EM 12c, EM 13c: How to Increase the size of a Tablespace using Enterprise Manager Cloud Control (Doc ID 1929325.1)

Last updated on MARCH 08, 2017

Applies to:

Enterprise Manager for Oracle Database - Version 12.1.0.1.0 and later
Information in this document applies to any platform.
Metric alert for Database Instance "Tablespace Space Used (%)" in Enterprise Manager 12c
Metric alert for Cluster Database "Tablespace Space Used (%)" in Enterprise Manager 12c

Goal

To increase the size of a tablespace using Enterprise Manager Cloud Control.

Enterprise Manager can be configured to send a notification when the size of a tablespace crosses a user specified threshold.  By default a 'warning' alert is generated at 85% and a critical at 97%, but these thresholds can be edited appropriately by the Enterprise Manager user.  When a tablespace crosses the specified threshold an event will be generated in 'incident manager'.  Either in "events without incidents" (for a warning), or in "all open incidents" for a critical (if using the default Oracle provided incident rule).  The accompanying text will be:-

Tablespace <tablespace name> is <n> percent full

This article discusses the action to take when the tablespace is genuinely full and needs more space.

If the metric has been raised erroneously see:
