Note: HP renamed the product called now HP operations manager way too many times. Also it is very inconsistent with using abbreviations. Here we will assume that the term "HP Operations manager" and abbreviations HPOM, OMU, and OVO  mean the same thing :-)

The command to list processes is:opcsv -status

The following processes run on the HP Operations management server.

  1. opcactm  Action manager that feeds the action agents with automatic actions, operator-initiated actions, scheduled actions, and application startup and broadcasting information through the control agent. In addition, external instructions are determined using this mechanism.
  2. ovoareqsdr  Request sender that informs the control agents to start, stop, or update their local HPOM agents. The request sender is also responsible for the self-monitoring of HPOM manager services, and for the heartbeat-polling of the managed nodes.
  3. ovcd  Control daemon that controls and checks the status of processes and components, which are registered with it.
  4. opcdispm Display manager that serves HPOM GUIs. The display manager also feeds the action manager with operator-initiated actions, application startup information (not requiring a separate terminal), and broadcasting information issued by operators. It also serves clients connected to the MSI for message and configuration changes. Several HPOM user GUIs may be active at the same time.
  5. opcbbcdist  Configuration management adapter between the HP Operations management server and the HTTPS agents that creates instrumentation from existing actions, commands, and monitors, and switches nodeinfo settings into the XPL format used on HTTPS nodes.
  6. opcecm Event correlation manager that connects to the server MSI to allow access to and modification of messages from the HPOM message flow by the event correlation (EC) engine. Depending on filters and conditions, the messages are then correlated and written back to HPOM. The messages display in the Message Details window (available from the Message Browser) with the message source MSI opcecm. Like all server processes, the event correlation manager is controlled by the OV Control, ovcd.
  7. opcecmas  Annotation server that runs on the management server and obtains data from outside the ECS engine for use within correlation circuits. This process connects to the opcecm process using the standard annotate API. It receives annotate requests for launching external programs and returns the output to the circuit. opcmsgm Message manager that receives messages from the managed nodes through the message receiver (opcmsgrb). The messages can be correlated, regrouped and logged by the message manager running on the management server. The message manager is also responsible for adding annotations, triggering notifications, and forwarding the message to the trouble ticket and notification service manager for external notification and trouble ticket generation.
  8. opcforwm Message forwarding manager that relieves the message manager, opcmsgm, of time-consuming tasks (for example, sending messages to remote managers). This relief allows the message manager to manage messages more effectively. On the local “source” management server, the message forwarding manager receives data from the message manager (in the form of messages), the action manager (action responses), and the display manager (message operations such as acknowledge, add annotation, and so on). The message forwarding manager sends data to the message receiver on the “target” management servers. opctss Distribution manager subprocesses that transfer configuration data to the distribution agent through TCP/IP.
  9. opcttnsm  Trouble ticket and notification service manager that feeds the external notification interface, as well as the external trouble ticket interface, with message attributes. This manager is an auxiliary process of the message manager designed to ensure high message throughput. If external instructions are specified for a message, the trouble ticket and notification service manager evaluates the help text through the action manager. Whenever the trouble ticket and notification service manager receives a message in its queue, it passes the message on to the trouble ticket interface or the external notification service. It does so by forking and executing the customer-defined program that receives the message (that is, the ticketing interface or the notification service). As soon as this program is finished and exited, a SIGCHLD is sent to the trouble ticket and notification service manager. The manager stops processing the message queue until it receives another SIGCHLD.
  10. opcuiwww  Server process that serves the HPOM Java-based operator GUI. This process forwards all communication requests between the Java GUI and the display manager. For each Java GUI, at least one server process is started.
  11. opcuihttps  Server process that acts as a proxy between the Java GUI client and the HPOM management server using the HTTPS protocol.
  12. opcsvcm  Service engine that maintains the global (operator-independent) service status and can log service changes into the database. By default, remote access to the service engine is disabled. See HPOM Developer’s Reference for information on how to allow remote access to the service engine.
Process Files on the HPOM Management Server

The files used by the HPOM management-server processes reside in the following directory: /var/opt/OV/share/tmp/OpC/mgmt_sv

The following list describes the queue files and pipes that the HPOM management-server processes use. For more information about the HPOM management-server processes themselves, see “Processes on the HPOM Management Server” on page 359:

In addition to its role as the primary manager for the managed nodes, the server functions as the repository for the agent software and components, including templates (which are converted into policies during distribution) and instrumentation (also known as actions, commands, and monitors). These components allow the HPOM administrator to define the systems, devices, and services within the management domain. The components' definition includes specific service levels for monitors, alarms, and corrective actions. The server includes a run-time version of NNM and the HPOM Oracle database. The server could also have other OpenView products installed for local use or for distribution to the nodes (such as SPIs, Service Navigator, ECS Designer, and so on).

Tasks Performed by the Server

The tasks performed by the management server include but are not limited to the following:
