And do they use PUBLIC synonyms or not? If so, have they only different public synonyms or some of them are common?

thanks blackswan, well the schemas are same but inside each table we are maintaining a seperating field called company code.Basically we have to branches one branch uses company code 'QAR' and the other uses 'RIO' , But one more challenge is some of the procedures may vary at the block level and some schema objects may be created on both sides additionally.

Challenges are.

1) Identify the objects which are different
2) List out the programs that are different
3) merge them together , so when people from RIO wants to connect they will be accessed to their schema alone and when people from QAR they will be logged into theirs.
4) What kind of interface will be suitable as we are using 9ias and they will be using VPN.
