Re: OBJECT PATCHING

[CRPence <CRPbottle@xxxxxxxxx>]

  Why would a new program need to be in the EPT unless it is part 
of the OS?  Code that is created outside of the OS development, the 
programs in such an application should be created and delivered as 
an LPP using user-state programs.  Not understanding why the LIC 
exception 4401 occurs, is a clear indication that success with 
effecting the patch is probable folly.  Similarly, for understanding 
about why attempts to patch system state would not be functional.

  Had you at least asked internally on the ibmforums.ibm.com 
newgroup [or equivalent brower-based forums]; e.g. on software.os400 
or hardware.iseries?  While it may be interesting to those outside 
IBM to try to /play/ with such things, IMO it is at least somewhat 
inappropriate for someone within IBM to be attempting such nonsense; 
even somewhat odd, to be discussing the topic on a public forum, 
since that makes IBM look incapable of doing their own business. 
You should contact IBM Rochester development team to discuss what 
you are attempting to do, and probably best to discuss what you want 
to do.  I believe the security component provides a tool to 
IBM-support to update the EPT, but it will not assist in making a 
valid signed system state program object.
