Setting advanced connection properties

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

• Automatically enable full row logging: Full Row Logging is required for CDC. Select this option to automatically enable Full Row Logging for the tables to be replicated. To automatically enable Full Row Logging, the user specified in the General tab must have administrative privileges on the IBM Informix database.

  Information note

  DDL events are not captured during CDC. To perform DDL operations on source tables in a Replicate CDC task:

  1. Stop the Replicate task.

  2. Disable Full Row Logging for the relevant tables as in the following example:

     execute function syscdcv1:IBM Informix.cdc_set_fullrowlogging('sysuser:IBM Informix.employees_table', 0)

  3. Perform the DDL operation(s).

  4. If the Automatically enable full row logging option is not selected, manually enable Full Row Logging for the relevant tables.

  5. Start the Replicate task.

  6. Reload the relevant tables or perform a Full Load.

• Max bytes per read: Specify the maximum number of bytes to read each time the log is accessed. If you encounter performance issues, adjusting this number may help.

Internal parameters

Internal parameters are parameters that are not exposed in the UI. You should only use them if instructed by Qlik Support.

To add internal Qlik Replicate parameters:

1. Click the Internal Parameters link.

   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.

Settings summary

You can view a summary of your settings by clicking the Setting Summary link. This is useful if you need to send a summary of your settings to Qlik Support.
