CAUSE

 

This problem is due to the Bug 11837095 - "TIME DRIFT DETECTED" APPEARS INTERMITTENTLY IN ALERT LOG"

 

SOLUTION

1) Please set the next event on the ASM instances to remove the "Warning: VKTM detected a time drift" message:

 

SQL> alter system set event="10795 trace name context forever, level 2" scope=spfile;



2) Then bounce the ASM instances to implement the event/change.

 

Note 1: Bug 11837095 - is fixed on release 12c.
Note 2: This warning can be ignored since it harmless.
