Resuming a Channel
When an inbound replication channel is in the Needs Attention state, fix the error then resume the channel to restart replication. The Details column on the Channels page explains why a replication channel needs attention.
The Needs Attention state may also be displayed because the DB system is in
INACTIVE
state. In that case, replication cannot restart until the
DB system is active.
- Using the Console
- Using the REST API, run the ResumeChannel operation.
Resetting a Channel
Resetting an inbound replication channel removes all data on the channel,
except the channel configuration. It is equivalent to RESET REPLICA ALL FOR
CHANNEL
. When there is an unrecoverable issue, the reset operation clears the
records associated with replication so that the channel can have a clean start.
The target DB system drops its position in the source binary log, clears the replication metadata repositories, deletes the relay log files, and starts a new relay log file.
- Using the Console
- Using the REST API, run the ResetChannel operation.
Using the Console
Use the reset operation when there is an unrecoverable error in replication. Only the channel configuration is retained, and the records are removed.
To reset an inbound replication channel, it must be inactive. You cannot reset an active channel.
- On the Channels list page, find the channel that you want to work with. If you need help finding the list page or the channel, see Listing Channels - Using the Console.
