GT.M Supplementary Instance Replication

Summary

Effective V5.5-000, FIS GT.M adds a new type of replication, called Supplementary Instance (SI) replication. The previous sole replication mechanism is now called Business Continuity (BC) replication in order to distinguish between them.

At the time of writing, V5.5-000 is the only GT.M release to support SI replication. Should later releases exist when you peruse this technical bulletin, please read “V5.5-000 or later, as clarified or qualified by the release notes for your release” for “V5.5-000” below.

In this document, unless more specifically designated, the term “transaction” refers to all TP transactions - updates within TSTART/TCOMMIT brackets (with nested transactions, the outermost one), and all so-called “mini transactions” - individual updates (Sets, Kills, and ZKills) not within TSTART/TCOMMIT brackets.
