Last week, while creating a new datafile for an expanding tablespace I
received the ORA-00059
(max number of db_file exceeded). The DB is used
in a 24/24 env. So I can't easily plan a bounce to change my db_files
parameter from 151 to 250 for example.
Now, I'm wondering if the actual datafile size set by the previous DBA
on this DB, which is 4 Gb, is ok or if I could start increasing this
size to 8Gb for example. I normally set my datafile size to be a
portion of the disk size so that I can easily move datafiles around if
needed. But here, the disks are stripped on a big 900 Gb array. So the
need to keep the datafile size down is not really relevant anymore.
This DB is approx. 600 Gb and growing of approx. 1 Gb every 2 weeks.
Here are my questions:
- What would be the best max size for my datafiles?
- What sizes are you guys using?
- What should I take into consideration when deciding this?
Thx in advance
