Oracle数据库默认数据库监听与连接端口是1521, 但是有时候项目中需要更改默认端口,,这样做很多时候客户要求,基于安全考虑. 以Oracle 11g 为例, 更改Listener的端口大致需要以下几步:
 
1. 通过命令行查看当前Listener的状态
 
c:\>lsnrctl status
 
执行以后,显示内容一般会告诉你,当前Listener与那些数据库实例相关联
 
2. 执行命令停止Oracle Listener服务
 
c:\>lsnrctl stop
 
执行该命令,停止Oracle监听服务,
 
3. 打开listener.ora与tnsnames.ora文件修改端口号,同时要在listener.ora文件
 
中加入SID注册内容如下:
 
SID_LIST_listener_name=
  (SID_LIST=
  (SID_DESC=
    (GLOBAL_DBNAME=global_database_name)
    (SID_NAME=sid)
    (ORACLE_HOME=oracle_home))
  (SID_DESC=...))
两个文件文件夹地址 - $ORACLE_HOME/network/admin/
 
保存修改以后的文件
 
4. 在windows命令行中执行
 
lsnrctl start
 
你会发现Oracle 监听服务重新启动, 并且关联到你指定的SID服务启动
 
5. 验证connection
 
c:\>sqlplus /nolog
 
SQL:\> connect system/manager@SID
 
如果出现成功连接字样,说明端口更改已经成功
 
注意点:
 
默认情况下listener.ora文件中没有包含静态注册服务Section内容
 
一定要手工加上,而且一定格式正确. 否则就会得到如下错误:
 
TNS-12560: TNS:protocol adapter error
 TNS-00530: Protocol adapter error

这个时候一定记得检查修改的文件!!

Open source! Beyond ZoeDepth! DepthFM: Fast and accurate monocular depth estimation! Open source! Beyond ZoeDepth! DepthFM: Fast and accurate monocular depth estimation! Apr 03, 2024 pm 12:04 PM

0.What does this article do? We propose DepthFM: a versatile and fast state-of-the-art generative monocular depth estimation model. In addition to traditional depth estimation tasks, DepthFM also demonstrates state-of-the-art capabilities in downstream tasks such as depth inpainting. DepthFM is efficient and can synthesize depth maps within a few inference steps. Let’s read about this work together ~ 1.

Use ddrescue to recover data on Linux Use ddrescue to recover data on Linux Mar 20, 2024 pm 01:37 PM

DDREASE is a tool for recovering data from file or block devices such as hard drives, SSDs, RAM disks, CDs, DVDs and USB storage devices. It copies data from one block device to another, leaving corrupted data blocks behind and moving only good data blocks. ddreasue is a powerful recovery tool that is fully automated as it does not require any interference during recovery operations. Additionally, thanks to the ddasue map file, it can be stopped and resumed at any time. Other key features of DDREASE are as follows: It does not overwrite recovered data but fills the gaps in case of iterative recovery. However, it can be truncated if the tool is instructed to do so explicitly. Recover data from multiple files or blocks to a single

How to use Excel filter function with multiple conditions How to use Excel filter function with multiple conditions Feb 26, 2024 am 10:19 AM

If you need to know how to use filtering with multiple criteria in Excel, the following tutorial will guide you through the steps to ensure you can filter and sort your data effectively. Excel's filtering function is very powerful and can help you extract the information you need from large amounts of data. This function can filter data according to the conditions you set and display only the parts that meet the conditions, making data management more efficient. By using the filter function, you can quickly find target data, saving time in finding and organizing data. This function can not only be applied to simple data lists, but can also be filtered based on multiple conditions to help you locate the information you need more accurately. Overall, Excel’s filtering function is a very practical

Google is ecstatic: JAX performance surpasses Pytorch and TensorFlow! It may become the fastest choice for GPU inference training Google is ecstatic: JAX performance surpasses Pytorch and TensorFlow! It may become the fastest choice for GPU inference training Apr 01, 2024 pm 07:46 PM

The performance of JAX, promoted by Google, has surpassed that of Pytorch and TensorFlow in recent benchmark tests, ranking first in 7 indicators. And the test was not done on the TPU with the best JAX performance. Although among developers, Pytorch is still more popular than Tensorflow. But in the future, perhaps more large models will be trained and run based on the JAX platform. Models Recently, the Keras team benchmarked three backends (TensorFlow, JAX, PyTorch) with the native PyTorch implementation and Keras2 with TensorFlow. First, they select a set of mainstream

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

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

Alibaba 7B multi-modal document understanding large model wins new SOTA Alibaba 7B multi-modal document understanding large model wins new SOTA Apr 02, 2024 am 11:31 AM

New SOTA for multimodal document understanding capabilities! Alibaba's mPLUG team released the latest open source work mPLUG-DocOwl1.5, which proposed a series of solutions to address the four major challenges of high-resolution image text recognition, general document structure understanding, instruction following, and introduction of external knowledge. Without further ado, let’s look at the effects first. One-click recognition and conversion of charts with complex structures into Markdown format: Charts of different styles are available: More detailed text recognition and positioning can also be easily handled: Detailed explanations of document understanding can also be given: You know, "Document Understanding" is currently An important scenario for the implementation of large language models. There are many products on the market to assist document reading. Some of them mainly use OCR systems for text recognition and cooperate with LLM for text processing.

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.
