+### Whole Database, Multiple Schemas, Multiple Tables Migration
+
+Oracle Extract Node supports the whole database, multiple schemas, multiple
tables migration function. When you enable this function, Oracle Extract Node
will compress the physical field of the table into a special meta field
'data_canal' in the format of 'canal json'.
+
+config options:
+
+| Option | Required | Default | Type | Description |
+| ---| ---| ---| ---| ---|
+|source.multiple.enable|optional| false|String|Specify
`'source.multiple.enable' = 'true'` to enable the whole database, multiple
schemas, multiple tables migration function |
+|schema-name|required|(none)|String| Schema name of the Oracle database to
monitor. If you want to capture multiple schemas, you can use commas to
separate them. For example: `'schema-name' = 'SCHEMA1,SCHEMA2'` |
+|table-name| required | (none) |String| Table name of the Oracle database to
monitor. If you want to capture multiple tables, you can use commas to separate
them. For example: `'table-name' = 'SCHEMA1.TB.*, SCHEMA2.TB1'`|
+
+The CREATE TABLE example demonstrates the syntax of this function:
+
+```sql
+CREATE TABLE node(
+ data STRING METADATA FROM 'meta.data_canal' VIRTUAL)
+ WITH (
+ 'connector' = 'oracle-cdc-inlong',
+ 'hostname' = 'localhost',
+ 'port' = '1521',
+ 'username' = 'flinkuser',
+ 'password' = 'flinkpw',
+ 'database-name' = 'XE',
+ 'schema-name' = 'inventory',
+ 'table-name' = 'inventory..*',
+ 'source.multiple.enable' = 'true'
+)
