We're running 11g clusterware on RHEL Linux. Which NTP is recommended by Oracle? NTP or CTSSD?
By default, if a time sync software (NTP) is running, ctssd will run in observer mode. What is the recommended or best practice? It seems odd that only the RAC clusters are seeing time drift issues and I’m wondering if it is because we have both NTP and CTSSD running even if CTSSD is in Observer Mode. Through my research, I’m not clear as to what is recommended. Seen mixed messages.
