Finally put OCP DBA's course all finished, tired Ah! Overall Oracle certification is worth the test. I have CCNP, MCSE certificate, but through the DBA examination, feel not only deepened the understanding of modern databases, but also enrich the knowledge structure of computer science. I think, in some ways, Oracle databases even have some operating system capabilities.
Oracle's exams, there are quite a few things to remember, the exam requirements
, which is important, which is what we have to master the foundation. It's not possible to tell you this with just one keyword. Through the book, the author will put these knowledge systematically linked together, to tell you the above information, so that you can systematically and comprehensively improve. And the content of the book is relatively, more professional than online, more practical. Finally, by the way, in terms of training, yes, I have always stressed that junior network administr
CCNP preparation is imminent, with the book "Cisco Network Laboratory-routing, Exchange Experiment Guide" review of these basic experiments, simulation software with the packet Tracer 5.0.

For example: Enter a show ip eigrp topology command:
P 10.55.103.0/24, 1 successors, FD is 6049536via 10.220.100.1 (6049536/5537536), Serial3/0via 10.55.100.14 (52825600/281600), Tunnel55
Note that this EIGRP routing protocol has two routes routed to this network. However, this router accepts only one of the shortest routes in the routing table. Here is an example of a routing table entry:

human beings. In turn, the shell is, in fact, what humans tell the machine at some point, what it does, what it does, and what it does, except that the operating system is made up of the basic elements of the file. Therefore, the shell is to find the required files, that is, what behavior to use. And a certain moment, the completion of what can be understood as parameters, to achieve the effect depends on the user's familiarity with a variety of commands, because a number of commands (a number
Cisco and other companies, and then learn the practical experience that using experience to support certificates is the only way to get a job promotion. There is a problem: some people pay little attention to the real problems in real work. I've never heard of any company that needs a CCNA level technician, so having a higher-level Cisco certificate can help you provide the company with enough technology to solve real-world network problems, and only the CCNA certificate doesn't mean you can ha

Attention:
1, in the CCNP Learning Guide P91 Page said key-string the first character can not be a number, but the experimental results can be used as a pure digital password!
2, the name behind the key chain only valid locally, the routers can not be consistent.
3, key ID must be globally consistent, otherwise the certification is not successful, in each EIGRP package contains the value, you can grab the bag to see the carrying key ID.

module is compiled into a C function, then, the main function call function and function call function are used to compile a large-scale C program. Therefore, C program = Main Function + subfunction. Therefore, we should pay special attention to understanding and applying the definition, call, and return of values of functions, and consolidate them through machine debugging.

fact, many of the things php does are written lib, and php has made a wrapper.
So let's learn everything. A small company is quite good. Looking for a small company that is more formal than a large company, a large company can only learn for a long time and learn to be a person at most. The php video tutorials for the subject should not be comprehensive.
Complete is the first stage of the php video tutorial, that is, the necessary knowledge of the front-end.
