just delete the machine?
you can use the "show old machines" API command to list them, sanitize the list, then use the "deletemachine" api command to remove them?
I am fairly new to EEPC what are the commands or is that option part of the GUI?
you're best off reading the scripting guide included in the documentation - but,
sbadmcl -command:deletemachine -help
from a command prompt will get you the basics.
don't for get to include -adminuser: and (-adminpwd/-adminauth) in any database specific command, they are not listed in the help because it's assumed you realize that.
