ADD CLASS
ZCHKPNT-SIZE
specifies the maximum amount of data in units of K octets that may be sent 
between two minor synchronization points by the RTS. This value is in the 
range 1 through 30. This attribute is used by OSI/MHS when negotiating the 
checkpoint size.
ZWNDW-SIZE
is the maximum number of outstanding minor synchronization points before 
data transfer is suspended by the RTS. The range of values is 1 through 100.
ZSAFE-STORE-WNDW
is the number of minor synchronization points sent before recovery information 
is written to disk. The range of values is 0 through 100. If the value is 0, 
information for minor synchronization points is never written to disk.
ZDELAY-TIME
is the time to delay before attempted recovery after a session failure. It is also 
used as the time interval between recovery attempts. The range of values is 
1 through 36000 seconds.
ZURGENT-COUNT
specifies the maximum number of urgent messages the MRP can have on its 
queue for a given destination before it attempts to establish an association with 
the adjacent MTA. The MR group can initiate an association with an adjacent 
MTA before this count if a message has been on the queue for ZURGENT-
TIME length of time. This value is in the range 1 through 25.
ZURGENT-TIME
specifies the maximum time the MR group can wait after an URGENT message 
arrives on its queue for an adjacent MTA, before it must attempt to establish an 
association with the adjacent MTA. The MR group can initiate an association 
with an adjacent MTA before this time expires if the ZURGENT-COUNT 
threshold is reached for the adjacent MTA. This value is expressed in seconds 
and has a range of 1 through 36000.
ZNORMAL-COUNT
specifies the maximum number of normal messages that the MTA can have on 
its queue for a given destination before it attempts to establish an association 
with the adjacent MTA. The MR group can initiate an association with an 
adjacent MTA before this count if a message has been on the queue for 
ZNORMAL-TIME length of time. This value is in the range 1 through 25.
ZNORMAL-TIME
specifies the maximum time the MR group can wait after a NORMAL message 
arrives on its queue for an adjacent MTA, before it must attempt to establish an
