Question: Why can't I configure a global scan in the service tier in spring?For example: The name of my total project in a project is called Com.shop, we are in the configuration Applicationcontext-service.xml, the package scan code is as follows:beans Xmlns= "Http://www.springframework.org/schema/beans" xmlns : Context= "Http://www.springframework.org/schema/context" .../omitted

In some cases, because it is the C/s architecture, from the previous stand-alone system to the current 11.2 of the RAC, if the client IP address to modify the workload is too large, but also unrealistic, generally recommended directly modify the scan IP address and before, so as to achieve direct business access scan IP implementation applications do not need to be individually configured.

Due to field application needs, the newly configured Oracle RAC environment needs to be added with 2 Scanip addresses, 10.138.129.106 and 10.138.129.107.
Pre-configuration scenario:

The Cost calculation formula for full table scan is as follows: Cost (# SRds * sreadtim + # MRds * mreadtim + CPUCyclescpuspeed) sreadtim: the number of reads per block is 0 during full table scan, # SRds indicates the number of reads per block. In the cost of full table scan, the CPU consumption is actually very small and negligible, so the formula for full tabl
The port is the current computer and outside the channel, so once the hacker locks the target computer, it will scan the computer is already open port, so as to get more useful information. Scan destination computer ports generally use Superscan, X-scan, and so on.First, the principle of port scanningBefore scanning the port, the user must understand how the port
Enterprise Port Scan Policy
1, the purpose of port scanning for the computer system located in the network, a port is a potential communication channel, that is, an intrusion channel. Port scanning of the target computer can get a lot of useful information to discover the security vulnerabilities of the system. It can make the system users understand what services the system is providing to the outside world, thus providing a reference means for the

Of course, some blind spots are also in the process of work and exploration slowly some, now also willing to carry forward the dedication of the blog park, to come out and share with you.Open the door and go straight into the question.Have you ever had the same doubts as me when looking at the execution plan?

Disk self-healing features NTFS utilizes a "self-healing" system that automatically detects and fixes logical and physical errors on the hard disk. In the FAT16 and FAT32 times, we need to use the ScanDisk program to mark bad sectors on disk, but when errors are found, the data is often written in bad sectors, and the damage is done.
Computer illegal shutdown, accidental power outages and so on, the next time the boot or restart, Windows will perform hard disk partition detection,
On the one hand, the percentage of rows returned is small or full scan is possible, and on the other hand, the percentage of rows returned is large, and it is possible that full scans should not be used.
Here's an example of how the optimizer chooses to scan differently, even though the percentages of the data returned are small, but the data is stored in a different way. First, you create two of the same
Indexes are accessed mainly by index lookup, index scan.
