Setting up the connection configuration parameters

When Mirror Replication Agent connects to another Mirror Activator for Oracle system component, it uses values stored in its configuration parameters to define the following minimal set of connection properties:

Server host name
Port number
User login name
User login password

For its connection to the Replication Server, Mirror Replication Agent relies on the values of two additional configuration parameters (rs_source_db and rs_source_ds) to identify the Replication Server primary database connection in the LTL connect source command.

The Mirror Replication Agent instance must be in Admin state to set up connection parameters. When the Mirror Replication Agent instance is Admin state, the instance has no connections established to other replication system components, but is available to execute administrative commands. For more information, see “Understanding Mirror Replication Agent states”.

The values of the rs_source_db and rs_source_ds parameters must exactly match the database and data server names specified in the create connection command for the Replication Server primary database connection. The values are case sensitive.

For more information about the rs_source_db and rs_source_ds parameters, see the Mirror Activator for Oracle Mirror Replication Agent Reference Manual.

You can use the “Installation and Setup Worksheet,” in the Mirror Activator for Oracle Installation Guide, to record the values of connection configuration parameters for each Mirror Replication Agent instance.

Refer to the “Installation and Setup Worksheet” for the connection configuration parameter values you need to set in the following procedures.

The Mirror Replication Agent instance must be running before you can set its connection configuration parameter values. See “Starting the Mirror Replication Agent” for more information.

To set up connection parameters for the primary database

When the Mirror Replication Agent instance is Admin state, the instance has no connections established to other replication system components, but is available to execute administrative commands. The Mirror Replication Agent instance must be in Admin state to setup connection parameters.

Log in to the Mirror Replication Agent administration port, and verify that the Mirror Replication Agent instance is in Admin state.
1. Use the following command to verify that the Mirror Replication Agent instance is in Admin state:
```
ra_status
```
2. If the instance is not in Admin state, use the following command to put it in Admin state:
```
suspend
```
Specify the primary data server host name:
```
ra_config pds_hostname, pds_host
```
where pds_host is the network name of the primary data server host machine.
Specify the primary data server port number:
```
ra_config pds_port_number, NNN
```
where NNN is the number of the network port where the primary data server listens for connections.
Specify the primary database name:
```
ra_config pds_database_name, pdb
```
where pdb is the Oracle SID.
Specify the primary data server user login name for the Mirror Replication Agent instance:
```
ra_config pds_username, mro_pds_user
```
where mro_pds_user is the user login name that the Mirror Replication Agent uses to log in to the primary data server.
Specify the password for the Mirror Replication Agent user login:
```
ra_config pds_password, mro_pds_pwd
```
where mro_pds_pwd is the password for the user login name that the Mirror Replication Agent uses to log in to the primary data server.

After you set up connection configuration parameters for the primary database, you can use the Mirror Replication Agent test_connection PDS command to test connectivity between the Mirror Replication Agent and the primary database. See “Testing network connectivity” for more information.

To set up connection parameters for the Replication Server

Log in to the Mirror Replication Agent administration port, and verify that the Mirror Replication Agent instance is in Admin state:
1. Use the following command to verify that the Mirror Replication Agent instance is in Admin state:
```
ra_status
```
2. If the instance is not in Admin state, use the following command to put it in Admin state:
```
suspend
```
Specify the Replication Server host name:
```
ra_config rs_hostname, rs_host
```
where rs_host is the network name of the Replication Server host machine.
Specify the Replication Server port number:
```
ra_config rs_port_number, NNN
```
where NNN is the number of the network port where Replication Server listens for connections.
Specify the Replication Server character set:
```
rs_charset
```
where rs_charset matches the character set used by Replication Server. If rs_charset is not set, Mirror Replication Agent refuses to replicate anything.
Specify the Replication Server user login name for the Mirror Replication Agent instance:
```
ra_config rs_username, mro_rs_user
```
where mro_rs_user is the user login name that the Mirror Replication Agent uses to log in to the Replication Server.
Specify the user login password for the Mirror Replication Agent instance:
```
ra_config rs_password, mro_rs_pwd
```
where mro_rs_pwd is the password for the user login name that the Mirror Replication Agent uses to log in to the Replication Server.
Specify the primary data server name for the Replication Server primary database connection:
```
ra_config rs_source_ds, pds
```
where pds is the primary data server name that the Mirror Replication Agent uses in the LTL connect source command.
Specify the primary database name for the Replication Server primary database connection:
```
ra_config rs_source_db, pdb
```
where pdb is the primary database name that the Mirror Replication Agent uses in the LTL connect source command.

To set up connection parameters for the ERSSD (or RSSD)

Log in to the Mirror Replication Agent administration port, and verify that the Mirror Replication Agent instance is in Admin state:
1. Use the following command to verify that the Mirror Replication Agent instance is in Admin state:
```
ra_status
```
2. If the instance is not in Admin state, use the following command to put it in Admin state:
```
suspend
```
Specify the ERSSD host name:
```
ra_config rssd_hostname, rssd_host
```
where erssd_host is the network name of the ERSSD host machine.
Specify the ERSSD port number:
```
ra_config rssd_port_number, NNN
```
where NNN is the number of the network port where the ERSSD server listens for connections.
Specify the ERSSD database name:
```
ra_config rssd_database_name, rssd_db
```
where rssd_db is the database name of the ERSSD.
Specify the ERSSD user login name for the Mirror Replication Agent instance:
```
ra_config rssd_username, mro_rssd_user
```
where mro_erssd_user is the user login name that the Mirror Replication Agent uses to log in to the ERSSD.
Specify the user login password for the Mirror Replication Agent instance:
```
ra_config rssd_password, mro_rssd_pwd
```
where mro_rssd_pwd is the password for the user login name that the Mirror Replication Agent uses to log in to the RSSD.

After you set up connection configuration parameters for the Replication Server and RSSD, you can use the Mirror Replication Agent test_connection RS command to test connectivity between the Mirror Replication Agent and the Replication Server and RSSD. For more information, see “Testing network connectivity”.
