Adding a datafile maxdb Linux / db_addvolume

Hello Folks,

I need some help in extending the current MaxDb database.

I have installed the 90 days Eval vesrion of WAS 640 on Linux/MaxDb. It by default instls with one datafile of nearly 6GB.

I have installed the SAPDBMGUI on Windows to manage the MaxDB on linux.

When I try to add the datafile from DBMGUI, its not allowing me to add.. Its throwing an error link file cannot be created.

I would highly appreciate your help if some one can give me some clue on this.

Thanks
