Communications Access Methods for SAS/CONNECT and SAS/SHARE Software

CMS: TCP/IP Access Method

SAS/CONNECT

Local Host

The following example illustrates the statements that you specify in a CMS local host SAS session to connect to a remote host with the TCP/IP access method.

These commands save the script-file in the local host's environment. The fileref format follows:

filename rlink 'sasconne maclib';

The following commands are issued from the command line in the PROGRAM EDITOR window:

inc rlink(tcpunix)
file 'tcpunix'

The following statements are issued in the CMS local host SAS session:

filename rlink 'tcpunix' a;
options comamid=tcp remote=rmthost.unxspawn;
signon user=_prompt_;

The first line identifies the script file that you use to sign on to the UNIX remote host by means of the UNIX spawner program. The script file contains a prompt for a userid and a password that are valid at the remote host. The TCP/IP communications access method is declared with a connection to a remote UNIX spawner that is identified by the two-level name RMTHOST.UNXSPAWN. The SIGNON statement performs the sign-on process. The USER= option in the SIGNON statement specifies that the connecting local host be prompted for a userid and a password that are valid on the remote host.

Remote Host

You do not perform any tasks at the CMS remote host for the TCP/IP access method.

SAS/SHARE

Client

The following example illustrates the statements that you specify in a CMS client SAS session to access a server with the TCP/IP access method:

options comamid=tcp;
libname sasdata 'sasdata a' server=rmtnode.share1 user=_prompt_ ;

The TCP/IP access method is declared. The LIBNAME statement specifies the data library that is accessed through the server that is identified by the two-level name RMTNODE.SHARE1. The USER= option in the LIBNAME statement specifies that a client be prompted for a userid and a password that are valid on the server.

Server

The following example illustrates the statements that you specify in a SAS session on the CMS host at which you start a server:

%let tcpsec=_secure_;
options comamid=tcp;
proc server id=share1;
run;

The _SECURE_ value for the TCPSEC macro variable requires clients to supply a valid server userid and password in order to allow client access to the server. The TCP/IP access method is declared and the server SHARE1 is started on the CMS host.
