For example, in the same line range with the same session, in the same method with the same session, so that we can use the session to cache good data. But, what I want to say is not the cache, and listen to my one by one Tao.Recently tried spring3.0.2+struts2.18+hibernate3.3.2 learning to build a Web project, there has been a rather depressing probl

Through recent studies, I finally have some new understanding of the DNS problem in active Directory, and now I would like to share with you our learning experience! All of us should know that in a domain environment, users and computers locate the DC (domain control) domain controller through the SRV records in DNS, if the DNS server fails, (set up on a stand-alone server or with a DC when the DC is not discussed), Many of us will think that this SR

Active support is a set of libraries provided with rails, active support extends some of the classes in Ruby, and this time we'll look at some of the most common features. 1. Extension of the number type The Fixnum class adds two methods: even and odd? The scaling method is also added: Puts 20.bytes #=> 20 Puts 20.kilobytes #=> 20480 Puts 20.megabytes #=> 20971520 Puts 20.gigabytes #=> 21474836480 P

The Active Directory series has actually ended, but recently I found the SYSVOL and Netlogon two shared folders suddenly lost in an accidental experimental environment, thinking that this was due to some misoperation, so it's time to finish up the series here. Describe the whole process of what happened: I set up a two-site parent-child domain environment, where the Beijing site is a root dc,n1.net.com, Shanghai site has a second root dc,n2.net.com,

Operations master roles ================================== When a change is made on the domain, the change will be copied to all domain controllers in the domain. some modifications, such as schema modifications, will be copied to the entire forest. this type of replication is calledMulti-body replication (Multimaster replication ). During the multimaster replication process, if the update source occurs on both domain controllers and the same attribute of the same object is modified, a replicat

Passive objects are normally put there and will not be moved, waiting for other execution threads to call and then will be executed. Active objects generally contain execution threads and can actively execute code. 1. The active object is based on the ace_task class and provides the execution thread. 2. When some code to be executed is to be executed, it should be put into a queue. Then, when the executio
