Since ITM6.2 FP1, a tacmd
command has been introduced to remove OFFLINE agents, either individiually, or in bulk.

USAGE:

tacmd cleanms {-m|–systems} MANAGEDSYSTEM NAME

tacmd cleanms {-a|–all}

-m|–systems

Specifies the name of the offline managed system(s) in the Tivoli Enterprise Monitoring Server.

-a|–all

Clears all the offline managed system entries present in the Tivoli Enterprise Monitoring Server.

Note:

There are some javascripts I’ve seen which do this in ITM6.1 via a series of SOAP calls updating the EIB tables, as soon as I get my hands on one I’ll post it in scripts here.
