SQL Remote User's Guide
  Using SQL Remote with Replication Server
    Configuring Replication Server

Set the dsi_xact_group_size parameter

By default, Replication Server groups multiple transactions into larger transactions. The dsi_xact_group_size parameter controls the maximum size of a grouped transaction.

The dsi_xact_group_size parameter must be set to -1 to disable transaction grouping. Transactions that originate from different remote databases in a SQL Remote setup must not be grouped together.

How to set the parameter 

You can set the parameter using the following statement:

CONFIGURE CONNECTION TO  "ssqueue_server"
SET dsi_xact_group_size TO '-1'
