Sybase DC38133-01-0902-01 manual Set up the remote database, To create the publication

❖To create the publication

1.Connect to the database from Interactive SQL, and execute the following statement:

CREATE PUBLICATION SalesRepData ( TABLE SalesRep,

TABLE Customer SUBSCRIBE BY rep_key

)

Set up a subscription Each user ID that is to receive changes to the publication must have a subscription. The subscription can only be created for a user who has REMOTE permissions. The GRANT REMOTE statement contains the address to use when sending the messages.

❖To create the subscription

1.Connect to the database from Interactive SQL, and execute the following statement:

CREATE SUBSCRIPTION

TO SalesRepData (’rep1’)

FOR field_user ;

The value rep1 is the rep_key value we will give to the user field_user in the SalesRep table.

The full CREATE SUBSCRIPTION statement allows control over the data in subscriptions; allowing users to receive only some of the rows in the publication. For more information, see “CREATE SUBSCRIPTION statement” on page 358 .

The CREATE SUBSCRIPTION statement identifies the subscriber and defines what they receive. However, it does not synchronize data, or start the sending of messages.

Set up the remote database

The remote database needs to be configured in order to send and receive messages and participate in a SQL Remote setup. Like the consolidated database, the remote database needs a CURRENT PUBLISHER to identify the source of outgoing messages, and it needs to have the consolidated database identified as a subscriber. The remote database also needs the publication to be created and needs a subscription created for the consolidated database. The remote database also needs to be synchronized with the consolidated database; that is, it needs to have a current copy of the data in order for the replication to start.
