Database Tuning WAS 640 Preview Linux

Hi there,

after the installation of was 640 preview the db capacity is about 88 %.

So i try to add an additional volume with the windows database manager 7.5 .

Connecting works fine.

Configuration->Volumes shows the volumn DATA0001.

While trying to add an additional volume i got the error message "... the symbolic link does not exist...".

Questions:

1)Anybody did this operation with this "external Tool" ?

2)Is there an admin tool in the linux environment ?

Thanks for the help
