Guy,
Some reasons why NOT to put all tablespaces in the backup mode at once (step 1) is
that the tranactions against the database could create a lot of redo and archive logs
that could fill the space, tranaction time could be longer as it now reads the redo
not the tables, Snapshot to old could occur, If there is a problem and the server
restarts Oracle will not start tablespaces in the backup mode you have to manually
issue the "tablespace normal" command.
Doing each tablespace individually allow you more control over the process.
Just a few thoughts.

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
