Privileges require for a user to create CONTEXT indexes

Question

Hi all,
   RDBMS: 11.2.0.3
   SO.......: OEL 6.3
   What are the necessary privileges that have to be granted to a user to be able to create CONTEXT Indexes, for example. I have granted the CTXAPP to my user, but when i tryied to create the CONTEXT Index with the command bellow, i got an "insufficient privilege" error message.
   CREATE INDEX USR_DOCS.IDX_CTX_TAB_DOCUMENTOS_01 ON USR_DOCS.TAB_DOCUMENTOS(DOCUMENTO) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS ('SYNC (ON COMMIT)');

Answer 1

It depends on whether the user is trying to create the index on his own table in his own schema or on somebody else's table in somebody else's schema.  The following demonstrates minimal privileges (quota could be smaller) for user usr_docs to create the index on his own table in his own schema and for my_user to create the index on usr_docs table in usr_docs schema.
