HP WBEM Services for HP-UX and Linux System Administrator's Guide

Example of a Client Request
Example Request
Chapter 4 37
— The client must be able to connect to the system on the
authorized port.
— CIM Server must be running.
— The user/password pair must pass authorization.
— The request must have a properly formed header.
— When the request is parsed, it must not contain xml errors.
• Lines 4 and 5: At this point, HP WBEM Services considers the
operation that is requested. If it is a supported operation, the process
continues.
• Lines 6 - 9: Two criteria must be met to continue:
— This namespace must be valid.
—If enableNamespaceAuthorization property is enabled, this
user must be authorized to access this namespace
• Lines 10 - 12: The classname must exist, and it must have a provider
registered. The provider must respond to the request. Here, the OS
Provider is registered for the PG_OperatingSystem class. Checking
the provider documentation, you can see that it supports the
EnumerateInstances method.
Now it is up to the provider to process the request and send a response. If
the resource does not respond, HP WBEM Services will send a message
to the client. If the resource sends its own error, HP WBEM Services will
pass this on to the client in its response. Often, these messages will be
appended to a standard CIM error.
