Monitoring disk usage

Regularly monitor tablespaces to ensure that they do not run out of disk space. When archive logs are turned on, regular backups are necessary to ensure that the logs are removed and disk space is optimized.

For login instructions, see “OEM Console login” on page 45.

At the Oracle Enterprise Manager

1Login to the OEM Console as oracle.

2Select the Storage node and expand it.

A list of tablespaces and data files present in the system displays.

3Select each tablespace to determine its size, where it is stored, and how much space is available.

Note: In the unlikely event that a tablespace should become full, contact your next level of support for assistance.
