22.3 PROBLEM SOLVING

The tools built into the OVO user environment help you solve and manage incidents as they arrive in the message browser. The messages indicate that the agent on the managed node recognized an event and the message about the event is forwarded to the server. The event-processing mechanism depends upon a variety of resources that must all function properly. When diagnosing problems within the OpenView environment using a structured approach to problem solving (described earlier in Section 22.1 of this chapter), it is important to isolate the problem and use proven methods to determine the root cause of the problem. The OpenView processing environment is organized into the following functional categories:

• Installation /De-installation

• Client/Server Communications

• Error handling

• Networking

• Database(s)

• Event and Message processing

• Background Processes and Services (NNM)

• Policies

• Client/Server Configuration

• Applications (out-of-the-box and add-on)

• Graphical User Interface (MOTIF or JAVA)

• Agents and Sub-Agents

• Smart Plug-Ins

• Backup/Recovery

• Security (built-in and add-on)

• High Availability (Service Guard, Veritas, Solaris, AIX, Tru-64)

• Various Vendor-specific operating system environments (HP, Sun, IBM, Microsoft, LINUX, Sequent)

When you decide where to begin the troubleshooting process (such as the management server or managed node), you can locate the specific problem-solving resources. The most current information on diagnosing and resolving OVO problems is available at the OpenView support web site: http://support.openview.hp.com. The documentation, troubleshooting tools, software patches, and access to a worldwide OpenView user and support community are just a click away!
