It looks like you are trying to use an incorrect version of the library. That probably means that the location for the library is incorrect. Look in DBA_LIBRARIES to check, and CREATE OR REPLACE LIBRARY to fix if necessary. Alternatively, you may be able to just switch links under Unix to achieve the same effect.

I have installed intermedia on oracle 8.1.5 runnning on a Solaris box. I am able to create the Context index on a table. But when I try to select using the CONTAINS clause as below, it gives the error as given below.

SQL> select * from v where contains(b, 'senni')>0;
select * from v where contains(b, 'senni')>0
