In this video you will understand how an Oracle RAC cluster recovers from an Instance Crash which is also called Crash Recovery. The video will use the whiteboard to show you what happens when one of the nodes crashes in a Cluster and how the surviving node recovers the failed node related transactions.

https://dbagenesis.com/p/oracle-11gr2-rac-for-beginners A computer cluster consists of a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (i.e. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, and/or different hardware.

Rapid Home Provisioning can extend a cluster to additional nodes, and scale a RAC Database to additional nodes. This demo shows both of those operations. RHP can also remove DB and GI homes to scale a RAC cluster down, but we don't go through those (very similar) steps here. ================================= To improve the video quality, click the gear icon and set the Quality to 1080p/720p HD.

This protects against unplanned server outages because transparent application failover will re-direct to another server, and also aids the RAC goal of scalability, when a new server instance is genned-in to the RAC cluster.

Oracle Database administrators have to cope with numerous challenges when migrating an existing non-cluster environment to a cluster environment. One of the most significant challenges a DBA faces is to migrate/convert an existing single instance to RAC. Oracle provides several easy methods to carry out the procedure, so it is important to know which method best fits your needs and requirements. The core objective of this presentation is to give you an overview about different methods for migrating an existing single instance to RAC, and help you find the most suitable one for your situation. The session will also explain how to perform the migration in order to minimize the downtime and to improve (speed up) the migration duration whilst dealing with VLDB.

In this proposal, I would like to talk about the methods and tools implemented to Migrate from a 5-Node Oracle RAC to PostgreSQL. It was an Oracle RAC with 5 Nodes designed to automatically load balance and scatter the transactions across multiple nodes for a complex business logic. There was a DR(Disaster Recovery Environment) which was a 5 Node RAC again with the ability to take a Read Traffic for ETL and Reporting. There are several built-in features with Enterprise Version of Oracle which are not claimed to be available for PostgreSQL and thus stopping majority of the users to migrate from Oracle RAC to PostgreSQL. I have overcome all such challenges and implemented a Design without using any external tools or Multi-Master solutions in the market. https://www.pgcon.org/2018/

RAC environments are very complex ones and include many different components. One of the goals of RAC database is to balance the load between the different instances and listeners. In this session we will dive into the load balancing mechanism. We will talk about the client configuration, SCAN listeners, services and more, and see some guidelines and best practices to better utilize the balance between the nodes.
