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.

Table 1 Check items

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:
  • Use the DataArts Studio starter version or a more advanced version.
  • If you use a federated account, you need to configure an agency for submitting jobs. For details, see Configuring Scheduling Identities

See Registering a Huawei ID and Enabling Huawei Cloud Services.

See Authorizing the Use of Real-Time Data Migration.

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:
  • You are advised to create an independent database account for the connection of the migration task to prevent task failures caused by account modification.
  • After changing the account passwords for the source or destination databases, modify the connection information in the migration task as soon as possible to prevent automatic retry after a task failure. Automatic retries will lock the database accounts.

The required permissions vary depending on the link and database. For details, see Tutorials.

Connections

Create data connections in DataArts Studio Management Center.

NOTE:
  • When creating a data connection, you must select DataArts Migration for Applicable Modules.
  • The agent used in a data connection is a CDM cluster. You must upgrade the cluster to version 24.4.0B030 or a later version to meet function and feature requirements. For details, contact the customer service or technical support.

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.

Databases are deployed on Huawei Cloud.
