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.

Oracle Database Quality of Service Management
 
01:01:28
Held on August 28 2018 Click on SHOW MORE for video highlights! In our August session, Mark Scardina welcomed Barry Gleeson who was responsible for architecting the Oracle Database Quality of Service Management feature that provides operational runtime autonomous performance management of Oracle RAC databases. Questions ranged across the full gambit of design, functionality and best practices. 01:55 - What is Oracle’s goal in developing QoS Management? 03:02 - What collection of servers and databases does a QoS Management instance manage? 04:10 - How does QoS Management define and measure Response Times? 05:40 - What types of actions does QoSM recommend to help maintain Response Time Objectives when there is a load surge? 10:17 - What actions will QoSM recommend when load is so large that all Response Time Objectives cannot be met at the same time? 12:10 - What does QoSM do when a Response Time problem is detected, but none of the available Actions helps or is appropriate? 15:20 - Since you can rank workloads how can I manage them when their rankings change – ex: weekdays and weekends? 18:32 - Can these policies be switched on a schedule automatically? 19:15 - What type of user interfaces does QoS Management support? 21:00 - What QoS Management functionality is in Oracle Enterprise Manager? 23:17 - Is having QoSM managing the DB resources the only benefit of this product? 31:50 - What is the best practice to make use of QoSM modes? 36:22 - Does QoS Management require any specific database deployment? 38:10 - For QoS, we are evaluated SQL that is already running. Is there a way to prevent new SQL from being fired if system is already overloaded? 39:55 - How about using a (custom defined) function to perform consumer group mapping? 42:22 - The problem we are facing is the module/action are dynamic generated. Can we use a custom defined function to generate the list? 44:28 - What if module and action are from URL endpoint? 43:44 - Does QoSM support wildcard matches, more advance mapping like regexp or even from a table that I can provide the list? 46:45 - Which versions of Oracle databases does QoS Management support? 48:15 - Can you also cover new feature QoS (ORM) added in 18c before we end today? 49:50 - How does QoS Management specifically support classifying requests into Performance Classes? 50:15 - What is the overhead of using QoS Management? 52:38 - How do I change service during a session? 54:51 - Does QoS Management negatively affect an application’s availability? 56:00 - What happens should the QoS Management Server fail? 57:18 - Are there any limitations on the types of applications that Oracle QoS Management can measure and monitor? 59:18 - Are there any limitations on the types of workloads that Oracle QoS Management can manage?

R tutorial: connecting to a database
 
03:38
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

SQLAlchemy: Connecting to a database
 
03:10
Learn how to connect to your database: https://www.datacamp.com/courses/introduction-to-relational-databases-in-python In the python world, there are several great tools that we can use when working with databases. One of those is SQLAlchemy that we will be using throughout this course. SQLAlchemy will allow us to generate SQL queries by writing Python code. You should still consider learning how to write queries in SQL as well. SQLAlchemy has two main components. The part we will be focusing on is often referred to as "core" part of SQLAlchemy. It's really focused around the relational model of the database. Additionally, there is the Object Relational Model or ORM part of SQLAlchemy that is really focused around data models and classes that you as a programmer create. There are many different types of databases, and each database type has its own quirks and unique capabilities. You'll commonly find SQLite, PostgreSQL, MySQL, Microsoft SQL Server, and Oracle when working with data. SQLAlchemy provides a way to operate across all of these database types in a consistent manner. To connect to a database, we need a way to talk to it, and an engine provides that common interface. To create an engine, we import the create_engine function from sqlalchemy; we then use the create_engine function and supply it a connection string that provides the details needed to connect to a database. Finally once we have an engine, we are ready to make a connection using the connect method on the engine. It's worth noting that SQLAlchemy won't actually make the connection until we give it some work to execute. So to review, an engine is the common interface to the database, which requires a connection string to provide the details used to find and connect to the database. Before we go any further, let's talk a bit more about connection strings. In their simplest form, they tell us what kind of database we are talking to and how we should access it. In this example, you can see that we are using the sqlite database driver and the database file named census_nyc.sqlite which is in the current directory. Now that we have an engine and a connection, we need to know what tables are in the database. We'll start again by importing the create_engine function and creating an engine to our database. Finally, We can use the table_names method of the engine which returns a list of tables. Once we know what table we want to work on, we need a way to access that table with python. To do that we are going to use a handy process called reflection, which reads the database and builds a Table object that we can use in our code. We already have created our engine, so we begin by importing the MetaData and Table objects needed for reflection. The MetaData object is a catalog that stores database information such as tables so we don't have to keep looking them up. To reflect the table, we initialize a MetaData object. Next, we use the SQLAlchemy Table object and provide the table name we got earlier from the table_names method. We also supply our metadata instance, and then instruct it to autoload the table using the engine. Finally, we can use the function repr to view the details of our table that we stored as census. This allows us to see the names of the columns, such as 'state' and 'sex', along with their types, such as VARCHAR and INTEGER. This process of reflection may seem a bit of an overhead, but it will make understanding your databases and extracting information from them far easier downstream. Now it's your turn to practice writing connection strings, connecting to databases and reflecting tables. Then we'll be back here writing our first SQL queries.
