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!)

01 Overview of table Partition in oracle
 
07:26
Partitioning enhances the performance, manageability, and availability of a wide variety of applications and helps reduce the total cost of ownership for storing large amounts of data. Partitioning allows tables, indexes, and index-organized tables to be subdivided into smaller pieces, enabling these database objects to be managed and accessed at a finer level of granularity. Oracle provides a rich variety of partitioning strategies and extensions to address every business requirement. Moreover, since it is entirely transparent, partitioning can be applied to almost any application without the need for potentially expensive and time consuming application changes. Partitioning allows a table, index, or index-organized table to be subdivided into smaller pieces, where each piece of such a database object is called a partition. Each partition has its own name, and may optionally have its own storage characteristics. From the perspective of a database administrator, a partitioned object has multiple pieces that can be managed either collectively or individually. This gives the administrator considerable flexibility in managing partitioned objects. However, from the perspective of the application, a partitioned table is identical to a non-partitioned table; no modifications are necessary when accessing a partitioned table using SQL queries and DML statements. Partitioning Key ======================== Each row in a partitioned table is unambiguously assigned to a single partition. The partitioning key is comprised of one or more columns that determine the partition where each row will be stored. Oracle automatically directs insert, update, and delete operations to the appropriate partition through the use of the partitioning key. When to Partition a Table ========================== Here are some suggestions for when to partition a table: Tables greater than 2 GB should always be considered as candidates for partitioning. Tables containing historical data, in which new data is added into the newest partition. A typical example is a historical table where only the current month's data is updatable and the other 11 months are read only. When the contents of a table need to be distributed across different types of storage devices. When to Partition an Index ============================= Here are some suggestions for when to consider partitioning an index: Avoid rebuilding the entire index when data is removed. Perform maintenance on parts of the data without invalidating the entire index. Reduce the impact of index skew caused by an index on a column with a monotonically increasing value. Partitioned Index-Organized Tables =================================== Partitioned index-organized tables are very useful for providing improved performance, manageability, and availability for index-organized tables. For partitioning an index-organized table: ============================================ Partition columns must be a subset of the primary key columns Secondary indexes can be partitioned (both locally and globally) OVERFLOW data segments are always equi-partitioned with the table partitions See Also: Oracle Database Concepts for more information about index-organized tables System Partitioning System partitioning enables application-controlled partitioning without having the database controlling the data placement. The database simply provides the ability to break down a table into partitions without knowing what the individual partitions are going to be used for. All aspects of partitioning have to be controlled by the application. For example, an insertion into a system partitioned table without the explicit specification of a partition will fail. System partitioning provides the well-known benefits of partitioning (scalability, availability, and manageability), but the partitioning and actual data placement are controlled by the application. See Also: Oracle Database Data Cartridge Developer's Guide for more information about system partitioning Partitioning for Information Lifecycle Management Information Lifecycle Management (ILM) is concerned with managing data during its lifetime. Partitioning plays a key role in ILM because it enables groups of data (that is, partitions) to be distributed across different types of storage devices and managed individually.

Hello friends in this video i'm going to demonstrate you how to add virtual column in ORACLE 11g step by step. Oracle 11g supports virtual columns which are derived from the other columns in the table. You can use the virtual columns in your queries, you can index them, you can collect the statistics, etc. There are few restrictions on the virtual columns. You cannot write/insert the data into virtual columns. There is no support for index_organized, external, object, cluster, temporary tables.

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!)

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.

Oracle 12c Database New Features - Pluggable Database - Video 1
 
17:25
Oracle 12c Database New Features - Pluggable Database - Video 1 1. Pluggable Database * Oracle 12c introduces a new feature called 'Pluggable Database'. Here Oracle Metadata and user data are totally separated into two sections. One is Container DB (or CDB) which will hold Oracle Metadata. The other is Pluggable DB (or PDB) which will hold user data. How does a Pluggable Database work? In the regular database, Oracle's metadata and user's application data are integrated. For beginners, Oracle Metadata is the data that is present when you install a new Oracle Database (without any sample schemas). Even though it can be called as an empty database, it still has data provided by Oracle. This data is needed by the database to function. For example, the objects owned by SYS, SYSTEM are mostly metadata. Then user data is entered into that database. They will go under multiple user schemas. Now the database is being used by the users. Now a situation arises so that we need to create another database on the same server. Why? Let us say that you need to provide data to two clients. And you don't want one client to other's data. And your data is contained in an extensive set of application schemas. In this case, making a copy of those applications schemas into a different set of names and making them reside in the same database is very difficult. So, you provide two separate databases. This also ensures that there is no security violation. So, we install another new database, which comes with Oracle Metadata. Then we load the user data. In this method, which is currently being used (Year 2013), there will be a need for more memory for both the database instances. There will be two SGAs, two sets of smon, pmon and other background processes running. Then if we need to copy one database to another, we need to rely on extensive procedures which includes exporting the data from the source database first, then removing the data at the target and then finally loading the data in there. After that, we need to take care of the user security and object privileges etc. So, if you want to provide data for multiple tenants, that is multiple clients, then with the current set of features (till Oracle 11g), we have to create multiple databases. That is, one database for one client. In otherwords, there is no multi-tenancy. Multi-Tenancy is becoming an important requirement in cloud infrastructure, these days. You would like to have the ability of providing data to multiple clients from the same database system with full confidence in security. This can be achieved in Pluggable Database. In a Pluggable Database, Oracle basically separates its metadata entirely from the user data. Metadata is stored in a section called Container DB. Then the user data are stored in Pluggable DBs. It also stores user metadata in the Pluggable DB. By the way, what is user metadata? For example, earlier, the list of user accounts that exist in a database is tightly inegrated with Oracle Metadata. Now, with the separation of Container DB and Pluggable DB, the user accounts must exist in the Pluggable DB. So, the Pluggable DB not only contains user data, but also some user metadata. So, what are the benefits? * Multi-Tenancy - We can bring in two Pluggable DBs under one Container DB. Both will be totally segregated, but yet controlled by one instance. This is an important feature for SaaS (Software as a Service) platforms, Cloud, On-Demand and Vendor Managed Application solutions. * Easy cloning/copying. Now the cloning and copying the databases across servers would be much easier. Just clone a Pluggable DB and plug-it-in in a different server. * Very easy upgrades and patching.
