-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:
Does not use two-phase commit.
(Default) Uses two-phase commit.
IMPORTANT!  The lack of two-phase commit increases the possibility of loss of data integrity in uncompleted transactions.
