Hi Frank,
It is a bit farcial really, but if you enter the diagnositc shell in OCUM then you can access the reports as they are stored in the filesystem. I took it out and tweaked it with that Eclipse tool.
The alternative, which I tried first, is to reverse engineer the over-commited value using an advanced computed column within OCUM. A lot simpler, but it will only give you over-committment, not actual committment.
