Oracle Data File Size in WAS 620

Hi.

We are planning to install SAP in HP-UX 11.11 64 bit environment.

One thing we dicussed is what size of Oracle data file is suitable for SAP ?

Usually, we created 2GB Oracle data file but we are expecting that our database increase to 2TB.

Is there any limitation for Oracle data file size in SAP environment ?

Please recommend suitable oracle space management strategy.

Regards, Arnold.
