Managing CMDB synchronization


After you create the services by using the service blueprints, the topology data from different data sources must be synchronized with BMC Helix CMDB for normalizing and reconciling the data before it can be used by other consuming applications such as BMC Helix ITSM applications. 

Use the CMDB Sync feature in BMC Helix Service Modeling to synchronize these services data with BMC Helix CMDB

You must make sure that your BMC Helix CMDB is connected with BMC Helix Discovery (DSM only) through by using the CMDB Sync page in BMC Helix Service Modeling. 

The CMDB Sync page displays all configured CMDB Sync connections and provides the following controls:

  • Global actions  To perform tasks on the CMDB process as an entity and effective overall connections.

You can perform additional configuration and management tasks on individual CMDB Sync connections from the Manage CMDB Connection page in BMC Helix Discovery (DSM Only).

For information about performing these additional configurations, see Managing a CMDB sync connectionin the BMC Helix Discovery online documentation. 

Understating a CMDB Sync connection status

Each connection pane is color-coded to show its state, and an informational message on the state is included in the colored section.

The following table lists the color codes and their meaning:

Color code

Description

Green 

Connection is up and running.

Yellow 

The server has errors.

Blue

The connection has been manually paused or a blackout window is in operation.

Red

The server is unreachable, credentials are incorrect, or an unexpected connection error exists.

Grey

Connection disabled.


Each connection pane also provides the following information about the connection:

  • Name  A link to the connection page. 
    For information about managing connections, see Managing a CMDB sync connection.

  • Continuous sync status Status displayed as On or Off.
  • Network Address — The address of the BMC Helix CMDB server.
  • Dataset The CMDB dataset that the connection is syncing into.
  • Device nodes Counts of nodes inserted, updated, and deleted.
    This count can be reset by using the Actions button.
  • Data model The data model in use for the connection.
  • Currently processing Whether any nodes are currently being synced.
  • Devices in queue The number of devices that are currently being queued.

Performing tasks on all CMDB sync connections

The following tasks are performed on all CMDB sync connections:

Task

Description

Enabling and disabling continuous sync

Synchronization can be configured to run in a continuous mode. When BMC Helix Discovery completes its scan for a device, the data corresponding to it is queued for synchronization with the CMDB. Alternatively, synchronization can be manually launched from the browsing interface for one or more devices. The following options are available in the Global Actions menu:

  • Continuous Sync On
  • Continuous Sync Off

Pausing and resuming sync

Synchronization can be paused. Newly discovered or updated nodes and deletions are still added to the sync queues but not processed until synchronization is resumed. The following options are available in the Global Actions menu:

  • Pause Sync
  • Resume Sync

Enabling and disabling sync

Disabling sync means that newly discovered or updated nodes and deletions will no longer be added to the sync queues, though this does not prevent the CMDB target from being contacted. The following options are available in the Global Actions menu:

  • Disable Sync
  • Enable Sync


Performing tasks on individual CMDB sync connections

The following tasks are available from the Actions list for each CMDB sync connection:

Task

Description

Edit

Edit the connection details.

This opens the Manage CMDB Connection page with the Details tab displayed. You can also access it by clicking the connection name link.

Delete

Delete the connection.

You are prompted for confirmation.

Continuous Sync On/Continuous Sync Off

Turn continuous sync on or off.

Pause Sync/Resume Sync

Pause or resume sync.

Enable Sync/Disable Sync

Enable or disable sync.

Reset Counters

Reset the counts of nodes inserted, uploaded, and deleted for this connection.
