从 boto3 脚本创建 AWS DMS 任务的问题

问题描述

使用以下 python boto3 脚本创建 AWS DMS 任务并启动复制任务，但出现以下错误：

错误：

botocore.errorfactory.InvalidResourceStateFault: An error occurred (InvalidResourceStateFault) when calling the StartReplicationTask operation: Replication Task cannot be started,invalid state

Python 脚本：

#!/usr/bin/python
import boto3
client_dms = boto3.client('dms')

#Create a replication DMS task
response = client_dms.create_replication_task(
    ReplicationTaskIdentifier='test-new1',ResourceIdentifier='test-new',ReplicationInstanceArn='arn:aws:dms:us-east-1:xxxxxxxxxx:rep:test1',SourceEndpointArn='arn:aws:dms:us-east-1:xxxxxxxxxx:endpoint:source',TargetEndpointArn='arn:aws:dms:us-east-1:xxxxxxxxxx:endpoint:target',MigrationType='full-load',TableMappings='{\n \"TableMappings\": [\n {\n \"Type\": \"Include\",\n \"SourceSchema\": \"test\",\n \"SourceTable\": \"table_name\"\n}\n ]\n}\n\n'
)

#Start the task from DMS
response = client_dms.start_replication_task(
    ReplicationTaskArn='arn:aws:dms:us-east-1:xxxxxxxxxx:task:test-new',StartReplicationTaskType='start-replication'
)

解决方法

可能必须使用 waiter 才能完成任务：

• ReplicationTaskReady

在您可以对其执行其他操作之前。
