Promotion Management: Set Tmp / Working directory

Hello,

I want to make a backup with Promotion Management for a big FileStore (20 GB). (BO 4.1 SP2 on Linux)

How can I change this directory? Thesystem always uses /tmp, but there is not enough space.

I have a separat ASP and there the tmp is set like:

Djava.io.tmpdir=/data/sap_bobj/enterprise_xi40/java/pjs/container/temp

but the System didn't use this parameter.

How can I fix this?

Thanks

Andreas
