Enabling and disabling maintenance mode
Any recovery group in Continentalclusters is moved into maintenance mode using cmrecovercl
command with —d option. The —d flag is used to disable recovery of the recovery groups.
For Example:
# cmrecovercl —d recovery_group1
Any recovery group in Continentalclusters is moved out of maintenance mode using cmrecovercl
command with —e option. The —e flag is used to enable recovery of the recovery groups.
For Example:
# cmrecovercl —e recovery_group1
Configuring targets for notifications sent by Continentalclusters
Continentalclusters sends notifications in XML format. Here is a sample XML notification message
is shown below:
<ContinentalclustersEventNotification> <NotificationTime> Fri Nov 9 01:25:56 2012
</NotificationTime><NotificationEvent> The cluster primary_cluster is at event level alert with status up for
0 second(s).
</NotificationEvent <NotificationMessage> Primary Cluster status up </NotificationMessage>
</ContinentalclustersEventNotification>
The user configured notification message in Continentalclusters configuration file is enclosed
between <NotificationMessage> and </NotificationMessage> tags. The notification targets must
be configured appropriately to parse this message.
