Advanced configuration 295 Establishing high availability failover 6 In Apply Changes To, select the node or subset of nodes that you want to apply the parameter to. 7 Click OK to save the changes to this sensor and close. Caution: Make sure that the system has enough RAM for this parameter. Setting Watchdog Process Stop Window Watchdog Process Stop Window determines the time period during which Symantec Network Security decides if failures occur at too high a rate. If a node fails too many times during this time period, then it shuts down and fails over to the standby node. The default value is 10 minutes. To configure node parameters 1 Click Configuration > Node > Network Security Parameters. 2 In Select Node, choose the node from the pull-down list, and click OK. 3 In the left pane, click the parameter that you want to configure. 4 In the lower right corner of the Configuration Parameters pane, enter a fail rate. If the number of failures breaches this threshold, it resorts to standby. 5 Click Apply. 6 In Apply Changes To, select the node or subset of nodes that you want to apply the parameter to. 7 Click OK to save the changes to this sensor and close. Caution: Make sure that the system has enough RAM for this parameter. Before setting this parameter, please review the failover procedure thoroughly. Setting Watchdog Process Maximum Resets Watchdog Process Maximum Resets defines the maximum number of reboots or restarts that Symantec Network Security executes within the time period defined by Watchdog Process Stop Window before failing over to the standby node. The default value is 2. To configure node parameters 1 Click Configuration > Node > Network Security Parameters. 2 In Select Node, choose the node from the pull-down list, and click OK.
