Performing a Check Before Using a Real-Time Job
Before creating a real-time synchronization task in DataArts Migration, you must check the items listed in the following table to ensure that the environment meets the requirements of the task.
Item |
Description |
Preparation |
---|---|---|
Account and permissions of Huawei Cloud |
Prepare a HUAWEI ID. Create a user and authorize the user to use DataArts Migration.
NOTE:
|
See Registering a Huawei ID and Enabling Huawei Cloud Services. |
Real-time computing resource group |
You need to buy the compute resources required by the real-time migration task and associate them with the DataArts Studio workspaces you want to use. You are advised to configure an independent resource pool for DataArts Migration. |
See Buying a DataArts Migration Resource Group Incremental Package. See Associating a Real-Time Migration Resource Group with Workspaces. |
Databases |
Prepare the source and destination databases and the corresponding connection account permissions.
NOTE:
|
The required permissions vary depending on the link and database. For details, see Tutorials. |
Connections |
Create data connections in DataArts Studio Management Center.
NOTE:
|
For details, see Configuring DataArts Studio Data Connection Parameters. |
Network
NOTE:
Ensure that the round-trip time (RTT) between DataArts Migration and the destination database is less than 2 ms. Otherwise, the migration task performance will be affected. For example, if the destination database is far away from DataArts Migration (for example, the database is deployed outside the Chinese mainland and is connected to DataArts Migration in the Chinese mainland through a VPN), the RTT is much more than 2 ms, resulting in a migration delay. |
Databases are deployed in an on-premises IDC. |
Prepare the network by referring to Database Deployed in an On-premises IDC. |
Databases are deployed on another cloud. |
Prepare the network by referring to Database Deployed on Another Cloud. |
