RE: 2GB or not 2GB (datafile limit)? That is the question.

Rich, I think the answer depends on your OS. If the OS is configured to handle datafiles of 32G or larger then leave the setting alone. If your OS have a 4G file limit then change the settings and monitor the tablespace file space usage more closely than you would need to with a 32G file.

Subject: 2GB or not 2GB (datafile limit)? That is the question.

Many moons ago, way back in the 32-bit era when Y2K was a looming nightmare, I had instituted a policy that no Oracle datafile would be setup to grow larger than 2GB. This was due to some known bugs with files larger than 2GB on many platforms/filesystems at the time.

As I'm now looking at a vendor's ERP installation, I was about to reduce their max datafile size from 32GB to 2GB when I asked myself "Why?". Is there any valid sane reason to do this anymore? I do not expect the DB size to grow beyond a modest 100GB in the next two years. The server is an IBM P5 blade running AIX5.3 and using JFS filesystems. Other similar servers with other DBs (e.g. Sybase) currently handle db files in the 100's of GB with no problem.

I don't see any need to limit the datafile size to 2GB anymore. Anyone else?

TIA,
Rich
