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:
