1011: ZEMS-EVT-TAKEOVER
ZEMS-TKN-GENTIME, -LOGTIME, -CPU, -PROC-DESC, -PIN, -NODENUM,
and -USERID
are standard EMS tokens described in Section 14, EMS Definitions.
ZSPI-TKN-PROC-ERR (nonshared)
specifies a procedure associated with the event. Here EMS assigns the value of
ZEMS-VAL-CHECKPOINT to 37.
ZEMS-TKN-SUBJECT-MARK (shared)
is the standard EMS token that immediately precedes each subject token. This
event message has one subject token:
ZEMS-TKN-DIST-NAME (nonshared)
is the name of the distributor process. Here it is the name of the new distributor
process.
ZEMS-TKN-TAKEOVER-REASON (nonshared)
is described in Token and Data Type Definitions on page 18-3.
Cause. The primary distributor process, or the CPU in which it runs, failed, and the
distributor backup process has taken over.
Effect. If the primary distributor process failed, an attempt is made to create a new
backup after a 30-second delay. In the case of CPU failure, a new backup is created
30 seconds after the new primary process receives a CPU RELOADED system
message.
Recovery. If the primary process abnormally ended, investigate the event log to
determine why.
