Hey GWC - it's been a long time!!!

Quick question, actually, it's more a WVE question but I'm hoping someone has encountered it....

I've created a Health Policy for Excessive Memory and I scripted a custom action it should execute when certain conditions are met.  I
configured the custom action and pointed it to my script (which sends an email to me and the other WAS admins) but I need to test it to make sure it works. 

I found the AdminTask.executeHealthPolicy command but I'm getting a java.lang.NullPointerException error:

WASX7015E: Exception running command: "AdminTask.executeHealthAction
('[-name Excessive_Memory_Alert -node nodeName
-server serverName]')";
  exception information:  java.lang.NullPointerException: java.lang.NullPointerException

I've searched for hours and the only thing I found says it's a known
problem and will be fixed in the next WAS v7
or WAS v8.5 fixpack.

Has anyone found a work around?

Hi Danielle,


  I suppose that your link is (is broken)

  www.ibm.com/developerworks/forum/message...

  have you do the suggested action?

  Have you enable traces in wsadmin?

Hi Gabriel,

Thanks for responding!  My apologies, for some reason cut/paste always breaks the links...

www.ibm.com/developerworks/forums/messag...

And yes, that link is where I got the format for my executable.  The only difference is I wrote it entirely in python....

I enabled wsadmin trace and got the following error:

Danielle,

  I only can say you viewing the traces, that seems like some timeout value is missing. But I don't know....

com.ibm.ws.xd.agent.
httpservice.client.JSONRPCClientImpl.getTimeOutValue

 Has the health policy function more parameters? maybe if exist a function
with more parameters you can try it.


  Have you open a PMR?

regards

Hmmmm....

I'm not sure if there are any parameters missing.  I modeled my script after healthpolicy.py located in the bin directory (minus all the extra fluff we don't need).  Anyway in that script only one parameter is defined for the Memory Leak Condition Health Policy but maybe there is something I may have missed.

Interesting.....

I'll take another look and see if I can't figure out what's causing that timeout error.

Thanks Gabriel!
