Oracle Database Memory Serialization Control (latches & mutexes)
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

How an intense and diverse SQL statement workload can cause Oracle parsing problems
Make your library cache angry! This video is about how an intense and diverse SQL statement workload can cause Oracle parsing problems. There are many reasons for Oracle parsing related performance issues and many ways to identify them. So, I am narrowing the scope by focusing on one possible cause, that is, an intense and diverse SQL statement workload. I will use Oracle's wait interface to identify the root cause. Sound dry and boring? To make this a little more interesting and a whole lot more fun, I'm going to approach this from a non-traditional, almost backward perspective. After explaining some of the Oracle internals, I'm going to create a parsing intensive workload and then watch what happens... in real time. The educational impact is so powerful, I recorded a video This is video is part of Craig's blog post: http://blog.orapub.com/20170126/how-an-intense-and-diverse-sql-workload-causes-oracle-parsing-problems.html For more information go to www.orapub.com

Understanding and Optimizing Oracle Latches/Mutexes - Webinar
Understanding and Optimizing Oracle Latches/Mutexes. Oracle memory serialization control is core to Oracle database operations. One of the most fascinating topics in Oracle internals and performance optimization is memory serialization. We will look at the circumstances in which serialization is used, how it works, how to influence its operation, and how to diagnose problems. It's a complex situation; in order to get the upper hand on serialization control, this presentation will explore the lock (a little), the latch (a lot), and the mutex (a whole lot). Topics will include: performance diagnosis, how Oracle implements latches and mutexes, and related internal algorithms. Special attention will be given to the library cache mutex operations. This is a practical, yet deep internals presentation filled with amazing discoveries about how Oracle works. For more information go to www.orapub.com

Difference between blocking and deadlocking
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

Inside SQL Server Latches - Bob Ward
The SQL Server database engine uses latches for internal synchronization to critical operations. So why would you care about what a latch is? Well, if you have ever monitored a SQL Server closely, you know you can't escape latches. Come to this advanced session exploring the internals of how SQL Server uses the concept of latches for synchronization of key internal data structures. This talk is a very advanced "500" session that may include the use of advanced diagnostics such the Windows debugger and discussion of Windows APIs. I will assume the audience has a basic working knowledge of the SQL Server engine including an understanding of some of the more common SQL Server Engine DMVs such as sys.dm_exec_sessions, sys.dm_exec_requests and sys.dm_os_wait_stats.

Oracle X$TRACE, Wait Event Internals and Background Process Communication
In this session we will look into some internals of Oracle background process communication and also some special types of wait events that most people aren’t aware of. We will use some exotic tracing for internals research and fun and some of this stuff is actually useful in real life too! I’m not going to reveal everything upfront, as this is a secret internals hacking session after all ;-) We will use various techniques to research what the “reliable message” wait event is about and how reliable background process communication is orchestrated in Oracle. This is a hacking session, not formal structured training, so I’ll just do free form demos and talk (probably no slides, just hacking stuff on the command line).

Understanding And Resolving Oracle Free Buffer Wait Contention - Seminar Intro
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.

Fix: Empty Pmag gen 3 doesn't catch/lock bolt
AR platform is new to me, and I hope I don't upset anyone here because I am a noob when it comes to ARs. I recently assembled this Noveske rifle and bought 3 pmags M3 only to realize that most of the time the bolt wouldn't lock back on an empty mag. I then found a solution to the problem. Very simple to fix if you are having a similar problem. Of course not everyone has the same exact issue. When the bolt is closed, the bolt stop lever is prevented from raising by the bolt sitting above it. My brand new pmags had casting burrs on the inside of the body where the back of the follower, that also had a burr would snag. So, I assume that if you just emptied your mag, the follower is snagged on the burr, and the bolt stop is kept down by the bolt. The bolt comes back, the follower doesn't move up (because of the burrs) and doesn't raise the bolt stop - the bolt slams forward even though your mag is empty. Same thing happens when you insert an empty mag. The bolt stop was down, kept by the bolt above it. The bolt stop presses down on the follower as the empty mag is inserted. the follower catches the burr of the mag body, and doesn't come up. Bolt is pulled back, but the follower is not pushing up on the bolt stop, so the bolt slams forward when you release the charging handle. This is what I believe is happening and removing that pesky burr solves this issue, although i haven't fired this rifle yet and cannot know for sure. Let me know if I am completely wrong here.

How To Use The Oracle SQL Net Message To Your Advantage - Introduction
How To Use The SQL*Net Message From Client Event To Your Advantage - webinar introduction. Idle wait events are usually ignored in our performance analysis. It's because they diminish what we should be focus on... most of the time. We need master the "not most of the time" as well. So, in this webinar I'm going to focus on the idle wait event, SQL*Net message from client. I'll show you what this wait event is, why it's important and not important, and how to use it to our advantage in both a time-based analysis and an ASH based analysis. And of course, you'll be able to download and immediately use any tools that I use.

Intent - Locks in SQL Server - Part 6
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
