Reason:
---------

The APPLPTEMP location points to a directory which is not in the utl_file directory in the database. So when the application user is trying to create a temp file in the location it is not allowed.


grep -i APPLPTMP $CONTEXT_FILE
         /doyen/app/DOYENSYS/fs2/inst/apps/DOYENSYS_sara1/temp


when i check the utl_file, It shows the following :

/usr/tmp


 Solution:
=======

1. Either add the following location in utl_file dir and restart the db /doyen/app/DOYENSYS/fs2/inst/apps/DOYENSYS_sara1/temp    or
2. Change the s_applptmp value to /usr/tmp and run autoconfig and try running the report again.
