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.

DB: How to draw a precedence graph (rules + 3 examples)
 
07:26
From the conversation with Adi [email protected] example: You have indeed no global cycle of all transactions. But you have a cycle in T1,T2. You could indeed say, that {T1, T2} (as one entity) and {T3} is conflict serializable. Though, in this example I don't look at it in that way. My statement of "conflict serializable" / "not conflict serializable" refers to all transaction. So I mean "all transaction are conflict serializable" or "all transactions are not conflict serializable". If you're concerned about exams, you should ask your teacher in which way he wants the statement to be. Comment from TNH91 (didn't verify this content yet): "If two different transactions contain at least one write and one (read/write) on the same field, then draw an arrow from the earlier to the later."

Oracle Database Memory Serialization Control (latches & mutexes)
 
14:14
Oracle Database Memory Serialization Control (latches & mutexes) teaches Oracle DBAs the ends and outs about Oracle memory structure control. Oracle effectively creates the illusion of simultaneous memory structure manipulation. And it's our job to ensure this illusion remains a mystery to our users. To help you keep this illusion real, in this seminar I will lead you into the mysterious world of Oracle memory structure serialization control by exploring latches and mutexes: what they are, how they work, how we monitor their performance, how we tell if there is a significant problem and how we systematically diagnose the situation. I think you will soon understand why I think Oracle serialization control rocks! For details go to http://www.orapub.com/video-seminar-serialization-control PART ONE of this seminar focuses on why latches and mutexes are so important to Oracle's operations and how Oracle uses latches and mutexes in its kernel code. I also dig into how Oracle's time model relates to latching. This enables you to properly diagnosis and communicate to others why or why not latches/mutexes are a significant performance issue. Finally, I get into how Oracle increases concurrency by effectively using multiple latches of the same type to increase memory structure concurrency. It's fascinating and very important for DBAs who want to pursue a career focused on Oracle performance tuning. PART TWO begins by focusing on advanced latch spin control and detailing three ways to identify the problem latch. Then I'll begin digging deep into mutexes, including why they are important, why Oracle began using them and the acquisition algorithm. I'll even get into advanced mutex control using Oracle instance parameters. We will observe Oracle using mutexes by operating system tracing Oracle processes. It's pretty cool and key for any DBA who wants to become a performance expert. What You Will Learn In Part 1 & 2 - Why Oracle processes must ensure serial access control to Oracle memory structures - What are Oracle latches and mutexes - How Oracle latches are different from mutexes - The latch and mutex acquisition algorithms - How L&M activity relates to Oracle's time model - How to monitor for real L&M problems using Oracle's time model and an AWR report - Steps to methodically approach diagnosing and coming up with performance solutions - The differences between latches and mutexes - How Oracle implement mutexes in its library cache - How to use advanced latch spin control - What options DBAs have to influence mutex behavior L&M = Latches And Mutexes Modules Part 1: 060 Oracle Serialization Control - Part 1 1. Why the simultaneous memory structure illusion must exist and why it works so well 2 Oracle processes, L&M and memory structures, the general L&M acquisition algorithm 3 L&M time accounting and how this relates to the Oracle time model and the AWR report 4. Oracle latch specifics: concurrency limitations, child latches, multiple latches and how latches "back off." Part 2: 062 Oracle Serializatoin Control - Part 2 1. Using latch specific spin count control to your advantage and three ways to identify the problem latch 2. Why mutexes are advantageous to increase concurrency 3. Detailing the Oracle mutex algorithm 4. Advanced mutex control and observering Oracle mutex usage in detail For more information to go www.orapub.com

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.

ACID Properties in DBMS | acid properties in dbms in hindi | DBMS GATE | DBMS lectures in Hindi #106
 
05:02
Welcome to series of gate lectures by well academy In this video i am going to discuss ACID Properties in DBMS and also States of Transaction. The ACID Properties discussed in this video are in Hindi Language Atomicity − This property states that a transaction must be treated as an atomic unit, that is, either all of its operations are executed or none. There must be no state in a database where a transaction is left partially completed. States should be defined either before the execution of the transaction or after the execution/abortion/failure of the transaction. Consistency − The database must remain in a consistent state after any transaction. No transaction should have any adverse effect on the data residing in the database. If the database was in a consistent state before the execution of a transaction, it must remain consistent after the execution of the transaction as well. Durability − The database should be durable enough to hold all its latest updates even if the system fails or restarts. If a transaction updates a chunk of data in a database and commits, then the database will hold the modified data. If a transaction commits but the system fails before the data could be written on to the disk, then that data will be updated once the system springs back into action. Isolation − In a database system where more than one transaction are being executed simultaneously and in parallel, the property of isolation states that all the transactions will be carried out and executed as if it is the only transaction in the system. No transaction will affect the existence of any other transaction.

Transaction in MySQL
 
14:38
This is the eighth screen-cast in the 'Getting Started with MySQL' series. In this video we take a look at the Transaction capabilities of InnoDB Storage Engine. We learn by doing, how a number of MySQL statements can be combined to be executed as a single Unit. We learn about how to commit explicitly in MySQL, how to Rollback, and Rollback to a specific savepoint. Further we take a look at how MySQL solves three of the common problems in Transactions: Dirty Read, Non-Repeatable Read and Phantom Read. This is by studying the importance of a MySQL variable named 'tx_isolation' whose value (READ-UNCOMMITTED/READ-COMMITTED/REPEATABLE-READ/SERIALIZABLE) decides how the changes made by another Transaction on an InnoDB Table gets displayed within a Transaction on the same Table
