04 How to configure Hash partition in Oracle
Hash partitioning Use hash partitioning if your data does not easily lend itself to range partitioning, but you would like to partition for performance and manageability reasons. Hash partitioning provides a method of evenly distributing data across a specified number of partitions. Rows are mapped into partitions based on a hash value of the partitioning key The following example shows how to create a hash partition table. The following example creates a hash-partitioned table. The partitioning column is partno, four partitions are created and assigned system generated names, and they are placed in four named tablespaces (tab1,tab2, ...). CREATE TABLE products (partno NUMBER, description VARCHAR2 (60)) PARTITION BY HASH (partno) PARTITIONS 4 STORE IN (tab1, tab2, tab3, tab4);

How to Code Oracle Analytic Functions
Many more free Oracle Database and SQL tutorials at http://skillbuilders.com/free-oracle-tutorials. SQL is a language that allows you to perform queries to answer a wide range of questions about your data. While standard SQL is quite powerful, there are many questions that it cannot answer at all or that it can only answer with complex and inefficient SQL workarounds. Questions about running totals, percent of total, and ranking within a group fall into this area. Also, more complex issues such as Top-N within a group and aggregates over a range also fall in this arena. These questions can be easily answered via a new class of SQL statements called Analytic Functions. This presentation will show you how to use Oracle's Analytic Function extensions to SQL to answer these questions simply and efficiently.

Part 5: Partition creation, ASM RPM installation & ASM DISK creation & grid software Installation
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).

SQL Tutorial - Window Functions - Lag and Lead
Another video brought to you by BeardedDev, bringing you tutorials on Business Intelligence, SQL Programming and Data Analysis. In this video I talk about using Lag and Lead in Windows Functions. This video covers the requirements to pass the exam: If you would like to follow along with the tutorial please run the SQL below: IF OBJECT_ID(N'dbo.Sales', N'U') IS NOT NULL DROP TABLE dbo.Sales; GO CREATE TABLE dbo.Sales ( Sales_Id INT NOT NULL IDENTITY(1, 1) CONSTRAINT PK_Sales_Sales_Id PRIMARY KEY , Sales_Customer_Id INT NOT NULL , Sales_Date DATETIME2 NOT NULL , Sales_Amount DECIMAL (16, 2) NOT NULL ) INSERT INTO dbo.Sales (Sales_Customer_Id, Sales_Date, Sales_Amount) VALUES (1, '20180102', 54.99) , (1, '20180103', 72.99) , (1, '20180104', 34.99) , (1, '20180115', 29.99) , (1, '20180121', 67.00) Lag and Lead are useful for performing trend analysis, in the example I show how we can display a customer spending trend. Lag will show the previous value. Lead will show the next value. Lag and Lead accept multiple parameters as demonstrated in the video: LAG([Column], [Offset], [Value if NULL]) The example of LAG and LEAD in the video can be shown by executing the below SQL query: SELECT Sales_Customer_Id , Sales_Date , LAG(Sales_Amount, 2, 0) OVER(PARTITION BY Sales_Customer_Id ORDER BY Sales_Date) AS PrevValue , Sales_Amount , LEAD(Sales_Amount, 2, 0) OVER(PARTITION BY Sales_Customer_Id ORDER BY Sales_Date) AS NextValue FROM dbo.Sales Please feel free to post comments.

Using Oracle to read data from SQL Server
Hi everyone, Andy from Easysoft Limited here, what I want to show you today is how to get data from SQL Server into Oracle. Now for this we will be accessing SQL Server 2014 from Oracle 12 and getting data across. This could be quite easily be any SQL Server version from 2008 and any Oracle version from 11.2, the configuration and process is the same. We can obviously get access to data on SQL Server prior to 2008 and Oracle prior to version 11.2 but it will need a different configuration to what I am going to show you today The plan is also to add more data to the SQL Server table and show this new data back in Oracle. To start off you'll need access to ensure that you have access to your SQL Server and Oracle databases. You'll also need the Easysoft SQL Server ODBC Driver available from www.easysoft.com; just download it, install it and request the free 14 day trial licence. Before we start we need to make some changes to the standard Easysoft config files. cat /etc/odbc.ini Here I have changed Mars Connection to Yes. It must be set to "Yes" if you are connecting to SQL Server 2005 or newer. Easysoft supports all SQL data types from the version of SQL Server from version 7. Oracle supports data types that are common to most ODBC Drivers, but not some of the SQL Server ones. If you intend to access VARCHAR(MAX) for example, then there are some additional settings that need to be set up. Now as I would like to show you VARCHAR(MAX) data moving from SQL Server to Oracle, I have made the relevant change. As you can see, VarMaxAsLong says "Yes" We now need to create a link from Oracles Database Gateway (DG4ODBC) to the ODBC datasource that we already have, this is done in an init(sid) oracle file; let's have a look at our file. cat $ORACLE_HOME/hs/admin/initsqlsrv.ora Please note that HS_NLS_NCHAR must be set to UCS2 Oracle assume that most database vendors use UTF-8 for wide characters, however Easysoft, like almost all ODBC Driver vendors (including Oracles own ODBC Driver) uses UCS2 for wide characters. So that's the link between DG4ODBC and the datasource setup correctly. Next we need to set up the Listener entry The Oracle Listener waits for incoming requests from the Oracle database. For the Oracle Listener to listen for requests, information about DG4ODBC must be added to the Oracle Listener configuration file, listener.ora cat $ORACLE_HOME/network/admin/listener.ora The PROGRAM=dg4odbc tells the Listener that we are wanting to use the Oracle database gateway to communicate with ODBC. The ENVS=LD_LIBRARY_PATH tells Oracle what library to load Now that's all set up and OK we need to tell Oracle which server to attach the listener entry to. This is done in tnsnames.ora, and he is the file that we ensured was set up earlier. cat $ORACLE_HOME/network/admin/tnsnames.ora The Oracle Listener now needs to be restarted. lsnrctl stop lsnrctl start OK, that's now started the Listener up again. So we have ensured that all the configuration files are set up correctly. The Listener and tnsnames.ora both set up OK. The final step is to create a link from the Oracle database to the "tnsnames.ora" entry. CREATE PUBLIC DATABASE LINK ODBC CONNECT TO "test" IDENTIFIED BY "test" USING 'sqlsrv_ptr'; Right, that's all done. Let's access the data in SQL Server now. select * from [email protected]; Where 'demo' is the name of the SQL Server table and 'odbc' is the public database link name. OK, there we have the data. So to recap, I'm in Oracle and we have managed to read the data from SQL Server. Let's just add an additional row in that SQL Server table and retrieve the new data in Oracle. quit; /usr/local/easysoft/unixODBC/bin/isql.sh -v sqlsrv insert into demo values (2,'Easysoft') select * from demo select * from [email protected]; And there is the new data. Easysoft Limited can help you with your data access ... for our full range of ODBC and JDBC Drivers, Bridges and Gateways visit easysoft.com Be sure to let us know if you have any comments or questions. Until next time, thanks again and we'll see you again soon.

Vertical - Partition in SQL Server - Part 2
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Vertical partitioning divides a table into multiple tables that contain fewer columns. The two types of vertical partitioning are normalization and row splitting a) NORMALIZATION is the standard database process of removing redundant columns from a table and putting them in secondary tables that are linked to the primary table by primary key and foreign key relationships. b) ROW SPLITTING divides the original table vertically into tables with fewer columns. Each logical row in a split table matches the same logical row in the other tables as identified by a UNIQUE KEY column that is identical in all of the partitioned tables.

Following environment was used to test this setup on VMWare. Operating System : OEL 5.3 (32 bit) Oracle Version : Grid Infrastructure Version : The approach would remain same for different 11.2 patchset on Linux platform. We will NOT be covering installation of VMWare, guest OS and VMWare tools in this article. You can find lot of articles helping you to do this. So lets start with list of tasks that needs to be done to accomplish our goal.

How to Move a Datafile in Oracle Database - Part 1
Dozens of free Oracle tutorials at http://skillbuilders.com/free-oracle-tutorials. See Part 2 (the demonstration) of this tutorial at http://skillbuilders.com/How-to-Move-Datafiles-Oracle-12c. How do you move a datafile in an Oracle Database? Well, it just got a lot easier in 12c! Watch this free video tutorial - OCM John Watson of SkillBuilders will demonstrate both techniques, 11g and 12c. There are many reasons to move a datafile in an Oracle database. Here are just a few: Renaming datafiles to a standard Moving from one file system to another Converting from file system storage to ASM Changing from SAN to NFS storage In 11g, we need to take the tablespace offline, meaning downtime. Argh! In 12c, all that is required is ALTER DATABASE MOVE DATAFILE; this is an online operation with zero downtime. Even "critical" files such as the files associated with the SYSTEM tablespace can be moved online. Consider the ease of migrating to ASM this provides! This also functions in an Active Data Guard standby environment. And, there are syntax options that allow you to keep or delete the original file. Very cool stuff.

SQL: LEAD Function
In this tutorial, you'll learn how to make use of lead function in oracle sql PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Over clause in SQL Server
over partition by in sql server 2008 sql server over clause partition partition by clause in sql server 2008 over partition by clause in sql In this video we will discuss the power and use of Over clause in SQL Server. The OVER clause combined with PARTITION BY is used to break up data into partitions. Syntax : function (...) OVER (PARTITION BY col1, Col2, ...) The specified function operates for each partition. For example : COUNT(Gender) OVER (PARTITION BY Gender) will partition the data by GENDER i.e there will 2 partitions (Male and Female) and then the COUNT() function is applied over each partition. Any of the following functions can be used. Please note this is not the complete list. COUNT(), AVG(), SUM(), MIN(), MAX(), ROW_NUMBER(), RANK(), DENSE_RANK() etc. Example : SQl Script to create Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10), Salary int ) Go Insert Into Employees Values (1, 'Mark', 'Male', 5000) Insert Into Employees Values (2, 'John', 'Male', 4500) Insert Into Employees Values (3, 'Pam', 'Female', 5500) Insert Into Employees Values (4, 'Sara', 'Female', 4000) Insert Into Employees Values (5, 'Todd', 'Male', 3500) Insert Into Employees Values (6, 'Mary', 'Female', 5000) Insert Into Employees Values (7, 'Ben', 'Male', 6500) Insert Into Employees Values (8, 'Jodi', 'Female', 7000) Insert Into Employees Values (9, 'Tom', 'Male', 5500) Insert Into Employees Values (10, 'Ron', 'Male', 5000) Go Write a query to retrieve total count of employees by Gender. Also in the result we want Average, Minimum and Maximum salary by Gender. This can be very easily achieved using a simple GROUP BY query as show below. SELECT Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender What if we want non-aggregated values (like employee Name and Salary) in result set along with aggregated values You cannot include non-aggregated columns in the GROUP BY query. SELECT Name, Salary, Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender The above query will result in the following error : Column 'Employees.Name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause One way to achieve this is by including the aggregations in a subquery and then JOINING it with the main query as shown in the example below. Look at the amount of T-SQL code we have to write. SELECT Name, Salary, Employees.Gender, Genders.GenderTotals, Genders.AvgSal, Genders.MinSal, Genders.MaxSal FROM Employees INNER JOIN (SELECT Gender, COUNT(*) AS GenderTotals, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender) AS Genders ON Genders.Gender = Employees.Gender Better way of doing this is by using the OVER clause combined with PARTITION BY SELECT Name, Salary, Gender, COUNT(Gender) OVER(PARTITION BY Gender) AS GenderTotals, AVG(Salary) OVER(PARTITION BY Gender) AS AvgSal, MIN(Salary) OVER(PARTITION BY Gender) AS MinSal, MAX(Salary) OVER(PARTITION BY Gender) AS MaxSal FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server_29.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

How to Dual Boot Windows 8 and CentOS 7
I haven't made a video in a while. Here's how to dual boot Windows 8 and CentOS 7. CentOS: https://www.centos.org/download/ Download CentOS-7.0-livecd.iso from: https://www.centos.org/download/ Universal USB Installer: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/ Use Universal USB Installer to install CentOS 7.0 onto a USB Flash Drive. Right click on This PC and click Manage. Create a partition by shrinking the main drive's volume. Use the partition for a new drive. Restart. Use F12 to go into Boot Options. Select USB Storage Device and proceed. Under manual partitioning, click on the minus to free the partition you just created. Now click on the + and add the following partitions: /home - 9000 MB /swap - 2000 MB / - everything else (For me, 143.6 GB) For each of these partitions, make sure they are of type Standard and have file format: ext4 Now, install CentOS 7, and reboot into CentOS. Once booted, open up a terminal. Type: sudo vim /boot/grub2/grub.cfg OR sudo gedit /boot/grub2/grub.cfg (gedit is more like notepad if you're unfamiliar with vim) Vim is a text editor. You can also use gedit, vim commands: i is to insert text esc is to exit insert mode :q is to quit vim :x is to quit and save vim Add the following to grub.cfg to create a menu entry for Windows 8: menuentry "Windows 8" { set root='(hd0, 2)' chainloader +1 } Click on the drive from the file explorer to find out what sda number the storage of Windows is on. For me, since Windows 8 was on sda3, I knew that the boot drive for Windows was on 2 (the number above). Reboot and you have a Windows 8 entry.
