I got the below error message on non-clustered node running AIX 5.3 TL 12 after i run ntpdate:
"37F3CC40 P U RMCdaemon RSCT has detected that system time has moved backward"

My question is will this have effect on the non-clustered server? If there is, what is the solution?

    I believe it would affect your apps more than your OS. If your apps are transaction based or a DB then I would think that you need to research what's affected with the vendor. I work for a hospital so changing the time can be bad when it comes to patient data, labs, Radiology results, patient charges...etc. Believe me it's not fun when it happens on a critical system and users are forced to go check their data.
    Do you not have the ntpd daemon running at all times? It's not a requirement but I recommend it so you don't have to worry about the time getting off track. I would recommend using the Navy's ntp servers or some other reliable NTP server.

    I even have this monitored to make sure it's up & running. I'm just paranoid since our incident last year.
    Good luck.

    If you have a transaction based applicaton then yes it will affect the data. But you should be running xntpd anyway.

    We are a hospital so time keeping is very important because we see patients and process millions of transactions daily  which are time based.

    As I stated before check your xntpd daemon.  Is is running?  Do you have it configured? 

    There are many documents that you can find on the internet that will explain how to configure it.

    If your site doesn't have it's own ntp (time server) server then configure your AIX to use the government's time servers.  I use the US Navy's time servers.

     

    Good Luck.

    Make sure you have xntpd in slewing mode, not stepping. The clock changing abruptly is a symptom of stepping. In /etc/ntp.conf add "slewalways yes".
