RE: Question on 11gR2 RAC Cluster Time Synchronization Service (CTSS)

CTTS will indeed only keep the time of the cluster nodes synchronised between the nodes themselves and not with an external source. If you want this, then you need to configure the network time protocol (NTP) daemon. When the NTPD is running, the CTTS process will automatically run in "observer" mode.

Subject: Question on 11gR2 RAC Cluster Time Synchronization Service (CTSS)

Hi, List,

In a 11.2.0.2 RAC, with 11gR2 RAC Cluster Time Synchronization Service (CTSS) running in active mode, CTSS does its work to sync time among all nodes in the cluster. However, the time on all nodes gets behind after a while (say 5 minutes behind after 8 months) . How would you guys handle this situation? and how would you prevent this from happening again? I've googled and searched on oracle documentation and couldn't find anything about it.

Thanks in advance!
-Li
