Oracle SQL Performance Tuning for Developers: Understand Explain Plans
 
01:42
Understanding Explain Plans is an excerpt from Oracle SQL Performance Tuning for Developers: http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027 6+ Hours of Video Instruction The focus of Oracle SQL Performance Tuning for Developers LiveLessons is to illustrate coding techniques that ensure a consistent response time between instances and releases of the Oracle database. This course works closely with performance tuning of actual SQL statements. Description In this video training, Dan Hotka starts out with a complete overview of the Oracle architecture so students can get an understanding how their SQL and applications can take advantage of the computing environment. This course then goes in-depth on understanding and controlling the Explain Plan, which is how and in what order Oracle retrieves data. The discussion includes considerable detail, with SQL examples, on how the optimizers--both rule-based and cost-based, but mostly cost-based--make their decisions. Students will work with a variety of SQL statements, reviewing Explain Plans and making changes to make these SQL statements perform better. Lectures include index design, using hints and coding style to control the Explain Plans, and how to use useful tools such as index monitoring, SQL Trace, and the PL/SQL profiler. This LiveLessons course takes a close look at indexes: how Oracle selects them, why they are sometimes not used, and how to tell if indexes are being used. This course includes Oracle10g, Oracle11g, and Oracle12c SQL tuning topics. Skill Level Intermediate Learn How To Read and understand Explain Plan content Review an Explain Plan and tell quickly if this is a good plan Understand a good index column candidate from a not-so-good candidate Quickly tell the likelihood if your SQL will use an existing index Use coding and a variety of Hints (directives) that can produce better performing SQL Execute and interpret SQL trace output Who Should Take This Course Oracle programmers Oracle database administrators who need additional training on SQL tuning Course Requirements Working knowledge of the SQL query language http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027

Making Smart Scan for Exadata Work (Demonstration)
 
03:16
Making Smart Scan Work - Demo I'll go through a simple example of the kind of thing we need to think about when trying to achieve Smart Scan. Let me just enable tracing, run a simple query, select and * from *. Now, there's my query. The result set comes back, and how is it executed? An index full scan with the PK* index. The optimizer is intelligent enough to know that my query can be satisfied purely by reading the index and therefore it didn't have to go to the table at all. It looks very good. Well, it wasn't. Index full scans are an operation that cannot be offloaded. So, to execute that statement, every block of that index was delivered into the buffer cache of my own database instance, and the compute node then has to do the work of extracting those values. What can we do about it? One solution would be to hint the code. I select and demand an index fast full scan, and now we see the magic word "storage." An index fast full scan is offloadable, because an index fast full scan can do direct reads. An alternative approach? Well, you might not want to hint many, many thousands of lines of code. An alternative approach would be to do it through DDL. For example, take that index, make it invisible. Now run my statements without any hint at all, table access storage full, and that was offloaded. Having made the index invisible, Oracle has no option but a full-table scan, and a full-table scan is offloadable. Now, this means I have three options of this very simple example. I can let the optimizer get on with what it wants to do, and then I use an index that I'm doing block serving into the buffer cache. I can hint the code, index fast full scan. That's probably the best option for performance, but it's also the most work. In this intervening case, I make the index invisible so that it will still be used of course for enforcing the primary key constraints, but it will not be visible to the optimizer and therefore influence the optimizer towards using plans that can be offloaded the Smart Scan. Making the choice between this and influencing the optimizer in the correct direction is an extremely difficult job, and it is not always easy to determine what is going to be the best solution.

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).

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.

Oracle Tuning Tutorial - Long Full Table Scans Part 5 of 5
 
02:44
See all 5 tutorials, free, at SkillBuilders.com/OracleTuningFullTableScans. In summary, serial full table scans were always indirect before 11.2, parallel scans always direct before 11.2. These are the two critical parameters. That hidden parameter _serial_direct_read, remember, defaults to auto so your application may start behaving very differently as you upgrade from 11.2.01 or 11.2.02. Parallel_degree_policy, that defaults to manual. But again, it becomes an option when you go to 11.2 to enable the automatic facility which allows not only automatic tuning to the degree of parallelism but also enables the ability to make indirect reads when doing a full table scan.

Sparse Index - Unique Key: MongoDB

http://technotip.com/4225/sparse-index-mongodb/ All sparse indexes are unique index, but not all unique indexes are sparse! There are situations where we want to create unique index on key/field which is not present in all documents. Wherever the key is not present, it’s value will be treated as NULL. If more than 1 document has NULL value to the key we want to make as unique, then it violates unique key rule. In such situations we can make use of Sparse index and create unique key on only those documents which has the key in it. MongoDB Video Tutorial List: http://technotip.com/3778/mongodb-tutorial-list/

Plato's Apology Summary, Part 1 of 6: Defense vs the First Accusers
 
05:14
Summary of part 1 of Plato's Apology: Defense vs the first accusers (19a-24b) Music: Among the Clouds, by Darren Curtis Image: Plato. By Unknown - https://www.bildarchivaustria.at/Pages/ImageDetail.aspx?p_iBildID=8939684, Public Domain, https://commons.wikimedia.org/w/index.php?curid=74323586 Transcript: Hello, I’m Dr. Anadale. In this video I will go over the main content of what I am calling Part 1 of Plato’s Apology. In this part of the dialogue, Socrates introduces himself to the jury to begin his speech in his own defense, and he provides his defense against the early accusers, the first of the two sets of accusers he says he faces. In introducing himself, Socrates denies that he will deceive the jury by using fancy rhetoric. And this is one the charges against him. He claims that he will merely speak the truth, and he asks the jury to not be offended if he uses a crude form of speech, the kind of speech that he is accustomed to use in the marketplace, talking to anybody who will listen. Socrates then tells the jury that he faces two sets of accusers. The first set of accusers are the fathers and teachers of the jurymen. They have spent decades telling stories about how Socrates is a troublemaker, how he investigates natural phenomena, and makes weak argument defeat strong arguments. Notice that these are the occupations of the natural philosophers (who study the earth and stars) and the sophists (who make weak arguments win). Look for Socrates’ evidence against both charges: how he defends himself against the charge that he investigates the physical world, and the charge that he teaches unethical argument tactics. (Hint: the second answer involves being paid for teaching.) Socrates, in raising this issue of the early accusers, is indirectly pointing out the issue of bias on the part of the jurors. He is pointing out to them that all of them come with a set of quite strong beliefs that they have been instructed in by their teachers and fathers, about Socrates, who makes trouble, and who does all sorts of things. So he is appealing indirectly to their knowledge of his reputation in court, and how this might bias their judgment against him. Look for Socrates’ evidence that he gives against both of these charges. How does he defend himself against the charge that investigates the physical world, and how does he defend himself against the charge that he teaches unethical argument tactics? A hint for the second one is the question of payment, being paid for teaching. So look carefully for the evidence Socrates provides on both of those counts. Then Socrates offers the sort of example or comparison that many Athenians found offensive. He asks Callias where he would take his sons to be trained, if they were colts or calves. Here, Socrates is mocking the Sophists, and people who paid for their lessons. He suggests that they treat their students like livestock, not like free and intellectual human beings. In contrasting himself to the Sophists, Socrates also claims to possess no wisdom, or at least only human wisdom, he says, not the seemingly supernatural (godly) wisdom the sophists claim to have and sell. Then we have the story of the Oracle, in the last section of this part. Pay careful attention to this story and its details, as Socrates uses it to give the justification for his life of philosophizing, despite popular opposition. Here are some important points to note in the Oracle story: First, Socrates himself does not go to the Oracle; that would be hubris. His friend goes without his knowledge, and asks, ‘Is anyone is wiser than Socrates?’ Second, the Oracle’s response is NOT ‘Socrates is the wisest.’ Instead, she says, ‘No one is wiser.’ This is a significant difference. Socrates is not being singled out as being superior to all other Athenians, or all other Greeks, but the god does tell us that there is no one who is superior to Socrates. So think about that for a little bit. Third, Socrates’ reaction to the Oracle’s message is very important: he does not just accept her word for it uncritically, but he puts it to the test. And in testing it, he annoys his fellow citizens and he makes himself very unpopular. But finally Socrates comes to understand her meaning more deeply. Interpreting the answer ‘No one is wiser,’ turns out to be a lesson about the true value of human wisdom, says Socrates. Lastly, Socrates attracted a following among the young men of Athens, as he publicly questioned various authority figures in the city. This is one reason he was accused of being a sophist: his large following among the youth. Part 1 ends with Socrates turning to the later accusers, the ones who are present in court that day, prosecuting him. These are Anytus, Lycon, and Meletus. We’ll talk about Part 2 next. Goodbye.

🔥TWIN FLAME DAILY READING🔥DMs releasing burdens & offer love to the DF
 
28:38
Today's reading reveals that the DMs are releasing their burdens and making some changes in their physical life. They no longer want to be trapped in fear and having sleepless nights alone at home and so desire to be with their DFs. They want to communicate their truth to the DFs, end karmic cycles, and gain stability. They are currently working on their physical life, possibly finances and career. I do see that the DM is now wanting to have a heart to heart conversation with their DF, and this takes the DF by surprise where they are receptive to their DM love offer.

OpenMediaVault on DX4000 - Part 1 Hardware Setup
 
06:39
I had a Western Digital Sentinel DX4000 laying around and i want to use it. The DX4000 is actually running Windows Server 2008 R2. Since I could not connect Windows Server 2008 R2 to my Windows 10 PC, I tried installing OpenMediaVault. It was quite a challenge. I found the decisive hint for the installation on the website of Carlos Carbrera. http://cytekpr.com/index.php/2017/04/13/dx4000/ He had found out that there is a serial port on the motherboard for accessing the BIOS. It is the J23 connector on the motherboard. The order from left to right from the front is Power at 3.3V (not used), receive (RX), transmit (TX) and ground. To make a connection you have to use an usb to serial adapter and connect ground to ground, receive with transmit and transmit with receive. Under Linux, it is accessible via ttyS1,115200n8. This allows Debian to be easily installed over the serial port. OpenMediaVault can then run as a service on top of Debian OS.
