Hello guru of oracle-l
how do you plan pass leap seond on lujy 30 of 2015 ?
it is enough to have latest ntp package ? or we need also latest kernel?
what do i found :
а) database side Leap seconds (extra second in a year) and impact on the
Oracle database. (Doc ID 730795.1)
<https://support.oracle.com/epmos/faces/ui/km/DocumentDisplay.jspx?id=730795.1>
..
Oracle RDBMS uses "Unix time", it has no clock of it's own and simply
uses the OS to deliver the current time and date.
....
Please work with your systems admin that, if your OS is updated to know
about the leap second, to *configure it in such a way it does not report
60 seconds as a OS time when a leap second is added.**
*
b) os side:
as per RH note Resolve Leap Second Issues in Red Hat Enterprise Linux
<https://access.redhat.com/articles/15145>
with latest version of ntp client leap second will be added by passing 2
times 59 second and no 60 second will occur
