SAS/SHARE Server Tasks

Each server must be defined as a service in the TCP/IP SERVICES file on each node that a client will connect to. This file usually is located in the directory that the TCP/IP software is installed in. For details about editing the SERVICES file, see Configuring the SERVICES File.

Example:

sassrv2   5011/tcp  # 
SAS/SHARE server 2

To authenticate connecting clients, you must specify the value _SECURE_ in the TCPSEC= option to require that clients provide a user ID and a password that are valid on the server. For details about the TCPSEC= option, see SAS/SHARE Options Only .

If network security is configured at the server, you can specify SAS options to encrypt data that a server transfers to a client. For example:

options netencrypt netencryptalgorithm=rc4;

The NETENCRYPT option specifies that all data transfers between a server and a client will be encrypted. The RC4 security algorithm is assigned in the NETENCRYPTALGORITHM= option. For details about encryption services, see Encryption in SAS, located in the Base SAS Help and Documentation.

You must specify TCP/IP as the communications access method at the server before a client can access it. You can use the COMAMID= option in an OPTIONS statement. For example:

options comamid=tcp;

The COMAMID= option specifies the communications access method. TCP specifies the TCP/IP access method.

Alternatively, you can specify the COMAMID= option in a SAS start-up command or in a SAS configuration file.

The COMAUX1= option specifies an auxiliary communications access method and can be specified only in a SAS start-up command or in a SAS configuration file.

Here is the syntax for the COMAUX1= option:

COMAUX1=alternate-method

If the first method fails to access a server, the second method is used. You can specify one auxiliary access method.

Example:

comamid=tcp
comaux1=xms

You must specify the name of the server in the SERVER= option in the PROC SERVER statement.

SERVER=server

server can be either a server-ID or a port number. The server-ID corresponds to the service that was configured in the SERVICES file. For details, see Configuring the Server Service . The value for port is the unique number that is associated with the service that is used for transferring data between a client and a server. Precede the port number with two consecutive underscores.

Examples:

proc server server=apex;
proc server server=_ _5000;

For details about creating valid SAS names, see SAS Language Reference: Concepts. For details about PROC SERVER, see The SERVER Procedure in SAS/SHARE User's Guide.

The following example shows the statements that you specify in the server configuration file on a computer that runs the z/OS operating environment:

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

The value _SECURE_ that is specified for the TCPSEC option requires clients to provide a user ID and a password that are valid on the server.

The COMAMID= option specifies the TCP/IP access method. The PROC SERVER statement specifies the server SHARE1.
