mailbox of the receiving process. When the process enters the message receiving again, messages accumulated after timeout may be processed. Therefore, it is best to flush the mailbox of the process before receiving messages. Monitor_node (remotenode, true) is used to monitor remote nodes. When a monitored remote node crashes, the monitoring process receives the {nodedown, remotenode} message. You can use the BIF function node (ARG) to query the node on which a process (PID), reference, or por

Reprinted: http://blog.csdn.net/minyskirt/article/details/5031221 Erlangweb is an open-source HTTP-based application framework. It uses the Erlang language to quickly and concisely build Web applications. However, currently, this framework only supports Linux platforms. Its official site is http://erlang-web.org /.

Reprinted: http://www.cnblogs.com/cobbliu/archive/2012/03/10/2388556.html Erlang is definitely a niche language, but its future development prospects are incalculable because it can solve the difficult problem of parallel computing in traditional languages. Erlang is a function type (a variable can only be assigned once), a strong type, and a dynamic type (the variable type is determined at runtime and can be executed only after the code is compiled. It is different from Python, Ruby, and so o

Getting startedfirst steps The best way to get going with rebar is to use it to construct andBuild a simple Erlang application. First, let's create the directoryOur application: $ Mkdir MyApp; CD MyApp Now, download the rebar binary into our application. Note: If youHave rebar available on your shell path, that will work equally well. $ Wget http://bitbucket.org/basho/rebar/downloads/rebar; chmod U + x rebar Now, we'll use rebar's templating system to create the skeletonOur application:

That is to say, if the user has relevant permissions for the database, the access permissions to Table and Column are not verified. After viewing the DB_PRIVS table, the hadoop user has the Select permission for the database to be accessed, so there is no problem in accessing the database in the traditional CLI mode.

The effect is the same as that of the SMTP protocol in the previous two days. However, it is much more convenient and easier to use javamail. To run this program, two Java packages are required: mail. jar and activation. Jar. These two packages are easy to run, so I will not talk about them here. The core classes of javamail APIs used in this program include Session, message, address, verification program, and transmission. The functions are as follows: SessionThe session class defines a basic m
