Features and features of CIM on z/OS

The Public Information Model CIM (Common information Model) is a conceptual one that is independent of implementation and describes management information. There are many different implementations of CIM, and Open Pegasus is one of them. Open Pegasus is DMTF (distributed Management Task Force) CIM (Common information Model) and WBEM (web-based Enterprise Manage ment) standard open source implementation. For different platforms, Open Pegasus has its own porting. This article provides a general overview of the implemented features and features on the CIM on z/OS

1. Features and features of CIM Server on z/OS

1.1 Repository Automatic Upgrade

When the CIM server is started, by default, the current repository version and the version under/var/wbem/repository are checked and compared. If the current version is newer, the/var/wbem/repository is backed up and then automatically upgraded.

1.2 Support for ZIIP

As you know, CIM is generally used to manage and monitor systems. And Zos's CP resources are invaluable. As a result, the CIM on ZOS provides support for ZIIP and can be run on ZIIP. This will save a lot of valuable computing resources.

Characteristics of 1.3 log mechanism

In addition to the usual Openpegasus support for log and Trace, CIM on Z also adds support for SMF. Its corresponding record Type is 86

1.4 Support for ARM and Sysplex

For each OS Image for each Sysplex, there is a CIM Server. When the CIM server is started with the started task, the CIM server is registered to arm (Automatic restart Manager). When one OS Image shuts down normally, the CIM Server also logs off from arm. Figure 1-01

1.5 Support for the Zos System console

CIM on Z provides support for the Zos System console in addition to the usual support for the CIM command line. For example, you can use/S CFZCIM to start CIM in 3270 Windows

2. Features and features of CIM Provider on z/OS

2.1 Classification of existing CIM provider

For the needs of different platforms, each platform has its own implementation of the CIM Provider. The general classification of the provider that Zos has implemented is listed below. For reference.

Figure 2-01

Osbase providers is a support for the basic resources of the system, such as Cpu,process

SMIs providers is a support to storage.

WLM providers is support for workload manager

JOB providers is support for JES2 and JES3.

Pdworkbench providers is a support for system failure analysis

RMF providers is a support for resource Monitor facility

CPM providers is the support of capacity provisioning

Cluster Providers is a support to Sysplex.

2.2 CIM provider support for running in a stand-alone address space

This column more highlights: http://www.bianceng.cnhttp://www.bianceng.cn/OS/other/

CIM on Z supports the provider and CIM Server shared address space operations, while also supporting the provider and CIM servers operating in separate address spaces.

3. Features on the CIM on z/OS Installation configuration

As shown in the following illustration, the CIM server stores/etc/wbem,/var/wbem, and/usr/lpp/wbem in approximately three places on z/OS. Where/usr/lpp/wbem is read-only content. The/ETC/WBEM places the environment variables and configuration information. Log and repository are placed under the/VAR/WBEM.

4.CIM on z/OS security

The security mechanism for Zos is always very strict, and CIM on Z follows this principle. On the basis of Openpegasus's own security system, Z/Os CIM adds many of the unique security features of Z to meet the high security requirements of host customers.
