Hello, I’m a senior software engineer and I’m happy to help answer your question about the Cluster Time Synchronization Service (CTSS).
CTSS is an essential component of Oracle Clusterware which helps detect time synchronization issues between nodes in a cluster. It’s worth noting that CTSS is installed as part of Oracle Clusterware, so it’s readily available for use.
If there are any time synchronization services or configurations detected on the system, CTSS will run in observer mode. For instance, if the etc/ntp.conf file exists on any node within the cluster, even if no time synchronization software is running, CTSS will still run in observer mode.
The great thing about CTSS is its ability to identify any potential time synchronization problems across multiple nodes within a cluster. This helps ensure all systems are synchronized and functioning properly.
I hope this information helps! Let me know if you have any further questions.
