Welcome to the Oracle RAC SIG. Our purpose is to advance RAC awareness and adoption while enhancing the experience of current RAC users by providing a forum for technical interchange.
Oracle Real Application Clusters (RAC) provides a highly available, scalable and manageable solution by sharing complete access to a single database among nodes in a cluster. This shared access removes any single point of failure from the database solution. Even during a system fault in one of the nodes, data can continue to be accessed from any of the remaining nodes. Committed work on the failed node is recovered automatically without administrator intervention and without data loss. RAC is an Oracle Corporation exclusive technology that enables building large systems from commodity components and is the foundation for Enterprise GRID computing.

| 09-DEC-10 | Exploting Oracle Tools and Utilities for Monitoring and Testing Oracle RAC Presented by Murali Vallath https://conference.oracle.com/imtapp/app/cmn_jm_hub.uix?mID=142477844%26mConfKey=74063
Oracle has provided several tools and utilities to monitor and test a RAC implementation. Tools such as ORION help benchmark performance of the storage component, the HBA and controllers to help decide between iSCSI and SAN storage. While iSCSI used TCP for data transport SAN used FC for data transport. What is better, how do you find out? Tools such as OSWATCHER, RACDDT, LTOM, OEM will help collect OS performance statistics while performance testing your application in a RAC environment. This presentation will look under the hood at these tools and utilities and help understand its functions, its usage and the kind of information it provides. |
