The Issue with Godror and Oracle ACLs

Oct 13, 2025 by wbrum.org 58 views

Introduction

Oracle Database is a powerful and widely-used relational database management system that supports various programming languages, including Go. The godror driver is a popular Go package that provides a simple and efficient way to connect to Oracle databases. However, when working with Oracle databases that have Access Control Lists (ACLs) that include the program name, developers may encounter issues with the godror driver. In this article, we will explore why the godror driver makes Oracle ACL recognize the program name as main@<hostname> (TNS V1-V3).

Understanding Oracle ACLs

Oracle ACLs are used to control access to the database by specifying the program name, IP address, and other attributes. When a client connects to the database, the Oracle server checks the ACL to determine whether the client is allowed to access the database. The program name is a critical attribute in the ACL, as it identifies the client application that is connecting to the database.

The Issue with Godror and Oracle ACLs

When using the godror driver to connect to an Oracle database, the program name is recognized as main@<hostname> (TNS V1-V3). This can cause issues when the Oracle database has an ACL that includes the program name, as the godror driver may not be able to connect to the database. The issue is not specific to the godror driver, but rather a result of how the Oracle database handles the program name in the ACL.

Why Oracle Recognizes the Program Name as `main@<hostname> (TNS V1-V3)`

Oracle recognizes the program name as main@<hostname> (TNS V1-V3) because of the way the godror driver establishes a connection to the database. When the godror driver connects to the Oracle database, it uses the TNS (Transparent Network Substrate) protocol to establish a connection. The TNS protocol is a proprietary protocol developed by Oracle that allows clients to connect to the database using a variety of protocols, including TCP/IP and UDP.

When the godror driver uses the TNS protocol to connect to the database, it includes the program name in the connection string. The program name is included in the form of main@<hostname>, where <hostname> is the hostname of the machine running the godror driver. The (TNS V1-V3) part of the program name indicates that the connection is using the TNS protocol version 1 to 3.

The Impact of the Program Name on Oracle ACLs

The program name main@<hostname> (TNS V1-V3) can have a significant impact on Oracle ACLs. When the Oracle database checks the ACL to determine whether the client is allowed to access the database, it will check the program name to ensure that it matches the program name specified in the ACL. If the program name does not match, the client will be denied access to the database.

Workarounds for the Issue

There are several workarounds for the issue of the godror driver making Oracle ACL recognize the program name as main@<hostname> (TNS V1-V3). One approach is to modify the Oracle ACL to include the program name in the form of main@<hostname> (TNS V1-V3). This will ensure that the godror driver is able to connect to the database without any issues.

Another approach is to use a different driver that does not include the program name in the connection string. However, this may require significant changes to the application code and may not be feasible in all cases.

Conclusion

In conclusion, the godror driver makes Oracle ACL recognize the program name as main@<hostname> (TNS V1-V3) because of the way the driver establishes a connection to the database using the TNS protocol. This can cause issues when the Oracle database has an ACL that includes the program name. However, there are several workarounds for the issue, including modifying the Oracle ACL and using a different driver.

Additional Considerations

Kubernetes and Oracle Databases

When working with Kubernetes and Oracle databases, it is essential to consider the program name and how it will be recognized by the Oracle database. The godror driver may not be able to connect to the database if the program name does not match the program name specified in the ACL.

Go and Oracle Databases

The godror driver is a popular Go package that provides a simple and efficient way to connect to Oracle databases. However, the driver may not be able to connect to the database if the program name does not match the program name specified in the ACL.

Oracle Database Security

Oracle database security is a critical aspect of any application that uses the Oracle database. The ACL is a critical component of Oracle database security, as it controls access to the database based on the program name, IP address, and other attributes.

Best Practices for Working with Oracle Databases

When working with Oracle databases, it is essential to follow best practices to ensure that the application is able to connect to the database without any issues. This includes modifying the Oracle ACL to include the program name in the form of main@<hostname> (TNS V1-V3) and using a different driver that does not include the program name in the connection string.
