With the in-depth development of bank datasets, various business data is centrally processed. As the business continues to expand, we may need to expand the old data center and build a new center. In this case, we need to migrate the data center. In fact, for larger data centers, disaster recovery technology is often used to migrate data and the original data center is used as the backup center.
How can we ensure that data is not lost during data center migration? How can we ensure that the bu
VMware's parent-disk storage manufacturer EMC Corporation held a strategic forum for financial Investors in Boston, and at the opening ceremony of the "Analyst Conference", the Chairman of EMC, President and CEO Joe Tucci, delivered his speech."As I have said before, we have never tried to differentiate between these two companies, nor do we differentiate our strategies," Tucci stressed. We will pay more at

This system is a hybrid system composed of CBR and RBR. The system structure is shown in the following figure. The core of the system is inference machine, reasoning machine according to the user input fault description, can not only transform the fault description into a new case, so as to carry out the operation of the case library, but also can transform the fault description into the fact, the rule base operation. However, the status of CBR and RBR is not equal, the CBR

ESDUsing electrostatic gun test, contact voltage ±6kv, the whole box and the internal visible metal parts are detected;Air discharge positive and negative 8KV, detection of the box and the internal metal parts (such as Board jam body), the special detection of 220V power Plug and switch place.Note: The contact discharge and air discharge test is different from the electrostatic gun tip, contact discharge tip for
name of the string, the name of the identifier. The way to create a Symbol object is to precede the name or string with a colon:Create a Symbol object, for example:: Foo:test: "ABC" #结果是: "I am a Boy"String is a string, why do you have the name of the string? This is because a string is also an object in Ruby, a string object. Both the structure and the operation and the Symbol object are different.7, in Ruby each object has a unique object identifier (Identifier), you can use the Object_ID met
