Move Objects From One Tablespace to Another Tablespace in Oracle

Sometimes need to move objects from one Tablespace to another in Oracle Databases. We can do this multiple ways.

  • Move a single object from Multiple Tablespace (one TBS for DATA, another for Index and LOB) to different set of Tablespace
  • Move all objects of a schema from Multiple Tablespace (one TBS for DATA, another for Index and LOB) to different set of Tablespace
  • Move all objects from one Tablespace to another Tablespace

Script for moving a single object to one/multiple Tablespace

Instruction to execute the Script:

This is recommended and best practices to use separate tablespace for DATA, Index and LOB Segment.

  • 1st Input : Object Owner Name
  • 2nd Input: Object Name
  • 3rd Input: Target Tablespace Name for DATA
  • 4th Input: Target Tablespace Name for INDEX
  • 5th Input: Target Tablespace Name for LOB
  • 6th Input: Enter “EXECUTE” or 1 to Execute Command Immediately Or Enter “SHOW” to Show / Generate Command as output.

NOTE::: If same tablespace for DATA, INDEX and LOB then provide same tablespace name for all inputs [3-5]
