, but it can be opened in read-write mode. At this stage, the master database and the logical standby database are different. The physical (and snapshot) standby database synchronizes with the master database by applying redo logs. In contrast, the logical standby database synchronizes data by executing the same SQL statements as the master database. This mechanism is generally called SQL apply. SQL apply uses the log miner feature to extract SQL stat

depends on the read-write mix of the databaseWorkload. Because queries do not need to log any flashback data, the more write-intensiveWorkload, the higher the overhead of turning on flashback database.Note: flashback database logs are not archived. Flash back buffer, flashback buffer (in share pool ),Flashback logs are special. Flashback databases rely on flashback logs. logminer mines archived logs to ensure consistency. Truncate table EMP; how to restore it?[First flash back to a time point,

Automatically find the best model from these models to interpret and apply the model according to the business.Common data Mining modeling tools(1) R.R is a language environment designed for statistical computation and graphical display, and is an implementation of the S language developed by Rick Becker, John Chambers and Allan Wilks of Bell Labs.(2) Python.Python is an easy-to-learn and powerful programming language with efficient advanced data stru

BlackBerry's launch of Android phones in the year is largely a certainty, and recently, BlackBerry has publicly announced that it has established a partnership with Google to customize a more secure Android version number for business users.2) Google acquired Android 10 annive

In the process of using Kali, sometimes found very card, the use of memory will suddenly rise, originally normally, memory occupies about 30%, and then under the Gnome-terminal, run the top command a look, there are a few to tracker start process actually occupy nearly 100% Memory, even the cache is accounted for 99%, Pit Daddy Ah.So, naturally think of the software to unload, however, the fact is not so simple. If you uninstall tracker software, you will uninstall many important software, such

(3) Output hint informationFormat: ECHO information contentThese are the three common uses of the echo command, which are familiar and available, but you should also know the following tips as a DOS command miner: (4) Turn off the DOS command promptType echo off at the DOS prompt to turn off the display of the DOS prompt so that the screen leaves only the cursor until you type echo on and the prompt will appear again. (5) Output blank line, which

Java that allows rapid development of machine learning and statistical applications. The core focus of the framework is a large number of machine learning algorithms and statistical testing that can handle medium-sized datasets.9. Deeplearning4j is the first commercially-available, open-source, distributed in-depth learning library written in Java and Scala. It is designed to be used in a business environment, not as a research tool.Mahout is a machine learning framework with built-in algorithm

The exclamation is the blood that the warrior drops on the road of climbing, but also the tears that flow when the coward is disappointed. Smooth sailing, not equal to the driving is a flat route. In the vast desert, the only step forward is the symbol of hope. GRF, who climbed the summit of the Mountain, was born of the Gung Cen and the will of "not to the Great Wal

When it comes to data mining, our first reaction is the story of beer and urine that we've heard before, which is a typical association rule in data mining. The main difference between shopping basket analysis and traditional linear regression is that the correlation analysis is aimed at discrete data;Common Association Rules:Association rules: Milk = egg "Support degree =2%, =60% confidence"Support: 2% of all transactions in the analysis at the same time purchased milk and eggs, you need to set

parameters: When the function is defined, the parameter is already assigned a value, the call stage can be used without passing the value (the value is basically the same as the default parameters, the call stage can ignore the non-pass value.) such as the sex of a miner, the birthplace of a student in a rural primary school, etc.). Factors to note: One: must be placed behind the position parameter; Two: default parameters are usually defined as immu

WiktoCan say that this is a webserver evaluation tool, it can check the vulnerability in the webserver, and provide the same as Nikto, but add a lot of interesting features, such as back-end miner and tight Google integration. It is written for the ms.net en

The echo command is a child command of a DOS batch command familiar to you, but some of its features and usage maybe you don't know all about it, you see: 1. Whether to display the command line itself at execution time as a control batch command Format: ECHO [on| OFF] If you want to turn off the display of the ECHO off command line itself, you need to precede the command line with "@". 2. Displays the current ECHO setting state Format: ECHO 3. Output hint information Format: Echo Information con

Development is divided into two sections, part A:LSP (Live Sequence Protocol), parts b:distributed Bitcoin Miner Document Location: HTTPS://GITHUB.COM/MODIZIRI/P1 Body: "First of all, the low-level network protocols, called low-level because this IP can only provide unreliable data delivery services, that is, this simple data transfer can easily lead to delay, packet loss and duplication." Also, there is the maximum byte limit. Fortunately, however, t

Solitary blocks (orphan block) In the Bitcoin protocol, the longest chain is considered absolutely correct. If a block is not part of the longest chain, it is called a "solitary block." An isolated block is a block, it is also legal, but it is found later, or the network transmission is slightly slower, but not as part of the longest chain. In Bitcoin, the lone block has no meaning and will then be discarded, discovering that the lone miner is not re

"ECHO off" command line itself, you need to precede the command line with "@". 2. Displays the current ECHO settings status format: Echo 3. Output hint Information format: Echo message content The above are three common uses of the echo command and are familiar and available, but as a DOS command miner you should also know the following tips: 4. Turn off the DOS command prompt by typing echo off at a DOS prompt, you can turn off the display of the DO

owner of the currency). When a miner prepares to dig a new block, he puts the deal in a block and starts digging. When a new block is dug out, all other nodes in the network receive a message telling others that the block has been dug up and added to the block chain. When a block is added to the block chain, the transaction is completed and its output can be referenced in the new transaction. Elliptic Curve Encryption As mentioned previously, public

Deeplearning4j is the first commercial-level, open source, distributed in-depth learning library written using Java and Scala. The purpose of the design is to be used in a business environment, rather than as a research tool. Mahout is a built-in algorithm for machine learning framework. Mahout-samsara helps people create

sufficient for 200 to 400 concurrent connections, if the connection is increased, Can increase CPU and memory. MTS has some of the following drawbacks: 1. The code path for a shared server is longer than a dedicated server, so it is inherently slower than a dedicated server.2. There is the possibility of an artificial deadlock, because it is serial, all shared servers are bound together (a process), as long as one connection is blocked, all users are blocked and most likely to deadlock.3. There

, so that the new area block to add to the block chain. The amount of calculation is too great to get up. This process is called mining (mining), because the difficulty of calculating a valid Hash is like finding a grain of sand in the world of sand. The machine that calculates the Hash is called the mine machine, the person who operates the mine machine is called the miner. vi.. Difficulty coefficient Read here, you may have a doubt, people say that

generate the next block only after the newest block. So you have no choice but to sync at once when you hear the signal. Therefore, the block chain of the inventor Ching (this is a pseudonym, the real identity is unknown) deliberately let add new area block, become very difficult. His design is that on average every 10 minutes, the whole network can generate a new block, an hour is six. This output speed is not achieved through the command, but deliberately set a huge amount of calculation. In
