Solution 2334755.1 : Does "hwclock -w" still need to be run periodically on DSR HP servers.

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 5.0 and later
Information in this document applies to any platform.

Goal

To Answer the following question:

When DSR had been initially deployed in some networks, it was determined that "hwclock -w" would need to executed periodically in order to keep the HP Gen6 hardware clock synchronized with the NTP sources.
Is it still necessary for this periodic synchronization to take place for DSR servers on HP hardware.

Solution

In this Document

This was due to a bug in earlier releases of the product (Bug ID19102428).
The fix for this bug did the following:
---------
Enable 11-minute mode so that ntpd will write the system clock to the
hardware clock every 11 minutes.
---------
This fix was applied in TPD 6.5.0-82.16.0.

DSR 5.0 is deployed with TPD 6.5.1-82.28.0. Hence for all DSR releases beyond 5.0 manual execution of hwclock -w is no longer necessary.
