<DIV dir=ltr><FONT face="Courier New" color=#000000 size=2>Hi,</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>I believe the answer to your question is in, as you seem to be</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>suspecting, (3).</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>The simple-one-for-one is not meant for what I believe you</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>want to do. A child of a simple-one-for-one is not expected</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>to be managed that much in detail on command by its supervisor.</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>I guess you have been "attracted" to the possibility to start</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>children (dynamically) after the creation of the supervisor.</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>And it seems very easy to start alot of the same kind of process</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>children!?</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>You can do this almost as easy with a regular one-for-one</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>supervisor. You simply start a one-for-one without any "regular"</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>children. Then you add what ever children you need as dynamic</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>children. Then you can manage them (from a process outside the</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>hierarchy) as necessary. Your only "trouble" would be that</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>you need to come up with a (within this supervisor) unique</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>name for each and every one of them.</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2>Hope this puts you on a track to solving your problem.</FONT></DIV>

<DIV>
<DIV><FONT face=Arial size=2>Hi All,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Scenario:</FONT></DIV>
<DIV><FONT face=Arial size=2>simple_one_for_one supervisor supervising for bunch of fsms (gen_fsm).</FONT></DIV>
<DIV><FONT face=Arial size=2>Need to restart all the childs (fsms) under that simple_one_for_one supervisor.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Questions:</FONT></DIV>
<DIV><FONT face=Arial size=2>1.) Are there any way to restart the childs (fsms) one by one?</FONT></DIV>
<DIV><FONT face=Arial size=2>2.) Are their any way to restart the simple_one_for_one supervisor instead of above 1 ? so the childs will restart automatically.</FONT></DIV>
<DIV><FONT face=Arial size=2>3.) What is the proper way if above 1 & 2 methods are not suit for the task.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>NOTE: Erlang Manual Says ...</FONT></DIV>
<DIV><FONT face=Arial size=2>The functions terminate_child/2, delete_child/2 and restart_child/2 are invalid for simple_one_for_one supervisors and will return {error,simple_one_for_one} if the specified supervisor uses this restart strategy.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in Advance</FONT></DIV>
