ATB208I

Explanation
 Because of the reason indicated by rsncode,
the resource manager notification exit for this logical unit has been
unset. The LU can no longer accept protected conversations (conversations
with a synchronization level of syncpt).
 In the message text:
 luname
The name of the logical unit that can no longer accept protected
conversations.
schedname
The name of the scheduler that uses the specified logical unit.
rsncode
The value passed to the resource manager notification exit for
this LU. This value indicates why the resource manager exits have
been unset. For an explanation of these values, see the description
of field value2 in the parameter list for
the NOTIFICATION exit routine in z/OS MVS Programming: Resource Recovery. 

System action
 The LU continues processing conversations with
a synchronization level of none or confirm. Protected conversations
(conversations with a synchronization level of syncpoint) are terminated
at the time the exits are unset. APPC/MVS will attempt to reset this
LU's resource manager exits, so the LU can resume processing protected
conversations.
