1. Define the application callback module. 2. Define the application resource description file. The resource description file name must be the same as the application name and be suffixed. app, such as bank. the app then places the resource description file in the path that erlang can search for. 3. start applicationapplication: start (bank ). compared with Exercise 1, appl 1.

When you deploy an Erlang project under Linux, many of the development processes are done in Windows and then released to Linux, so the testing process is done under the virtual machine. One day, because you want to use Erlang graphical tools such as APPMON, TV, observer, and so on in a virtual machine, it's a whim to use the Windows Erlang connection to a virtual machine to see the running state of the virtual machine.What do I need to prepare?I am i

WebTool minor ProblemsErlang's observation tools such as Crashdump,appmon,cover have two different interfaces: GS (WX) and the Web. These tool follow a certain interface, the user can expand these functions, so that can be integrated into the toolbar or webtool system. It is convenient to use the WebTool online, because it is a web interface, easy to cross the firewall or something.WebTool uses the following interface:However, the default WebTool at s

Erlang tool andCodeLibrary Erlang has a set of common tool libraries: Appmon -Process Group graphical monitoring (on local and remote nodes ). ASN.1 -Supports the ASN.1 basic markup method and the code package at compile time and runtime of the BER, der, and per encoding rules. Compiler -Erlang compiler. Debugger -Graphical Erlang debugger. ERTs -The Erlang runtime system, including virtual machines, garbage collection, and port ing daemon processes.

application is started. The result is tragic. for example, in the following code, the return value of the Start function is the value of the last expression IO: format, and the result is OK, which does not meet the requirements of the application for the result of the Start callback function. start(Startype,Arg) -> demo_sup:start_link(), io:format("demo app start"). Application stop Process To stop the application, the application master first calls module: prep_stop/1 (if any), and then

But the system memory is seriously insufficient, there is no way to start these tools, fortunately, there are Erlang shell.The Erlang shell comes with a lot of useful commands that can be viewed with the Help () method> help().Erlang system memory consumptionTop results show that it is a memory problem, so the first step is to look at the system memory consumption of Erlang first

can add table shards. For convenience, create a function to obtain the frag_dist of the table. (A @ localhost)28> gettableinfo = fun (item)-> mnesia: table_info (Dictionary, item) end. # Fun (A @ localhost)29> getfragnodes = fun ()-> mnesia: Activity (sync_dirty, gettableinfo, [frag_dist], mnesia_frag) end. # Fun Test: (A @ localhost)30> getfragnodes (). [{B @ localhost, 0}, {c @ localhost, 0}, {A @ localhost, 1}] Now you can add a shard. Through the node list returned by getfrag
