Enabling and configuring incremental replication

You can incrementally replicate the IBM® Security Guardium® Key Lifecycle Manager critical data from the master server to the clone servers. With incremental replication, the master server updates the clone servers with the delta changes frequently. You can use the graphical user interface or REST interface to enable and schedule incremental replication.

Before you begin

Ensure that full replication is already configured on the master server. For more information, see Enabling and configuring full replication.

About this task

Incremental replication needs to be configured on the master server. No configuration is required on the clone server.

Procedure

  • Using graphical user interface
    1. Log in to the graphical user interface.
    2. Click Administration > Replication.
    3. Ensure that Master role is selected.
    4. Click the Advanced Properties tab.
    5. In the Replication Scheduler Section, select the Incremental replication frequency check box.
    6. Optional: Specify the frequency (in seconds) at which you want the incremental replication operation to run.
      By default, the incremental replication operation runs every 60 seconds, which is one minute.
    7. Click Start Replication Server.
    8. Click OK.
  • Using REST APIs
    1. Open a REST client.
    2. Obtain a unique user authentication identifier to access IBM Security Guardium Key Lifecycle Manager REST services. For more information about the authentication process, see Authentication process for REST services.
    3. Run Update Replication Config Property REST Service to enable incremental replication.
      For example:
      PUT https://localhost:<port>/SKLM/rest/v1/replicationConfigProperties
      {"replication.Incremental.Enable": "true"}
    4. Optional: To modify the default frequency (60 seconds) of the incremental replication, run Update Replication Config Property REST Service and provide the frequency (in seconds) at which you want the incremental replication operation to run.
      For example:
      PUT https://localhost:<port>/SKLM/rest/v1/replicationConfigProperties
      {"replication.Incremental.CheckFrequency": "120"}
    5. Start Replication server.

Results

Incremental replication is enabled and configured. You can immediately run the operation by clicking Replicate Now. Otherwise, the operation runs based on the value given in the Incremental replication frequency field. The operation runs until you disable it.
