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.

03 Dead Lock in oracle database
 
11:37
DML Locks DML locks or data locks guarantee the integrity of data being accessed concurrently by multiple users. DML locks help to prevent damage caused by interference from simultaneous conflicting DML or DDL operations. By default, DML statements acquire both table-level locks and row-level locks. The reference for each type of lock or lock mode is the abbreviation used in the Locks Monitor from Oracle Enterprise Manager (OEM). For example, OEM might display TM for any table lock within Oracle rather than show an indicator for the mode of table lock (RS or SRX). Row Locks (TX) Row-level locks serve a primary function to prevent multiple transactions from modifying the same row. Whenever a transaction needs to modify a row, a row lock is acquired by Oracle. There is no hard limit on the exact number of row locks held by a statement or transaction. Also, unlike other database platforms, Oracle will never escalate a lock from the row level to a coarser granular level. This row locking ability provides the DBA with the finest granular level of locking possible and, as such, provides the best possible data concurrency and performance for transactions. The mixing of multiple concurrency levels of control and row level locking means that users face contention for data only whenever the same rows are accessed at the same time. Furthermore, readers of data will never have to wait for writers of the same data rows. Writers of data are not required to wait for readers of these same data rows except in the case of when a SELECT... FOR UPDATE is used. Writers will only wait on other writers if they try to update the same rows at the same point in time. In a few special cases, readers of data may need to wait for writers of the same data. For example, concerning certain unique issues with pending transactions in distributed database environments with Oracle. Transactions will acquire exclusive row locks for individual rows that are using modified INSERT, UPDATE, and DELETE statements and also for the SELECT with the FOR UPDATE clause. Modified rows are always locked in exclusive mode with Oracle so that other transactions do not modify the row until the transaction which holds the lock issues a commit or is rolled back. In the event that the Oracle database transaction does fail to complete successfully due to an instance failure, then Oracle database block level recovery will make a row available before the entire transaction is recovered. The Oracle database provides the mechanism by which row locks acquire automatically for the DML statements mentioned above. Whenever a transaction obtains row locks for a row, it also acquires a table lock for the corresponding table. Table locks prevent conflicts with DDL operations that would cause an override of data changes in the current transaction. Table Locks (TM) What are table locks in Oracle? Table locks perform concurrency control for simultaneous DDL operations so that a table is not dropped in the middle of a DML operation, for example. When Oracle issues a DDL or DML statement on a table, a table lock is then acquired. As a rule, table locks do not affect concurrency of DML operations. Locks can be acquired at both the table and sub-partition level with partitioned tables in Oracle. A transaction acquires a table lock when a table is modified in the following DML statements: INSERT, UPDATE, DELETE, SELECT with the FOR UPDATE clause, and LOCK TABLE. These DML operations require table locks for two purposes: to reserve DML access to the table on behalf of a transaction and to prevent DDL operations that would conflict with the transaction. Any table lock prevents the acquisition of an exclusive DDL lock on the same table, and thereby prevents DDL operations that require such locks. For example, a table cannot be altered or dropped if an uncommitted transaction holds a table lock for it. A table lock can be held in any of several modes: row share (RS), row exclusive (RX), share (S), share row exclusive (SRX), and exclusive (X). The restrictiveness of a table lock's mode determines the modes in which other table locks on the same table can be obtained and held.

Transactions and Concurrency Control Patterns by Vlad Mihalcea
 
45:29
Transactions and Concurrency Control are very of paramount importance when it comes to enterprise systems data integrity. However, this topic is very tough since you have to understand the inner workings of the database system, its concurrency control design choices (e.g. 2PL, MVCC), transaction isolation levels and locking schemes. In this presentation, I'm going to explain what data anomalies can happen depending on the transaction isolation level, with references to Oracle, SQL Server, PostgreSQL, and MySQL. I will also demonstrate that database transactions are not enough, especially for multi-request web flows. For this reason, I'm going to present multiple application-level transaction patterns based on both optimistic and pessimistic locking mechanisms.

Difference between blocking and deadlocking
 
06:52
deadlock vs blocking sql server In this video we will discuss the difference between blocking and deadlocking. This is one of the common SQL Server interview question. Let us understand the difference with an example. SQL Script to create the tables and populate them with test data Create table TableA ( Id int identity primary key, Name nvarchar(50) ) Go Insert into TableA values ('Mark') Go Create table TableB ( Id int identity primary key, Name nvarchar(50) ) Go Insert into TableB values ('Mary') Go Blocking : Occurs if a transaction tries to acquire an incompatible lock on a resource that another transaction has already locked. The blocked transaction remains blocked until the blocking transaction releases the lock. Example : Open 2 instances of SQL Server Management studio. From the first window execute Transaction 1 code and from the second window execute Transaction 2 code. Notice that Transaction 2 is blocked by Transaction 1. Transaction 2 is allowed to move forward only when Transaction 1 completes. --Transaction 1 Begin Tran Update TableA set Name='Mark Transaction 1' where Id = 1 Waitfor Delay '00:00:10' Commit Transaction --Transaction 2 Begin Tran Update TableA set Name='Mark Transaction 2' where Id = 1 Commit Transaction Deadlock : Occurs when two or more transactions have a resource locked, and each transaction requests a lock on the resource that another transaction has already locked. Neither of the transactions here can move forward, as each one is waiting for the other to release the lock. So in this case, SQL Server intervenes and ends the deadlock by cancelling one of the transactions, so the other transaction can move forward. Example : Open 2 instances of SQL Server Management studio. From the first window execute Transaction 1 code and from the second window execute Transaction 2 code. Notice that there is a deadlock between Transaction 1 and Transaction 2. -- Transaction 1 Begin Tran Update TableA Set Name = 'Mark Transaction 1' where Id = 1 -- From Transaction 2 window execute the first update statement Update TableB Set Name = 'Mary Transaction 1' where Id = 1 -- From Transaction 2 window execute the second update statement Commit Transaction -- Transaction 2 Begin Tran Update TableB Set Name = 'Mark Transaction 2' where Id = 1 -- From Transaction 1 window execute the second update statement Update TableA Set Name = 'Mary Transaction 2' where Id = 1 -- After a few seconds notice that one of the transactions complete -- successfully while the other transaction is made the deadlock victim Commit Transaction Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/difference-between-blocking-and.html

SCPT 40 : Types of DDL Locks in Oracle
 
11:17
The two basic types of locks are DML (table) locks, and DDL (dictionary) locks. A DDL lock protects the definition of a schema object while the object is referenced in a DDL operation. Oracle automatically acquires a DDL lock to prevent other DDL operations from referencing or altering the same object.

Oracle 11g Lock Monitoring with Read Committed Transaction Isolation Level Brief Explanation
 
12:24
Oracle 11g memiliki 2 jenis transaction isolation level yaitu Read Committed dan Serializable. Secara default transaction isolation pada Oracle adalah Read Committed, yaitu ketika sebuah session melakukan Insert/Update/Delete pada sebuah data dilanjutkan dengan commit maka session lain akan secara otomatis membaca data yang sama. Terdapat Row Level Lock (TX) dan Table Level Lock (TM). Video ini memberikan contoh jelas tentang transaksi yang terjadi ketika proses locking terjadi.

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.

Neither of the transactions here can move forward, as each one is waiting for the other to release the lock. When deadlocks occur, SQL Server will choose one of processes as the deadlock victim and rollback that process, so the other process can move forward. The transaction that is chosen as the deadlock victim will produce the following error. Msg 1205, Level 13, State 51, Line 1 Transaction (Process ID 57) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

Update - Locks in SQL Server - Part 4 Tamil
 
07:42
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Update (U) locks prevent a common form of deadlock. In a repeatable read or serializable transaction, the transaction reads data, acquiring a shared (S) lock on the resource (page or row), and then modifies the data, which requires lock conversion to an exclusive (X) lock. If two transactions acquire shared-mode locks on a resource and then attempt to update data concurrently, one transaction attempts the lock conversion to an exclusive (X) lock. The shared-mode-to-exclusive lock conversion must wait because the exclusive lock for one transaction is not compatible with the shared-mode lock of the other transaction; a lock wait occurs. The second transaction attempts to acquire an exclusive (X) lock for its update. Because both transactions are converting to exclusive (X) locks, and they are each waiting for the other transaction to release its shared-mode lock, a deadlock occurs. To avoid this potential deadlock problem, update (U) locks are used. Only one transaction can obtain an update (U) lock to a resource at a time. If a transaction modifies a resource, the update (U) lock is converted to an exclusive (X) lock.

sql server lost update problem

Lost update problem happens when 2 transactions read and update the same data. Let's understand this with an example. Consider the following 2 transactions - Transaction 1 and Transaction 2. Transaction 1 starts first, and it is processing an order for 1 iPhone. It sees ItemsInStock as 10. At this time Transaction 2 is processing another order for 2 iPhones. It also sees ItemsInStock as 10. Transaction 2 makes the sale first and updates ItemsInStock with a value of 8. At this point Transaction 1 completes the sale and silently overwrites the update of Transaction 2. As Transaction 1 sold 1 iPhone it has updated ItemsInStock to 9, while it actually should have updated it to 7. Example : The lost update problem example. Open 2 instances of SQL Server Management studio. From the first window execute Transaction 1 code and from the second window, execute Transaction 2 code. Transaction 1 is processing an order for 1 iPhone, while Transaction 2 is processing an order for 2 iPhones. At the end of both the transactions ItemsInStock must be 7, but we have a value of 9. This is because Transaction 1 silently overwrites the update of Transaction 2. This is called the lost update problem. -- Transaction 1 Begin Tran Declare @ItemsInStock int Select @ItemsInStock = ItemsInStock from tblInventory where Id=1 -- Transaction takes 10 seconds Waitfor Delay '00:00:10' Set @ItemsInStock = @ItemsInStock - 1 Update tblInventory Set ItemsInStock = @ItemsInStock where Id=1 Print @ItemsInStock Commit Transaction -- Transaction 2 Begin Tran Declare @ItemsInStock int Select @ItemsInStock = ItemsInStock from tblInventory where Id=1 -- Transaction takes 1 second Waitfor Delay '00:00:1' Set @ItemsInStock = @ItemsInStock - 2 Update tblInventory Set ItemsInStock = @ItemsInStock where Id=1 Print @ItemsInStock Commit Transaction Both Read Uncommitted and Read Committed transaction isolation levels have the lost update side effect. Repeatable Read, Snapshot, and Serializable isolation levels does not have this side effect. If you run the above Transactions using any of the higher isolation levels (Repeatable Read, Snapshot, or Serializable) you will not have lost update problem. The repeatable read isolation level uses additional locking on rows that are read by the current transaction, and prevents them from being updated or deleted elsewhere. This solves the lost update problem. For both the above transactions, set Repeatable Read Isolation Level. Run Transaction 1 first and then a few seconds later run Transaction 2. Transaction 1 completes successfully, but Transaction 2 competes with the following error. Transaction was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. Once you rerun Transaction 2, ItemsInStock will be updated correctly as expected.

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

Lock Compatibility in SQL Server
 
10:14
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Lock compatibility controls whether multiple transactions can acquire locks on the same resource at the same time. If a resource is already locked by another transaction, a new lock request can be granted only if the mode of the requested lock is compatible with the mode of the existing lock. If the mode of the requested lock is not compatible with the existing lock, the transaction requesting the new lock waits for the existing lock to be released or for the lock timeout interval to expire.For example, no lock modes are compatible with exclusive locks. While an exclusive (X) lock is held, no other transaction can acquire a lock of any kind (shared, update, or exclusive) on that resource until the exclusive (X) lock is released. Alternatively, if a shared (S) lock has been applied to a resource, other transactions can also acquire a shared lock or an update (U) lock on that item even if the first transaction has not completed. However, other transactions cannot acquire an exclusive lock until the shared lock has been released.

Improving foreign key concurrency
 
43:17
To lock and not to block Row locking is a mechanism that lets Postgres maintain strict consistency in certain database constraints, such as foreign keys. However, Postgres has historically only provided share and exclusive row locking, which I'll show to have significant drawbacks for concurrency. To solve the concurrency problem, two new row lock types are being introduced in release 9.2: SELECT FOR KEY SHARE and SELECT FOR KEY UPDATE. In this talk I'll explain how this new locking came to be, how it works, and how it helps significantly improve concurrency in applications.
