Read the Blog: https://www.calebcurry.com/blogs/database-clustering/intro-to-database-clustering Get ClusterControl: http://bit.ly/ClusterControl In this video we are going to be discussing database clustering and how to manage database clusters with ClusterControl. Database clustering is when you have multiple computers working together that are all used to store your data. There are four primary reasons you should consider clustering. Data redundancy, Load balancing (scalability) High availability. Monitoring and Automation That is an intro to a few of the reasons having a cluster is a good idea. Obviously, not everyone needs a cluster. A cluster can be overkill. But the best way to know is to learn more about them, so I’ll see you in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

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.

Database Clustering Tutorial 2 - Terminology
 
08:06
Read the Blog: https://www.calebcurry.com/blogs/database-clustering/database-clustering-terminology Get ClusterControl: http://bit.ly/ClusterControl The next thing I wanted to discuss was some terminology. When I started studying clustering I was totally confused and lost. Thankfully, some of the people at SeveralNines, who made the ClusterControl software, saved the day. But even with that help, I had to do some real digging to truly understand some terminology. The terminology we are going to discuss in this video is: Cluster Nodes (Master and Slave) Topologies (Master-master and Master-slave) So once we install a database instance on a machine, we have a node. We do this with multiple computers and connect them. Then we cluster. This cluster is either going to be a master-master cluster, or a master-slave cluster. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Database Design 39 - Indexes (Clustered, Nonclustered, Composite Index)
 
13:28
This video covers the basics of indexes. Indexing is an extremely important step of database design. Without Indexes database queries can take a substantial amount of time and hog system resources. The main two classifications of indexes are clustered and non-clustered indexes. Clustered indexes are usually the primary key and determine how the data is actually stored in the table. These are the fastest and most effective. Non-clustered indexes sort a reference to data that is still fast but doesn't actually determine how the data is structured. The best tip I can give you is to use indexes but don't over use them. Having loads of indexes on columns that are barely ever in a where clause or join can bog down the database. This is because every time the table is updated the index must also be updated! When a database looks through a table for certain where conditions on a column that does not have an index, it does an entire table scan. This is not a good practice for large databases (or even small databases but not as bad). With an index the database will do an index seek and quickly find the data you are looking for. Composite indexes consist of two or more columns within one index. Use these when you plan on using the two columns together for a database query WHERE clause.

Well, unfortunately, it’s not the easiest process in the world. The good part, though, is that it is quite the learning experience, and it’s not really hard, it just takes some time. One of the reasons it can take so much time is because not everyone has a bunch of database servers laying around to setup a cluster. But don’t worry, I’m gonna be teach you everything you need to know to set up a database cluster and start working with your data. I’ll also show you how to do it using virtual machines so you don’t have to set up a bunch of computers. To top it off, I’ll do it completely free of charge.

What is Oracle Real Application Cluster - IT Shorts
 
01:31
What is Oracle Real Application Cluster - IT Shorts You go to a bank. And there is a teller. Actually there is only one teller. What happens? All the people wait in line. The teller acts as an interface between the client and the bank's documentation system. Right? Now imagine, there are two tellers. The queue can move faster. Why? Because two tellers can serve more people than one teller in a given time. However, both the tellers would access the same bank's documentation system. Now, imagine a regular, standalone Oracle database system. One database server, Talking to one storage device where the database is stored. And that server serves the clients. Now, let me add one more database server. And make this server to access the same database stored in that same storage device. Now, two servers can serve those clients more efficiently. If one server goes down, the service is still online. Because the other is still serving. This is called Oracle Real Application Cluster. Oracle Real Application Cluster can address scalability and high-availability requirements of an organization.

Ensuring Your Oracle RAC Databases Meet Your Business Objectives at Runtime
 
45:15
Over a decade ago Oracle Real Application Clusters (RAC) brought the required enterprise level scalability and availability functionality necessary to support Oracle databases in business critical applications. This session will introduce an Oracle RAC database classification framework that supports measuring and monitoring workloads aligned with business applications and their objectives and specified via policies to meet changing business criticality. Learn how to use this framework, enhanced in 12.1.0.2 and included in Oracle QoS Management as part of the Oracle RAC license, to classify your 11.2+ database workloads within or across applications, identify actual production runtime performance capability and bottlenecks, and understand and set realizable performance objectives. Learn how these can then be runtime monitored through an EM Cloud Control dashboard and if violated, alerted via EMCC notifications. This session will also cover, new in 12.1.0.2, database workload rankings that govern database startup order and LMS scheduling and how this can be managed through the same performance policies.

Real Application Clusters Oracle Real Application Clusters (RAC) is a database clustering solution that allows more than one instance to mount and open an Oracle database. RAC can only be used on special clustered systems with shared disk storage and a private network interconnect. A normal Oracle installation consists of a single Oracle instance that accesses a database on the same computer system. In contrast, RAC allows multiple instances on different computer systems (nodes in a cluster) to access the same database files simultaneously. Communication between instances is managed by the Distributed Lock Manager (DLM). To address the possibility of two or more instances attempting to modify the same information simultaneously, Oracle uses up to ten additional background processes, named LCK0 through LCK9, to lock the resources in use by these instances. RAC is available with Oracle Enterprise Edition, and under certain conditions, with Standard Edition as well. These restrictions (for Standard Edition) include: • Must use Oracle Clusterware (no third-party clusterware allowed); • Must use ASM to store database files; and • Can only use a max of 4 CPU sockets in the cluster (either 2 nodes with 2 CPUs each, or 4 nodes with 1 CPU each). • RAC was previously called Oracle Parallel Server (OPS). Oracle re-branded OPS as RAC when they released Oracle 9i. Benefits Running Oracle in RAC mode can benefit you in the following ways: • High availability - If some nodes fail, the remainder of the nodes will still be available for processing requests. Failover support is available from Oracle 8 with Oracle's Transparent Application Failover (TAF) technology and from Oracle 10g, server side load balancing. • Speedup (increased transaction response time) - RAC normally adds some overhead. However, for some DSS applications one can achieve increased performance by running operations in parallel (mainly for DSS applications). • Scale-up (increased transaction volume) - RAC can be used to provide increased application scalability (mainly used for OLTP applications).

This video demonstrates the essence of database clustering which is one of the solutions in order to achieve a high data availability in a data center using Open Source technologies. It is implemented through MySQL NDB Cluster in a virtual environment. The virtual machines are powered by Ubuntu Linux 16.04. The step-by-step instructions in setting up such high data availability solution can be browsed or downloaded from this link: https://www.oercommons.org/authoring/25110-distributed-database-systems-through-database-clus
