In a high availability environment such as the one shown in the figure bellow, it is recommended that Oracle ECM products be set up in a clustered deployment, where the clustered instances access an Oracle Real Applications Cluster (Oracle RAC) database content repository and a shared disk is used to store the common configuration.
A hardware load balancer routes requests to multiple Oracle HTTP Server instances which, in turn, route requests to the clustered Oracle ECM servers.
This Post include the following topics:
1. Shared Storage
2. Configuring the Oracle Database
3. Installing and Configuring ECMHOST1
4. Installing and Configuring WEBHOST1
5. Configuring the Load Balancer
6. Installing and Configuring ECMHOST2
7. Installing and Configuring WEBHOST2
The configuration will include Oracle UCM Product.
Now in Steps one by one:
1. Shared Storage:
Cluster members require shared storage to access the same configuration files. This should be set up to be accessible from all nodes in the cluster.
When configuring Oracle UCM clusters, follow these requirements:
For Oracle UCM clusters, all members of the cluster must point to the same configuration directory. This directory must be on a shared disk accessible to all members of the cluster.
----------------------------------------------------------------------------------------
2. Configuring the Oracle Database:
Configure the Oracle RAC database before completing this procedure.
To run RCU and create the Oracle UCM schemas in an Oracle RAC database repository, follow these steps on any available host:
- Issue this command in the command line: RCU_HOME/bin/rcu
- On the Welcome screen, click Next.
