Client Connection Using a Spawner

The spawner service can be configured in the client's SERVICES file, but this is not a requirement. The spawner can use a port number or have the port information (service or port) defined in metadata. You can explicitly specify the port on the command line and in the SIGNON statement. For information about configuring the SERVICES file, see Configuring the Services File.

If you use a script when connecting to a spawner, script file processing passes the user ID and password to the server. However, if you do not use a script file, you can deliver the user ID and password to the server by specifying values for the USERID= and PASSWORD= options in the SIGNON statement. Windows users can use SSPI if it is enabled. See SSPI for information about SSPI.

If you do not use a script file, use the following syntax to connect to the spawner:

options remote=spawner-ID;
signon user=user-ID password=password;

In the UNIX and Windows environments, the TCP/IP access method is used by default. The spawner connects the client to the spawner named SPAWN that runs on the UNIX node RMTHOST. If there is no script file, the user ID and password are specified as options in the SIGNON statement. The value _PROMPT_ for PASSWORD causes SAS to prompt for a password at sign-on. The SIGNON statement makes the connection and starts a SAS session on the server.
