Maximum size for data files ?

Posted on 2001-06-12
Last Modified: 2012-06-27
I would like to know if Oracle has a maximum allowable size for a single data file ? - especially on VMS platforms. We currently have single datafiles up to 6 gb but a third party has told us that Oracle will not function properly with datafiles over 4 GB. I cannot find any reference to this in the Oracle documentation.

This is strictly dependent upon the OS although Oracle
cannot deal with export files over 2gb, datafiles
limits ar OS dependent

Well,  as of  -- this was true --  I have not seen any information for version post

With data files > 4GB in OpenVMS -- you run into the possibility of generating some severe errors.
This was Bug No.    1369870,  which was discovered during a migration from 7.3.4 to 8.1.6

This is a clipping from some oracle support documentation:
 This problem occurred because you have one or more datafiles that  
 are larger than 4GB, the maximum allowable filesize limit on OpenVMS.

 In previous versions of Oracle on OpenVMS, you could have datafiles
 (by extension) larger than 4GB.  The documentation in all versions
 clearly states that the filesize limit on OpenVMS is 4GB.

 In, Oracle does not allow a datafile larger than 4GB, even
 if that file was smaller than 4GB at creation time and later extended
 beyond 4GB.

 You need to check the size of your datafiles when you plan the migration.
 If you have files that are larger than 4GB, you need to reorganize your
 data before the migration so that it is distributed in files that are no
 larger than 4GB.

hope this answers your question,
