Use Web ODC

This topic describes some basic operations for using Web ODC.

Create a user

Example: Create a user named ODCUSER1 in OceanBase Developer Center (ODC) as the administrator and grant the permissions of the system_admin role to the user.

1. Log in to Web ODC. In the left-side navigation pane of the project collaboration window, choose User Permissions > Users . On the Users tab, click Create User .

   

2. On the Create User page, complete the user and role settings.

   

   This parameter is optional. You can assign multiple roles to a user. Click the field. In the drop-down list, select the roles that you want to assign to all users that you have created. If no role is available, go to the Create Role page to create one.

3. Click Create .

Create a data source

Create an OceanBase data source

Example: Create an OceanBase MySQL data source in ODC.

1. Obtain the connection information or connection string of the data source instance. The connection string is in the format of mysql -h host name -P port number -u database username@tenant name#cluster name -D default database -p ' database password'. Here is an example:

   -hxxx.x.x.x -P8080 -uodc@mysql_tenant#odc_cluster -Dodc -p'******'
   

2. In the left-side navigation pane of the project collaboration window, choose Data Sources > Create Data Source > OceanBase MySQL .

   ODC supports the following OceanBase Database instance types:

   • OceanBase MySQL or OceanBase Oracle : a database instance that you build in your own environment.

   • OB Cloud MySQL or OB Cloud Oracle : a database instance on Alibaba Cloud.

   

3. In the Create Data Source panel, specify the following information.

   Note

   If you have obtained the connection string of the database, you can obtain the following information from the connection string or use the intelligent parsing tool provided on the tab to fill in the information.

   

   Parameter	Description
   Data Source Type	By default, the selected data source type is displayed.
   Intelligent Parsing	You can paste a connection string to the field. ODC automatically identifies the string and fills in the corresponding values.
   Endpoint	Host IP/Domain Name : the IP address of the server where the target database is located. Port : the port number of the server where the target database is located. Cluster : the name of the cluster where the target database is located. This parameter is not required for logical databases. Tenant : the name of the tenant in which the target database is located. This parameter is not required for logical databases. Note If the tenant is created on Alibaba Cloud or in OCP, you can obtain the host name and port number from the information page of the tenant in which the target database is located. The default port is 8989.
   Database Account	Database User Name : the username of an account created in the tenant. In MySQL mode, this account must have the privilege to access the default database. Database Password : the password of the account created in the tenant. You can click Test Connection next to the password field to test whether you can connect to the target database. Note An error will be returned if the configurations such as the username, password, or network settings are invalid. You can only connect to a database in the current tenant. Otherwise, a test failure error will be returned. Before you save the configurations, you can click Test Connection to test the database connection. If the database username and password are correct, the system returns a message indicating that the connection succeeded. In ODC V4.0.0 and later, you can save the connection without setting the database account and password.
   Environment	You can select an environment type as needed. Valid values: dev , sit , and prod .

   Note

   For more information about data source configurations, see Manage data sources.

4. Click OK in the lower-right corner of the panel. In the dialog box that appears, enter the name of the data source.
