Connection Steps

Please follow the steps below to connect to the OceanBase data source.

1. Click "New Data Connection" in the upper right corner of the data connection page.

2. Select the OceanBase data source from the list of data source types.

3. Fill in the required parameters for the data source connection as prompted.

   Connection Configuration Information Description

   Field	Description
   Name	The name of the connection. Required and unique within the user
   Host Address	The address of the database. If the URL field is filled in, the URL will take precedence
   Port	The port of the database. If the URL field is filled in, the URL will take precedence
   Username	The username for the database
   Password	The password for the database
   Database	The name of the database
   Max Connections	The maximum number of connections in the connection pool
   ssl	Whether to use SSL connection
   Prefer using database comment as dataset title	Whether to display the table name or the table comment as the title. When enabled, shows the title; when disabled, shows the table comment
   URL	The JDBC URL of the database
   Transaction isolation level for read operations	This setting only affects reading data; writing data still uses the default isolation level
   Hierarchical loading of schema and tables	Default is off. When enabled, schemas and tables are loaded hierarchically; only schemas are loaded during connection, and you need to click the schema to load the tables under it
   Query timeout (seconds)	Default is 600. When the data volume is large, you can appropriately increase the timeout
   Allow write operations	Indicates that this connection can be selected as an output connection in Data Integration and Batch Sync. You must have write permission to the database and pass verification before configuring this parameter.
   Support uploading files to specified path	Indicates the database name where the generated table will be stored when creating a local file dataset. You must have write permission to the database and pass verification before configuring this parameter.
   Show only tables under the specified database/schema	When this option is selected and the database field is not empty, only tables under that db will be displayed

4. After filling in the parameters, click the Validate button to get the validation result (this checks the connectivity between HENGSHI SENSE and the configured data connection; you cannot add the connection if validation fails).

5. After validation passes, Allow write operations and Support uploading files to specified path will be enabled and can be optionally turned on.

6. Click Execute Preset Code to pop up the preset code for this data source, then click the execute button.

7. Click the Add button to add the OceanBase connection.

Please note

1. Parameters marked with * are required; others are optional.
