Table Shrinking in Oracle Database
1.Shrink the Table: Shrinking is started from 10g. In this method I’m using user u1 and table name sm1. Now I’m deleting some rows in sm1 COUNT ---------- 1048576 Table sm1 has 1048576 rows. [email protected]: delete from sm1 where deptno=10; 262144 rows deleted. I deleted above number of rows. Rows COUNT ---------- 786432 And I’m giving commit [email protected]: commit; Commit complete. So now we have 786432 rows in sm1 table. Now see the following command [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ------ ---------- ---------- U1 U1TS SM1 TABLE 29 mb 3712 44 After I deleted some rows in sm1 table still above result showing same values, so now our duty is shrink this table. This is done by following 2 ways, i By using COMPACT key word: In this method shrinking is done in two phases. In the first phase all fragmented space are just defragmented, but still the High Water Mark is persist with last used block only. That mean used free blocks are not de allocated and HWM is not updated here. Issue the following command before use shrink command. [email protected] alter table sm1 enable row movement; Table altered. There is particular use with above command, when we shrink the table all rows are moves to contiguous blocks, so here row movement should be done. By default the row movement is disabled for any table, so above command enabled the row movement. Then execute shrink command now. [email protected]: alter table sm1 shrink space compact; Table altered. Now see the space of table by using below command. [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ------ ---------- ---------- U1 U1TS SM1 TABLE 29 mb 3712 44 So here seems nothing happened with above shrink command, but internally the fragmented space is defragmented. But the high water mark is not updated, used free blocks are also not de allocated. For de allocating the used blocks we have to execute below command. This is the second phase. [email protected]: alter table sm1 shrink space; Table altered. Now see the space by using below command. [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ---------- ---------- ---------- U1 U1TS SM1 TABLE 20.8125 mb 2664 36 So now the space of sm1 table is reduced. Note: Actually the alter table sm1 shrink space command will complete these two phases of the shrinking of table at a time. But here we done shrink process in two phases because when we use alter table sm1 shrink space command the table locked temporarily some time period, during this period users unable to access the table. So if we use alter table sm1 shrink space compact command the table is not locked but space is defragmented. When we not in business hours issue the second phase shrink command then users are won’t get any problem. ii Because of above method the table dependent objects are goes to invalid state, to overcome this problem we have to use below command. [email protected]: alter table sm1 shrink space cascade; Table altered. The above command also shrinks the space of all dependent objects. We also do this in two phases like above two phases. See the below command. [email protected]: alter table sm1 shrink space compact cascade; Table altered. And then [email protected]: alter table sm1 shrink space cascade; Table altered.

SQL Server 34 - How to Create and Drop Indexes
Creating indexes is a very easy task, but before you go creating indexes on everything, you need to know that some columns are indexed by default. Specifically, any column that is labeled as the PRIMARY KEY or UNIQUE are indexed by default. That means that if you have a UNIQUE column, you do not need to worry about adding an INDEX to it. The columns that you will want to pay special attention to are any foreign keys or columns that you are going to use very frequently. We are going to create an index on our SpeciesID column in our Animals table. This is a foreign key that I'm likely going to use very frequently. CREATE INDEX IX_AnimalsSpecies ON Animals (SpeciesID); The syntax is very similar to CREATE TABLE in that you say CREATE INDEX followed by an index name. The IX_ is a prefix that is sometimes conventionally used to name indexes. Next, we have the table name, and then we have something to describe the column. That way if you see IX_AnimalsSpecies, you automatically know it is talking about an Index for the Animals table that is on the column dealing with the species. To get rid of this index, use this: DROP INDEX IX_AnimalsSpecies; Which is also very similar to how we drop a table. Now, you can also create an INDEX on multiple columns if you are going to use them together very often. The way you do that is just add another column after a comma inside of the () in the index columns. For example: CREATE INDEX IX_AnmialsContact ON Animals (Name, ContactEmail); One other thing I wanted to show you is that you can actually create a UNIQUE Index by adding the keyword in: CREATE UNIQUE INDEX IX_Species ON Species (Species); This should only be used if every value for a column is labeled unique…In fact, it forces every row to be unique. Remember though that if a column is labeled UNIQUE, it is indexed by default...So this is not needed in this situation. In the next video we will discuss in more detail whether you want to use the UNIQUE Constraint create a UNIQUE index. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

How to Reset MySQL Autoincrement
Follow this step by step guide to reset the auto-increment option from mysql. The reset helps to stream line the database as you can type in the number that was previously used. Don't forget to check out our site http://howtech.tv/ for more free how-to videos! http://youtube.com/ithowtovids - our feed http://www.Facebook.com/howtechtv - join us on Facebook https://plus.google.com/103440382717658277879 - our group in Google+ Introduction In this tutorial, we will show you how to reset the Auto increment field in MySQL. Mysql Auto-increment allows a unique number to be generated when a new record is inserted into a table. The function allows you to automatically add 1 to the previous record if you enter a new value. You can always reset Mysql auto increment so that when you delete a record your data does show an uneven picture. Step 1 -- Selecting records Over here, we will be using the MySQL instance called SQL Yog. Just consider this table having the names of animals and the serial number, in this example the Mysql auto increment function is in operation. If we delete any of the record from the table, that particular ID value will not be associated with any other field. This is because the auto number field will not change its order according to the changes made in the table. Step 2 -- Selecting the column To fix this problem, you can simply drop the column and make it once again. For that, we will write the alter table query along with the table name and specify the id column with the drop keyword. When we run the query and fetch all the records from the table, you will notice that the ID field has been deleted. Now let's type the Alter Table query and give the table name which in our case is animals. Next, we will include the ADD keyword along with the column name which is ID in this case. Next, we will specify the data type, which would be Medium Integer in this case and after that, let's add the Not Null and Auto increment Constraints along with the Primary key. With that done, let's run the query and fetch all the records from the database. With that done, you will notice that all Auto increment field has been reset, and all the ID's are now in order. And in this manner you can reset Mysql auto increment.

File system
In computing, a file system (or filesystem) is used to control how data is stored and retrieved. Without a file system, information placed in a storage area would be one large body of data with no way to tell where one piece of information stops and the next begins. By separating the data into individual pieces, and giving each piece a name, the information is easily separated and identified. Taking its name from the way paper-based information systems are named, each piece of data is called a "file". The structure and logic rules used to manage the groups of information and their names is called a "file system". There are many different kinds of file systems. Each one has different structure and logic, properties of speed, flexibility, security, size and more. Some file systems have been designed to be used for specific applications. For example, the ISO 9660 file system is designed specifically for optical discs. This video is targeted to blind users.

He is an active member of the free and open source software community, especially in Australia. ABSTRACT Part 1 - Introduction to MySQL Cluster The NDB storage engine (MySQL Cluster) is a high-availability storage engine for MySQL. It provides synchronous replication between storage nodes and many mysql servers having a consistent view of the database. In 4.1 and 5.0 it's a main memory database, but in 5.1 non-indexed attributes can be stored on disk. NDB also provides a lot of determinism in system resource usage. I'll talk a bit about that. Part 2 - New features...
