CommServe Failover Configuration Parameters
The following table lists the commonly used configurable parameters in the cvfailover.cfg file.
|postStartScript||Specifies the path to the script that you run after starting the failover operation. Example: c:\\test\\script.bat|
|backupPeriodMinutes||Specifies the time interval frequency for database replication.|
|maxFailedStarts||Specifies the maximum number of attempts allowed to start services on the active node after a failover. If the number of attempts exceeded this value, automatic failover is disabled and manual intervention is required.|
|preStopScript||Specifies the path to the script that is run before the failover operation stops. Example: c:\\test\\script.bat|
|reconnectTimeoutMinutes||Specifies the time interval before reconnecting the active node.|
|postStopScript||Specifies the path to the script that is run after the failover operation stops. Example: c:\\test\\script.bat|
|customTtlTimeout||Specifies the time interval before the passive node is reconnected to the active node. After the time limit expires, a notification email is sent to the specified email addresses and the failover operation starts.|
|servicesDownTimeoutMinutes||Specifies the time limit before the services are stopped on the passive node.|
|preStartScript||Specifies the path to the script to run before starting the failover operation. Example: c:\\test\\script.bat|
|servicesScanPeriodMinutes||Specifies the time interval before verifying that services are running on the active node.|
|alertDebug||Enter 1 to include additional information in the alert emails for troubleshooting purposes.|
The cvfailover command also supports the following configuration options.
cvfailover.cmd [newActiveNodeId] [/h] [/f] [/m] [/a]
|newActiveNodeID||Initiates the manual failover to the specified ID. Enter 1 for production or 2 for standby CommServe host.|
|/f||Resets an in-progress failover if it appears to be hung.|
|/m||Enables manual failover of the CommServe host.|
|/a|| Enables automatic failover of the CommServe host.
When using automatic failover mode, failover operations are triggered for non-disaster scenarios, such as process crashes or service restarts. Therefore, we recommend that you set the manual failover mode and failover the CommServe manually in the event of a disaster.
Also, if you are using automatic failover mode, switch to manual mode before performing any maintenance tasks, such as installing updates on the CommServe or on the witness server hosts.
|/DisableLogShipping||Disables log shipping operations.|
|/EnableLogShipping||Enables log shipping operations from active node to the passive node.|
