A company used two ibm850 x6 servers, installed rhel 6.4 system, one ibm ds5020 storage, and oracle 11G rac database cluster. Due to poor customer management, the two systems ransomized the virus, and the system oracle files were all virus.

Solution: After communicating with the customer, Zhaobai data recovery project determined that the important files of the database were stored in the storage, and the asm disk should not be damaged.
1. Map the storage to a server, and physically back up the storage at the first time, back up to a 4T hard disk. After the backup is completed, the storage disconnects all connections to ensure the security of the stored data.
2. The backup asm disk is analyzed, and 3 asm disks are found. After analysis by the oracle asm data recovery software, it is found that the customer’s important data files and log files and archive backup files can be restored.
3. Speaking of file recovery to an empty hard disk, the data file is 800G together.
4. Set up a single machine Oracle 11G, restore the data files to a single machine, the data is completely restored after the customer is verified, the customer is very satisfied, and lasted 48 hours, the customer is very satisfied.

Can RFID be implemented for forklift trajectory record?

We have one plant which is 300 meters long and 200 meters wide. We need to achieve 30 forklift trajectory record. Can RFID be implemented? How much does it cost?

RFID does not work. Use the electronic fence would be good, with the positioning algorithm.

Electronic fence is something similar to GPS, base on the principle of the station positioning. Those 4 corner is a small base station, through the algorithm positioning.

3-in-1 charge cable 2A or 0.65A?

Is the 2A charge cable with 3 charging sub-cables always be 2 amp in actual usage?

The fact is that 2A is only valid when there is only one smart device is charged.

When 2 device are charged,the current for each is not more than 1A.

When 3 sub-cables are used for 3 smart phones or tablet or game machine,the current for each is 0.65A.
