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

IP Access Method

SAS/CONNECT

Local Host

The following example illustrates the statements that you specify in an OS/390 local host SAS session to connect to a remote host with the TCP/IP access method:

filename rlink 'sas.ctmisc.tcpvms';
options comamid=tcp remote=rmthost;
signon user=_prompt_;

The first line identifies the script file that you use to sign on to the OpenVMS remote host. The script file contains a prompt for a userid and a password that are valid on the remote host. The TCP/IP communications access method is declared with a connection to the remote host RMTHOST. The SIGNON statement performs the sign-on process. The USER= option in the SIGNON statement specifies that a local host be prompted for a username and a password that are valid on the remote host.

Remote Host

You may set the following variables to restrict port access in the SAS CLIST:

portfirst(5020)
portlast(5050)

These statements restrict access to ports 5020 through 5050.

SAS/SHARE

Client

The following example illustrates the statements that you specify in an OS/390 client SAS session to access a server with the TCP/IP access method:

options comamid=tcp;
libname sasdata 'edc.prog2.sasdata' server=rmtnode.share1 user=_prompt_;

The first line declares the TCP/IP access method. The LIBNAME statement specifies the data library that is accessed through the two-level server 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 the server's configuration file on the OS/390 host:

tcpsec=_secure_

The _SECURE_ value for the TCPSEC macro variable requires clients to supply a userid and a password that are valid on the server.

The following example illustrates the statements that you specify in a SAS session on the OS/390 host at which you start a server:

options comamid=tcp;
proc server id=share1;
run;

The TCP/IP access method is declared and the server SHARE1 is started on the OS/390 host.
