Prerequisites for Installing ITO Agent Software
Managed Node Requirements
Communication Software
ITO can use two mechanisms to communicate between the management
server and the client nodes, these are the Distributed Computing
Environment (DCE) and Network Computing System (NCS). Processes
running on the ITO management server communicate using DCE by
default, however, processes on the agents can communicate with the
management server using either DCE or NCS. DCE is the recommended
communication mechanism wherever possible. Table 1-2 on page 33
shows which version of DCE is required for a given agent operating
system.
Table 1-2 DCE version for ITO-Agent Operating Systems
If DCE runtime is not available with your other agent platforms, you will
need to use NCS 1.5.1, with the Local Location Broker Daemon (llbd)
instead of dced/rpcd running on the managed node.
NOTE Starting with DCE version 1.4.1, the DCE daemon (dced) replaces the
RPC daemon (rpcd).
For platforms which support the NCS communication type, the following
configuration step applies. If DCE or NCS runtime is not found on the
managed node during installation, ITO automatically installs the
appropriate NCS components (the llbd and lb_admin programs) on
NCS nodes.
