Webinar: All About the Function Result Cache
 
01:08:47
Presented by Steven Feuerstein, Oracle Corporation The function result cache, added in Oracle Database 11g, offers developers a way to dramatically reduce the amount of time it takes to retrieve data requested repeatedly by database sessions (specifically, when the same rows of a table are fetched much more frequently than they are changed). This cache is stored in the SGA, shared across all sessions in the instance, and automatically purged of "dirty data" by the Oracle Database. Every application running on 11.1 or higher should be taking advantage of this feature. Best of all, there is minimal impact on your code to start using this feature.

In this short episode, I show you how you can cache database queries for a certain period of time. This is really nice when you have data you know won't change during x period of time, because once it's in cache, Laravel knows to automatically skip the database query and immediately deliver the requested content from RAM. Super fast, super easy.

Oracle SQL Tuning - How to Read Execution Plans (Explain Plan)
 
13:39
In this free tutorial you will learn how to generate and read (interpret) an execution plan in Oracle Databases. See more FREE Oracle Tuning tutorials at http://skillbuilders.com/free-oracle-tutorials. Understanding what the Oracle Database does with your SQL is essential to tuning - and the execution plan is the key. Oracle Certified Master DBA John Watson will provide a brief introduction (4 minutes) - which includes John's tuning methodology, then demonstrate EXPLAIN PLAN, SQL*Plus AUTOTRACE and DBMS_XPLAN.DISPLAY_CURSOR. In the tutorial, John will teach you: - How to read an execution plan - Find the 1st step in the plan - Decipher the order of the steps in the plan - That EXPLAIN PLAN can be very misleading Prerequisites: To get the most from this tutorial, you should: 1 Know how to code SQL 2 Be familiar with SQL*Plus 3 Know - in very general terms - what an execution plan is. 4 Have a basic understanding of the Library Cache (this is where Oracle Database stores parsed SQL statements) 5 Have a basic understanding of the Cost Based Optimizer (this is the part of the database that parses your SQL, creates an execution plan. Hopefully the correct - most efficient - plan).

Bulk processing (FORALL and BULK COLLECT), along with the function result cache, are the "big ticket" items when it comes to performance optimization with PL/SQL. But there's still more we can do to tweak our code for even better response times for our users. This third webast in the series starts with the automatic compiler optimization, showcases the extraordinary speediness of PGA data manipulation (a.k.a., package variables), and demonstrates the effect of the simple NOCOPY hint. We finish up with an introduction to pipelined table functions and some thoughts on optimizing your algorithms.

Understanding And Resolving Oracle Free Buffer Wait Contention - Seminar Intro
 
06:19
This is the introduction to my video seminar, Understanding And Resolving Oracle Free Buffer Wait Contention. Free buffer waits is one of the most feared of all Oracle wait events. It requires just the right workload mix and configuration to appear. When it does appear, it affects the entire application. As Oracle DBAs, our job is to regain control of the situation and restore application performance. But it is complicated and making the wrong move can make the situation even worse! So, how do you quickly improve performance with a clear understanding of the situation? That's the focus of this seminar. This seminar is designed to take you on a journey. The journey starts with Craig clearly explaining what a free buffer wait is. Then he delves into Oracle's buffer cache, focusing on the least recently used (LRU) lists and the associated algorithms. Craig even role plays as an Oracle foreground process and an Oracle buffer header, locking the details into your brain. Now the details brought together making the cause and effect clear so the presented solutions make perfect sense! Taking it further, two solutions are implemented and the results analyzed. Join Oracle ACE Director Craig Shallahamer as he take you on an unforgettable journey into the Oracle buffer cache zeroing in on understanding and resolving Oracle free buffer waits.

For example, on my machine I have 400,000 records in tblProducts table 600,000 records in tblProductSales tables The following query, returns, the list of products that we have sold atleast once. This query is formed using sub-queries. When I execute this query I get 306,199 rows in 6 seconds Select Id, Name, Description from tblProducts where ID IN ( Select ProductId from tblProductSales ) At this stage please clean the query and execution plan cache using the following T-SQL command. CHECKPOINT; GO DBCC DROPCLEANBUFFERS; Go DBCC FREEPROCCACHE; GO Now, run the query that is formed using joins. Notice that I get the exact same 306,199 rows in 6 seconds. Select distinct tblProducts.Id, Name, Description from tblProducts inner join tblProductSales on tblProducts.Id = tblProductSales.ProductId Please Note: I have used automated sql script to insert huge amounts of this random data. Please watch Part 61 of SQL Server tutorial, in which we have discussed about this automated script. According to MSDN, in some cases where existence must be checked, a join produces better performance. Otherwise, the nested query must be processed for each result of the outer query. In such cases, a join approach would yield better results. The following query returns the products that we have not sold atleast once. This query is formed using sub-queries. When I execute this query I get 93,801 rows in 3 seconds Select Id, Name, [Description] from tblProducts where Not Exists(Select * from tblProductSales where ProductId = tblProducts.Id) When I execute the below equivalent query, that uses joins, I get the exact same 93,801 rows in 3 seconds. Select tblProducts.Id, Name, [Description] from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId where tblProductSales.ProductId IS NULL In general joins work faster than sub-queries, but in reality it all depends on the execution plan that is generated by SQL Server. It does not matter how we have written the query, SQL Server will always transform it on an execution plan. If sql server generates the same plan from both queries, we will get the same result. I would say, rather than going by theory, turn on client statistics and execution plan to see the performance of each option, and then make a decision. In a later video session we will discuss about client statistics and execution plans in detail.

Demonstrating Oracle DB Elapsed Time and Wall Time With Parallel Query
 
03:37
Is it really true? In my recent postings I wrote that when using parallel query a SQL statement's wall time is roughly equal to its elapsed time divided by the number of parallel query slaves. To check I ran an experiment and posted the results. The results are both obvious and illuminating. If you don't want to read but just sit on the couch and watch a video, you're in luck! I created a special video clip demonstrating what I wrote about. The main video clip is from my OraPub Online Institute video seminar, Tuning Oracle Using An AWR Report - Part 1.

Held in June 2018 Christopher Jones, Dan McGhan and Anthony Tuininga review some of the latest features of the node-oracledb Node.js driver and answer user's questions, and in particular offer an overview of the new APIs and demonstrate how they work. Native support for Oracle Database Continuous Query Notification (CQN) has landed in the node-oracledb master branch on GitHub. CQN allows an application to register queries with the database so the database can notify the application if the objects in the query or query result change. In this office hours, we'll provide an overview of the new APIs and demonstrate how they work. AskTOM Office Hours offers free, monthly training and tips on how to make the most of Oracle Database, from Oracle product managers, developers and evangelists. https://asktom.oracle.com/ Oracle Developers portal: https://developer.oracle.com/ Sign up for an Oracle Cloud trial: https://cloud.oracle.com/en_US/tryit music: bensound.com

PL/SQL tutorial | Stored Procedure in Oracle Database 11g Complete guide
 
23:55
Learn in depth about stored procedure in oracle,usage of SP in Database. Creating Stored Procedure using in, out ,in/out parameter and handling exception inside with example. Stored Procedure in Oracle, Stored Procedure in PL/SQL, Oracle Stored Procedure, PL/SQL Stored Procedure, What is Stored Procedure in pl/sql, How to use Stored Procedure in pl/sql, How to write a Stored Procedure in oracle, How to create Stored Procedure in pl/sql, Parameterized stored procedure in pl/sql, Benefit of using stored procedure in oracle, Advantages of Using Stored Procedures: Maintainability (because scripts are in one location, updates and tracking of dependencies based on schema changes becomes easier) Can be tested independent of the application Isolation of Business Rules,(Having Stored Procedures in one location means that there’s no confusion of having business rules spread over potentially disparate code files in the application) Speed / Optimization ( Stored procedures are cached on the server Execution plans for the process are easily reviewable without having to run the application) Utilization of Set-based Processing (The power of SQL is its ability to quickly and efficiently perform set-based processing on large amounts of data; the coding equivalent is usually iterative looping, which is generally much slower) Security ( Limit direct access to tables via defined roles in the database, provide an “interface” to the underlying data structure so that all implementation and even the data itself is shielded. Securing just the data and the code that accesses it is easier than applying that security within the application code itself ). Drawbacks to Using Stored Procedures: Limited Coding Functionality Stored procedure code is not as robust as app code, particularly in the area of looping (not to mention that iterative constructs, like cursors, are slow and processor intensive) Portability issue for complex and large Stored Procedure. Testing :Any data errors in handling Stored Procedures are not generated until runtime Cost :Stored Procedure development could potentially require a dedicated database developer. Some businesses will not allow developers access to the database at all, requiring instead a separate DBA. Alternatives to Stored Procedures: In-line or Parameterized Queries (These are written within the application code itself) Object Relational Mapping (ORM) (Provides an abstraction to the database without having to manually write data ) Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

Understanding And Resolving Oracle CBC Wait/Latch Contention - Introduction
 
07:10
Understanding And Resolving Oracle CBC Wait/Latch Contention When a server process needs to access a buffer it must access the cache buffer chain (CBC) structure to determine if the buffer is already in the buffer cache. With just the right workload mix, performance can be a problem. Learning about the relevant Oracle internals and how to diagnose and solve CBC performance problems is what this seminar is all about.

The Optimum Histogram Utility DEMO 1 - Maximize Oracle Performance and SQL Execution Efficiency
 
13:54
Demonstration of the influence of the Optimum Histogram utilities on the estimation accuracy of the Oracle Optimizer in a 11.2.0.1 Oracle Database. Tests highlight the increase in estimation accuracy on the optimizer and impact on execution plan selection. Tests conducted against a numeric column in a heap table and execution plan results and statistics captured to indicate impact on the optimizers execution plan selection of the OHU histograms. IMPORTANT NOTE: This utility is not a substitute for oracle's dbms_stats which calculates highly valuable statistics for oracle objects. It is an add on utility that can be used on columns with skewed distribution. Please see demonstration one for overview of architecture
