The DSI thread of a Replication Server connection is where
the replicated transaction is delivered by Replication Server.
Every
replicate database expected to receive replicated transactions must
be represented by a Replication Server connection with an enabled
DSI thread.
Replication Server establishes a connection directly with the replicate database,
if it resides in Adaptive Server. If the replicate database resides in a non-SAP data server,
Replication Server communicates using:
-
An ECDA database gateway by way of the connection’s DSI thread, or,
-
ExpressConnect to establish a connection directly with the Oracle or SAP
HANA replicate database.
Note: A replicate data server or database gateway never attempts
to connect to the DSI thread of a connection. The only entity that
can initiate communication to a DSI thread is the Replication Server.
On a DSI thread, the Replication Server is the client, and
the replicate data server or database gateway is the server.
