I need your advise about planning database storage.
We have the database with partitioning for IOT tables.
We used IOT for time-series data.
These tables belong one tablespace.The tablespaces was
split by 2000 MB data files and total size is 68GB ..
We are going to create new database with the same schema.
Should we create one or three big data files or create a lot small.
We will use Linux 64-bit.What is the better way for IOT with partitioning ?
Originally posted by davey23uk yes, if you need to recover a 10Gb from tape, will take longer than a 2gb file for example. If you are restoring a whole database wont make much difference
sorta of maybe - depeneds on how many blocks in the datafile ever contained data
- so if you have a new 10gb df with zero blocks it could conceivably recover faster than a 2gb df all packed up with blocks that at some time had/has data
