Category | Configuration | Description |
None | Task Name | The name of the DTS task. DTS automatically generates a task name. We recommend that you specify an informative name that makes it easy to identify the task. You do not need to specify a unique task name. |
Source Database Information | Select Existing Connection | The instance that you want to use. You can choose whether to use an existing instance based on your business requirements. If you select an existing instance, DTS automatically populates the parameters for the database. If you do not use an existing instance, you must configure the database information below.
|
Database Type | Select MongoDB. |
Access Method | Select Cloud Instance. |
Instance Region | Select the region where the source Cloud Database MongoDB Edition resides. |
Replicate Data Across Alibaba Cloud Accounts | In this example, a database instance of the current Alibaba Cloud account is used. Select No. |
Architecture Type | For MongoDB with standalone instance architecture, select Replica Set Architecture. Replica Set Architecture: Achieves high availability and read/write splitting by deploying multiple nodes. For more information, see Replica set architecture. Sharded Cluster Architecture: Provides three components: Mongos, Shard, and ConfigServer. You can freely choose the number and configuration of Mongos and Shard. For more information, see Sharded cluster architecture.
|
Migration Method | When the source database is a standalone instance architecture of MongoDB, incremental migration is not supported. Keep the default Oplog. |
Instance ID | Select the instance ID of the source Cloud Database MongoDB Edition. |
Authentication Database Name | Enter the name of the database to which the database account of the source Cloud Database MongoDB Edition instance belongs. If it has not been modified, the default is admin. |
Database Account | Enter the database account of the source Cloud Database MongoDB Edition. For permission requirements, see Permissions required for database accounts. |
Database Password | The password that is used to access the database instance. |
Encryption | Specifies whether to encrypt the connection to the source database. You can select Non-encrypted, SSL-encrypted, or Mongo Atlas SSL based on your business requirements. The options available for the Encryption parameter are determined by the values selected for the Access Method and Architecture parameters. The options displayed in the DTS console prevail. Note If the Architecture parameter is set to Sharded Cluster, and the Migration Method parameter is set to Oplog for the ApsaraDB for MongoDB database, the Encryption parameter SSL-encrypted is unavailable. If the source database is a self-managed MongoDB database that uses the Replica Set architecture, the Access Method parameter is not set to Alibaba Cloud Instance, and the Encryption parameter is set to SSL-encrypted, you can upload a certification authority (CA) certificate to verify the connection to the source database.
|
Destination Database | Select Existing Connection | The instance that you want to use. You can choose whether to use an existing instance based on your business requirements. If you select an existing instance, DTS automatically populates the parameters for the database. If you do not use an existing instance, you must configure the database information below.
|
Database Type | Select MongoDB. |
Access Method | Select Cloud Instance. |
Instance Region | Select the region where the destination Cloud Database MongoDB Edition resides. |
Replicate Data Across Alibaba Cloud Accounts | In this example, a database instance of the current Alibaba Cloud account is used. Select No. |
Architecture Type | Select the architecture based on your business needs. Valid values: Replica Set Architecture: Achieves high availability and read/write splitting by deploying multiple nodes. For more information, see Replica set architecture. Sharded Cluster Architecture: Provides three components: Mongos, Shard, and ConfigServer. You can freely choose the number and configuration of Mongos and Shard. For more information, see Sharded cluster architecture.
|
Instance ID | Select the instance ID of the destination Cloud Database MongoDB Edition. |
Authentication Database Name | Enter the name of the database to which the database account of the destination Cloud Database MongoDB Edition belongs. If it has not been modified, the default is admin. |
Database Account | Enter the database account of the destination Cloud Database MongoDB Edition. For permission requirements, see Permissions required for database accounts. |
Database Password | The password that is used to access the database instance. |
Encryption | Specifies whether to encrypt the connection to the destination database. You can select Non-encrypted, SSL-encrypted, or Mongo Atlas SSL based on your business requirements. The options available for the Encryption parameter are determined by the values selected for the Access Method and Architecture parameters. The options displayed in the DTS console prevail. Note If the destination database is an ApsaraDB for MongoDB instance and the Architecture parameter is set to Sharded Cluster, the Encryption parameter SSL-encrypted is unavailable. If the destination database is a self-managed MongoDB database that uses the Replica Set architecture, the Access Method parameter is not set to Alibaba Cloud Instance, and the Encryption parameter is set to SSL-encrypted, you can upload a CA certificate to verify the connection to the destination database.
