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 Data Guard Tutorial - Open the Standby Read Only (Part 2 of 4)
 
16:49
This tutorial provides a quick review of what Data Guard is, and then goes on to show how you can extract value from Data Guard in every-day usage: how you can use it to enhance performance, and to reduce (yes, reduce!) your need for Oracle licences. Opening the standby database read-only. This has in fact been possible since the automation of redo transport and redo apply when it was first introduced in release 8i. Redo is received on the standby database but is not applied. So the redo is written to the RFS, slave to standby logs, archive to standby logs into archive logs but there's no apply done. So recoverability is not compromised. There's still no danger being lots of data. You're still receiving. The thing is open read-only. What does that mean? It means you can run queries against it. You can offload all your heavyweight queries from the primary to the standby. When I say all of them, even queries that require vast massive temporary space, those horrendous queries, those doing hash joins between multi gigabyte tables, they'll be generating many gigabytes of temporary data. You can write temporary data. Provided that you're using proper temporary tablespaces which you're certain you should be, you can run any query no matter how big, no matter how much temporary data it needs. You can also write audit data and this is important because with version 11, there's quite a lot of auditing enabled by default. By default, that auditing goes to the database, writing database tables. And you can't write to a database table in a read-only database. That we can configure for automatic switching and direct the audit records to the operating system or the trail instead. The queries you run, why is this such a good facility? First, you're taking stress off the primary. I'm sure that we're all DBAs here and we all know how difficult it is to tune your database or a concurrent workload that includes both high volume DML and includes heavyweight queries. Basically, you can't tune that way at all. Offloading the queries to the physical standby will reduce a lot of stress from the primary. So your DML should run significantly better and you can even do a certain amount of tuning on the standby to tune for optimal query performance. The most obvious tuning one would do, would be the memory parameters. No one could for example give the primary a massive PGA aggregate target and the much smaller SGA target or use indeed automatic memory management, perhaps cell tuning. One can adjust many parameters to do with tuning the optimizer to drive the optimizer to a certain execution plan, to exploit the environments. All that can be done on an open read-only database. How does one do it? It really couldn't be simpler. If we look at my physical standby here, this thing database role, physical standby - and if we select the open mode from v$ database, we find this in mount mode. How do we actually open at read-only? First off, we have to stop the recovery process because remember redo is received but no applied. You have to cancel the recovery. So "alter database recover managed standby database cancel." That will give us a read consistent version of the database. The command is intelligent enough to know that there might be incomplete transactions. Long-run transactions could've been partially received. We will end up with a read consistent version. To cancel it, all we do is alter database open read-only. It is that simple.

Why Isn't My Query Using an Index?
 
47:01
“Why isn’t my query using an index?” is a common question people have when tuning SQL. This session explores the factors that influence the optimizer’s decision to answer this question. It does so by comparing fetching rows from a database table to finding all the red M&Ms a packet, and contrasts using an index range scan and a full table scan. It also introduces the concepts of blocks and the clustering factor. The session offers a discussion of how these affect the optimizer's calculations, and includes a demo of how these concepts work in practice using real SQL queries. This session is intended for developers who want to learn the basics of how the optimizer chooses between an index range or full table scan. Speaker: Chris Saxon

Table Compression Enhancement in Oracle Database 11g R2
 
05:00
Table Compression: Overview Oracle Database supports three methods of table compression: 1.Basic table compression 2.OLTP table compression Oracle Corporation recommends to compress all data to reduce storage costs. The Oracle database can use table compression to eliminate duplicate values in a data block. For tables with highly redundant data, compression saves disk space and reduces memory use in the database buffer cache. Table compression is transparent to database applications. The table_compression clause is valid only for heap-organized tables. The COMPRESS keyword enables table compression. The NOCOMPRESS keyword disables table compression. NOCOMPRESS is the default. With basic compression, the Oracle database compresses data at the time of performing bulk load using operations such as direct loads or CREATE TABLE AS SELECT. With COMPRESS FOR OLTP, the Oracle database compresses data during all DML operations on the table.
