7.5.1 Disabling or Enabling a Channel

Disabling a channel pauses the replication and enabling a channel resumes the replication.

Note:

If the source server contains existing data, it is necessary to copy over this data to the target server before enabling the channel and starting replication for the first time. For more information, see Choosing a Method for Data Snapshots and Importing Data.

To disable or enable a Channel:

1. In the HeatWave Console, select the HeatWave MySQL tab, and then click Channels to open the Channels page.
2. In the list of channels, find the channel you want to disable or enable.
3. To disable an active channel, do one of the following:
   • Select the row of the channel to highlight it, and click the Disable button.
   • Click the name of the channel to open the Channel Details page. Click the Disable button.

   The Disable MySQL Channel dialog is displayed. Click Disable to confirm.

   The state of the channel changes to Updating and then to Inactive.

4. To enable an inactive channel, do one of the following:
   • Select the row of the channel to highlight it, and click the Enable button.
   • Click the name of the channel to open the Channel Details page. Click the Enable button.

   The Enable MySQL Channel dialog is displayed. Click Enable to confirm.

   The state of the channel changes to Updating and then to Active. The final state becomes Needs Attention if it encounters any error and replication cannot start.
