I think, I need to answer this original post( late,
because our time zone is different ;-))
I was doing this in the test environment ( which I
mentioned in my original post too) with total database
size of 250 Mb. To make the testing easier I had adopted
some random method. At that point of time I didn't care
whether I choose method 1 or method 2 ( described below).
My motive was to design and document a full proof method for
recovery from Hotbackup in case of any kind of failure.
Somehow I was missing the clue in one of the test cases and
I posted the query describing my original steps honestly....
BTW I am aware of consequences of putting all the TS
( of Production environment) in backup mode in one stretch
for hot backup purpose. Any-way, I thank everybody for
contributing.
Thanks again everybody,
Rajesh

Hello,
Slightly unrelated question... is it better to (in pseudo code) :
1)
for each tablespace loop
put tablespace in backup mode
end loop
for each datafile in the database loop
copy data file
end loop
for each tablespace loop
put tablespace in normal mode
end loop
or 2)
for each tablespace loop
put tablespace in backup mode
for each datafile in this tablespace loop
copy data file
end loop
put tablespace in normal mode
end loop
What I'm doing is (2), but I notice that Rajesh is doing (1). What are
the pros and cons of each approach? (I'll probably use RMAN at some
point, anyway :0) ).
Cheers,
g
