Hi,
You can clear out your RME database using the following on a Solaris Platform
opt/CSCOpx/bin/perl /opt/CSCOpx/bin/dbRestoreOrig.pl dsn=rme dmprefix=Essentials npwd=*your-new-password*
I have done this in the past on a Solaris box, plus also i've flushed the ANI database too, all without any issues...
The following link shows a bit more detail on how to do this on Solaris AND Windows:

Good luck
