Replication Server and

SQL Remote allows two-way replication between the consolidated database

SQL Remote

and remote databases. Replication Server is performing one-way replication

 

from the consolidated database to the SQL Remote Open Server. From

 

Replication Server’s perspective, transactions that originate in remote

 

SQL Remote databases appear as transactions originating in the consolidated

 

SQL Remote database.

SQL Remote system

The SQL Remote Open Server requires information from the SQL Remote

tables

system tables concerning publications and subscriptions. The Open Server

 

uses a connection to the Adaptive Server Enterprise database holding that

 

information to retrieve it when it starts.

 

If the SQL Remote system tables are updated while the Open Server is

 

running, the SQL Remote Open Server needs to receive this information at

 

the correct time. For this reason, some of the SQL Remote system tables

 

need to be marked for replication. This is described in “Setting up SQL

 

Remote Open Server” on page 282 .

The SQL Remote Open

The SQL Remote Open Server is the following executable:

Server executable

On Windows operating systems, the SQL Remote Open Server is
