|Communications Access Methods for SAS/CONNECT and SAS/SHARE Software|
Various errors may occur when you initially try to establish a connection over a network with the Sequenced Packet Exchange (SPX) access method. Many of these problems are related to the network. The following messages are a few of the more common errors you may encounter:
ERROR: Network partner xxxx not found.
The network name that you specified as the value for the REMOTE= option is invalid. The partner application is not running, is on a different network, or is using a different packet type. Ask your system administrator for valid names at your site.
ERROR: Communication request rejected by partner: security verification failure
Permission to access the remote host was denied. Verify that you specified both a valid userid and password for the remote system.
ERROR: Supporting access method initialization failure.
There is a configuration problem. Contact your systems personnel.
ERROR: Target application partner could not be located.
The remote SAS session could not be started by the spawner program. There is a configuration problem.
ERROR: File not found loading \sas\core\sasexe\sasvnspx.dll; File contributing to error: SPXCALLS
The SPX access method was loaded but the supporting SPX software was not found. Make sure that the directory that contains the SPXCALLS.DLL file is in the LIBPATH. (This message applies only to the OS/2 environment.)
ERROR: File not found loading \sas\core\sasexe\sasvnspx.dll; File contributing to error: IPXCALLS
The SPX access method was loaded but the supporting IPX software was not found. Make sure that the directory that contains the IPXCALLS.DLL file is in the LIBPATH.
Besides network errors, you should also be aware of operating system-dependent
considerations, which are described in the next two sections. If you cannot
resolve a problem based on the information provided in the error message and
this document, contact SAS Technical Support for assistance.
For the SPX access method to work properly, it must be configured so that it does 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 using SPX over a bridge, you must explicitly define a 576 buffer size for SPX and the Novell Requestor.
buffersstatement under the link support attribute in the
net.cfgfile. For example:
link support buffers 30 576
In this statement,
30 is the number
of buffers and
576 is the size of the buffers.
The product of these numbers cannot exceed 64K.
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
net.cfg to use 4202 byte buffers and set SPXMSGSIZE to 4202.
SAS/SHARE users and administrators can use the Novell Sequenced Packet Exchange (SPX) access method to communicate with a server that is running on the OS/2, the Windows NT, or the Windows 95 platform on the same network. You must have at least version 2.10 of the Novell Netware Requestor for OS/2. Specify SPX as the value for the COMAMID=, the COMAUX1=, or the COMAUX2= system option.
The SPX access method used by SAS/SHARE sometimes issues generalized messages to identify problems. Some of the most frequently encountered messages are described in this section.
Supporting access method initialization failure
There is a configuration problem. The Netware Requestor is not installed, or it is not installed properly. Contact your system administrator.
Network name server-id already in use
The server that is specified by the SERVERID= option is already being used by another application on your network.
Network partner server-id not found
The server that is specified in the SERVERID= option was not found. The server was not started, or it is on a different network, or it is using a different packet type.
