Measures reported by OraDBGrowthTest
Periodic monitoring of the usage of the database is essential to ensure that the database is always adequately sized to handle current and future loads. The OraDBGrowthTest monitors the usage of a managed Oracle database instance, and indicates if it requires resizing. The measures made by this test are as follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Total_size |
The total size of this database instance |
GB |
|
| Used_space |
The amount of database space that has been currently utilized |
GB |
|
| Free_space |
The amount of free space in this database instance currently |
GB |
|
| Used_percentage |
The percentage of database space that has been utilized |
Percent |
A low value is desired for this measure. A value close to 100% is a cause for concern. |
| Free_percentage |
The percentage of free space in this database instance |
Percent |
Ideally, this value should be high. A sudden/consistent decrease in the value of this measure could indicate excessive utilization of the database caused by a sporadic/steady increase in database activity. Very low free space in a database instance could significantly deteriorate its performance. Under such circumstances therefore, you might want to check the measures reported by the OraDbFileGrowthTest to figure out which datafile is consuming too much space. You might then want to resize the datafile. |
