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!

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.

Non-Container Name =NCDB convert to PDB-NCDB Container DB Name=CDB =========================== Steps for Conversion. Step 1. Cleanly Shutdown the Non-CDB Database Instance. ==- set environment to NCDB ==- sqlplus / as sysdba ==- Shutdown immediate Step 2. Once You Have Cleanly Shutdown the Database, Start Up the database in Mount Exclusive Mode and Open the Database in Read-Only Mode. ==- set environment to NCDB ==- sqlplus / as sysdba ==- startup mount exclusive ==- alter database open read only; Step 3. Generate a Pluggable Database Manifest File from the Non-Container Database. ==- set environment to NCDB ==- sqlplus / as sysdba ==- exec dbms_pdb.describe (pdb_descr_file=-'E:\app\oracle\manifest\NCDB_manifest_file.xml'); Step 4. Shutdown the NON-CDB file Once Step 3 Completes Successfully. ==- Set environment to NCDB ==- sqlplus / as sysdba ==- shutdown immediate Step 5. Start the CDB (CDB) if it’s Not Already Up and Check the Compatibility with CDB. ==- set environment to CDB ==- sqlplus / as sysdba ==- startup (If not up) ==- Run below at SQL prompt. SET SERVEROUTPUT ON; DECLARE Compatible CONSTANT VARCHAR2(3) :=CASE DBMS_PDB.CHECK_PLUG_COMPATIBILITY (pdb_descr_file =- 'E:\app\oracle\manifest\NCDB_manifest_file.xml') WHEN TRUE THEN 'YES' ELSE 'NO' END; BEGIN DBMS_OUTPUT.PUT_LINE(compatible); END; / Step 6. Once it Completes Successfully, Query PDB_PLUG_IN_VIOLATIONS View from CDB Database for Any Errors. ==- set environment to CDB ==- sqlplus / as sysdba ==- select name, cause, type, message, status from PDB_PLUG_IN_VIOLATIONS where name='NCDB'; Note: "There should be no violations reported. If there are any, you need to fix it before proceeding". Step 7. Connect to the CDB Where Database has to be Plugged in Using the Noncdb Manifest File and Plug the PDDB12C Database. ==- set environment to CDB ==- sqlplus / as sysdba ==- CREATE PLUGGABLE DATABASE NCDB USING 'E:\app\oracle\manifest\NCDB_manifest_file.xml' COPY FILE_NAME_CONVERT = ('E:\APP\ORACLE\ORADATA\NCDB\', 'E:\app\oracle\oradata\CDB1\'); Note: "Below options are supported and you can chose one based on the env" 1) COPY: The datafiles of noncdb remains intact and it is copied to create PDBs at new locations and keep original datafiles intact at the original location. (This would mean that a noncdb database would still be operational after the creation of a PDB). 2) MOVE: The datafiles of noncdb are moved to a new location to create a PDB. In this case, noncdb database would not be available after a PDB is created. NOCOPY: The datafiles of noncdb are used to create a PDB2 and it uses same existing location. In this case, a noncdb database would not be available after a PDB is created. You can use FILE_NAME_CONVERT parameter to specify the new location of the datafiles while using COPY or MOVE option. Step 8. Once Step 7 Completes Successfully, Switch to the PDB Container and Run the "$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql". ==- set environment to CDB ==- sqlplus / as sysdba ==- alter session set container=NCDB ==- @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql Step 9. Startup the PDB and Check the Open Mode. ==- set environment to CDB ==- sqlplus / as sysdba ==- ALTER PLUGGABLE DATABASE OPEN; ==-SELECT name, open_mode FROM v$pdbs;

One of SQL Developer’s most popular features has undergone a significant upgrade. Users can quickly define and recall delimited or Excel files to be imported to a new or existing Oracle table. Data preview and validation is provided for each column, as well as ‘best guess’ data type and date format mask mapping. This process can now be automated via the SQL Developer command line interface (SDCLI) ‘Import’ command. NOTE: This is a video only. There is no audio. Copyright © 2015 Oracle and/or its affiliates.

In the previous tutorials, we've covered creating a database and populating one, now we need to learn how to read from the database. Reading from a database is where the power of using something like SQLite over a flat file starts to make sense. While we can query the entire table, we can instead just query a single column, or even based on specific row values.

SQL: create tablespace DEMO1 datafile '/u02/tstdb1/TSTDB1/datafile/demo01.dbf' size 50M SQL: create table objects tablespace DEMO1 as select * from dba_objects; SQL: alter table objects add constraint pk_obj primary key #object_id$; SQL: create index idx_obj_name on objects#object_name$ tablespace demo1; Backup tablespace. RMAN: backup tablespace DEMO1; We need to put the DB in archivelog first Rebuild index with NOLOGGING option to simulate soft corruption later. RMAN: alter index idx_obj_name rebuild nologging; Confirm that we have datafiles that require backup because they have been affected with NOLOGGING operation. RMAN: report unrecoverable; Simulate corruption. RMAN: alter database datafile 5 offline; RMAN: restore datafile 5; RMAN: recover datafile 5; RMAN: alter database datafile 5 online; Query table with corrupted index and notice error. SQL: select count#*$ from objects where object_name like 'A%'; Let’s perform validation of datafile to check block corruption. RMAN: backup validate check logical datafile 5; Notice that we have 457 blocks marked corrupt but v$database_block_corruption view is empty. SQL: select count#*$ from v$database_block_corruption; Let’s query v$nonlogged_block view. set lines 200 set pages 999 select file#, block#, blocks,object#,reason from v$nonlogged_block; Will RMAN detect that we have corrupted blocks? RMAN: backup datafile 5; RMAN backup won’t fail due to NOLOGGING corrupt blocks and our backup will contain soft corrupted blocks. Let’s Identify corrupt segments using v$nonlogged_block view. set lines 2000 set pages 9999 col owner for a20 col partition_name for a10 col segment_name for a20 SELECT e.owner, e.segment_type, e.segment_name, e.partition_name, c.file# , greatest#e.block_id, c.block#$ corr_start_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ - greatest#e.block_id, c.block#$ + 1 blocks_corrupted FROM dba_extents e, V$NONLOGGED_BLOCK c WHERE e.file_id = c.file# AND e.block_id "= c.block# + c.blocks - 1 AND e.block_id + e.blocks - 1 := c.block# UNION SELECT s.owner, s.segment_type, s.segment_name, s.partition_name, c.file# , header_block corr_start_block# , header_block corr_end_block# , 1 blocks_corrupted FROM dba_segments s, V$NONLOGGED_BLOCK c WHERE s.header_file = c.file# AND s.header_block between c.block# and c.block# + c.blocks - 1 UNION SELECT null owner, null segment_type, null segment_name, null partition_name, c.file# , greatest#f.block_id, c.block#$ corr_start_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ - greatest#f.block_id, c.block#$ + 1 blocks_corrupted FROM dba_free_space f, V$NONLOGGED_BLOCK c WHERE f.file_id = c.file# AND f.block_id "= c.block# + c.blocks - 1 AND f.block_id + f.blocks - 1 := c.block# order by file#, corr_start_block# / This is the best outcome to get if you notice corruption errors. All errors are related to index corruption so we could fix this problem rebuilding index. alter index idx_obj_name rebuild; Simply issuing "alter index rebuild" command won't work. We should mark index unusable to drop segment before rebuilding it or just rebuild index with online option. It is better choice to mark index unusable because you don't need additional space then, but I will simply rebuild index with online option and see what will happen. SQL: alter index idx_obj_name rebuild online; Index altered. SQL: select count#*$ from objects where object_name like 'A%'; No errors... but, let's validate datafile for corruption. RMAN: backup validate check logical datafile 5; Notice "Marked Corrupt" column. Hm... 457 like before. Don't worry, this is not new corruption. These are FREE blocks which will be reused and Oracle will automatically re-format those blocks. Query the v$nonlogged_block view again as given above. We could force re-formatting creating dummy table and inserting data to dummy table. Check Doc ID 336133.1. create table s # n number, c varchar2#4000$ $ nologging tablespace DEMO1; SQL: BEGIN FOR i IN 1..1000000 LOOP INSERT /*+ APPEND */ INTO sys.s select i, lpad#'REFORMAT',3092, 'R'$ from dual; commit ; END LOOP; END; / SQL: drop table sys.s purge; Notice that we don't have corrupted blocks any more. RMAN: backup validate check logical datafile 5;

STEPS: 1. Login into Enterprise manager 2. click on server tab - tablespace 3. inside tablespace window you can found default tablespace Example Sysaux System Temp Undo Users Now we going to create our own table-space, To create a new tablespace just click create button on right hand side 4. Now enter Tablespace name, Select extent management type as: Local Type: you can select permanent , temp, undo NOTE: Permanent tablespace:- Data persistent beyond duration of a session or transcation, objects in permanent tablespaces are stored in datafile. Temporary tablespace:- It contain objects only for a session or transcation, objects are stored in temp files Undo tablespacee:- It store data permanently, it important role is to provide read consistency for SELECT statement. the ability to rollback a transcation if it is failed to commit. Status: read,write mode 5. Click on add button to add datafile give name for datafile, size then give ok Thank you for watching Blog:- http://ramprasath91.blogspot.in/

Welcome to an SQLite mini-series! SQLite, as the name suggests, is a lite version of an SQL database. SQLite3 comes as a part of the Python 3 standard library. Databases offer, typically, a superior method of high-volume data input and output over a typical file such as a text file. SQLite is a "light" version that works based on SQL syntax. SQL is a programming language in itself, but is a very popular database language. Many websites use MySQL, for example. SQLite truly shines because it is extremely lightweight. Setting up an SQLite database is nearly instant, there is no server to set up, no users to define, and no permissions to concern yourself with. For this reason, it is often used as a developmental and protyping database, but it can and is used in production. The main issue with SQLite is that it winds up being much like any other flat-file, so high volume input/output, especially with simultaneous queries, can be problematic and slow. You may then ask, what really is the difference between a typical file and sqlite. First, SQLite will let you structure your data as a database, which can easily be queried, so you get that functionality both with adding new content and calling upon it later. Each table would likely need its own file if you were doing plain files, and SQLite is all in one. SQLite is also going to be buffering your data. A flat file will require a full load before you can start querying the full dataset, SQLite files don't work that way. Finally, edits do not require the entire file to be re-saved, it's just that part of the file. This improves performance significantly. Alright great, let's dive into some SQLite. https://pythonprogramming.net/sql-database-python-part-1-inserting-database/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

Learn Database Export and Import using MySQL Workbench. Open MySQL Workbench and logged in to MySQL database server using 'root' username and password. In previous couple of videos we learned how to Create, Alter, Drop Databases and Tables and also how to Insert, Read, Update, Delete data rows using MySQL Workbench. In this lecture we will learn how to Export and Import the database using MySQL Workbench. First of all to Export the databases or tables, from top menu 'Server' select 'Data Export' Option, which opens a new window of data export settings and options. The left section on the window displays all the existing databases on our MySQL database server. When we select a database by clicking on it, it displays all the respected tables under the selected database. We can select one or multiple database check-boxes to include the database in the Export file. Under 'Export Options' section, You can change the default export path of you choice. I'll keep the default one. By selecting first option that is 'Export to Dump Project Folder'. MySQL Workbench will save the save all tables as separate SQL file under one folder. Which is useful when you will be importing or restoring the export file one by one table. I'll go ahead quickly and first save as 'Export to Dump Project Folder', MySQL Workbench displays the progress bar and log. Now, I'll again export the database using 'Export to Self-contained File' option. To demonstrate the import first I'll delete the existing 'students' table under 'mytestdb' database. Display database details by clicking on 'i' symbol, select 'tables' tab. Select and right click 'students' table, and click 'Drop Table' option, confirm and delete the table. Click 'refresh' to update the tables section and we have no table in our 'mytestdb' database. Now select the database and from 'data import' window, select 'import from dump folder. 'Load folder contents' and select only 'mytestdb' database and click start import button to import 'students' table again. Go to 'mytestdb' database information window again and click 'refresh' button to reload table list again. and the 'students' table is back.

This video describes the best architecture of the oracle after trying more than times to Oracle structure I decided to produce an animated video let's start first with the database structure on the left side you have the client here on the right side you have to serve a two-year the server side is divided in three main structures to memory the logical structure and the physical structure so let's use SQL Plus application to provide you every step up a transaction will be using Scott sample schema it is important to note that the whole string is an alias and not a database name district will be compared to this alias inside of a file called pianist named doc or this file is similar to a DNS and with up pain all the necessary detail to reach a database server locally a user process will be allocated and will validate the connection through a listener the listener will be in charge to allocate a server process the user processes da link to the server process let's now execute our first transaction for this example we will execute an update first to state that will be validated we call this step the parsing this server process sense back to confirmation of the parsing that statement with be written into their share pool and the redo log buffer an execution plan will also be created it to the fair share Paul that database book they choose fought the transaction will be read and copy into the database buffer cache only that feel implicated in that transaction will be held it to a - segment till the transaction is completed we call those copies the before image a copy of this block will be duplicated with the updated feel this copy is called me after image a confirmation will be sent to to use a process the commit statement will complete the transaction and will be written into to redo log buffer to commit statement triggers the log writer process and we'll send all statement for the current transaction into the redo log file the before image into undo segment could be then deleted went that threshold up to undo retention parameters reach alaskan from Asian will be sent to the user process went to current law kiss Paul it generates a switch lock triggering at the same time the archiver process and to log sequence number the archiver will generate and archive the file with the content of the current loc a switch up with them trigger a checkpoint process that will incriminate the checkpoint number by applying this last number into each data file header the checkpoint process with finally trigger the database writer process enright the last image from that database buffer cache into thirty people
