Failover actions
If KX Control is deployed in a cluster and there is a failover event, all the processes that are currently running will attempt to connect to the new leader KX Control process. If a connection to a particular process is not made within a certain time then the unexpected shutdown action for that process will be triggered. This timeout can be configured using the DELTACONTROL_MISSING_PROCS_TIMEOUT environment variable in delta.profile. It is set to 60 seconds by default.
export DELTACONTROL_MISSING_PROCS_TIMEOUT=60It is possible to configure if the unexpected shutdown actions are triggered when the timeout is passed. This can be done via the DELTACONTROL_FAILOVER_ACTIONS environment variable in delta.profile.
export DELTACONTROL_FAILOVER_ACTIONS=ALLThe possible options are
| Value | Description |
|---|---|
| ALL (default) | Unexpected shutdown action triggered for any process that breaches timeout |
| NONE | No unexpected shutdown action triggered for any process that breaches timeout |
| KDB | Unexpected shutdown actions triggered for all except DS_LAUNCH processes |
