The ADD PTNR-MODE Command
MAXAUTOACT attribute is greater than the value of the MINCONWINNER
attribute after the CNOS command is negotiated, only the number of sessions
specified by the MINCONWINNER attribute are pre-established. The valid range is
from 0 through 1024, and the default value is 0.
RCVWINDOW number
specifies the number of request/response units (RUs) that SNAX/APC can receive
from the partner LU at one time. The partner LU will not send more RUs to
SNAX/APC until SNAX/APC sends a pacing response indicating that it can receive
another pacing window. The valid range is from 0 to 63, and the default value is 0
(which specifies that pacing is not used).
SENDWINDOW number
specifies the number of request/response units (RUs) that SNAX/APC can send to
the partner LU at one time. SNAX/APC will not send more RUs to the partner LU
until the partner LU sends a pacing response indicating that it can receive another
pacing window. The valid range is from 0 to 63, and the default value is 0 (which
specifies that pacing is not used).
Considerations
•
If the local LU is a parallel-session LU (that is, if MAXSESSION is set to be greater
than 1), the default PTNR-MODE object SNASVCMG is automatically added to the
PTNR-LU object at the time PTNR-LU is added, with the following attribute
settings:
MODENAME = SNASVCMG
DEFAULTMAXINRUSIZE = Value of MAXINRUSIZE or 256
DEFAULTMAXOUTRUSIZE = Value of MAXOUTRUSIZE or 256
DEFAULTMAXSESSION = 2
DEFAULTMINCONWINNER = 1
DEFAULTMINCONLOSER = 1
MAXAUTOACT = 1
RCVWINDOW = 7
SENDWINDOW = 7
•
Only the following commands can act upon the PTNR-MODE object named
SNASVCMG:
ABORT
INFO
START
STATS
STATUS
STOP
•
Maximum RU (request unit) size is limited by the underlying access method.
SNAX/XF and SNAX/CDF support RUs up to 4,096 bytes. SNAX/APN supports
RUs up to 16,000 bytes.
•
Because SNAX/APC is unable to find the upper limit of the underlying SNAX
access method (such as SNAX/APN, SNAX/XF, or SNAX/CDF) of an LU until the
