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

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.

SQL: Union Vs UnionAll
 
04:37
In this tutorial, you'll learn what is union & unionall PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

What a transaction is 2. The problems that might arise when tarnsactions are run concurrently 3. The different transaction isolation levels provided by SQL Server to address concurrency side effects First let us understand what is a transaction A transaction is a group of commands that change the data stored in a database. A transaction, is treated as a single unit of work. A transaction ensures that, either all of the commands succeed, or none of them. If one of the commands in the transaction fails, all of the commands fail, and any data that was modified in the database is rolled back. In this way, transactions maintain the integrity of data in a database. Example : The following transaction ensures that both the UPDATE statements succeed or both of them fail if there is a problem with one UPDATE statement. -- Transfer $100 from Mark to Mary Account BEGIN TRY BEGIN TRANSACTION UPDATE Accounts SET Balance = Balance - 100 WHERE Id = 1 UPDATE Accounts SET Balance = Balance + 100 WHERE Id = 2 COMMIT TRANSACTION PRINT 'Transaction Committed' END TRY BEGIN CATCH ROLLBACK TRANSACTION PRINT 'Transaction Rolled back' END CATCH Databases are powerful systems and are potentially used by many users or applications at the same time. Allowing concurrent transactions is essential for performance but may introduce concurrency issues when two or more transactions are working with the same data at the same time. Some of the common concurrency problems Dirty Reads Lost Updates Nonrepeatable Reads Phantom Reads We will discuss what these problems are in detail with examples in our upcomning videos One way to solve all these concurrency problems is by allowing only one user to execute, only one transaction at any point in time. Imagine what could happen if you have a large database with several users who want to execute several transactions. All the transactions get queued and they may have to wait a long time before they could get a chance to execute their transactions. So you are getting poor performance and the whole purpose of having a powerful database system is defeated if you serialize access this way. At this point you might be thinking, for best performance let us allow all transactions to execute concurrently. The problem with this approach is that it may cause all sorts of concurrency problems (i.e Dirty Reads, Lost Updates, Nonrepeatable Reads, Phantom Reads) if two or more transactions work with the same data at the same time. SQL Server provides different transaction isolation levels, to balance concurrency problems and performance depending on our application needs. Read Uncommitted Read Committed Repeatable Read Snapshot Serializable The isolation level that you choose for your transaction, defines the degree to which one transaction must be isolated from resource or data modifications made by other transactions. Depending on the isolation level you have chosen you get varying degrees of performance and concurrency problems. The table here has the list of isoltaion levels along with concurrency side effects. Isolation Level Dirty Reads Lost Update Nonrepeatable Reads Phantom Reads Read Uncommitted Yes Yes Yes Yes Read Committed No Yes Yes Yes Repeatable Read No No No Yes Snapshot No No No No Serializable No No No No If you choose the lowest isolation level (i.e Read Uncommitted), it increases the number of concurrent transactions that can be executed at the same time, but the down side is you have all sorts of concurrency issues. On the other hand if you choose the highest isolation level (i.e Serializable), you will have no concurrency side effects, but the downside is that, this will reduce the number of concurrent transactions that can be executed at the same time if those transactions work with same data. In our upcoming videos we will discuss the concurrency problems in detail with examples

BluePrism - Environmental Locking || Reality & Useful
 
23:06
Hi Friends, Today we will discuss about Environmental locking I am creating a notepad and write data into notepad with two process/bots. In this case first bot should lock the file until it releases. After releasing the first process second process picks and write the data. --------------------------------------------------------------------------------- Let's prepare the data to write into notepad 1. I have a collection having initial records 20 2. I am using loop stage to get each record from collection 3. Write record data into notepad using Action stage 'Utility - File Management' 'Append text to File' U must provide the filename and content of the file Let's run and check the data 4. We got the data in notepad and I deleted it. Till Now we didn't implemented the Locking machenism. will using Action 'Environmental Locking' internal VBO is available to use it We have three operation in that Acquire Lock - to lock the file access Query lock - Check wheather the lock is held to the file or not. Release lock - to unlock the file access 5. First we need to check the file is having lock or not. we used Query lock and passed the lock name to verify it. and it returns held lock or not and comments held lock is boolean either true or false. 6. using decision stage will lock the file or wait for release lock 7. In false case we need to lock the file using Acquire lock 8. Once the Bot work is done we need to release the lock Let's test it 9. The given file has no lock at first, So, the process started with locking system after finished it will release the lock. 10. How we know the file is locked and the process is waiting to release the lock for further steps For this we will create another process or business object and copy same code into that and run the two bots and check it. So I have same logic in Object and process Let's run and check both First process taken the lock that's why second process is wait to release the lock and keep on checking it First process done it's work and released the lock So that second process started working on it See we have two sets written in notepad.

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. 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 The following 2 transactions will result in a dead lock. 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 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 Next Video : We will discuss the criteria SQL Server uses to choose a deadlock victim

Intent - Locks in SQL Server - Part 6 Tamil
 
06:53
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg The Database Engine uses intent locks to protect placing a shared (S) lock or exclusive (X) lock on a resource lower in the lock hierarchy. Intent locks are named intent locks because they are acquired before a lock at the lower level, and therefore signal intent to place locks at a lower level. Intent locks serve two purposes: --------------------------------------------------- a) To prevent other transactions from modifying the higher-level resource in a way that would invalidate the lock at the lower level. b) To improve the efficiency of the Database Engine in detecting lock conflicts at the higher level of granularity. if a transaction has an exclusive lock on a row, SQL Server places an intent lock on the table. When another transaction requests a lock on a row in the table, SQL Server knows to check the rows to see if they have locks. If a table does not have intent lock, it can issue the requested lock without checking each row for a lock Isolation Level - https://youtu.be/ESET4zuNLoM Script for Active_Locks Function --------------------------------------------------- Create Function Active_locks () returns table return select Top 10000000 case dtl.request_session_id when -2 then 'orphaned distributed transaction' when -3 then 'deferred recovery transaction' else dtl.request_session_id end as spid, db_name(dtl.resource_database_id) as databasename, so.name as lockedobjectname, dtl.resource_type as lockedresource, dtl.request_mode as locktype, es.login_name as loginname, es.host_name as hostname, case tst.is_user_transaction when 0 then 'system transaction' when 1 then 'user transaction' end as user_or_system_transaction, at.name as transactionname, dtl.request_status from sys.dm_tran_locks dtl join sys.partitions sp on sp.hobt_id = dtl.resource_associated_entity_id join sys.objects so on so.object_id = sp.object_id join sys.dm_exec_sessions es on es.session_id = dtl.request_session_id join sys.dm_tran_session_transactions tst on es.session_id = tst.session_id join sys.dm_tran_active_transactions at on tst.transaction_id = at.transaction_id join sys.dm_exec_connections ec on ec.session_id = es.session_id cross apply sys.dm_exec_sql_text(ec.most_recent_sql_handle) as st where resource_database_id = db_id() order by dtl.request_session_id Explained in Tamil
