Windows中的Erlang-进程增加了吗？

Question

I am using Erlang and have just got started with it. I keep hitting a process_limit in Windows and can't figure out how to increase the process limit ?

I am using WERL.exe and would appreciate the commands to increase this ?

Thanks

In your windows cmd prompt , you can fire up an erlang shell by typing erl on the terminal prompt and hitting Enter . However, this will only work if, you have the erl.exe full path in your windows $PATH environment variable. This should be the folder: C:\\Program Files (x86)\\erl5.8.5\\bin on my machine, for the latest Erlang. I am sure you can find a way to add this to your environment PATH variable, close all terminals and open again and try entering the erl command.

Now, this should happen:

Microsoft Windows [Version 6.1.7600]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\machine> erl
Eshell V5.8.4  (abort with ^G)
1>

Now, to increase the possible number of processes, you add a Flag like this:
erl +P [Maximum No. of Processes] eg If i want to be able to spawn 13421779 processes within the erlang instance then i can issue the command like this

\nMicrosoft Windows [Version 6.1.7600] \nCopyright (c) 2009 Microsoft Corporation.  All rights reserved.  
\nC:\\Users\\machine>  \nEshell V5.8.4 (abort with ^G) \n1>  \n

However, still, as you will realize later, even this maximum number has an upper limit. :)
