Have you received an Oracle audit request?

If you have been contacted by Oracle License Management Services (LMS) or Global Licensing and Advisory Services (GLAS) and have not recently conducted a review of your estate’s oracle licensing, then it’s essential to take action immediately. 

Do not panic, but do not ignore the audit letter* either. Instead, consult with an independent expert such as Xynomix. Our experts can assist in establishing any potential risk of non-compliance and recommend swift remedial actions.

In the event that your audit is imminent, Xynomix can provide you with enhanced support and guidance. We’ll even negotiate with Oracle LMS/GLAS on your behalf, using our expert knowledge and strong relationship with Oracle to get the best deal possible.

*It is worth noting that an authentic audit letter will only ever come directly from Oracle LMS or GLAS – never from an outside third party.

Key Oracle licensing risk factors

Over time, business needs inevitably change and the impressive flexibility of Oracle database architecture allows you to meet those needs as soon as they arise.

However, organisations can easily find themselves at risk of accidental non-compliance with Oracle licensing rules due to a large range of factors, with fines in excess of hundreds of thousands of pounds and – in many cases – even millions.

Keeping abreast of licensing metrics that may have changed from initial purchase, reducing licence sprawl, ensuring correct support fees, optimising for the cloud, and utilising your licences whilst remaining compliant, is a complex area of risk.

Organisations deploying VMware are at particular risk of heavy non-compliance bills, due to the complexities associated with virtual machines and how Oracle views them.

Xynomix provides clear and concise information on your Oracle licensing, your exposure to risk, and – as an extension of your business team – we function as the essential interface between Oracle and yourselves, should the need to resolve any licensing negotiations arise.

Frequently asked questions


Are Oracle License Audits requested at random?

Not entirely, no.


There are a whole host of triggers for an Oracle License Audit, including the length of time since your previous hardware refresh and any previous cases of non-compliance.

What are the most common areas of non-compliance?

Accidentally enabling Enterprise Edition features whilst using Standard Edition is one of the most common occurrences due to how easy it is to do.


Failing to declare mergers and subsidiaries is another unfortunate scenario. If your organisation changes structurally, it is essential that this is factored into your Oracle licensing.


To help you remain compliant, we’ve outlined the most common Oracle Licensing Pitfalls and, crucially, how to avoid them.


Can Oracle compel me to cooperate?



Oracle owns the intellectual property rights to the software you use. 


Therefore, Oracle has a legal right to audit its customers, ensure that their licensing is in line with agreements made.

How long do I have to respond to an Oracle License Audit letter?

The typical time is 45 days, as per Oracle’s standard agreement:


“Upon 45 days’ written notice, Oracle may audit your use of the software programs”.


There are variations, depending on your territory or specific agreements however, so it’s best to check your agreement with Oracle.

What if I have an ASFU License?

An Application Specific Full Use (ASFU) License is agreed with the application vendor – not Oracle.


This means that Oracle License Management Services (LMS) or Oracle Global License Advisory Service (GLAS) have no audit right to make you comply with an audit for ASFU licenses.  This can only be achieved by going via the partner that sold the licenses, as they are responsible for ensuring compliance with Oracle.

Are there any differences between an Oracle License Review and License Audit?

The Oracle License Review – also known as an estate review – is the service offered by Xynomix in which we compare your licensing agreement against your hardware configuration, CSI numbers, and Org Reports.


An Oracle License Audit is the process of Oracle verifying the integrity of your licensing. Confusingly, LMS and GLAS sometimes refer to this informally as a license review.

Can I respond to the audit on my own?



You have every right to respond to an Oracle License Audit request as you see fit. However, unless you possess a vast amount of Oracle licensing experience internally, it’s prudent to discuss this process with a trusted provider of database consultancy

Does an Oracle License Review guarantee compliance?

Only Oracle License Management Services (LMS) or Global Licensing Advisory Services (GLAS) can officially declare an organisation compliant.


However, a Xynomix Oracle License Review is conducted in line with criteria used by Oracle and is therefore a highly reliable perspective.

Is there a minimum number of Named User Plus (NUP) Licenses required to be purchased?

Yes – you must license 10 NUP License users per server.


Or, if you’re on Oracle Enterprise Edition, you must license at least 25 users for NUP Licensing.


You can find out more Named User Plus Licensing at

What are the main differences between Named User Plus (NUP) vs Processor License

Named User Plus Licensing is the licensing of the user.


CPU Licensing is licensed by the CPU if you’re running on Oracle Standard Edition.


If however, your organisation uses Enterprise Edition, CPU licensing is licensed by the core. It’s worth keeping this in mind because some CPUs now have as many as 12 cores as standard. This means that if you add a new CPU on Enterprise Edition, you will need to license each core which can get quite expensive.

Can I Use Real Application Clustering (RAC) with Oracle Standard Edition (SE2)?

As of Oracle 19c, RAC is no longer available on SE2 (Standard Edition). Ordinarily, you will be required to upgrade to Enterprise Edition.


There are alternatives, however.


These include third party options such as Dbvisit Standby, SEHA (Standard Edition High Availability), and more covered in our 7 Options for Migrating Oracle SE2 & RAC to 19c guide.

How our Oracle License Review works

Only Oracle can pronounce the result of an audit, but Xynomix’s Oracle License Review of your estate mirrors the specific doctrines of Oracle’s audit process. This means we can deliver highly in-depth reporting of your overall database estate. 

The aims of our Oracle License Review are to discover, gather, and review Oracle software licensing information and compare this against your hardware configuration, supported CSI (customer support identifier) numbers, and Oracle Org Reports. 

Our team looks specifically for known procured licences covering the following;

  • Number of users/multiplex users
  • Named User Plus (NUPs) and processor licence metrics
  • Hardware processor and core count
  • Full Use or ASFU licences
  • Highwatermark exceptions
  • Database options installed (i.e. Advanced Data Guard)

Our bespoke Oracle License Review maps this information against supported or purchased licences and collates usage of Oracle Programs, allowing us to highlight any areas of concern or potential risk to your organisation.

The results of these reports serve as informative guidance in the event that Oracle performs a license audit.

There are also many cases where organisations are actually over-licensed. Our database experts can identify opportunities for license optimisation and cost reductions, which can result in some very significant savings.
