OTM Performance tuning by Dominic Long and Daniele Patetta (Oracle Consulting)
 
25:29
Presentation by Dominic Long and Daniele Patetta (Oracle Consulting) during the OTM User Conference in Amsterdam on 21 March 2019. The performance tuning method used by Oracle Consulting EMEA consists in an iterative approach from both a technical and functional point of view: 1. Analyze the machine performance: Threads utilization and Cache hits, 2. Max out the threads utilizations on the topics that were used the most, 3. Analyze the full functional configuration, 4. Break down the processes in several sub-processes and 5. Analyze processes one by one trying: Optimization of the process itself, Substituting the functionality with a less time consuming one Once these five steps are accomplished, if the desired level of performance is not reached yet, start again from step one. This exercise needs to be performed keeping an eye on solution quality (especially regarding planning). Dominic Long is a Technical Consultant with many years of OTM experience during which has helped a large number of customers with performance and infrastructure in addition to carrying out implementations. Daniele Patetta is a Functional Consultant, he joined Oracle Consulting in 2016 and since then have been involved on several OTM Implementation. These implementations were mostly focused on Retail and Food Processing Sector. Also he has been involved in several presales activities. OTM functionalities implemented: Core OTM, Operational Planning, Fleet Management, Sourcing, Transportation Intelligence, Freight Settlement. He holds an Industrial Production Engineering Degree from Politecnico di Torino and an Executive Advanced Master in Strategy & Management of International Business (ongoing) from ESSEC Business School.

Just a quick video showing what happens when you give an offering (obtained through Petra's weekly bounty) to the Oracle, aka, The Queen. Got some really nice stuff and now I have 3 Reverie pieces of armour allowing me to melt even more than I was. Also hit 515, hopefully that's close to raid ready. Also got some special bounties which reward me with the Dreaming City exclusive perk, that's nice. Aside from that I hope you enjoy this short but eventful video. Not sure if I'll do one on the Ascendant Challenge as I already beat it, but might do it anyway.

Remove Junk Files to Cleanup Your Windows 10 Computer
 
05:22
Remove Junk Files to Cleanup Your Windows 10 Computer Firstly, let’s delete the Windows update data. To do that, open C drive, then Windows, then Software Distribution and here choose Download. We have around 1 gig of Windows update data and we don’t need it. If the system needs any file, it will be downloaded again. So no issues. Let me delete everything here in this downloads folder to remove junk files to cleanup the Windows 10 computer. So now the second one. Let’s delete the temporary & prefetch files. To do that, open Run by right-clicking on the #Windows icon and here choose ‘Run’. In here type %temp% and choose ok. Now you will see all the temporary files and delete them all by saving any of the work that you are currently doing with any of the applications. Again open Run by right-clicking on the Windows icon and now just type temp. This is another location where the temp files are stored. Just, delete them all to clean up the temp location. Now we’re going to delete the prefetch files. To do that, open Run dialogue box by typing Windows + R keys together and type prefetch. Select all the files and folders here then proceed to delete them. This is how you remove junk files to clean up your #Windows10 computer. Now, the third one. If you have any issues with the Windows store then just do this thing without changing account settings or deleting installed apps. By opening the Run dialogue box, type wsreset and hit ok. Now you will see the command prompt with a blank screen. You need to wait for a few seconds to complete the reset process. Once done, you will get the Windows store on the console. The fourth one is clearing the browsing history of #Microsoft edge and chrome as I have them. You can try clearing the browsing history of all the browsers that you have. So, now going with Edge browser, Open it and choose these three dots right here and choose settings. Now at the center, click on ‘Choose what to clear’ under ‘clear browsing data’. Tick what you want to delete and choose ‘clear’. Alternatively, you can opt to ‘Always clear this when I close the browser’ option if you wish to clear browsing data regularly to remove junk files to cleanup your windows 10 computer. If you are using #Chrome browser, do these steps to delete the browsing history. Open chrome and choose these three dots to expand the available options. From the menu, choose ‘More Tools’ then ‘Clear browsing data’. You will get a window with basic options. Navigate to the ‘Advanced’ tab and choose the time range, what things you would like to clear etc and click on ‘clear data’. That’s it. The fifth one is to clear the DNS cache. If you have any internet connectivity issues you can run this command to flush the DNS cache. To do that, search for cmd and right click on it to run the command prompt as an administrator. Now here type the following command. ipconfig/flushdns and it will instantly clear the DNS cache for you. The sixth one is to clean up the disk. To do this search for Disk cleanup and open it. Choose the disk you would like to clean up and here I’m choosing the C drive. Now choose the files that you would like to clean up and select ok. It will then clean up the junk files that are in C drive. The seventh one is to free up the space using a restore point. To do that, search for restore point and then open it. Once you have the system restore point window, choose the C drive and choose ‘configure’ to look for the space that was occupied at restore point. Now I have around 2 gigs here and you just need to delete it by choosing delete and press ok. Now create a new restore point and name it as you like. I’m here naming it as restore and it will take less space now. This is how you can remove cache or junk files to cleanup your Windows 10 computer manually without using any software.

Oracle VSM Buffer Efficiency
 
04:10
For more information, visit: https://www.intellimagic.com/z-os-products/intellimagic-vision-for-z-os This video was originally recorded in our webinar: IntelliMagic Vision for z/OS Tape Version 8.8. Most Oracle VSM’s have a buffer or cache that is used to temporarily hold a tape volume’s data. This video shows how IntelliMagic Vision can be used to determine how that buffer capacity is being used and what percent of the tape reads are buffer hits which give better mount performance. These are broken down by VSM Management Classes since you generally expect different workload characteristics from different management classes.

When Dynamic Becomes Static: The Next Step in Web Caching Techniques: Wim Godden @nginxconf 2014
 
30:12
When your site gets swamped by a huge amount of visitors, tools like Varnish ESI can improve scalability for static sites, but when user-specific content is needed, a hit to the backend webserver is still needed, causing scalability issues. We'll look at a new Nginx module which implements a fast and scalable solution to this problem, changing the way developers think about designing sites with user-specific content and changing the way data is (pre)processed for dynamic websites. Wim Godden has been working with open source technologies since 1997 and has been involved in open source projects such as OpenX and PHPCompatibility. Next to web development, he's worked with a wide range of technologies (from database clusters to Internet backbone design) and focuses a lot of his time on high-scalability projects and on coaching/training web engineers.

Getting Better Query Plans by Improving SQL’s Estimates by Brent Ozar
 
50:44
You’ve been writing T-SQL queries for a few years now, and when you have performance issues, you’ve been updating stats and using OPTION (RECOMPILE). It’s served you well, but every now and then, you hit a problem you can’t solve. Your data’s been growing larger, your queries are taking longer to run, and you’re starting to wonder: how can I start getting better query plans? The secret is often comparing the query plan’s estimated number of rows to actual number of rows. If they’re different, it’s up to you – not the SQL Server engine – to figure out why the guesses are wrong. To improve ’em, you can change your T-SQL, the way the data’s structured and stored, or how SQL Server thinks about the data. This session won’t fix every query – but it’ll give you a starting point to understand what you’re looking at, and where to go next as you learn about the Cardinality Estimator.

Oracle Exadata Smart Scan - Limitations and Best Practices
 
03:21
Smart Scan is a wonderful capability, but you don't always get it. It's impossible for many execution plans, and this is a major restriction. If you think about what a Smart Scan actually does, it delivers individual columns, individual rows back to the instance. Now, a buffer cache can accept only blocks. Therefore, Smart Scan cannot possibly put those columns of rows into the buffer cache. It's simply not formatted appropriately. So, a Smart Scan has to return values directly into the session's PGA or, to put it another way, the only access method that can use Smart Scan is direct read. Well, what access methods can use direct read? There are only two, which are table full scan and index fast full scan. Any other access method, typically index range scan, table access by row ID, cannot use a Smart Scan. The second major issue, there are strict limitations of the type of objects that can be accessed through Smart Scan. It really is only heap tables. You can't use indexes. You can't use clusters. You can't use IOTs. Heap tables only. Perhaps hardest to track down and giving sometimes very erratic results is that Smart Scan can be interrupted by various conditions. You've met all the requirements for Smart Scan, directory and so on, got the right execution plan. The Smart Scan starts and then hits something that causes a problem. Issues that we know cause problems are, for instance, read consistency, also delayed block cleanout, change rows. Any of those issues and a few others mean that the storage tier will have to interrupt its Smart Scan, deliver complete blocks into that buffer cache, let your session then do what is necessary to the block, and only then can the Smart Scan proceed. Now, in order to maximize the use of Smart Scan, there may be quite a lot of work. Very often, you'll have to adjust your index structures. Making them invisible is a nice technique there. There are many, many, many parameters that can influence the likelihood of achieving a Smart Scan, and almost inevitably you're going to be rewriting a lot of hint SQL and putting hints in it to get the correct execution plans that can enable a Smart Scan to occur. This is all because of one fundamental problem; the optimizer is not in any way aware of the Exadata. The optimizer develops an execution plan in exactly the way it would without the Exadata storage. The use of Smart Scan, the awareness of Exadata comes at the next level down. The optimizer develops the plan through a normal pass and then passes it through to the SQL execution engine, and it's the SQL execution engine that determines, on a case-by-case basis, whether to use the Smart Scan. This means that you might develop a plan and execute the statement 50 times. Forty-nine times, you get a Smart Scan. The 50th time, for whatever reason, the SQL execution engine decides not to. This can result in somewhat erratic performance.

Rihanna Hit Back At The Fan Who Mocking LeBron James : "B*tch, the King is still the King"
 
00:12
After a weeklong layoff, the NBA playoffs resumed Thursday at Oracle Arena with Kevin Durant reminding everyone why Golden State made him such a priority in free agency last offseason. The Warriors routed the Cleveland Cavaliers 113-91 in Game 1 of the best-of-seven NBA Finals behind 38 points from Durant in the third straight championship matchup between these two teams. “We could be a lot better than we were tonight,” Durant said. “I’m only as good as my teammates. And Steph [Curry] and Klay [Thompson] and Draymond [Green] and Zaza [Pachulia] and the rest of the guys, we just complement each other, try to complement each other and try to make the game easier for each other.” It was an impressive start to “The Trilogy” as the clubs combined for 65 first-quarter points before a sellout crowd of 19,596, putting to rest any concerns about rust from the long break between the conference finals and the NBA’s main event. Rihanna, a noted LeBron James fan, didn’t let the Warriors’ domination in Game 1 of the NBA Finals spoil her fun at Oracle Arena. In fact, amidst a Cavaliers annihilation, she bowed to LeBron, and then came back at the Golden State fans behind her and dabbed with authority. so watch Rihanna Hit Back At The Fan Who Mocking LeBron James : "B*tch, the King is still the King."

Solving Performance & Capacity Issues
 
06:18
Reliant Technology http://www.reliant-technology.com 1.877.227.0828 First things that I would look at if I was having, let's say, performance problems on, in an environment, is I would go and check the overall health of the storage array. How do you do that? You go and you look at performance data generated by the SPs. A few things that I would look at SP utilization. You want to make sure that your storage processors, or each storage processors is not being more than 50% utilized. Well, why only 50%? A reason I say that is because they're meant to be redundant SPs, so, if one SP were to fail, you want to ensure that the other SP has enough capacity or CPU cycles on it to be able to take on the load from the other SP in the event of failure. Another thing that you would consider would be cache utilization. Take a look at the dirty pages on the storage processors and take a look and see if it's being over utilized. In a storage array, especially on VNXs, you can run into a situation that's called force flushing. Basically what this means is that the SP cache is at 100%. When this happens, the storage array basically tells all of your systems that I'm not going to take anymore IOs until I can dump some of this cache down to disk. When you've got an environment, let's say, that's high IO utilization, but it's on the wrong type of disks. For example, I've got an Oracle database that is writing data files to SATA disk. In this situation, your SATA disk is not able to keep up with the transactions coming from the database. Roughly between 70 to 85 IOPS. If you've got a RAID group that, let's say, of eight disks, after your rate calculations and everything over, you only have a specific subset of IOPS that you can actually use. If your database is an OLTP type database, where it's constantly hammering the disks, then the RAID group will not be able to keep up with the amount of writes coming in from the host. The storage array will then take the majority of those writes and it'll write it into cache. That way, the system is allowed to continue working and the array is saying I'm going to load this into cache and I'm going to dump it into disk. I get three cycles. If you run into an environment like this, what can happen is your cache will quickly fill up. Once the cache has filled up, your array will hit what is called forced flushing. During this time, the storage processor will no longer accept any more writes into cache until it can dump those dirty pages down into the disks. You'll have situations where, basically, the SP cache is unable to keep up with the amount of writes coming in from the host and write them to the disk in a timely fashion. This can be very detrimental to the performance on your system and it can cause outages. That would be a thing to look at. Is my cache being heavily utilized? If so, why? Which environment is basically writing to the wrong type of disks? Once you identify that environment, you can make strides to moving it to faster spindles. In that example, if I were to move those data files or those LUNs for that Oracle database from a SATA tier to a fibre channel tier, that will reduce the cache hit rate on my storage processor and it'll increase overall performance on the system. You can move it to a different type of disk, like in our previous example, or you can add additional spindles into the pool that that system resides in. Back into the previous example, let's say that environment is on fibre channel disks, but the amount of fibre channel disks that I have in that pool is not sufficient to give the amount of IOPS that I need. So, you can add additional disks, which will give you additional spindles and it'll distribute that throughput across the additional spindles and it'll give you the performance that you need. Another option you can do, which is becoming fairly popular these days, you add an EFD tier to your storage array. What is EFD? They're solid state disks that act as another layer of cache for your system. VNXs have what's called FAST cache and you can add, I think, up to 5-10 disks into this FAST cache tier and it basically acts as another layer to be able to handle any type of burst IO coming from your system. Let's say your sustained IO is something that your SATA tier can handle or your SAS tier can handle. But every now and then, you'll have an event where you have some burst IOPS and you see it. You see some peaks in your performance log. Well, having that EFD tier there will give the array that wiggle room that it needs to be able to handle that IO event to where you're not having an array wide performance issue.

OWASP AppSecUSA 2012: Unbreakable Oracle ERPs? Attacks on Siebel & JD Edwards
 
40:23
Speakers: Juan Perez-Etchegoyen and Jordan Santarsieri Siebel and JDE platforms are a core part of our global business-critical infrastructure. Our credit card numbers, bills, personal information and consuming habits; top-tier companies' business processes and their most confidential information. It's all in there. Despite their criticality, there is still today very scarce public information on how attackers may try to break into these systems and what we can do to stop them, placing the bad guys in a very powerful position. The Auditing and InfoSec industries have been traditionally focused only on enforcing segregation of duties controls, and that's not enough anymore. Join us in this new presentation to understand, through several live demos, how intruders can remotely execute code, steal user passwords and manipulate proprietary technologies to perform espionage, sabotage and fraud attacks, without having a valid user in the systems. Furthermore, you will see how these attacks may be performed over the Internet. Learn how to mitigate these risks, starting by learning how to assess them in your company using the new version of Bizploit, the opensource ERP Penetration Testing framework, to be released after the talk.

Fusion : Design Tradeoffs in Coherent Cache Hierarchies for Accelerators (ISCA42)
 
21:49
Chip designers have shown increasing interest in integrating specialized fixed-function coprocessors into multicore designs to improve energy efficiency. Recent work in academia and industry has sought to enable more fine-grain offloading at the granularity of functions and loops. The sequential program now needs to migrate across the chip utilizing the appropriate accelerator for each program region. As the execution migrates, it has become increasingly challenging to retain the temporal and spatial locality of the original program as well as manage the data sharing. We show that with the increasing energy cost of wires and caches relative to compute operations, it is imperative to optimize data movement to retain the energy benefits of accelerators. We develop FUSION, a lightweight coherent cache hierarchy for accelerators and study the tradeoffs compared to a scratchpad based architecture. We find that coherency, both between the accelerators and with the CPU, can help minimize data movement and save energy. FUSION leverages temporal coherence to optimize data movement within the accelerator tile. The accelerator tile includes small per-accelerator L0 caches to minimize hit energy and a per-tile shared cache to improve localized-sharing between accelerators and minimize data exchanges with the host LLC. We find that overall FUSION improves performance by 4.3× compared to an oracle DMA that pushes data into the scratchpad. In workloads with inter-accelerator sharing we save up to 10x the dynamic energy of the cache hierarchy by minimizing the host-accelerator data ping-ponging.

This Hacker has ninja skills but I rip his mask off! ▶ Vy Confronts Lie Detector Guy - https://goo.gl/7EfqG1 ▶ Spy on Project Zorgo to help us https://youtu.be/6r9PnCmQTIA ▶ Play CHAD's Video Game Free https://qkq5h.app.goo.gl/chad After Vy Qwaint and I, Chad Wild Clay were searching for and found a NINJA Gadgets MYSTERY BOX to Battle PROJECT ZORGO (Gadgets Unboxing Haul Top Secret Clues of Hacker) we chopped and searched for clues like a fruit ninja. Inside were puzzles from the hackers we think. Or maybe it was the mysterious lie detector man? We also discovered a SPY GADGETS MYSTERY BOX Challenge Unboxing Haul to Defeat PROJECT ZORGO! (Found Top Secret Clues) inside the eBay mystery box. It was like an $10000 unboxing haul challenge. The treasures inside were a little creepy, with weird secret hidden messages written on them? Was this box haunted by a ghost at 3am? We searched our hidden cameras for evidence regarding Project Zorgo, who has been pranking YouTubers like Stephen Sharer, Carter Sharer and Lizzy Sharer. It looked like the mysterious unknown lie detector man was trapped by someone. He need to help him so he can escape! He left a tracking device and we used our gadgets to search for hidden underground passageways that may lead to his location. To our surprise, a Project Zorgo hacker member showed us ready to battle us with ninja stars. I wouldn't go down without a fight and chased him throughout the abandoned desert.
