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.

ACID Is So Yesterday: Maintaining Data Consistency with Sagas
 
43:29
Chris Richardson, Software Craftsman, Eventuate, Inc The services in a microservice architecture must be loosely coupled and so cannot share database tables. What’s more, two-phase commit (aka a distributed transaction) is not a viable option for modern applications. Consequently, a microservice-based application must use so-called sagas to maintain data consistency between services. In this presentation, you will learn how sagas work and how they differ from traditional ACID transactions. You will also learn how to design and implement sagas for your applications.

Simplified DBA-019-Data Concurrency and Locks
 
03:56
DATA CONCURRENCY More than one user connections ( session ) can access same data. For example user1 and user2 can view same employee information at the same time. But not two users can modify same data in one time. This is maintained by oracle lock mechanism. Before the database allows a session to modify data, the session must first lock the data that is being modified. A lock gives the session exclusive control over the data so that no other transaction can modify the locked data until the lock is released. Transactions can lock individual rows of data, multiple rows, or even entire tables. Oracle Database supports both manual and automatic locking. Automatically acquired locks always choose the lowest possible level of locking to minimize potential conflicts with other transactions. Demo: User1 is modifying an employee. User1 session will acquire a lock on the row. Same time user2 is trying to modify same employee. Since User1 has acquired lock, user2 has to wait until user1 releases the lock. Manual locking is possible. A user can place a lock manually as follows: LOCK TABLE mytable1 IN EXCLUSIVE MODE; With the preceding statement, any other transaction that tries to update a row in the locked table must wait until the transaction that issued the lock request completes. EXCLUSIVE is the strictest lock mode. The following are the other lock modes: ROW SHARE: Permits concurrent access to the locked table but prohibits sessions from locking the entire table for exclusive access ROW EXCLUSIVE: Is the same as ROW SHARE, but also prohibits locking in SHARE mode. The ROW EXCLUSIVE locks are automatically obtained when updating, inserting, or deleting data. ROW EXCLUSIVE locks allow multiple readers and one writer. SHARE: Permits concurrent queries but prohibits updates to the locked table. A SHARE lock is required (and automatically requested) to create an index on a table. However, online index creation requires a ROW SHARE lock that is used when building the index.

Transactions Across Datacenters - Ryan Barrett For those who are attending Google I/O 2009(http://code.google.com/io/), these video are an opportunity to hear from some of the speakers in advance. The speakers introduce their topic and provide a preview of one or more topics that will be covered in their talks. If you work on distributed systems, you try to design your system to keep running if any single machine fails. If you're ambitious, you might extend this to entire racks, or even more inconvenient sets of machines. However, what if your entire datacenter falls off the face of the earth? This talk will examine how current large scale storage systems handle fault tolerance and consistency, with a particular focus on the App Engine datastore. We'll cover techniques such as replication, sharding, two phase commit, and consensus protocols (e.g. Paxos), then explore how they can be applied across datacenters.

Oracle Database or simply called as Oracle is a multi-model database management system produced and marketed by Oracle Corporation. Oracle is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database workloads. Oracle has schemas and tables, like most other databases, but its structure is optimized to work best with Oracle software. An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications. Oracle databases are used for practically all corporation level applications. Thus, Oracle databases dominate the banking industry. Ten of the world's top banks use Oracle databases to conduct their business. Oracle database has the ability to manage multiple databases using a two-phase commit protocol. Oracle supports cursors, which helps to make programming easier. Oracle made easy to deploy mapping, geocoding and routing services directly from data stored in Oracle and integrate them into company applications and processes.

Thank you friends for watching the video. Please Like the video if it has helped you in any way & do subscribe to the channel. This video contains the detailed discussion of clustered indexing in dbms with example. Detail explanation of Clustered Indexing, Example of Clustered Indexing, How Clustered indexing works in dbms,Need of Clustered Indexing, Where Clustered Indexing is used,Advantages of Clustered Indexing,Properties of Clustered Indexing in dbms, Properties of single level indexing, Questions of Clustered Indexing,Numericals on Clustered Indexing for gate exam, How Clustered indexing works on file is explained. CLUSTERED INDEXING: - i)Main file will be ordered on some non-key attributes ii)No of entries in the index file = no of unique values of the attribute on which indexing is done. iii)It is the example of Sparse as well as dense indexing Block access required will be greater than equal to log2n +1, where n is no of block acquired by Index file.

Thank you friends for watching the video. Please Like the video if it has helped you in any way & do subscribe to the channel. This video discuss the Types of Indexing in database in hindi. Important topic of database Indexing like need of indexing in database management indexing, Why we do indexing in files in database, How we do indexing in dbms, Types of indexing, Methods of Indexing, Advantages of Indexing,How to access a file fast in database, Single level Indexing in database file, Multilevel indexing in database file structure in dbms,Primary Indexing in database, Clustered Indexing in database,Secondary Indexing file in dbms, Advantages of using single level Indexing in database are discussed. Single level index: This means we create index file for the main file, and then stop the process. Multiple level index:This means, we further index the index file and keep repeating the process until we get one block.Multi-level Index helps in breaking down the index into several smaller indices in order to make the outermost level so small that it can be saved in a single disk block-0, which can easily be accommodated anywhere in the main memory. A.) PRIMARY INDEXING- i) Main file is always sorted according to primary key. ii) Indexing is done on Primary Key, therefor called as primary indexing B.) CLUSTERED INDEXING: - i) Main file will be ordered on some non-key attributes ii) No of entries in the index file = no of unique values of the attribute on which indexing is done. iii) It is the example of Sparse as well as dense indexing C.) SECONDARY INDEXING- i) Most common scenarios, Suppose that we already have a primary indexing on primary key, but there are frequent query on some other attributes , so we may decide to have one more index file with some other attribute. ii) Main file is ordered according to the attribute on which indexing is done(unordered). iii) Secondary indexing can be done on key or non-key attribute. iii) It is an example of dense indexing.
