I have my tables, indexes, system, etc. on different mount
points. That was suggested by several of the gurus when I was getting
ready to move to new servers.

1.
No. In fact, there are all kinds of reasons NOT to keep them on
one mount point. Everything from Speed to Safety. When I built
our 7.3.4 database I used 64 mount points. 2. Yes. You can split a
tablespace up all over the place. Just put the different data files
on different mount points. 3. No. In fact, I prefer doing
this. Maintenance is a lot easier. 4. No..... but who knows
about 10 because its not here yet.

I am part-time DBA for an Oracle system that for
reasons beyond our control is frozen at 7.3.4, at least for
the immediate future. I am having some problems and I think I know
how to correct them but I am asking the old-timers to dust off their brains
to tell me if my proposals are O.K.
It started when I noticed that
one of the tables had gone into 2 extents. Normally when this
happens, I (in a nutshell), make a copy of the table with larger storage
parameters. But for this table, I get the following error
message:
ORA-01658: unable to create INITIAL extent for
segment
in tablespace ORA_DATA1
I also noticed that this system has 3 mount
points. When I look at the capacity of the disks, the first is
always 89 percent full and the other two are 1 percent. This
is because all the DBF files for tablespaces were created on the first
mount point. So all the other two have are small control and redo-log
files.
So what I would like to do to fix all of this is to move some
of the tablespaces onto the other 2 mount points. I would also like
to create a couple of new tablespaces, one to store two large
application-related tables and another to store a large table that gets
dropped and recreated everyday (a local copy of data from an external
system).
So my questions are: 1) Is there any reason to keep
all the tablespaces on one mount point?
2) I know about keeping table data and indexes in
different tablespaces but can they also be on
different mount points? 3) Any reason for not putting my 1 large
temp-table into its own tablespace? 4)
If I can do all of this, will anything significantly
change in Oracle 8, 9, 10, ...?
I have read
different manuals and references but I have not seen anything that
indicates that I cannot do what I am proposing. I have tried this solution
on a test 8.1.6 database and everything seems to be working.
