The Delete  Grace  Key command  is a  companion  command to  CRTGRCKEY.
CRTGRCKEY  is used  to  allow the  use  of the  TAA Tools  for  a grace
period  on a system that does not have  a valid license.  CRTGRCKEY may
only be  used  once on  a  system unless  a  reset occurs.    DLTGRCKEY
provides a  reset function, but  requires a special software  code that
may be requested from the TAA Productivity Tools owner.

A  typical scenario for  the use of  DLTGRCKEY is when  a backup system
exists who's only  function is for  usage if a  disaster occurs to  the
production system.   The backup system would normally not  have a valid
TAA  license.  If  a disaster occurred,  operations could begin  on the
backup system and  CRTGRCKEY could be  used to allow  TAA functions  to
run  while  the  production  system  is  being  recovered.    When  the
production  system is recovered,  the backup  system would  remain idle
again.   Because  CRTGRCKEY may  only be used  once on  a system unless
reset, it could  not be used again  if another disaster occurred.   The
purpose  of DLTGRCKEY  is to  reset the  function to  allow the  use of
CRTGRCKEY if it is needed again.

You  must contact  the TAA  Productivity Tools  owner for  the software
code value to be  entered on DLTGRCKEY.   DLTGRCKEY must be entered  on
the date  you describe  to the  TAA Productivity  Tools owner that  you
will  use  the command.    Normally, this  would  be the  same  day you
contact the TAA Productivity Tools owner.

Note that if  you use the backup  system on a  regular basis (not  just
in a disaster  recovery situation) and  want to run TAA  functions, you
will need a full license for the backup system.

You must have *ALLOBJ special authority to use DLTGRCKEY.

A typical command would be:

             DLTGRCKEY   CODE1(xxxx) CODE2(yyyy) ...

DLTGRCKEY may  be used when operating  with a grace key, or  a valid or
invalid license.  The license is not changed by DLTGRCKEY.
