- Hi Oracle Users!
- I am just beginning to learn about Oracle and I have some really basic
- questions. I have just started reading this newsgroup and the little I
- have read impresses me greatly. I would appreciate it if some kind person
- would send me some answers (whether in e-mail or another posting is fine --
- whatever you think is appropriate).
-
- 1) Is it better to create a small database initially and add tablespaces
- to the database instead of creating a large database initially?
-
- 2) Is it better to have lots of little tablespaces or fewer, larger
- tablespaces?
-
- 3) Are temporary tables and indices easily created/dropped within an
- application using Pro*C?
-
- 4) How do you completely destroy a database (i.e., no more datafiles,
- no more control files, no more anything; I want it to seem as if the
- database NEVER existed!)? Could I just remove all files associated
- with the database or is there some internal table that would be really
- upset if I did?
-
- 5) I created a tablespace, then dropped it (including contents). Why
- isn't the datafile removed and why does the row for the tablespace
- (status = INVALID) still exist in dba_tablespaces?
-
- 6) Is there any easy way to rename tables (aside from selecting into the
- new table and dropping the old table)? Likewise, is there any easy way
- to rename columns? The RDBMS I use now has simple rename commands:
- rename (old_table_name, new_table_name)
- rename_col (table, old_column_name, new_column_name)
- Does anything like this exist in Oracle?
-
- 7) How is fragmentation monitored and how is it repaired?
-
-
- If an FAQ file exists for this group, please tell me how I can get a copy. I
- don't want to rehash the same old questions over and over.
-
- Thank you,
- Marianne G. Pittorino
