create logical connectionLocate this document in the navigation structure

Creates a logical connection. Replication Server uses logical connections to manage warm standby applications.

create logical connection to <data_server>.<database>
[set <logical_database_param> [to] ‘<value>’
[set <logical_database_param> [to] ‘<value>’]...]

The name of a data server. The data server does not have to be a real data server.


The name of a database. The database does not have to be a real database.


The name of the configuration parameter that affects logical connections. Configuration parameters affecting logical connections describes the parameters that you can set with create logical connection.

Example 1

Creates a logical connection called <LDS.logical_pubs2>:

create logical connection to LDS.logical_pubs2
Example 2

Creates a logical connection for an existing connection. For example, you would enter this if the database <TOKYO_DS.pubs2> already exists and will serve as the active database in the warm standby application:

create logical connection to TOKYO_DS.pubs2
  • create logical connection creates a logical connection to be used with warm standby applications. See the Replication Server Administration Guide Volume 2 for information about setting up and managing warm standby applications.

  • The logical connection is for a symbolic <data_server>.<database> specification. The data server and database do not have to be real; Replication Server maps them to the current active database.

  • If you are creating a logical connection for an existing connection, <data_server>.<database> must refer to the data server and database names of the existing connection. Otherwise, it is recommended that the logical name be different from the active and standby database names.

  • Replication definitions and subscriptions use the logical connection name.

  • After you create the logical connection, use rs_init to add the physical active and standby databases for the logical connection.


create logical connection requires “sa” permission.
