Oracle ISV

What is the difference between Oracle ESL and ASFU?

Difference between Oracle ESL and ASFU:

  • ESL (Embedded Software License):
    • Highly restrictive.
    • For ISVs embedding Oracle in applications.
    • End users can’t directly access Oracle software.
  • ASFU (Application Specific Full Use):
    • Less restrictive than ESL.
    • Specific to particular applications.
    • More flexibility in software access and use.

What is the Oracle ESL License

Oracle ESL (Embedded Software License) is a specialized license designed for independent software vendors (ISVs) who incorporate Oracle software components into their applications.

This highly restrictive license allows ISVs to package and resell Oracle software with their solutions. The primary features of Oracle ESL include:

  • Packaging and Reselling: ISVs can bundle and resell Oracle software with their applications.
  • Restrictions: The software can only be used for the specific application package and cannot be used for third-party applications.
  • No Direct Access: End users cannot directly access or modify the Oracle software.
  • No Maintenance Requirement: Unlike other Oracle licenses, there’s no obligation to maintain technical support for Oracle ESL licenses.

What is an Oracle ASFU License

The article did not describe the Oracle ASFU (Application Specific Full Use) License.

However, based on general knowledge, ASFU licenses are designed for specific applications and are more restrictive than standard licenses. They are typically used when an ISV wants to embed an Oracle product into their application.

Differences between Oracle ESL and ASFU License

  • Usage: While both are for embedding Oracle software, ESL is more restrictive than ASFU.
  • Maintenance: ESL licenses do not require maintenance of Oracle technical support, whereas ASFU might.
  • Access: End users cannot directly access Oracle software under ESL, while ASFU might have different terms.

How to choose which Oracle ISV model is best, ESL or ASFU

Choosing between ESL and ASFU depends on the specific needs of the ISV and their application:

  • Application Integration: If the Oracle software needs to be deeply integrated and hidden from the end user, ESL might be more appropriate.
  • Flexibility: If there’s a need for more flexibility and less restriction, ASFU might be a better choice.
  • Cost: ESL offers a significant discount, which might make it more cost-effective for some ISVs.


What is Oracle ESL?

It’s a highly restrictive license for ISVs embedding Oracle software in their applications.

How is ASFU different from ESL?

ASFU is less restrictive and might offer more software access and modification flexibility.

Can end users access Oracle software under ESL?

No, all interactions must go through the ISV’s application interface.

Do I need to maintain technical support for ESL licenses?

There’s no obligation to maintain technical support for Oracle ESL licenses.

Which license is more cost-effective?

ESL offers a significant discount, making it potentially more cost-effective for specific applications.
