You must configure data sources before you create a data migration or synchronization task. This topic describes how to create an Oracle data source by using the data transmission service.
Security risks
You can choose to automatically or manually add public CIDR blocks for the data transmission service, but security risks exist. Your use of the data transmission service indicates that you have understood and acknowledged the possible security risks. You must take basic security protection measures, such as setting a complex password for your account, limiting the open port numbers of CIDR blocks, enabling authentication for communication among internal APIs, and regularly check for and limit CIDR blocks that are not required.
The data transmission service will add or delete the CIDR blocks automatically added to a whitelist or security group based on business needs and security risks. Do not use the CIDR blocks in a whitelist or security group for business needs other than the data transmission service. If you use such CIDR blocks for other business needs, the issues thus incurred are beyond the guarantee scope of the SLA of the data transmission service. For more information about how to add an IP address to a whitelist or security group for the data transmission service, see Add a whitelist.
Procedure
Log on to the ApsaraDB for OceanBase console.
In the left-side navigation pane, choose Data Transmission > Data Source Management.
In the Data Sources section, click New Data Source in the upper-right corner.
In the New Data Source dialog box, select Oracle for Data Source Type.
Configure the parameters. Select an instance type from the Instance Type drop-down list. The corresponding configuration section automatically appears.
Instance Type
Parameter
Description
Self-Managed Database in VPC
VPC
Select the desired virtual private cloud (VPC) from the VPC drop-down list.
Host IP Address
The IP address of the host where the database is located.
Port
The port number of the host where the database is located.
Database Gateway
Gateway Name
Select the name of the target database gateway from the Gateway Name drop-down list.
Database Instance
Select the target database instance from the Database Instance drop-down list.
Self-Managed Database with Public IP Address
Host IP Address
The IP address of the host where the database is located.
Port
The port number of the host where the database is located.
Common parameters
Data Source Identifier
We recommend that you set it to a combination of digits and letters. It must not contain any spaces and cannot exceed 32 characters in length.
Cross Alibaba Cloud Account
The data transmission service allows you to configure a task to migrate or synchronize data between instances under different Alibaba Cloud accounts.
You can choose whether to select this option based on business needs. If you select this option, enter the Alibaba Cloud account of the target instance. If you do not have permissions on this Alibaba Cloud account, request for authorization first. For more information, see Apply for cross-account authorization.
ImportantThis parameter is not displayed when Self-Managed Database with Public IP Address is selected as the instance type.
Service Name
The service name of the Oracle database.
Username
The username of the Oracle database for data migration or synchronization.
We recommend that you create a separate database user for the migration or synchronization task.
Password
The password of the database user.
Schema Name
The schema name of the Oracle database.
NoteIf this parameter is specified, you can select migration or synchronization objects only in the specified schema when the data source serves as the source of a data migration or synchronization task.
If this parameter is not specified, you can select all accessible schemas as the migration or synchronization objects.
Remarks
Additional information about the data source.
Click Test Connection to verify the network connection between the data transmission system and the data source, as well as the validity of the username and password.
After the test is passed, click OK.
