Table 4-2. Server Parameters (Page 2 of 2)
Parameter and (Default) Value Description
MAXREPLY
(2048)
nn where nn is the largest reply (in bytes) a server
can generate. This value might affect the
maximum number of simultaneous openers,
due to memory limitations.
MAXREQUEST
(2048)
nn where nn is the largest request (in bytes) a
server can accept. This value might affect the
maximum number of simultaneous openers
due to memory limitations.
MAXWAITERS
(set by MAXLINKS)
nn where nn is the number of simultaneous
WAITQs that can be outstanding at a time.
The value must be less than 500. A value
larger than 500 causes a diagnostic to be
issued and the server to ABEND.
RESERVEDLINKS *
(1)
nn where nn is the number of openers (set by
MAXLINKS) that must be Entry Manager
programs rather than application components.
The number of application components that
can open the Wait Manager is MAXLINKS
minus RESERVEDLINKS.
RESERVELCBS * nn where nn is the number of LCBs that a Wait
Manager reserves for its own use. This
parameter allows the message about
outstanding requests on a process to be
removed. If your Wait Manager typically has a
large number of waiters outstanding, you
should set this parameter to a value that
corresponds to the expected number of
simultaneous waiters.
WAKEUPINTERVAL * nn where nn is the length of time (in seconds) the
Wait Manager sits idle waiting on $RECEIVE.
At the end of this period, the Wait Manager
checks the Queue file to make sure there are
no entries to be processed (entries could be
there if a transaction with a DEQ aborts, for
example). If there are no outstanding
requests, the Wait Manager wakes up every
WAKEUP-INTERVAL and performs a check
on a single opener. One opener is checked
every WAKEUPINTERVAL.
* These parameters apply only to the Wait Manager.
