Viewing Replication Channel Information

The channel state shows that a replication channel is enabled and active, or else indicates the reason why replication is not currently in progress. The channel details give further information about a replication channel.

Using the Console

Use the Console to view the state of an inbound replication channel and see more details about it.

  1. Open the navigation menu and select Databases. Under HeatWave MySQL, click Channels.
  2. Choose your compartment from the List scope.
  3. In the list of channels, check the icon in the State column to see the state of each channel. The color of the icon and the associated text show the state of the channel. See Channel States.
  4. To see the Channel details page, click the name of the channel you want to view details for. See Channel Details.

Channel States

Check the State column to view the state of the replication channel.

Table 13-2 Channel States

Channel State Description
Deleted The channel has been deleted and is no longer available.
Creating The channel is being created. Provisioning can take several minutes. The channel is not yet replicating data from the source to the target.
Deleting The channel is being deleted.
Inactive The channel is not replicating because the user has disabled it.
Needs Attention This status is displayed for the following reasons:
  • The channel is not replicating due to an error. The Details column on the Channels page explains why the channel needs attention.
  • The target DB system is INACTIVE, that is, the channel is created or updated while the DB system is in INACTIVE state. Pending actions are applied if the DB system is started.
Updating A channel operation is going on.
Active The channel is running and replicating successfully.
The DB system operations affect the channel state. See Overview of Inbound Replication.
