This is the architecture of the Oracle Enterprise Manager (OEM): an OEM "console" has the ability to send "scripts" for execution on a "remote agent", that is, an individual monitored server. A restricted form of Tcl (version 8.0, as of 2001?) is the language of these scripts.
OEM is built with Oratcl.
CL believes that one of the reasons Oracle chose Tcl over Perl for OEM is the former's achievement in SNMP applications.
