Primary Server Configuration

These steps must be performed on the XDB Server that will be performing outbound mapping. In the examples, the XDB Server develop is performing outbound mapping.

To update the system tables:

Note: When updating system tables, do not delete any seemingly empty records; these contain space characters in some columns and refer to locations controlled by your local XDB Server.

On any client logged in to the primary XDB Server, start SQL Wizard.
Log in with an AuthID that has super user privileges, such as the INSTALL AuthID, provided with the XDB Server.
From an SQL Window, set the current location to the system location:
```
SET LOCATION TO system;
```

Issue the following SQL command to update information in the SYSIBM.SYSLUNAMES table about server-to-server connectivity and outbound mapping.

UPDATE sysibm.syslunames SET username = "O" 
    WHERE luname = "remote-server";

where:

`O`	indicates that requests going to the remote XDB Server will be subject to outbound mapping.
`remote-server`	is the name of a remote XDB Server for which AuthIDs will be mapped.

Other columns in the SYSIBM.SYSLUNAMES table are used for trusting servers. See the section Trusting for more information on using these values.

In the examples on outbound mapping used in this topic, the SQL command:

UPDATE sysibm.syslunames SET username = "O" 
    WHERE luname = "sales";

would have been issued on the XDB Server develop.

Issue the following SQL command to insert information into the SYSIBM.SYSUSERNAMES table about AuthIDs that will be subject to outbound mapping.
```
INSERT INTO SYSIBM.SYSUSERNAMES 
    VALUES("O","authid","servername", 
           "
```
