HI this is ramesh please tell me the sum minimum size's for db, table space, redologs, how manay redologs for 1 db in real time, how much time takes to clone the db, db contains how many tables, how many table spaces, in the interviews about which errors they will ask,etc.
for the interview point of view you study the concepts well.
minimum no of tablespaces,datafiles for a small realtime database can be 1
other than system tablespace.
the minimum size of db can be 1 GB or more depending on the database.
the database size is sum of space occupied by all datafiles used
for that database.
you can query dba_data_files, dba_tablepsaces etc.. views
