Viewing Undo Information

You can use the Undo Management Details page in Oracle Enterprise Manager Database Express (EM Express) to view the following information about your undo configuration:

  • Name and current size of the undo tablespace

  • Auto extensible tablespace setting (Yes or No)

  • Current undo retention period

Note:

In a multitenant container database (CDB), the EM Express undo management features are available only in the root, not in the pluggable databases (PDBs).

To view undo information:

  1. In EM Express, from the Storage menu, select Undo Management.

    The Undo Management Details page appears.

  2. View the undo management information on the Undo Management Details page.
