When using the Teradata FastExport to increase the read performance of a Teradata table, the following error might occur:

   Error: FastExport either failed before connecting to SAS or timed out before invoking the access module.

This error can occur if too many concurrent utility sessions are 
occurring on the server.

It can also mean that the FastExport module or utility cannot be found.

Another cause for the error is FastExport is having trouble creating the 
log tables on the Teradata database. This can occur because there are 
insufficient permissions or space constraints.  

To correct this error, the LOGDB LIBNAME option can be used to redirect
the FastExport logs to an alternate database, as in the following example: 

   libname mydblib teradata user=testuser pw=testpass logdb=altdb;
   proc print data=mydblib.mytable(dbsliceparm=all);
   run;
