+We recommend that you configure a Db2 connector by using a Glue connections object. To do this, set the `glue_connection` environment variable of the Db2 connector Lambda to the name of the Glue connection to use.
+
+**Glue connections properties**
+
+Use the following command to get the schema for a Glue connection object. This schema contains all the parameters that you can use to control your connection.
+    
+    
+    aws glue describe-connection-type --connection-type DB2
+
+**Lambda environment properties**
+
+  * glue_connection – Specifies the name of the Glue connection associated with the federated connector. 
+
+  * **casing_mode** – (Optional) Specifies how to handle casing for schema and table names. The `casing_mode` parameter uses the following values to specify the behavior of casing:
+
+    * **none** – Do not change case of the given schema and table names. This is the default for connectors that have an associated glue connection. 
+
+    * **upper** – Upper case all given schema and table names.
+
+    * **lower** – Lower case all given schema and table names.
+
+
+
+
+###### Note
+
+  * All connectors that use Glue connections must use AWS Secrets Manager to store credentials.
+
+  * The Db2 connector created using Glue connections does not support the use of a multiplexing handler.
+
+  * The Db2 connector created using Glue connections only supports `ConnectionSchemaVersion` 2.
