Time Sync Configuration for OCSM in Oracle Linux (Doc ID 2251096.1)

Last updated on MAY 02, 2017

Applies to:

Oracle Communications Session Monitor - Version 3.4.x and later
Information in this document applies to any platform.

Symptoms

It is important for ALL OCSM nodes (MECs, MEs, Probes) to be in sync, as the call data is heavily based in the timestamp each packet (SIP, RTP, etc.) is marked with. A time difference between ME and Probe may cause packets to get dropped and never get evaluated, RTP packets to not get accounted for in voice quality statistics evaluation, and voice quality Screen being empty, among others. 

Changes

Note that in OCSM 3.3.9x releases, Date and Time configuration was part of PSA. In OCSM 3.4.x, this is part of the Operating System configuration, and not OCSM application.
