What is Oracle SQL?
SQL stands for Structured Query Language—the language developers use to interact with databases to create, read, update, and delete database records and manage other aspects of those databases. ANSI created the standard for SQL. Many database vendors, like Oracle, expand on this standard to create their version of the language. Oracle SQL is compliant with ANSI SQL standards, with features designed specifically for the Oracle database management system. This RDBMS was released as the first commercially available relational database management system in 1977 and holds the top market share worldwide for relational database management systems. Oracle SQL extends the SQL standard with a procedural language PL/SQL and adds the ability to use the Java programming language.
oracle database administration: Oracle Database is an enterprise database that can handle online transaction processing needs, as well as data warehousing and workloads for enterprise resource planning (ERP). Oracle DB was designed to be a flexible way to handle large applications and massive amounts of structured data.
oracle database: Before starting hands-on practices you need to know technical information about RAC. Start with learning the architecture of RAC and then services that run in a RAC environment and so on.
Oracle database administration: We have used Virtualbox to set up our test environment. The first step is creating virtual machine.
oracle database administration: We need an operating system that will run on our virtual machine. I choose Oracle Enterprise Linux as the operating system.
oracle database administration: There are some prerequisites for installing Oracle RAC. For example, we need a tool for disk management. So setting up ASMlib is one of the issues of this lecture.
oracle dba: Arrange the last steps before setting up Oracle RAC. Create directories, change ownerships, and set some features of Linux to off for Oracle RAC.
oracle database: To create the second member of cluster you can create another virtual machine and apply all steps on it or you can just clone the machine you have created.
oracle rac 12c: Because a RAC database is a share everything database, the two servers that we have created should have shared disk space.
oracle rac: Our servers are ready to install the RAC system. We should start by installing grid infrastructure.
oracle database administration: This is the turn of database software installation. There are some differences from a stand-alone database installation but if you installed a stand-alone database before, this step is not difficult for you.
rac: We are finishing the installation part. Create the database that we will use in all exercises and start to administer Oracle RAC Database.
oracle database administration: CRS (Cluster Ready Services) is responsible for managing high availability options in the cluster. And before you start the database in RAC you should start CRS first.
oracle database administration: Now it is time to start the database. We will see what is happening background while the database is starting by tracing the alert file.
oracle rac: Not only you will just stop database and CRS but also you will try many start and stop options for the database.
oracle database: Disabling CRS prevents the automatic startup of Oracle High Availability Services when the server boots. You need to disable CRS while maintaining of database and servers.
oracle database administration: You can define services on your database. So that it will be easy to manage. For example, you can define a pluggable database as service and so that managing the pluggable database is getting easier.
oracle rac 12c: Killing a session is not usual work of administering the database but sometimes it becomes a lifesaver. For example, if a session uses abnormal system resources it should be handled. Also setting parameters to optimal values is decisive for the success of DBA.
Oracle, oracle sql, oracle database administration, oracle dba: RAC One Node provides higher availability by eliminating the database server as a single point of failure. Similar to Oracle RAC, Oracle RAC One Node uses a shared disk system to provide high availability for Oracle Databases. Unlike Oracle RAC, Oracle RAC One Node provides an Oracle Database failover solution for that facilitates the clustered infrastructure.
Oracle, oracle sql, oracle database administration, oracle dba: Workload management enables you to manage workload distributions to provide optimal performance for users and applications.
oracle database administration: Monitoring the performance of the database is the most common job of the database administrator during the day. The success of finding and tuning performance bottlenecks determines how good you are as an admin.
oracle database: Every single system has its own needs. You should determine your company's needs then design the optimal structure, and finally, deploy your plan.
oracle rac: Cloning Oracle RAC is a way to prepare an Oracle home once and deploy it to many hosts. Every DBA does not need this feature but if you will set up more than one RAC system, it will speed you up.
oracle database administration: The subject of Backup&Recovery is a course issue in itself. We will only briefly mention here to see how to backup and recover a RAC database.
oracle database: Backing up the database is the most critical issue of a DBA. You need to plan an appropriate Backup strategy that will provide no data loss if an event that needs to restore and recover operation occurs.
oracle rac 12c: Restore and recover with no data loss is critical for you to not lose your job. You can see here restoring the whole database on a RAC environment.
oracle database administration: Thank to the scalability of Oracle RAC if your servers can't handle the workload of your system, you can add new server or servers by adding node to the database cluster.
oracle rac 12c: You can exclude a node from the database cluster by deleting a node. The workload will be handled by the remaining servers.

Oracle RAC is a unique technology that provides high availability and scalability for all application types. It prevents the server from being a single point of failure. But DBAs also should be aware of the recent development and it’s no secret how technology is advancing at a rapid rate. New tools are released every day, Oracle updates its system, and it’s crucial to stay on top of the latest knowledge. With this course, you will always have a chance to follow the latest trends.

What careers use Oracle SQL?
Having Oracle SQL skills can add value to many careers. The most obvious is being a database administrator in enterprises that use the Oracle database management system. But SQL dialects are pretty similar, and knowledge of Oracle SQL can apply to many types of relational databases and doesn't limit you to Oracle. Database developers also use Oracle SQL all day long to create new databases and table structures. Most applications require a database to function, so software engineers and web developers also use Oracle SQL frequently. Data scientists must access data to create machine learning models and find trends, and a lot of this data will get stored in databases that require a knowledge of SQL to retrieve and transform. Business analysts also use Oracle SQL to generate reports that help businesses get to their next stage.
What skills should I have before learning Oracle SQL?
There are no prerequisites to learning Oracle SQL. Oracle SQL has a simpler syntax than many standard programming languages and reads almost like English. Most people can understand what a SQL query is trying to do before they even know the language. All you need is an interest in the language and a commitment to learning. That said, some things could help with your Oracle SQL education if you are already familiar with them. If you are familiar with Excel spreadsheets and understand how columns and rows work, you can apply that knowledge to Oracle database tables. It also helps to know at least the concepts of how a relational database management system works. Also, if you already know a programming language, that will help learn Oracle's extended features like PL/SQL.
