Measures reported by OraDBFileGrowthTest
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 OraDBFileGrowthTest monitors the usage of the datafiles that underlie a managed Oracle database instance, and indicates if any of the datafiles require resizing. The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| File_size |
The current size of this datafile |
MB
|
|
| Used_size |
The amount of database space that has been currently utilized by this datafile |
MB
|
|
| Free_size |
The amount of free space currently available for this datafile |
MB
|
|
| Used_percentage |
The percentage of database space that has been utilized by this datafile |
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 for this datafile |
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 for a datafile could significantly deteriorate database performance. Under such circumstances therefore, you might want to resize that particular datafile or reorganize all the datafiles that are present in the managed database instance. |
