  • CIM and IBM I: What It Is and How It Works
    CIM and IBM i: What it is and how it works Li Gong Liu January 29, 2013 This article provides basic knowledge about Common Information Model (CIM) and explains how CIM works on IBM® i. It helps you understand CIM and the Web Based Enterprise Management (WBEM) technology, and briefs the relationship between the standardized technology and IBM i. What is CIM If you are new to CIM with IBM i knowledge, you are in the right place. CIM provides a standard way to model and expose management information. CIM has been available on IBM i since V5R4 by loading the IBM Universal Manageability Enablement (UME) licensed program, and 5770-UME license program is included in IBM i 6.1 and IBM i 7.1 with enhanced functions. Currently, it is free for use and is mainly used as an agent of IBM Systems Director to retrieve and monitor IBM i resources. CIM is one of the core standards of WBEM. WBEM is the set of management and Internet standard technologies that defines how data can be exchanged between the ever increasing disparate networks, devices, and applications used in today's IT environment. The Distributed Management Task Force (DMTF) defines the standards for WBEM, which includes CIM that can promote multivendor interoperability (and this is the base goal of WBEM). On IBM i, CIM is a specific product that is delivered. Combining CIM with the other products that IBM i provides, the complete WBEM solution can be provided. Often, WBEM functions are simply referred to as CIM. An example from Systems Director is CIM monitors.

  • Design of a WBEM-Based Management System for Ubiquitous Computing Servers
    Design of a WBEM-based Management System for Ubiquitous Computing Servers So-Jung Lee1, Mi-Jung Choi1, Sun-Mi Yoo1, James W. Hong1 Hee-Nam Cho2, Chang-Won Ahn2, Sung-In Jung2 1Dept. of Computer Science and Engineering, POSTECH 2Digital Home Research Division, ETRI {annie, mjchoi, sunny81, jwkhong}@postech.ac.kr, {hncho, ahn, sijung}@etri.re.kr Abstract As the Internet evolves and wireless network technologies develop, people’s need to get a network service at anytime from anywhere is growing, and the age of ubiquitous computing is coming in earnest. A ubiquitous computing server receives and processes lots of information from various sensors in a ubiquitous computing environment and plays a role in providing various useful services. In this paper, we analyze the requirements for managing the ubiquitous computing servers based on WBEM technologies which are being standardized in DMTF. We present the design of our management system, which satisfies the requirements. We also examine and compare available WBEM implementations by performing benchmarking testing. Based on the benchmarking results, we present our choice of WBEM implementation, which is being used for implementing our ubiquitous computing server management system. 1. Introduction As the Internet continues to grow and the wired/wireless network evolves, users want to get various services at anytime and anywhere by connecting to the network. The idea used to realize this service is ubiquitous computing. Ubiquitous computing is a new paradigm for distributed interactive systems, which moves computers into the background of people's attention while using them to support their activities and interactions in the workplace and beyond.

A Year-in-Review with Jeff Hilland Every year in our December issue, we take the opportunity to pause and reflect on the last twelve months. As we wrap up another highly productive year for DMTF, I’m happy to highlight the vast list of accomplishments the organization achieved in 2018: Technical Milestones Redfish Technical work on the Redfish® standard takes place in DMTF's Redfish Forum (formerly known as the Scalable Platforms Management Forum, or SPMF), with significant progress this year including: In April, DMTF announced that its Redfish standard has been adopted and published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as ISO/IEC 30115:2018. Redfish’s publication by ISO/IEC as an International standard for Information Technology is expected to further accelerate worldwide adoption and interoperability. Redfish 2018.1 was released in May, with additional schemas for LDAP/ActiveDirectory support, as well as Server Sent-Eventing (SSE), and more. As part of the Redfish 2018.1 release, DMTF also debuted its new Redfish Resource and Schema Guide – a human- readable guide to the Redfish Schema to help educate users of Redfish. In September, updated Redfish DCIM Schemas were released as version 0.8 of the Redfish Data Center Equipment (DCIM) Model. Also in September, Redfish version 2018.2 was released, adding support for OpenAPI 3.0, as well as telemetry streaming and eventing, and improved event subscription methods.
