This issue is very common and commonly faced by DBA, developers and server management team on production server i.e. SQL server leads into 100% CPU usage and also start consuming all available memory. Now most of the time you have seen technical people restarting sql services, or killing long running processes and even restarting complete server, and they can avoid this situation. Before starting any thing I would like to discuss a common myth people have that this is happening because of long running queries only. Which is not all ways true, some times: Longer running query can be problem Query having maximum worker time are also problem Query execution count can also cause problem For script check below link: http://www.techsapphire.in/index/sql_server_100_cpu_usage_fix/0-166

In this webinar Oracle Ace, Craig Shallahamer, will demonstrate how to do an Oracle time based analysis including integrating the OS situation into our analysis and finding the true “top” SQL. This journey includes a trip into Oracle’s library cache, memory access control and some interesting ways to improve SQL statement performance. Overall performance sucks as far as the users are concerned. After months of meetings management finally wants you to get involved. You run an AWR report for one of the most intense hours and notice the top “event” is "DB CPU" followed by "cursor: pin S wait on X”. This is where the webinar begins!

Detailing Oracle CPU Consumption: The Missing Link helps Oracle Database Administrators answer this question, "What's Oracle doing with all that CPU?" For details go to http://www.orapub.com/video-seminar-detailing-cpu-consumption Here's the problem: While Oracle has the world's most advanced database wait time instrumentation, Oracle does NOT instrument CPU consumption. This presents the Oracle DBA with a tuning handicap because CPU consumption can be a significant component of database time. The unintentional result can be solutions with a wait time bias and solution guessing. In this session you will learn how to determine where Oracle is consuming CPU down to the Oracle kernel code function level and how this relates to the broader performance situation. Now you will be able to more effectively develop solutions to reduce both CPU consumption and wait time. Important: The solution created to solve the CPU detail limitation is Linux based. While I'm confident there are very similar solutions in other operating systems, I do not explore this. What You Will Learn - How to answer the question, "Is that process doing anything or stuck?" - How to answer the question, "So what is Oracle doing with all that CPU?" - How to overcome the problem of understanding limitation when there is little wait time but lots of CPU time. - Finding the Oracle kernel function when there could be a possible bug. - Helping you understand what Oracle is doing, "under the hood." Modules - The problem and what to do about it - My journey to find a solution - Creating the solution based on the Linux "perf" tools - Examples of how to use the tool in production situations For information on how you can watch the whole seminar or for more great eduction from OraPub, go to www.orapub.com

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

Presented by Karen Morton Tues 8th May 2012 Summary SQL is utilized to return data via our applications to service user requests. Whether it's a single customer lookup or a huge month end summary report, the SQL we write must gather the correct data and return it to the user. Ensuring that the SQL you write can do this in a timely and efficient manner, both now and in the future, requires that you measure and evaluate what resources your query must use. In this webinar, we'll cover several methods for how to collect data that show you precisely how your SQL consumes resources: Using AUTOTRACE Using DBMS_XPLAN.DISPLAY_CURSOR Using Report SQL Monitor Using ASH (Active Session History) and AWR (Automatic Workload Repository) data You'll learn how to utilize the data to understand the work your SQL is doing and the resources it consumes; identify currently evident performance issues as well as areas that could be problematic in the future; and modify your SQL to use less resources more efficiently while still returning the desired results. A live Q+A session with Karen Morton follows the presentation. For our complete archive, and to sign up for upcoming webinars please go to http://www.red-gate.com/oracle-webinars

Mark Champion, Product Marketing Manager at Redgate, talks you through the major new features in SQL Monitor 6, including: 00:33 New diagnostic interface 03:10 Query plans To find out more about SQL Monitor, visit https://www.red-gate.com/sql-monitor Or download it now https://www.red-gate.com/dynamic/products/dba/sql-monitor/download ----- Transcript ----- Hi I’m Mark Champion, one of the team behind SQL Monitor. We have recently released version 6 of our SQL Server monitoring and alerting tool, SQL Monitor, and I want to show you what’s new, what’s great and how SQL Monitor can make your job easier. In version six we have make it quicker and simpler to diagnose the cause of problems affecting a server. The main changes you will see are centred on the server/instance overview, which we get to by clicking here. In previous versions the information was displayed across a variety of screens, and it could be fiddly to jump between them to get the information you needed. In version six we’ve brought all that information together into this one server overview. Starting at the top of the page there’s an overview graph showing four key metrics for this server, the CPU and Memory usage, Disk I/O, and Waits. These can all be turned on and off like this. We can also baseline any of these, based on the previous 7 periods. By default this graph shows the past 24 hours, but you can look at longer or shorter periods like “The last 6 hours” or “the Last 2 days”, and of course, you can rewind time as in previous versions. Another thing you’ll notice is that underneath the graph there are small circles. These indicate alerts that happened over your select period and they are colour-coded according to severity. If I hover over the circle I get a brief description and if I click it, I can see the details for that alert in this right-hand-side panel. I can also now directly clear the alert from here, or jump straight to that alert’s settings. This makes it easier to clear and tune alerts as they arrive. Having the alert information on the same page as the metrics gives you additional context so you have a better understanding of exactly what was going on with your server. You’ll see on the overview graph, there’s a highlighted window in white. This is the “Focus Window”. We can move it around or resize it using the handles. Everything below that graph now updates to look at just that narrowed time window that we have selected. For example, I might want to take a look at this spike in CPU usage from this morning. The 4 graphs below break out those metrics further, and let you see some finer detail which isn’t visible on the main graph above. All the other metrics you will see below are also tied to the period selected in the Focus Window. So first we have Top Queries and Top Waits ( I’ll come back to the top queries section in a moment) , but scrolling down or using the navigation on the left here, we can see various other metrics you’d expect from the previous version, including general metrics, processes, the error log and databases. We can click any of the databases here and see full details for that database appear. Jumping back up to the top to the top queries list, we can see another major new enhancement. If we choose to look at this most expensive query, we can see a new query plan button. We automatically pick out expensive operations which you can jump straight to by clicking here. We also automatically pick out certain warnings for you. Here for example, we show that there was an operation with no join predicate, which is the reason this query runs slowly, and can be used to understand how the query could be rewritten better.
