SummaryOracle has limitation boundaries related with the db\_block\_size.Depending thedb\_block\_sizeyou can createdatafilesup to one specific size. For example:db\_block\_size | Datafile upper limit

\----------------------------------------------

2kb 8GB

4kb 16GB

8kb 32GB

16kb 64GB

32kb 128GBIf you have db\_block\_size=8Kb and try to create a datafile with size 33GB you will get the error:ORA-01144: File size (4224000 blocks) exceeds maximum of 4194303 blocksThe formula to calculate the max size is: db\_block\_size \* 4194303.The workaround to this situation is obvious. One simple solution is to createmultiple datafiles with smaller size. The othe is to useBigfile tablespacesBigfile tablespacesThis is a feature ofOracle 10g. A bigfile tablespace contains only one datafile (or tempfile) which can be as big as 2^32 (=4GB) blocks.create bigfile tablespace beeeg\_ts data file '/o1/dat/beeeg.dbf' size 2T;Bigfile tablespaces are supported only for locally managed tablespaces with automatic segment-space management (which is the default setting since Oracle 9i). There are two exceptions: locally managed undo and temporary tablespaces can be bigfile tablespaces, even though their segments are manually managed.The system and sysaux tablespace cannot be created as bigfile tablespace. Bigfile tablespaces should be used with automatic storage management, or other logical volume managers that support dynamically extensible logical volumes, striping and RAID.

其实就是用create bigfile tablespace来创建超大的表空间
