Table Shrinking in Oracle Database
 
14:15
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.

Career Advice : How to Become a  Database Administrator or DBA: Career Guidance animation videos

Career Advice : How to Become a Database Administrator or DBA: Career Guidance animation videos What is a database? Companies storing vast quantities of data use databases which are looked after by DBA's. This short, animated video will give you a high level overview of this role. This video is suitable for career seekers and anyone else wanting an overview/description of this role. We at funza have interviewed professionals regarded as experts in their domain and come up with this video. It focuses on providing answers to these questions: a. Overview of the role b. Requirements of the role c. Joys of the role d. Challenges of the role e. An average day f. Future prospects References: http://www.geteducated.com/career-center/detail/computer-scientist-and-database-administrator http://money.usnews.com/careers/best-jobs/database-administrator Overview: Let us understand the term Database administrator by observing an activity most of us indulge in. Let me explain the concept by mapping it to a common activity -The activity is withdrawing money from a bank. While you are withdrawing money, there are quite a few things happening in the background. Thousands of other customers may be doing the same thing, and this, is not affecting your session.and this is not affecting you in any way. ACCESS to your data is IMPORTANT where banking is concerned. You could ask your bank for past account transactions, and the bank has has an obligation to provide it. Since banking is a frequent activity, performance is taken for granted. When you are at an ATM, for example, you expect your transaction to be completed in a short period of timequickly. Now let us look at things from a banks perspective. What we are seeing here is a vast quantity of data that the bank has to store and provide its customers.. This data is stored on one or more DATABASES. But it is as we saw, it's much more than just DATA.. There is the concept of concurrency where data can be accessed by multiple customers. The concept of data security, where your data is protected The concept of performance where data is accessible in acceptable time frames. data can only be seen by you. Performance and high availability, where data is always available. Data and the this extra functionality around data are is made possible by a DBMS or data base management system. And the people responsible for managing a DBMS are DBA's or database administrators. What does a DBA Do? Now any company that needs to store vast quantities of data will use one or more databases. Thus, databases are present in a wide spectrum of companies. And not surprisingly these companies recruit DBA's to look after this data. DBAs are involved in a variety of activities: a. They install and maintain databases. b. They upgrade databases to newer versions when available c. They take backups of databases so data can be recovered if a system crashes d. They also export data across databases Monitoring databases is another component of a DBAs average day. They run tests to measure the health of a database. For example databases can fill up which means that no more information can be added. When this happens work can grind to a halt. Similarly performance can become an issue resulting in Calls to Customer Service Agents which companies never want. So this means that a DBA has to also be a problem solver DBAs also plan and implement security measures to safeguard databases. As a customer you would not want your banking or medical records to fall into wrong hands. Lastly DBAs spend a substantial amount of time in meetings with company management and vendors.

Table Compression Enhancement in Oracle Database 11g R2
 
05:00
Table Compression: Overview Oracle Database supports three methods of table compression: 1.Basic table compression 2.OLTP table compression Oracle Corporation recommends to compress all data to reduce storage costs. The Oracle database can use table compression to eliminate duplicate values in a data block. For tables with highly redundant data, compression saves disk space and reduces memory use in the database buffer cache. Table compression is transparent to database applications. The table_compression clause is valid only for heap-organized tables. The COMPRESS keyword enables table compression. The NOCOMPRESS keyword disables table compression. NOCOMPRESS is the default. With basic compression, the Oracle database compresses data at the time of performing bulk load using operations such as direct loads or CREATE TABLE AS SELECT. With COMPRESS FOR OLTP, the Oracle database compresses data during all DML operations on the table.

Oracle APEX - Make Mobile Application
 
03:51
Mobile applications are designed to run specifically on smartphone devices and hence they must be built with extremely minimal, semantic HTML that is optimized for mobile connections. Mobile applications developed with Oracle Application Express are browser-based applications that run inside the browser on the mobile device. Therefore, these applications must have a connection in order to communicate with the Oracle Database and cannot operate in a disconnected environment. Mobile devices that have HTML5 capabilities can utilize all of the capabilities that can be built into the applications, including HTML5 date-pickers, sub-types that display different keypads based on field definition, and so. Older devices will still render the application they will offer less advanced features. The major advantage of developing browser-based applications is that you only need to develop them once for the majority of mobile devices. To support mobile application development, Oracle Application Express incorporates jQuery Mobile. jQuery Mobile-based web pages use a lightweight framework that enables you to create compact and minimalistic web sites that include only a few images and CSS files. Using jQuery Mobile, these applications can run on the following mobile operating systems: iOS, Android, Blackberry, and Windows Mobile.

01 Oracle database Table lock
 
20:58
Purpose Use the LOCK TABLE statement to lock one or more tables, table partitions, or table subpartitions in a specified mode. This lock manually overrides automatic locking and permits or denies access to a table or view by other users for the duration of your operation. Some forms of locks can be placed on the same table at the same time. Other locks allow only one lock for a table. A locked table remains locked until you either commit your transaction or roll it back, either entirely or to a savepoint before you locked the table. A lock never prevents other users from querying the table. A query never places a lock on a table. Readers never block writers and writers never block readers. See Also: Oracle Database Concepts for a complete description of the interaction of lock modes COMMIT ROLLBACK SAVEPOINT Prerequisites The table or view must be in your own schema or you must have the LOCK ANY TABLE system privilege, or you must have any object privilege on the table or view. ROW SHARE ROW SHARE permits concurrent access to the locked table but prohibits users from locking the entire table for exclusive access. ROW SHARE is synonymous with SHARE UPDATE, which is included for compatibility with earlier versions of Oracle Database. ROW EXCLUSIVE ROW EXCLUSIVE is the same as ROW SHARE, but it also prohibits locking in SHARE mode. ROW EXCLUSIVE locks are automatically obtained when updating, inserting, or deleting. SHARE UPDATE See ROW SHARE. SHARE SHARE permits concurrent queries but prohibits updates to the locked table. SHARE ROW EXCLUSIVE SHARE ROW EXCLUSIVE is used to look at a whole table and to allow others to look at rows in the table but to prohibit others from locking the table in SHARE mode or from updating rows. EXCLUSIVE EXCLUSIVE permits queries on the locked table but prohibits any other activity on it. NOWAIT Specify NOWAIT if you want the database to return control to you immediately if the specified table, partition, or table subpartition is already locked by another user. In this case, the database returns a message indicating that the table, partition, or subpartition is already locked by another user. WAIT Use the WAIT clause to indicate that the LOCK TABLE statement should wait up to the specified number of seconds to acquire a DML lock. There is no limit on the value of integer. If you specify neither NOWAIT nor WAIT, then the database waits indefinitely until the table is available, locks it, and returns control to you. When the database is executing DDL statements concurrently with DML statements, a timeout or deadlock can sometimes result. The database detects such timeouts and deadlocks and returns an error.
