Hi,

Why not run ontape -r -D <dbpsace list>
You can restore only chunks of these dbspaces and the rootdbs,
physical and logical log ...
You can create a little dbspace temp .... after that.
You have to modify your ONCONFIG file, in line ONDBSPACEDOWN change to
0 (zero) - means 'CONTINUE', because the deamon oninit will not find
all dbspaces.

I hope it helps you.

Regards. R. Ferronato
