Extended Settings for clustered polling notifications

Hi

We have installed SP1 on IS6.1 so as to enable clustering on JDBC polling notifications

When I look in extended settings, I only have the following settings:

watt.art.clusteredPollingNotification.repoFailureRetryCount=5
watt.art.clusteredPollingNotification.repoFailureRetryInterval=140000

Are these settings equivalent to the

watt.art.clusteredPollingNotification.keepAliveInterval
watt.art.clusteredPollingNotification.keepAliveExpireTimeout

settings specified in the documentation?

If not, then what do these settings represent and how do I get the PollingNotification settings ?

Thanks for any help
