-TPC Flag--Control Use of Two-phase Commit

Ingres Replicator cannot propagate replications in an cluster environment in the same way that it does in noncluster environments. By default, Replicator Server uses two-phase commit, which is not supported at sites running Ingres Cluster Solution.

Replicator Server has a flag, -TPC, that allows all installations (including Ingres Cluster Solution) to control whether Replicator Server uses two-phase commit.

The -TPC flag can have the following values:

-TPC0

Does not use two-phase commit.

-TPC1

(Default) Uses two phase commit.

IMPORTANT! The lack of two-phase commit increases the possibility of loss of data integrity in uncompleted transactions.
