Create an Oracle data source

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 checking for and limiting 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 information about how to automatically or manually add the IP address of the data transmission server to a whitelist or security group, see Add a whitelist.

Procedure

1. Log on to the ApsaraDB for OceanBase console.

2. In the left-side navigation pane, choose Data Transmission > Data Source Management.

3. In the Data Sources section, click New Data Source in the upper-right corner.

   

4. In the New Data Source dialog box, select Oracle for Data Source Type.

5. Configure the parameters. Select an instance type from the Instance Type drop-down list. The corresponding configuration section automatically appears.

   

   Instance type	Parameter	Description

   Instance type	Parameter	Description
   Self-Managed Database in VPC	VPC	Select the desired virtual private cloud (VPC) from the VPC drop-down list. You can also perform a fuzzy search.
   	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.
   Self-Managed Database with Public IP Address (containing all 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.
   	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.
   	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.
   	Remarks	The additional information about the data source.

6. Click Test Connection to verify the network connection between the data transmission service and the data source, as well as the validity of the username and password.

7. After the test is passed, click OK.
