Setting advanced properties

In the Advanced tab, you can set the following parameters:

  • Select one of the following Check for changes options:
    • Periodically: When this option is selected, Replicate checks for changes according to the Delta extraction interval.

      Information noteThe interval will start after each "round". A round can be defined as the time it takes for Replicate to read the changes from the source tables, and send them to the target (as a single transaction). The length of a round varies according to the number of tables and changes. So if you specify an interval of 10 minutes and a round takes 4 minutes, then the actual time between checking for changes will be 14 minutes.
    • On initial run and then as scheduled: When this option is selected, to continue capturing changes after the initial task run, you need to schedule the task to run according to your needs.

      Information noteThis option is only relevant if the interval between the CDC cycles is 24 hours or more.

      For information on scheduling tasks, see Scheduling jobs.

  • Delta extraction interval: Defines how frequently the deltas are extracted from your system.

    • The default is every 60 seconds.
    • Setting the value to 0 means that all the datasets of the task will run only one delta/initial load and then the task will stop automatically.
  • Max records per request: The size of the data package in records. This value can be adjusted according to your network and system capabilities. A background job is started for paging, and the data is cached in the operational delta queue. Using the odata.maxpagesize value, you can specify the quantity of packages to be retrieved from the delta queue. 

    For more information, see Using the OData Service for Extracting ODP Data.

  • SAP services URI: The URI for accessing your SAP services. The default value is /sap/opu/odata/SAP/.

    The Internal Parameters dialog box opens.

  2. In the edit box, type the name of the parameter you need to add and then click it.
  3. The parameter is added to the table below the search box with its default value.
  4. Change the default value as required.
  5. To reset the parameter value to its default, click the "Restore default value" icon at the end of the row.

More options

These options are not exposed in the UI as they are only relevant to specific versions or environments. Consequently, do not set these options unless explicitly instructed to do so by Qlik Support or product documentation.

To set an option, simply copy the option into the Add feature name field and click Add. Then set the value or enable the option according to the instructions you received.
