 For example, if your database is hosted on AWS, you will need to use the connection format provided in this link: [AWS conection string](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ConnectToOracleInstance.SQLPlus.html). Therefore, a valid example connection string would be as follows:
 
-  `TEST_USER@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=url.amazonaws.com)(PORT=1521))(CONNECT_DATA=(SID=orcl)))` 
+  `TEST_USER/PASSWORD@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=url.amazonaws.com)(PORT=1521))(CONNECT_DATA=(SID=orcl)))` 
 
 The link contains detailed instructions on how to connect to an Oracle instance on AWS using SQL\*Plus or SQLcl. It provides the necessary format for specifying the connection details, such as the hostname, port, and SID. By following the instructions in the link, you will be able to establish a successful connection to your Oracle database hosted on AWS.

 You are now ready to proceed with executing the DLL code generation using the files found in the "bin" and "script" folders.
 
 In the "bin" folder, you will find the bash scripts for Unix/Linux environments or the batch scripts for Windows. These scripts are designed to facilitate the DLL code generation process, ensuring compatibility across different operating systems:
