Measures reported by AsSysDBSpaTest

The data volumes of a database form the data area. The database system stores the following in the data area:

  • Application data

  • Database catalog

  • The converter saved at the last savepoint

  • Undo log files

  • Sequences

  • Restart information

The log volumes of a database form the log area. The database system permanently stores the redo log entries (after images) in the log area.

For the data to be stored seamlessly in the SAP database, there should be adequate space available in both the data area and log area. A potential space crunch when detected at the earliest will help administrators plan the size of the database accordingly and help avert data loss. The AsSysDBSpaTest test helps administrators track the space utilization of each type of volume in the SAP database.

For each type of volume available in the SAP database, this test reports the space that had been utilized and the space that is available for use. Using this test, administrators can figure out the volume that is currently running out of space.

Outputs of the test : One set of results for each type of volume of the SAP database of the target SAP ABAP System being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Used_space Indicates the percentage of space utilized in this type of volume in the database. Percentage A value close to 100% indicates that the volumes in the database are nearing their maximum capacity. Administrators are required to periodically free up space so that potential problem situation can be avoided.

Compare the value of this measure across the type of volumes to figure out the volume type that is currently running out of space.
Free_Space Indicates the amount of space available for use in this type of volume in the database. MB
