Oracle SQL Developer error - "The file-based source procedure Name is not present in the database."

Question

I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name>  is not present in the database.  Was it compiled?'
instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

Answer 1

Sounds like you do not have the correct privileges.  What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest?  If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
The role SELECT_CATALOG_ROLE
The system privilege SELECT ANY DICTIONARY
And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
The role EXECUTE_CATALOG_ROLE
The system privilege EXECUTE ANY PROCEDURE
Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.
