Removing a Remote Instance Domain
To remove the "GRFR6" VNODE from the MIB server domain, it is necessary to update the classid 'exp.gwf.gwm.session.control.del_vnode'. Doing so does not actually change the value in the ima_mib_objects table, but is an instruction to remove the objects from the visible domain.
The following SQL update removes the remote instance domain:
UPDATE ima_mib_objects
SET value = 'GRFR6'
WHERE classid = 'exp.gwf.gwm.session.control.del_vnode'
AND instance = '0'
AND server = DBMSINFO('IMA_SERVER');
