sql - Oracle 10g Import Export question -

-

i new oracle. have 2 oracle 10g systems running. need export database in 1 system , import dmp file oracle system using exp , imp commands

i cannot use data pumps.

questions 1- when exporting , importing databases, must stop databases running ? need exp , imp them while databases running. cannot stop dbs running. 2- sql query find out
a) db system priviledges user has. need find out if user has priviledge imp , exp. b) how create , add new user able exp , imp databases 3- in using imp command, can fromuser , touser values same user value ? 4- must drop db on target box before import prevent object duplication errors ?

any appreciated.

thank you. sincerely.

  1. no don't need stop database. might want use consistent=y

  2. select * user_sys_privs though user doesn't need special privileges export own schema or import own schema. in latter may need create table etc.

  3. if fromuser , touser same don't need specify either

  4. you don't want drop database (unless going rman database clone). might want drop existing schema objects.

if going move entire database, rather schema, i'd rman rather imp/exp unless database small (eg < 10 gbs)
