Problem:
On OS the time is showing 16:00 while the Clusterware and DB logs time are showing 20:00
OS Time
Cluster's Log Time:
Analysis:
The configured timezone in the cluster environment config file was different from the OS timezone:
OS Timezone: is UTC
# cat /etc/sysconfig/clock
Cluster Timezone: is Dubai
# cat $GRID_HOME/crs/install/s_crsconfig_nodex1_env.txt
Solution:
change the Cluster timzone to be similar to OS timezone:
# vi $GRID_HOME/crs/install/s_crsconfig_nodex1_env.txt
Note: The clusterware and DB logs will pick the new timezone once you restart the clusterware.
