Replication Checkpoints

Checkpoints enable administrators to check child machines are up-to-date in terms of policy updates and other infrastructure data (that is, user and machine details).

The CMS generates a checkpoint record and adds this to the replication queue, from where it is subsequently sent to all child machines. Each child machine then returns a checkpoint acknowledgment. This is a confirmation that the child machine has received all infrastructure updates sent prior to this latest checkpoint. Note that acknowledgments are fast-tracked back to the CMS to allow rapid diagnosis of your CA DataMinder deployment.

Checkpoints can be generated automatically, for example, at 01.00 am every day or after every 1,000 infrastructure updates. You can also manually generate checkpoints and configure how long checkpoints and their acknowledgment are retained in the CMS database.

How long are checkpoints retained?

By default, checkpoints and acknowledgments are retained in the CMS database for 60 days, but you can configure this in the CMS machine policy.

Automatic checkpoints

You can configure the CMS to generate checkpoints automatically, at regular intervals or after a specified number of infrastructure updates. To do this, or to disable automatic checkpoints, you edit the CMS machine policy.

Automatic checkpoints are assigned a checkpoint ID and description, both of which can be used when running a custom administration search for machines.

Automatic checkpoints are assigned one of two checkpoint descriptions:

• Scheduled: Specifies a regular checkpoint generated using the Checkpoint Time and Checkpoint Frequency machine policy settings.
• Triggered by update count threshold: Specifies a checkpoint generated by the Update Count Threshold machine policy setting.

Manual checkpoints

If required, you can manually set checkpoints. For example, you may want to send a custom checkpoint after making changes to your user hierarchy or after running a major Account Import job. To set a manual checkpoint:

1. Choose Tools, Generate Checkpoint.
2. In the resulting dialog, specify a description of the checkpoint and click Generate.

   A checkpoint ID appears in the dialog. The checkpoint ID can be copied to the Windows clipboard for use when running a custom administration search for machine.

3. Close the dialog.

Note: The description, along with the checkpoint ID, is stored in the Wgn3Checkpoint database table.
