Oracle RAC Components | Basic cluster components
 
12:51
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.

Cache Fusion is simply fusing or adding of cache memory so that the availability of the data will be increased and time to fetch a particular block will be decreased because the cache is shared from one instance to the other.

How Oracle RAC Cache Fusion Works Part 1 of 6
 
06:02
Learn the mysteries of how Oracle RAC Cache Fusion works. In this lesson you will see the tutorial agenda plus a brief history of Oracle clustering (parallel server) and the problems associated with disk pinging. Cache Fusion is the secret to making Oracle Real Application Clusters (clustering) a scalable database platform. You will learn how cache fusion works, the differences between global cache current and consistent read transfers, the differences between two-way and three-way transfers and the associated wait events. Oracle Ace and author Brian Peasland provides a demonstration of global cache transfers in action by utilizing Oracle Trace. Prerequisites: Knowledge of Oracle Architecture including the concept of an Oracle instance, the buffer cache, how data is moved into the buffer cache and an understanding of wait events. Brian is a certified Oracle ACE who has been in the IT field for over 25 years and has worked as a computer operator, operations analyst, systems administrator, application developer and for more than half of his career as a database administrator. He holds a B.S. in Computer Science and a M.S. in Computer Science, specializing in database systems. Brian has been a member of SearchOracle.com’s Ask The Experts since 2001 and now contributes articles to the site. He regularly contributes to the My Oracle Support and Oracle Technet communities. He can be followed on Twitter on @BPeaslandDBA and maintains a blog at http://www.peasland.net. Brian is the author of “Oracle RAC Performance Tuning” on Rampant TechPress.

How does an Oracle database start? - Database Tutorial 38
 
12:39
Video 38 How does an Oracle database start? - Database Tutorial 38 How does an Oracle database start? - Database Tutorial 38 The startup of sequence of an Oracle Database. 1) Startup process looks for a parameter file in the default location. 2) If a parameter file is found, it then parses it and gets the information about the control files. 3) With that information, it reads the control files. 4) Upto this point, we can say that the Oracle Instance has been started in nomount mode. 5) The same can be achieved by issuing the following command in sqlplus. a) startup nomount; 6) Then, from the control files, the Instance gets to know about the details of the database and its related files. 7) It then 'mounts' the database. 8) At this point, the database has been started. But it can be only accessed by the DBAs. 9) This is called 'mount' mode. 10) The same can be achieved by issuing the following command in sqlplus. a) startup mount; 11) Then, once the database has mounted, it gets opened for other users. 12) This is called 'OPEN' mode. 13) This is the final mode of a startup process after which the database is available for use. 14) The same can be achieved by issuing the following command in sqlplus. a) startup 15) That concludes the startup.

Extended distance Oracle RAC: zero downtime, high speed, commodity hardware only
 
51:11
Oracle Real Application Clusters (Oracle RAC) offer unique capabilities for high-availability and local disaster recovery of mission-critical databases. Zero downtime can be achieved in cases of localized disasters by using two or three sites located up to 100km apart. Unlike replication techniques, in extended distance clusters the data is mirrored synchronously across the sites. At any given time all locations have exact full copy of the data. In this webinar you will learn how to build high-speed extended distance Oracle RAC clusters using commodity servers, commodity NVMe SSDs, and FlashGrid software.

Introduction to Oracle Listener

https://dbagenesis.com/p/oracle-11g-advanced-dba DBA Genesis provides all you need to build and manage effective Oracle technology learning. We designed DBA Genesis as a simple to use yet powerful online Oracle learning system for students. Each of our courses is taught by an expert instructor, and every course is available on demand. A listener is a separate process than your database processes which runs on the database server to accept incoming connections. Any client connection first lands on to database listener and then its handed over to the PMON process. All the databases running on a server must have their services registered with the listener or else listener will not be able to accept the incoming connections.
