Error ADA048 using adafin

Detailed explanation of the problem:

Hi together,

When using the Adabas utility adafin, we receive the error message shown in the attachment.
Here is the used command:

adafin db=${DBNR} file=* usage=ds.

I am aware that this error can occur when adafin tries to access superdescriptors.
However, as I understand it, that is not the case with this command.
Where am I going wrong? Could the error have something to do with the Linux version we’re using (6.6.0.2)?

Are any files locked for exclusive use? Check the DIB for utility locks - such as another utility running or failed.
