Thesaurus loading + DRG-11510: encountered unrecoverable error on line 1

Question

Hi All
I want to load thesarus present in the oracle home directory, so from command prompt i gave 'ctxload' command and gave the required inputs as shown below.
cmd prompt
D:\Documents and Settings\Administrator>ctxload
Enter user: ctxsys/ctxsys@mind2
Enter name: default
Enter file: E:\app\Administrator\product\11.1.0\db_1\ctx\sample\thes\dr0thsus.txt
Connecting...
DRG-11510: encountered unrecoverable error on line 1
ORA-00931: missing identifier
Disconnected
Can anyone tell what is the error?
Do we have to create a thesaurus 'default' before only and then load it using 'ctxload' command?
Please can anybody explain how to create and load a thesarus?
Thank You

It appears it is expecting "ctxload -thes", not just "ctxload", even though "-thes" is not listed as part of the required syntax. It also requries that the default thesaurus does not already exist, so if you have one, then drop it. Below I have first reproduced your error, then added "-thes" with an already existing default thesaurus, showing what happens then, then dropped the default thesaurus, then demonstrated a correct load.
