We are running SAP applications on an Oracle database. May we install and run applications of other software vendors on that database as well?
The answer depends on how you are licensing the Oracle database. If you have purchased a license for the database from a third-party vendor (not SAP), you may also run non-SAP software on that database. If you are licensing the database directly from SAP, you may only run SAP software on that database.
In the first case, where you are licensing the database from a third-party vendor, you enter a so-called “interface” contract with SAP which lets you use SAP software on the third-party database. In the second case, where you are licensing the database directly from SAP, SAP grants you a so-called “runtime” license.
