3.1.2 Serviceguard WBEM Provider
3.1.2.1 What is WBEM?
Web-Based Enterprise Management (WBEM) is a set of management and Internet standard
technologies developed to unify the management of distributed computing environments, facilitating
the exchange of data across otherwise disparate technologies and platforms. WBEM is based on
Internet standards and Distributed Management Task Force (DMTF) open standards: Common
Information Model (CIM) infrastructure and schema, CIM-XML, CIM operations over HTTP, and
WS-Management.

3.1.2.2 Support for Serviceguard WBEM Provider
Serviceguard WBEM provider allows you to get the basic Serviceguard cluster information via the
Common Information Model object Manager (CIMOM) technology. It also sends notification
(WBEM Indications) of Serviceguard cluster events to Serviceguard WBEM Indication subscribers
that have registered a subscription with the SFCB (for SUSE Linux Enterprise Server) or cimserver
(for Red Hat Enterprise Linux Server). For example, an indication is sent when the cluster
configuration changes, or when a Serviceguard package fails.
To use the Serviceguard WBEM provider:
1. Verify whether the SGProviders rpm is installed:
rpm -qa | fgrep sgproviders
2. If it is not installed, install the rpm. For example,
On SUSE Linux Enterprise Server 11
rpm —ivh sgproviders-A.04.00.10-0.sles11.x86_64.rpm
