4.6 Small Footprint CIM Broker and CIMOM

The Small Footprint CIM Broker (SFCB) replaces OpenWBEM for CIMOM activities in BCC. OES 2018 SP2 offer SFCB as the default CIMOM and CIM clients. When you install any OES components that depend on WBEM, SFCB and all of its corresponding packages are installed with the components. For information, see Small Footprint CIM Broker (SFCB) in the OES 2018 SP2: Planning and Implementation Guide.

IMPORTANT:SFCB must be running and working properly whenever you modify the settings for BCC, the cluster, and the cluster resources.

Port 5989 is the default setting for Secure HTTP (HTTPS) communications. If you are using a firewall, the port must be opened for CIMOM communications.

The Clusters plug-in (and all other storage-related plug-ins) for iManager require CIMOM connections for tasks that transmit sensitive information (such as a user name and password) between iManager and the _admin volume on the OES server you are managing. Typically, CIMOM is running, so this should be the normal condition when using the server. CIMOM connections use HTTPS for transferring data, which ensures that sensitive data is not exposed.

IMPORTANT:SFCB is automatically PAM-enabled for Linux User Management (LUM) as part of the OES installation. Users not enabled for LUM cannot use the CIM providers to manage OES. The user name that you use to log in to iManager when you manage a cluster and the BCC cluster must be a eDirectory user name that has been LUM-enabled.

For more information about the permissions and rights needed by the BCC Administrator user, see Section 4.8, eDirectory 9.2.1 and Section 5.3, Configuring a BCC Administrator User and Group.

If CIMOM is not currently running when you click OK or Finish for the task that sends the sensitive information, you get an error message explaining that the connection is not secure and that CIMOM must be running before you can perform the task.

IMPORTANT:If you receive file protocol errors, it might be because SFCB is not running.

You can use the rcsfcb command to help resolve CIMOM and SFCB issues:

To perform this task

At a command prompt, enter as the root user

To start SFCB service

rcsblim-sfcb start

To stop SFCB service

rcsblim-sfcb stop

To check SFCB service status

rcsblim-sfcb status

To restart SFCB service

rcsblim-sfcb restart
