Switches the event processing server from the master domain
manager to the backup master or vice versa.
Note that
you can run the event processing server also on a workstation installed
as a backup master that runs as a plain fault-tolerant agent.
Syntax
{switcheventprocessor | switchevtp} workstation
Arguments
- workstation
- Specifies the name of the master domain manager or of the backup
master where you want to switch the event processing server. Wildcard
characters are not permitted.
Comments
If you issue the command
from a workstation other than the one where the event processor is
configured, the command uses the command-line client, so the user
credentials for the command-line client must be set correctly.
In case of backup masters the workstation must have the full-status attribute set to on.
Permission to start and stop actions
on cpu objects is required in the security file to
be enabled to run this command.
The correlation state of pending
correlation rule instances is lost whenever the server is switched
off or migrated. If caching of received events is enabled in the configuration
file of the EIF listener, the cached events are lost after the event
processor is switched.
Important: - Before running this command, run planman deploy as a precaution. Do this to make sure that your latest changes or
additions to active event rules are deployed before the event processor
is switched and so avoid the risk that, because of a time mismatch,
the latest updates (sent automatically based on the setup of the deploymentFrequency global option) are received by the
old event processor instead of the new one.
- The master and backup masters designated to run the event processor
should have their clocks synchronized at all times to avoid inconsistencies
in the calculation of the time interval of running event rules. In
fact, if the event processor is switched to a not-synchronized computer,
timeout actions in the process of being triggered might undergo unexpected
delays. Use a Network Time Protocol (NTP) server to keep all clocks
synchronized.
