Web-Based Enterprise Management (WBEM) (http://www.dmtf.org/) is a platform and resource independent Distributed
Management Task Force (DMTF) standard that defines both a common
model (i.e., description) and protocol (i.e., interface) for monitoring
and controlling a diverse set of resources.
The HP WBEM Services for HP-UX version A.02.05 is the HP-UX
implementation of the DMTF WBEM standard for release on HP-UX 11i
v3.
This product is based on The Open Group (TOG) Pegasus Open
Source Software (OSS) project (http://www.openpegasus.org/).

Impact |
|
HP WBEM Services for HP-UX allows customers to manage their
HP-UX systems, providing integrated solutions that optimize a customer’s
infrastructure for greater operational efficiency.
Compatibility |
|
Starting with the A.02.05 release, HP WBEM Services for HP-UX
will support an option that allows a WBEM Provider (i.e., the management
instrumentation) to run as the user who issued the management request.
Prior to this release, all WBEM Providers executed in a privileged
context. With the release of HP-UX 11i v3, WBEM Providers will,
by default, be invoked in the context of the user requesting an
operation (i.e., “Run-As-Requestor”). This default
setting can break backward compatibility for certain types of Providers.
This means that existing Providers that run in the user context
of the CIM Server may break. To remedy this situation, developers
have the following alternatives:
To continue running their
Provider in a privileged context, developers will need to explicitly
register their Provider to run in a “Privileged User” context.
This is a configuration file change and should not require a change
to the Provider library. That is, developers will not be required
to recompile/relink their providers to continue running in a privileged
context.
To register their Provider to run in a “Privileged User ” context,
developers need to modify the PG_ProviderModule instance definition in their Provider Registration mof
as follows:
Change
the InterfaceVersion from “2.1.0” to
“2.5.0”
Add the new property UserContext =
2
Example using an updated PG_ProviderModule instance definition for the OperatingSystem Provider
Module:
instance of PG_ProviderModule
{
Name = "OperatingSystemModule";
Vendor = "OpenPegasus";
Version = "2.0.0";
InterfaceType = "C++Default";
InterfaceVersion = "2.5.0";
Location = "OSProvider";
UserContext = 2;
};
To support running in the “Requestor” context,
developers need to ensure that their Provider has been written to
allow multiple instances of the Provider to run at the same time
(in different user contexts). In some cases, the Provider may need
to coordinate the actions of the Provider instances. In cases where
the Provider is simply a “pass-through” to a managed
resource, no coordination may be necessary.
In addition, providers running in the “Requestor” context
must only perform privileged operations if those operations are
only expected/required to succeed when invoked by a user who already
has the necessary privileges.
