Troubleshooting
Troubleshooting networked applications is often difficult. Key information for SPD Server
troubleshooting can be found in the Name Server and SPD Server host process log files.
With those two log files, you can reconstruct SAS interaction with SPD Server components.
Entries in these log files are time-stamped for reference. You should be able to correlate
activities between the two logs by using the time-stamp information. The logs are formatted
as plain text files.
Name Server Start-Up Failed
Check the Name Server log file. The log should contain information about the problem.
Some common things to look for include:
1. Invalid -LICENSEFILE file specification.
2. -LICENSEFILE specifies a file with invalid contents.
3. The Name Server port is in use by another process. Check for another Name Server
process running already on the same node.
ps -ef | grep -i spdsnsrv
SPD Server Host Start-Up Failed
Check the SPD Server host log file for information. Some common things to look for
include:
1. -NAMESERVER node name is incorrect.
2. -NAMESERVERPORT specifies the wrong port number if the SPD Server Name
Server is running with a non-standard port assignment.
3. -PARMFILE file specification is invalid, or the specified file does not exist.
4. -LIBNAMEFILE file specification is invalid, or the specified file does not exist.
5. The contents of the specified -LIBNAMEFILE does not conform to expected syntax.
Check the SPD Server host log file for messages about invalid entries.
6. The -ACLDIR option was omitted from the command line.
7. The -ACLDIR option specifies an invalid directory path for the SPD Server password
file, or the specified directory path does not contain a valid SPD Server password file.
SAS LIBNAME Assignment Failed
On the SAS side, first attempts to diagnose a failure depend on the error messages from
the SPD Server LIBNAME engine through the SAS LOG output. In most circumstances
you should be able to diagnose the reason for the failure from this message. Some common
problems include:
1. Invalid specification of the LIBNAME engine selector in the LIBNAME statement.
The SPD Server engine name is sasspds and is misspelled in the following LIBNAME
statement.
