Oracle and NEC Joint White Paper: WebLogic Server Active GridLink for Oracle RAC Testing Scenarios and Results
By Frances Zhao-Oracle on Aug 09, 2013
Oracle and NEC have been jointly invested on verifying and testing the Active GridLink for RAC solution implemented within Oracle WebLogic Server which gives the rich functionality for Oracle Database Real Application Clusters integration.
The combination of Oracle WebLogic Server Data Source and Connection Pooling solutions and Oracle RAC provides a high-end mission-critical environment offering performance, high scalability and availability features. Load-balancing and Affinity capabilities offersignificant performance improvement for online transaction processing scenarios, as well as improving throughput and total response time. Failover solution gives end-to-end rapid failure detection supporting graceful shutdown for planned and unplanned Oracle RAC node outages.
In this paper, we start with a brief introduction to Oracle RAC and an overview of the Oracle RAC features supported in Oracle WebLogic Server 11g and 12c. We then focus on details of the effort that have been jointly done with Oracle and NEC with all the detailed testing scenarios and testing results, along with the analysis. The background and overview of NEC’s test of Active GridLink for RAC will be covered in details. The technical details about Runtime Connection Load Balancing, Web Session Affinity, Fast Connection Failover, and how to remove and add the additional RAC node with zero-downtime will be discussed with different use cases.
