An Overview of ITO Processes
Understanding ITO Processes
opcmsgr The message receiver collects all messages from
managed nodes; it is an auxiliary process of the
message manager, designed to guarantee quick
message acceptance. opcmsgr accepts messages from
NCS agents only.
opcmsgrd Similar to opcmsgr, opcmsgrd accepts messages from
NCS, DCE, and Sun-RPC agents.
opctss The distribution manager subprocesses (opctss)
transfer configuration data to the distribution agent
using TCP/IP.
opcttnsm The trouble-ticket and notification-service
manager feeds the external notification interface and/
or the external trouble-ticket interface with the
appropriate message attributes. It is only an auxiliary
process of the message manager, designed to
guarantee high message throughput. If an external
instruction text is specified for a message, opcttnsm
evaluates this help text by way of the Action Manager.
opcuiadm The ITO GUI for the ITO administrator, required for
the administrator’s configuration activities. Note that
an additional opcuiopadm process is started. Runs as
user root.
opcuiop The ITO GUI for the ITO operator for message
browsing and application startup. One instance of
opcuiop runs for each operator. Runs as the operator’s
unix user.
opcuiopadm The ITO GUI for the ITO administrator, required for
the administrator’s operator functionality (message
browsing, application startup). Runs as the ITO
administrator’s unix user.
opcuitadm The ITO GUI for the ITO template administrator,
required for the template administrator’s configuration
activities. Runs as user root.
opcuiwww The opcuiwww server process serves the ITO Java-
based operator GUIs. It forwards all communication
requests between the Java-based GUIs and the
display manager.
