found that the value of statistical information estimates and the actual implementation of the value of the discovery Gap is large (misestimate), need to be optimized, will generate SPD. That is, if we see V$sql's is_reoptimizable field as Y, the statement needs to be tuned, and the SPD intervenes at the second execution, or similar to SQL execution. In 12.1, the only type of SPD is the dynamic sampling (dynamical sampling).
Oracle will get the SPD involved in the misestimate situation. From t
with the "media device" MTP mode, however, traditional data recovery software cannot directly recover data from the mobile phone storage space loaded in the MTP mode ,.
Therefore, it is necessary to study the data recovery methods suitable for Android mobile phones. This article mainly discusses the data recovery of the internal storage space of mobile phones. Traditional methods can be used to recover t
growth of the data volume, so the data volume of the Enterprise Data center will continue to increase, in its current in the million backbone, Gigabit access based on the network, we should also consider how integrated cabling to meet the needs of the next few years of network transmission, data center in the next few years will gradually realize the gigabit access, 40g/100g backbone of the network transmission mode.Tobacco Enterprise Data Center in the selection of media can refer to the follo

Step 1. Download and install the Kies software
If your computer is not installed Kies software we can download Baidu, the Kies software is a Samsung official provided a mobile phone assistant, if you install 360 assistants, or 91 of them will also give us mobile phone installation drive Oh, so we can choose the OH.
Step 2. Set up your phone
1. Use the original data cable to connect the mobile phone with the computer (mobile data cable connected to the computer USB interface can).2. The mobile
1. Install Samsung mobile Phone driver for computer We can use Kies software, this official has download can baidu search download
2. Open the USB debug mode of the mobile phone
1. Connect the mobile phone through the data cable to the computer USB interface, in the mobile phone standby page, slide the top curtain down.
2. Click "Connected for charging".
3. Select "Media Device (MTP)".
4. Read the prompts and click "
Recently, because I sometimes need to put files in my cell phone on my computer, my cell phone (Lumia630) needs to be connected to the computer and can be connected normally in Windows, however, it is not possible in Ubuntu, so I checked the information. The method is as follows: 1. add MTP File System: sudoadd-apt-repositoryppa: langdalepl/gvfs-mtpsudoapt-getupdate2. create udev rules (you can also use gedit

equipment maintenance operations are necessary during use and maintenance, therefore, its security is an issue that must be considered. Under normal circumstances, welding can produce a small connection loss, which is usually below 0.2dB, but the return loss is not easy to control. At the same time, during the optical fiber fusion process, there are many external factors that affect the welding quality, such as environmental conditions including temperature, wind power, dust, etc.), Operation p

Why do we see the rule? For any skeleton,Based on the position of the vertex in the Local Coordinate System of the skeleton, we can find a new position in the global coordinate system after the skeleton moves.The process is a (transformation in the local coordinate system) * (transformation to the parent Coordinate Sys
I just bought a Samsung S8500 one day ago, but cannot connect to the computer-installed Kies. I reported that the driver of the mtp usb device could not be installed. I found the solution on the Internet.
You must retrieve the TF card during connection. After pulling out the plug-in, connect to the PC kit and install the MTP driver. After the plug-in, everything will be normal. please be sure to install wi
transmission distance can reach 50 m at Gbps. parallel Optical Communication supports parallel transmission of multiple light sources, which can achieve long-distance transmission at a high bit rate ,. this is one reason for parallel optical interconnection.
Parallel Optical module and Band Optical Cable
Parallel Optical Interconnection is achieved through parallel optical modules and band optical cables. the parallel optical module is based on VCSEL arrays and PIN arrays, with a wavelength of
discuss the commonly used Optical Fiber Connection Technology:
1. Fusion mode: Optical Fiber fusion is currently a commonly used connection mode. In contrast, fusion is a method with a high success rate and connection quality. However, it should also be noted that, the welded joint is one of the main factors that are prone to damage or failure. Because equipment maintenance operations are necessary during use and maintenance, therefore, its security is an issue that must be considered. Under no
