Oracle Database : Standard Edition vs Standard Edition one (SE vs SE1)

We had an environment where Standard Edition one was required and engineers installed by mistake Standard Edition.

This caused us to stress due to licensing issue from Oracle. 


However, to be free you should know that Standard Edition and Standard Edition One are the same install (as given by Oracle), it's just 2 different options given to you during installation, though the installation is same. 

These 2 just differ in only feature (and licensing), you can have SE running on  RAC however, SE1 is not supported for RAC.
If you do, then you pay :)

As per the Oracle document -

How to Install "Standard Edition One" (Doc ID 352618.1)

which confirms for  Oracle Database - Standard Edition - Version 10.1.0.5 and later - 

“Standard Edition One is a licensing edition. It is same as Standard Edition for a machine that has 1 or 2 processor sockets. No packaging differences. It was called Standard Edition One as it was originally Standard Edition for a 1 processor socket machine but with the release of 10g, we expanded it to a 1 or 2 processor socket machine.

So basically, if you install the Standard Edition, you will have the correct software.


The only difference between "Standard Edition One" and "Standard Edition" is that Standard Edition One must NOT be used on RAC, since there will be a licensing issue. It means that to install Standard Edition One, you have to install Standard Edition software and it can NOT / must NOT be used in a clustered environment (RAC).”
