is up and running when trying to establish connections. If an external component isn't up and running or the connection has timed out, WebCenter Sites doesn't reestablish the connection.
WebCenter Sites verifies that database connections are active and reestablishes connections only when they are active.
About WebCenter Sites and Multicast
WebCenter Sites relies on multicast support to provide inCache replication across nodes in a clustered environment.
For more about the inCache support in WebCenter Sites, see Using the inCache Framework in Oracle Fusion Middleware Administering Oracle WebCenter Sites.
