Server Parameters
IGNORELASTEVENT (FALSE)
allows two event collection servers to run simultaneously and thereby improve event
reception performance. IGNORELASTEVENT indicates whether the server should ignore
the last-event display. If the display is ignored, no events are collected for that display and
any requests for service are rejected with a ViewPoint error 325. The default value is
FALSE, meaning that all displays are managed from one server.
Note that this feature is used in the default Pathway configuration to create two servers:
ZVPT-EVNT-COLL, which manages the primary and alternate event displays, and
ZVPT-EVLE-COLL, which manages the last- events display.
Servers: ZVPT-EVNT-COLL
IGNOREPRIEVENT (FALSE)
allows two event collection servers to run simultaneously and thereby improve event
reception performance. IGNOREPRIEVENT indicates whether the server should ignore the
primary-events display. If the display is ignored, no events are collected for that display and
any requests for service are rejected with a ViewPoint error 325. The default value is
FALSE; that is, all displays are managed from one server.
Note that this feature is used in the default Pathway configuration to create two servers:
ZVPT-EVNT-COLL, which manages the primary-events and alternate-events displays, and
ZVPT-EVLE-COLL, which manages the last events display.
Servers: ZVPT-EVLE-COLL
LAST-DISTRIBUTOR-CPU (-1)
provides the cpu number in which ViewPoint runs the last events distributor. If this
parameter is defined with a valid CPU number, ViewPoint uses the value of the parameter;
otherwise, ViewPoint uses the CPU of the server.
Servers: ZVPT-EVLE-COLL
LAST-EVENT-CACHESIZE (10)
provides the number of events retained in the last-events cache for each subject. Newer
events overwrite the oldest for each subject. You can specify a value of 1 through 32767. If
you specify a value less than 1, the value 1 is used.
The value is used each time a new event subject is logged to the last-events database. A new
LAST-EVENT-CACHESIZE value does not take effect for subjects already in the database.
Most subjects eventually expire and are deleted by the ZVPT-GARB-COLL server, but
frequently used subjects might never be deleted.
You might want to clean out the database when changing the cache size so that all subjects
use the new cache size. You can do this with the FUP command PURGEDATA
(EVNTLESB, EVNTLECA) with the files closed.
Servers: ZVPT-EVLE-COLL
LAST-EVENT-MAX-HOURS (72)
provides the maximum age that events in the last-events cache are allowed to attain before
they are deleted by the garbage-collection cleanup task. Possible values are 0 through 32767.
The cleanup task is scheduled to run at the time specified by the parameter CLEANUP-
HOUR.
Servers: ZVPT-GARB-COLL
