To get SSID, go to DB2I. If this is part of data sharing, then I think the name you see is the group name, not SSID. To get SSID, issue "-dis group" command and look under SUBSYS column. DB2 address spaces will be prefixed with this name. Or you can just go to sdsf;st and dispaly all master address spaces using 'pre *mstr; owner *'. '-dis group' will also show if NFM is enabled.
