Setup Verification
Creating a Messaging Gateway Administration User
To perform gateway administration work, a database user with MGW_
ADMINISTRATOR_ROLE privileges must be created.
Creating an Administration User: Example
CREATE USER IDENTIFED BY ;
GRANT CONNECT, RESOURCE to ;
GRANT MGW_ADMINISTRATOR_ROLE to ;
Setting Up Messaging Gateway
Creating a Messaging Gateway Agent User
To establish the gateway agent’s connection back to the database, a database user
with MGW_AGENT_ROLE privileges must be created.
Creating an Agent User: Example
CREATE USER IDENTIFED BY ;
GRANT CONNECT, RESOURCE to ;
GRANT MGW_AGENT_ROLE to ;
Configuring Messaging Gateway Connection Information
After the agent user is created, the administration user uses DBMS_MGWADM.DB_
CONNECT_INFO to configure Messaging Gateway with the user name, password,
and database connect string used by the gateway agent to connect back to database.
Use the agent user name and password that are created in "Creating an Agent User:
Example" on page 18-11. The database connect string parameter can be set to either
a new service name in tnsnames.ora (with IPC protocol for better performance)
or null. If null, the oracle_sid parameter must be set in mgw.ora.
For release 9.2, always specify a nonnull value for the database connect string
parameter when calling DBMS_MGW_DB_CONNECT_INFO( ).
Using DBMS_MGWADM.DB_CONNECT_INFO: Example
connect /
exec dbms_mgwadm.db_connect_info('','', '');
The following procedure verifies the installation and includes a simple startup and
shutdown of the Messaging Gateway agent.
