Procedure documentation Changing Database Parameters for Volumes Locate the document in its SAP Library structure

You can use the Database Manager GUI to define database parameters, including those that define the maximum number of volumes in a database instance: the general database parameters MAXDATAVOLUMES and MAXLOGVOLUMES.

You can change the settings of both database parameters at a later time, regardless of the operational state of the database instance. Like all database parameter changes, these changes take effect the next time the database instance is restarted.

Procedure

...

       1.      For the database parameters MAXDATAVOLUMES and MAXLOGVOLUMES, proceed as described in Displaying and Changing Database Parameters.

    2.      Transfer the database instance to the operational state ADMIN.

       3.      Start the database instance.
The Database Manager GUI transfers the database instance to the operational state OFFLINE and then to the operational state ONLINE, and saves the new value of the database parameter in the parameter file.
The Database Manager GUI reserves the memory required by this number of volumes, plus reserve memory large enough for the largest volume of this type. This reserve allows you to create an additional volume of this type while the database is running if the original number of volumes is not enough.
