NTP(Network Time Protocol) Error whil installing Oracle 11gR2 RAC
Dear Friends,
I have installed oracle 11gr2 clusterware software in two node RAC. While i run the CLUVFY.SH, It shows error in NTP configuration.
1)I add "-x" parameter in "/etc/sysconfig/ntp" configuration file. and start the ntpd service and run the cluvfy.sh . then i got the below error.
Check: CTSS state

rac2 Observer

2)Down the ntpd service in both nodes and run the CLUVFY.SH.

3)Based on some website advice, I down the ntpd service and move the "/etc/ntpd.conf" to another location.Then i got the below error.
Result: Query of CTSS for time offset passed

What should i do to solve this issue?? Please help me ...
