Procedure documentationAdding Data Volumes Locate this document in the navigation structure


The database system saves the data of a database permanently in data volumes (data area). If the data area of the database is full, the database stops working. Therefore, you need to monitor the database fill level and add new data volumes as required.

Note Note

You can configure the database system to add data volumes automatically as required.

More information: Activating or Deactivating Automatic Extension of the Data Area.

End of the note.


  • You are logged on to the database as the database system administrator or as a DBM operator with server authorization for accessing database parameters or utility sessions.

    More information: Glossary, Server Permission

  • To create a new data volume, the database parameter value MaxDataVolumes must be at least as high as the sum of the number of existing data volumes and the number of data volumes that are to be defined.

    More information: Changing Database Parameters

    Note Note

    Every time the database instance is started, the system checks whether there is enough space available for at least one volume of each type. If not, it automatically increases the value of the appropriate database parameter by 1.
