Adjusting the Maximum Number of Associations
Adjusting the Maximum Number of Associations
If you see error messages indicating that association requests from applications are
failing, you may be able to solve the problem without adding processes. The maximum
number of associations an FTAM initiator or responder process can make is determined
by the MAXASSOC attribute of the process. For initiators, the MAXASSOC attribute
indicates the number of concurrent associations allowed between this initiator process
and remote responders. For responders, the attribute specifies the maximum number of
associations between remote initiators and this responder. Note that for responders, the
configured maximum number of outstanding attaches (MAXATTACH) poses an
additional constraint. The MAXATTACH is described in Adjusting the Maximum
Number of Attaches on this page.
Check the number of current associations and the maximum number of associations for
the process, as described in Detecting the Need for Additional Processes
on page 5-12.
If the process has reached the maximum number of allowable associations, an
alternative to adding another process is to change the MAXASSOC attribute so the
existing process can accommodate more associations.
For example, to increase to 10 the maximum number of associations for the responder
process FTR2, issue the following ALTER PROCESS command:
ALTER PROCESS $AMGR.#FTAMR.FTR2, MAXASSOC 10
For more information on the MAXASSOC attribute and altering process configurations,
see Controlling System Performance on page 3-33 and Changing Process Configurations
on page 3-58.
Adjusting the Maximum Number of Attaches
Under most circumstances, it is recommended that the number of outstanding attach
operations for a responder process, determined by the MAXATTACH attribute, be set
equal to the value of the MAXASSOC attribute for the process. Therefore, if you
increase MAXASSOC for a responder process, you should usually increase
MAXATTACH to the same value, to reduce the possibility of rejected attaches. The
value configured for MAXATTACH cannot be greater than the value of MAXASSOC.
On the other hand, if errors indicate that your responder process is short on memory
space, you might want to decrease the value of MAXATTACH.
The following command adjusts the maximum number of attaches to the example
responder FTR1:
ALTER PROCESS $AMGR.#FTAMR.FTR1, MAXATTACH 10

Configurations on page 3-58.
