Solution 2360620.1 : SBR Replication Time

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 5.1 to DSR 7.3.0 [Release DSR 5.0 to DSR 7.0]
Tekelec

Goal

During Switch over from Active to Standby Normal replication may take some time based on the size of the database, also the amount of time it takes to resynchronize the database depends on many variables. What is an estimated time for this replication?

Solution

Time for replication = Network Speed x (Data size + Overhead)

where,

Overhead = Packet size + Acknowledgement + latency + Data translation time

The flow is like this:

Data Transfer >> Data Translation >> Data Write in memory

Translation consists of reading each record, translating it, and then writing it.

A first write is to temporary memory and when translation is complete then an additional write per record is required to write it to it final memory locations.

Data Translations is required between mixed releases.

Note: One session equals one record.

Please note that newer releases (e.g. 7.3.1 in this case) improved the resiliency of bulk downloads in faulty networks.
