SAS/SHARE Server Tasks

Each server must be defined as a service in the SERVICES file on each node that a client will access. The SERVICES file is located in the directory where the TCP/IP software is installed. 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 .

Example:

options tcpsec=_secure_;

If you use only SSPI for authentication, setting user rights is not necessary.

If you use the simulated logon method of authentication, the following user rights must be set at the server machine:

If an encryption service 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=ssl;

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

TCP/IP is the default communications access method on Windows. You can omit specifying the access method in the COMAMID= option, and the TCP/IP communications access method is assumed, by default. If you choose to specify TCP/IP to connect to a server, you can use the COMAMID= option in an OPTIONS statement.

options comamid=tcp;

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

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 value for server-ID corresponds to the service that was configured in the SERVICES file. For details, see Configuring the Services File. 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 SAS naming rules, see SAS Language Reference: Concepts. For details about the PROC SERVER statement, see the SAS/SHARE User's Guide.

The following example shows the statements that you specify in a SAS session at the machine where the server runs. The TCP/IP access method is specified and the server SHARE1 is started on the Windows machine.

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