创建表空间:

create tablespace "FZXT_DATA_TEST"
logging
datafile 'D:\OracleEx\oradata\fzxt\fzxt.dbf' 
size 100m 
autoextend on 
next 1m extent management local;

创建用户并分配权限:
create user fzxt_test identified by "fzxt_test" default tablespace FZXT_DATA_TEST;
grant resource,connect to fzxt_test;
grant select any table to fzxt_test;
grant select any dictionary to fzxt_test;
grant create any trigger,create any view,create table to fzxt_test;
grant exp_full_database,imp_full_database,resource,create any sequence to fzxt_test;


导出数据:(实例)
exp userid=fzxt/fzxt@fzxt_13 file=./fzxt.dmp log=./dmp.log owner=fzxt


导导入数据库:(实例)
imp fzxt_test/fzxt_test fromuser=fzxt touser=fzxt_test statistics=none file=fzxt.dmp ignore=y log=./imp.log

fromuser就是把当前的dmp文件中的某一个用户下的数据取出。

touser就是把现在dmp文件中的数据导入到目标库的指定user下。

Slow Cellular Data Internet Speeds on iPhone: Fixes Slow Cellular Data Internet Speeds on iPhone: Fixes May 03, 2024 pm 09:01 PM

Facing lag, slow mobile data connection on iPhone? Typically, the strength of cellular internet on your phone depends on several factors such as region, cellular network type, roaming type, etc. There are some things you can do to get a faster, more reliable cellular Internet connection. Fix 1 – Force Restart iPhone Sometimes, force restarting your device just resets a lot of things, including the cellular connection. Step 1 – Just press the volume up key once and release. Next, press the Volume Down key and release it again. Step 2 – The next part of the process is to hold the button on the right side. Let the iPhone finish restarting. Enable cellular data and check network speed. Check again Fix 2 – Change data mode While 5G offers better network speeds, it works better when the signal is weaker

The vitality of super intelligence awakens! But with the arrival of self-updating AI, mothers no longer have to worry about data bottlenecks The vitality of super intelligence awakens! But with the arrival of self-updating AI, mothers no longer have to worry about data bottlenecks Apr 29, 2024 pm 06:55 PM

I cry to death. The world is madly building big models. The data on the Internet is not enough. It is not enough at all. The training model looks like "The Hunger Games", and AI researchers around the world are worrying about how to feed these data voracious eaters. This problem is particularly prominent in multi-modal tasks. At a time when nothing could be done, a start-up team from the Department of Renmin University of China used its own new model to become the first in China to make "model-generated data feed itself" a reality. Moreover, it is a two-pronged approach on the understanding side and the generation side. Both sides can generate high-quality, multi-modal new data and provide data feedback to the model itself. What is a model? Awaker 1.0, a large multi-modal model that just appeared on the Zhongguancun Forum. Who is the team? Sophon engine. Founded by Gao Yizhao, a doctoral student at Renmin University’s Hillhouse School of Artificial Intelligence.

Tesla robots work in factories, Musk: The degree of freedom of hands will reach 22 this year! Tesla robots work in factories, Musk: The degree of freedom of hands will reach 22 this year! May 06, 2024 pm 04:13 PM

The latest video of Tesla's robot Optimus is released, and it can already work in the factory. At normal speed, it sorts batteries (Tesla's 4680 batteries) like this: The official also released what it looks like at 20x speed - on a small "workstation", picking and picking and picking: This time it is released One of the highlights of the video is that Optimus completes this work in the factory, completely autonomously, without human intervention throughout the process. And from the perspective of Optimus, it can also pick up and place the crooked battery, focusing on automatic error correction: Regarding Optimus's hand, NVIDIA scientist Jim Fan gave a high evaluation: Optimus's hand is the world's five-fingered robot. One of the most dexterous. Its hands are not only tactile

The U.S. Air Force showcases its first AI fighter jet with high profile! The minister personally conducted the test drive without interfering during the whole process, and 100,000 lines of code were tested for 21 times.

Recently, the military circle has been overwhelmed by the news: US military fighter jets can now complete fully automatic air combat using AI. Yes, just recently, the US military’s AI fighter jet was made public for the first time and the mystery was unveiled. The full name of this fighter is the Variable Stability Simulator Test Aircraft (VISTA). It was personally flown by the Secretary of the US Air Force to simulate a one-on-one air battle. On May 2, U.S. Air Force Secretary Frank Kendall took off in an X-62AVISTA at Edwards Air Force Base. Note that during the one-hour flight, all flight actions were completed autonomously by AI! Kendall said - "For the past few decades, we have been thinking about the unlimited potential of autonomous air-to-air combat, but it has always seemed out of reach." However now,

Single card running Llama 70B is faster than dual card, Microsoft forced FP6 into A100 | Open source Single card running Llama 70B is faster than dual card, Microsoft forced FP6 into A100 | Open source Apr 29, 2024 pm 04:55 PM

FP8 and lower floating point quantification precision are no longer the "patent" of H100! Lao Huang wanted everyone to use INT8/INT4, and the Microsoft DeepSpeed ​​team started running FP6 on A100 without official support from NVIDIA. Test results show that the new method TC-FPx's FP6 quantization on A100 is close to or occasionally faster than INT4, and has higher accuracy than the latter. On top of this, there is also end-to-end large model support, which has been open sourced and integrated into deep learning inference frameworks such as DeepSpeed. This result also has an immediate effect on accelerating large models - under this framework, using a single card to run Llama, the throughput is 2.65 times higher than that of dual cards. one

AI startups collectively switched jobs to OpenAI, and the security team regrouped after Ilya left! AI startups collectively switched jobs to OpenAI, and the security team regrouped after Ilya left! Jun 08, 2024 pm 01:00 PM

Last week, amid the internal wave of resignations and external criticism, OpenAI was plagued by internal and external troubles: - The infringement of the widow sister sparked global heated discussions - Employees signing "overlord clauses" were exposed one after another - Netizens listed Ultraman's "seven deadly sins" Rumors refuting: According to leaked information and documents obtained by Vox, OpenAI’s senior leadership, including Altman, was well aware of these equity recovery provisions and signed off on them. In addition, there is a serious and urgent issue facing OpenAI - AI safety. The recent departures of five security-related employees, including two of its most prominent employees, and the dissolution of the "Super Alignment" team have once again put OpenAI's security issues in the spotlight. Fortune magazine reported that OpenA

iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos Jul 18, 2024 am 05:48 AM

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

Open-Sora comprehensive open source upgrade: supports 16s video generation and 720p resolution Open-Sora comprehensive open source upgrade: supports 16s video generation and 720p resolution Apr 25, 2024 pm 02:55 PM

Open-Sora has been quietly updated in the open source community. It now supports video generation up to 16 seconds, with resolutions up to 720p, and can handle text-to-image, text-to-video, image-to-video, and video-to-video of any aspect ratio. and the generation needs of infinitely long videos. Let's try it out. Generate a horizontal screen Christmas snow scene, post to B site and then generate a vertical screen, and use Douyin to generate a 16-second long video. Now everyone can have a screenwriting addiction. How to play? Guidance GitHub: https://github.com/hpcaitech/Open-Sora What’s even cooler is that Open-Sora is still all open source, including the latest model architecture, the latest model weights, multi-time/resolution/long-term
