Standard Edition vs. Enterprise Edition
Oracle distributes their software in two alternative releases, Standard Edition (SE) and Enterprise Edition (EE). From Oracle9i release1 both these releases are on the same CD-ROM so when you install Oracle you have to choose either to install Standard Edition or Enterprise Edition. IFS Applications are built to work with Standard Edition but some extra features are available when IFS Applications is used with Enterprise Edition. Remember to install the edition you have chosen to license from Oracle.
Besides the license fee for the different releases the only difference between Standard Edition and Enterprise Edition, from an IFS Applications perspective, is which Oracle software has been installed and that Enterprise Edition offers some more sophisticated features. Oracle Standard Edition includes all the software needed to run the database e.g. RDBMS, SQL*Plus, SQL*Net, administration software etc. There is no performance difference between Standard Edition and Enterprise Edition (unless using some additional EE features), just the amount of products being installed. So installing EE instead of SE will not always gain performance in your instance, in fact performance can decrease since the EE installation is much larger and starts a number unused background processes.
IFS recommends that you install Oracle Standard Edition unless you need to use Enterprise Edition functionality such as Oracle Real Application Cluster, Oracle StandBy Database, Partitioning, OLAP etc.
Due to an unpublished bug 2211325 it is impossible to make a custom Standard Edition installation using the Oracle9i release2 CD.
The only way to make a proper Standard Edition installation of Oracle9i release2 is to make a complete Standard Edition installation and then uninstall all unnecessary products.
All other attempts to make a custom Standard Edition installation will end up in an Enterprise Edition installation and this will cause licensing problems. Therefore it is extremely important to make the installation right from the beginning.
