eG Monitoring
 

Measures reported by OraRacDbGrowthTest

Periodic monitoring of the usage of the shared cluster storage is essential to ensure that the cluster is always adequately sized to handle current and future loads. The Oracle RAC Database Growth test monitors the usage of a shared storage, and indicates if it requires resizing.

Outputs of the test : One set of results for the Oracle cluster monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Aloc_size Indicates the amount of space currently allocated to the datafiles for use. GB  
Total_size Indicates the maximum size upto which the shared cluster storage can grow. GB  
Used_space Indicates the amount of space used by datafiles. GB  
Free_space Indicates the amount of space that is still unused by datafiles. GB  
Aloc_used_space Indicates the amount of allocated space currently used by the datafiles. GB  
Aloc_free_space Indicates the amount of allocated space that is still unused by the datafiles. GB  
Aloc_used_pct Indicates the percentage of allocated space that has been utilized by the datafiles. Percent If the USE MAX SIZE parameter of this test has been set to No, then the value of this measure will be computed using the following formula:

Used space/Total size of database * 100

If the USE MAX SIZE parameter of this test has been set to Yes, then the value of this measure will be computed using the following formula:

Used space/Maximum size upto which the database can grow * 100

Ideally, this value should be low. A value close to 100% is a cause for concern.
Aloc_free_pct Indicates the percentage of allocated space that is unused. Percent  
Used_percentage Indicates the percentage of max space that is currently used by datafiles. Percent  
Free_percentage Indicates the percentage of max space that is available for use. Percent
