Using a Proxy with BITeamwork and OBIEE
As part of the configuration process of leveraging a Proxy Server or HTTP Server with OBIEE, one configures the context-root paths accessible for routing to the target application server used by Oracle BI. This logic will apply when using a proxy with BITeamwork and OBIEE as the integration of the BITeamwork application is deployed to […]

JDBC Issue weblogic.descriptor.BeanAlreadyExistsException
Although WebLogic Server is robust, it can be a bit klugy when it comes to some refreshing of loading its core objects such as JEE deployments and even JDBC data source. When upgrading, replacing (or removing and recreating) JDBC data sources we’ve found that one may encounter the JDBC Issue weblogic.descriptor.BeanAlreadyExistsException exception message. This message […]

OBIEE:Difference between High Availability and Scale Out
What is the difference between High Availability and Scale out?
Ans:
High Availability :High availability refers to the ability of users to access a system without loss of service. Deploying a high availability system minimizes the time when the system is down, or unavailable and maximizes the time when it is running, or available.
Scalaing: Scaling is the process of increasing or decreasing the capacity of the system by changing the number of processes available to service requests from Oracle Business Intelligence clients. Scaling out a system provides additional capacity, while scaling in a system reduces capacity. Scaling is also a critical part of configuring a deployment for high availability.Scaling the Oracle Business Intelligence environment applies principally to resource-intensive system processes and Java components. When you deploy more processes, Oracle Business Intelligence can handle more requests while staying responsive to requests.Vertical scaling involves adding more Oracle Business Intelligence components to the same computer, to make increased use of the hardware resources on that computer. For example, Oracle Business Intelligence can be vertically scaled by increasing the number of system components servicing requests on a given computer and results in increased use of the hardware resources on a given computer.Horizontal scaling involves adding more computers to the environment. For example, Oracle Business Intelligence is horizontally scaled by distributing the processing of requests across multiple computers.
