Perfomance with using synonyms
I have a question about synonym perfomance in oracle 9.2.0.4 64 bit on AIX 5.3
My DB has 6 schema (they are user database). On schema A, I have about 200 tables and I were created about 100 synonyms (public and private but number of private > public) for others. I read some documents about perfomance of using synonym in oracle and they said using synonyms can cause bad perfomance for database (especially for public synonym).
Actually, using synonym is bad ideas ! And they cause my db has bad perfomance ? And another question: Can show me scrip to determine which synonym is public/private ?
Thanks very much.
