When you create or modify a public SAS LASR Analytic Server in the SAS^® Visual Analytics Administrator and then start the SAS LASR Analytic Server, an error message might appear:

Starting the SAS LASR Analytic Server failed.

ERROR: Failed to create a LASR Analytic Server signature file. Make sure that 
the path is specified correctly and that you have write permission to that path.
ERROR: Failed to start a LASR Analytic Server on the local host.
ERROR: Libref ML is not assigned
ERROR: Error in the libname statement

To Resolve This Error

1. Click the SAS LASR Analytic Server definition Advanced Options button.
2. Click the Additional Options tab.
3. Review the Signature files location on server path. For Windows operating systems, this should be a relative Windows path.
4. If you are accessing an existing SAS LASR Analytic Server, ensure that the folders in this path exist and are not set to Read-only.
5. If you are creating an additional SAS LASR Analytic Server, change the path to a similar signature files folder used for the initial public SAS LASR Analytic Server, such as the following:

\6.2\VisualAnalyticsAdministrator\sigfiles2

6. For either the existing path or a newly created path, ensure that the permissions for folders in this path are as documented in the secure documentation SAS^® Visual Analytics 6.4 Administration Guide, Chapter 6: Security. For details about signature files locations and permissions, see Chapter 9: SAS LASR Analytic Server. For access to this secure documentation, contact SAS Technical Support and provide your SAS site number.
