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.
