IBM Enterprise Console manual OpenView Adapter, OpenView Driver, Reception of OpenView Messages

Chapter 5. OpenView Adapter

The IBM Tivoli Enterprise Console adapter for the Hewlett-Packard OpenView (HPOV) product forwards events from OpenView to the event server. The adapter is registered with the startup configuration of the OpenView operating system using ovaddobj, so it is started along with all the other applications that use the operating system. The OpenView ovspmd process manages the adapter and forwards all preferred events to the event server.

This chapter explains how to configure and start the OpenView adapter.

OpenView Driver

The OpenView adapter collects OpenView trap messages that have been sent by OpenView trap daemon (ovtrapd) and processed by the ovspmd daemon. The adapter translates the trap messages into the appropriate IBM Tivoli Enterprise Console class based on the entry that the trap matches in the .cds file.

Reception of OpenView Messages

In order to receive events generated by the OpenView Network Node Manager (NNM) and any events from all possible OpenView agents, the OpenView adapter registers itself into the NNM SUF startup file using the ovaddobj command. The ovspmd daemon reads SUF at startup and manages all the registered processes it finds, then receives events from the ovtrapd process and forwards the specified events to the appropriate registered applications (such as the OpenView adapter).

The OpenView adapter must run as a well-behaved daemon process using the OVsPMD API (application programming interface) functions provided with OpenView. The OVsPMD API functions are used by object managers (agents) that must run as background processes in the OpenView program in order to be managed by ovspmd, the process management daemon. The adapter interacts with ovspmd using the SNMP API functions provided with OpenView NNM. This involves the following steps:

vIn NNM 5, calling OVsnmpTrapOpen to establish a logical session with the OVsnmpAPI to receive SNMP events through the OpenView Event Framework.

vIn NNM 6, calling OVsnmpEventOpen to establish a logical session with the OVsnmpAPI to receive SNMP events through the OpenView Event Framework.

vCalling OVsinit to get a socket for communication with the ovspmd process.

vCalling OVslnitComplete to notify at the end of the initialization, the status of the initialization process.

vCalling OVsReceive to receive commands from the ovspmd process.

vCalling OVsDone to notify ovspmd that the adapter is being shut down.

Determining the OpenView NNM Version

To determine which version of OpenView NNM you are running, use the following command:

$OV_BIN/ovnnmversion
