(1).  OS NTP vs Oracle GI ctssd (Cluster Synchronization Service Daemon) OS 有設NTP , 則 GI ctssd 以 observer  模式啟動 OS 沒設 NTP,  , 則 GI ctssd 以 active  模式啟動 參考 https://community.toadworld.com/platforms/oracle/b/weblog/archive/2015/03/12/switching-ctssd-from-active-mode-to-observer-mode (2). 設定 NTP 微調式 (slew)修正時間 依 metalink Doc ID 1056693.1 , 在 Solaris 上的設定方式如下: Solaris 10: #  egrep 'slewalways|pll' /etc/inet/ntp.conf slewalways yes disable pll To set, modify the configuration file. Solaris 11: # svcprop -p config/slew_always svc:/network/ntp:default true To set: # svccfg -s svc:/network/ntp:default setprop config/slew_always = true 設定完成後, 以 下列兩個指令生效 (單純 stop/start 不會生效) # /usr/sbin/svcadm refresh ntp # /usr/sbin/svcadm restart ntp (3) 關於 NTP 微調式修正時間 文件同時提到, NTP 需以微調方式修正系統時間, 否則會出珼下列錯誤 但是在 Oracle 12c GI 上 沒出現此問題 $GRID_HOME/bin/cluvfy comp clocksync -n all ..
