27.4.2. Taking a Site Offline (Library Mode)

In Red Hat JBoss Data Grid's Library mode, use the backupFor element after defining all back up sites within the backups element:

<backup>
        <takeOffline afterFailures="${NUM}"
                     minTimeToWait="${PERIOD}"/>
</backup>

<backup>
        <takeOffline afterFailures="${NUM}"
                     minTimeToWait="${PERIOD}"/>
</backup>

Add the takeOffline element to the backup element to configure automatically taking a site offline.

The afterFailures parameter specifies the number of times attempts to contact a site can fail before the site is taken offline. The default value (0) allows an infinite number of failures if minTimeToWait is less than 0. If the minTimeToWait is not less than 0, afterFailures behaves as if the value is negative. A negative value for this parameter indicates that the site is taken offline after the time specified by minTimeToWait elapses.
The minTimeToWait parameter specifies the number (in milliseconds) to wait to mark an unresponsive site as offline. The site is taken offline after the number attempts specified in the afterFailures parameter conclude and the time specified by minTimeToWait after the first failure has elapsed. If this parameter is set to a value smaller than or equal to 0, this parameter is disregarded and the site is taken offline based solely on the afterFailures parameter.
