ABSTRACT OF PROBLEM
___________________
During preparation and termination of CRUISE processing, any ECB
usage percentage change has no effect.
 
COMMENTS ON PROBLEM
___________________
Within  CRUISE processing it's possible to change ECB usage per-
centage to react on sudden  system  resource  lacks  or  if  the
system  got  some available resources it's possible to raise the
ECB usage percentage.
 
This can be done with the entry ZFCRU ECB-nn.    The  change  is
recognized  within  the chain chaser (FACE processing) and takes
effect.
 
But if the processing is within the preparation (RESTORE)  proc-
essing  or  the termination (PACK) processing any ECB percentage
change has no effect, because it's not checked.
 
On any system resource shortage  during  preparation  or  termi-
nation there is no chance to change ECB usage percentage.
 
SOLUTION
________
Within  preparation  processing of RESTORE and termination proc-
essing of PACK a possible ECB usage percentage change is checked
and takes immediate effect.
