Identifying & Locking default (service) accounts in Oracle
 
01:37
Oracle default installation comes up with several database accounts that're opened and have escalated privileges. Oracle database installs with a number of default database user accounts. Upon successful installation of the database, the Database Configuration Assistant automatically locks and expires most default database user accounts. If you perform a manual (without using Database Configuration Assistant) installation of Oracle Database, then no default database users are locked upon successful installation of the database server. Or, if you have upgraded from a previous release of Oracle Database, you might have default accounts from earlier releases. Left open in their default states, these user accounts can be exploited, to gain unauthorized access to data or disrupt database operations. You should lock and expire all default database user accounts. Oracle Database provides SQL statements to perform these operations.

Solving Performance Problems on Oracle DB
 
28:11
Solving Performance Problems on Oracle DB Matthew Vegh - Embarcadero Thursday, June 26, 2014 - 11am DBAs and database developers regularly spend a lot of time tracking down and resolving performance issues on the database servers they are responsible for; it can be very difficult, frustrating, and expensive. Given the complex interactions of applications, users and databases, new performance issues can arise almost as fast as old ones can be addressed. This session will simulate common performance problems on an Oracle server and then both identify those problems and provide effective solutions. Matthew Vegh is a Software Architect at Embarcadero Technologies for the Embarcadero DB Power Studio family of products and has been with the company for the better part of a decade. He has over 15 years of development experience with a wide range of technologies and a definite preference for database tooling.

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

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

PL/SQL: Object Type
 
08:31
In this tutorial, you'll learn what is a object type in sql/plsql 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.
