What is Oracle RAC?

Oracle RAC permits multiple computers to run Oracle RDBMS software in a parallel manner while accessing a single database, thus providing clustering. In a non-RAC Oracle database, a single instance accesses a single database.

In today’s business world, with the growing importance of the Internet, more and more applications need to be available online all the time. One obvious example is the online store application. Many companies want to keep their online stores open 24×7 on 365 days so that customers from everywhere, in different time zones, can come at any time to browse products and place orders.

High Availability (HA) may also be critical for non-customer-facing applications. Oracle databases are often key components of a whole storefront ecosystem, so their availability can impact the availability of the entire ecosystem. An Oracle Database should be scalable and flexible enough to easily adapt to business dynamics and able to expand for high workloads and shrink when demand is reduced. Oracle Real Application Clusters (RAC) running on Linux on commodity X86-64 servers is a widely adopted industry-standard solution to achieve high availability and scalability.

Oracle RAC architecture and components:

In order to establish an Oracle RAC infrastructure, you need to install the following two Oracle licensed products:

Oracle Grid Infrastructure: This combines Oracle Cluster ware and Oracle ASM. Oracle Cluster ware clusters multiple interconnected servers (nodes). Oracle ASM provides the volume manager and database file system that is shared by all cluster nodes.

Oracle RAC: This coordinates and synchronizes multiple database instances to access the same set of database files and process transactions on the same database.

The architecture of Oracle RAC and its two major components: Oracle Cluster ware and Oracle RAC Database.

Grid Infrastructure: Oracle Clusterware and ASM Clusterware is a layer of software that is tightly integrated with the OS to provide clustering features to the RAC databases on a set of servers. Before Oracle 9i, Oracle depended on OS vendors or third-party vendors to provide the Clusterware solution. In Oracle 9i, Oracle released its own Clusterware on Linux and Windows, and in Oracle 10g Oracle extended its Clusterware to other OS. Oracle Clusterware was significantly enhanced in 11g. In 11gR2, Oracle combined Clusterware and Oracle ASM into a single product called Grid Infrastructure. Oracle Clusterware is required software to run the Oracle RAC option, and it must be installed in its own, nonshared Oracle home. Usually, we have a dedicated OS user “grid” to own Grid Infrastructure as well as Oracle ASM instance, which is different from the Oracle RAC database owner “oracle.”

Oracle Clusterware serves as a foundation for Oracle RAC Database. It provides a set of additional processes running on each cluster server (node) that allow the cluster nodes to communicate with each other so that these cluster nodes can work together as if they were one server serving the database users. This infrastructure is necessary to run Oracle RAC.

What are the Hardware Requirements for RAC?

A typical Oracle RAC database requires two or more servers, networking across the servers, and the storage shared by the servers. Although the servers can be SMP Unix servers as well as low-cost commodity x86 servers, it has been an industry trend to move the database server from large SMP Unix machines to low-cost x86-64 servers running on Linux OS, such as Red Hat Enterprise Linux and Oracle Linux.

What are the Benefits of Oracle RAC?

  • High Availability Against Unplanned Downtime
  • High Availability Against Planned Downtime
  • Scalability
  • Reliability
  • Consolidating Database Services
  • Reduce Cost of Ownership
  • Error Detection mechanism that allows Oracle Clusterware to automatically monitors detects and fixes the error if any.

Why Should We Learn Oracle RAC?

As the business grows, transaction volumes can double or triple as compared to what was scoped for the initial capacity. Moreover, for short times, business volumes can be very dynamic; for example, sales volumes for the holiday season can be significantly higher. An Oracle Database should be scalable and flexible enough to easily adapt to business dynamics and able to expand for high workloads and shrink when demand is reduced.

Oracle RAC can satisfy higher availability and Scalability properties which are compulsory for every Organization. So it is better to go with Oracle RAC Online training.

Very nice material and course video available for your reference anytime. I repeatedly watched videos to learn required knowledge. Anyone would definitely miss out the physical presence inside the class while attending the course . I had lot of disturbance at home while class was going on and it didn't give me any seriousness about subject as I didn't see anyone looking at me if I am listening! This factor, someone is looking at me would definitely make me concentrate subject. Also 4 (four) hours of coaching online and very less interaction with people around makes very less impressive learning

My learning with KITS Online Trainings was Golden Gate and SAP Basis training and exam preparation It’s been a worthwhile learning experience - the course was easier to understand than and helped memory retention. Also the online support team were so kind and helpful-when i ran out of time and my exam was a month away they extended my access for extra 30 days. Success all the way
