Dear Sir I would appreciate your advice on the following :- I have been unable to find any references to tuning parameters for a database. Hence when a database is mounted and opened these tuning parameters come into operation. This is so in oracle where tuning parameters are placed in the init.ora file. Once a database has been created then does it need to be opened for any operation, ie. query by a user. Or is the the case that only the postmaster has to be up and running. Thank you Raj Arya
