About StartReplicationTask

Starts the replication task.

For more information about DMS tasks, see Working with Migration Tasks in the Database Migration Service User Guide.

Method Signature

IMPORTING

Required arguments:

IV_REPLICATIONTASKARN TYPE /AWS1/DMGSTRING /AWS1/DMGSTRING

The Amazon Resource Name (ARN) of the replication task to be started.

IV_STARTREPLICATIONTASKTYPE TYPE /AWS1/DMGSTRTREPLTASKTYPEVALUE /AWS1/DMGSTRTREPLTASKTYPEVALUE

The type of replication task to start.

When the migration type is full-load or full-load-and-cdc, the only valid value for the first run of the task is start-replication. This option will start the migration.

You can also use ReloadTables to reload specific tables that failed during migration instead of restarting the task.

The resume-processing option isn't applicable for a full-load task, because you can't resume partially loaded tables during the full load phase.

For a full-load-and-cdc task, DMS migrates table data, and then applies data changes that occur on the source. To load all the tables again, and start capturing source changes, use reload-target. Otherwise use resume-processing, to replicate the changes from the last stop position.

Optional arguments:

IV_CDCSTARTTIME TYPE /AWS1/DMGTSTAMP /AWS1/DMGTSTAMP

Indicates the start time for a change data capture (CDC) operation. Use either CdcStartTime or CdcStartPosition to specify when you want a CDC operation to start. Specifying both values results in an error.

Timestamp Example: --cdc-start-time “2018-03-08T12:12:12”

IV_CDCSTARTPOSITION TYPE /AWS1/DMGSTRING /AWS1/DMGSTRING

Indicates when you want a change data capture (CDC) operation to start. Use either CdcStartPosition or CdcStartTime to specify when you want a CDC operation to start. Specifying both values results in an error.

The value can be in date, checkpoint, or LSN/SCN format.

Date Example: --cdc-start-position “2018-03-08T12:12:12”

Checkpoint Example: --cdc-start-position "checkpoint:V1#27#mysql-bin-changelog.157832:1975:-1:2002:677883278264080:mysql-bin-changelog.157832:1876#0#0#*#0#93"

LSN Example: --cdc-start-position “mysql-bin-changelog.000024:373”

When you use this task setting with a source PostgreSQL database, a logical replication slot should already be created and associated with the source endpoint. You can verify this by setting the slotName extra connection attribute to the name of this logical replication slot. For more information, see Extra Connection Attributes When Using PostgreSQL as a Source for DMS.

IV_CDCSTOPPOSITION TYPE /AWS1/DMGSTRING /AWS1/DMGSTRING

Indicates when you want a change data capture (CDC) operation to stop. The value can be either server time or commit time.

Server time example: --cdc-stop-position “server_time:2018-02-09T12:12:12”

Commit time example: --cdc-stop-position “commit_time:2018-02-09T12:12:12“
