Setting SAS Options and Variables |
You may need to set specific options in SAS to allow the connections that you want with SAS/CONNECT and SAS/SHARE when using the SPX communications access method.
Consult with your network administrator for advice about these settings.
You may specify an option in several forms, as follows:
OPTIONS SET=variable-name value;
Example:
options set=spxmsgsize 1514;
-set variable-name value
Example:
-set spxmsgsize 1514
SET variable-name=value
Example:
SET spxmsgsize=1514
Values for these options may contain up to eight characters, consisting of alphanumeric characters, the percent sign (%), the dollar sign ($), the pound sign (#), the at sign (@), and the underscore (_).
If you set multiple forms of the same option , here is the order of precedence that is followed:
OPTIONS statement | |
AUTOEXEC file | |
SAS invocation | |
SAS configuration file | |
DOS environment variable. |
SAS/CONNECT and SAS/SHARE SPXMSGSIZE Option |
Be aware that your selection should not violate the buffer size limitations of the Novell Requestor. The OS/2 requestor defaults to a buffer size of 1514 bytes, and the SPX access method also defaults to a buffer size of 1514 bytes. Because the size of the buffer is limited to 576 bytes when using a bridge, if you use SPX over a bridge, you must explicitly define a 576 buffer size for SPX and the Novell Requestor. You set the buffer size for SAS software and the Novell Requestor as follows:
link support buffers 30 576
The number 30 refers to the number of buffers; the number 576 refers to the size of each buffer, in bytes. The product of these numbers cannot exceed 64K bytes (1,024 bytes = 1K byte).
The maximum buffer size for Ethernet is 1514 bytes, and the maximum buffer size for Token Ring is 4202 bytes. If you are using a Token Ring network, you may want to change the BUFFERS statement in your NET.CFG file to a 4202-byte buffer size and set the SPXMSGSIZE option to 4202.
Ask your network administrator for advice about setting this option.
