DBA_TABLESPACES

This is a dynamic performance view equivalent to the SYS.TS$ table containing information on all tablespaces; the only difference is that DBA_TABLESPACES doesn't list dropped tablespaces.

Fields

The most relevant view fields are as follows:

  • TABLESPACE_NAME: The name of the tablespace
  • BLOCK_SIZE: The database block size used in the tablespace
  • STATUS: This can be ONLINE, OFFLINE, or READ ONLY
  • CONTENTS: This can be UNDO, PERMANENT, or TEMPORARY
  • LOGGING: This can be LOGGING or NOLOGGING
  • EXTENT_MANAGEMENT: This can be DICTIONARY for dictionary managed or LOCAL for locally managed tablespaces
  • ALLOCATION_TYPE: This can be SYSTEM, USER, or UNIFORM
