Dispensable Functions with Impacts on Security 

In productive mode, you should only have those services active on the J2EE Engine that are needed. For assistance on determining which services you need, see SAP Note 871394. This note provides a list of mandatory and optional services on the J2EE Engine in the AS-Java, based on the service references and independent of a specific use case.

The actual services needed depend on the applications that you are using on the J2EE Engine. Therefore, the list of services provided with the note is only a recommendation. To use this list on a productive system, you have to adjust the service classification according to the AS-Java system functions that you require for your specific use case.

The note contains several attachments, including an excel file about the AS-Java usage type of the SAP NetWeaver with several spreadsheets. For information about the contents of the worksheets, see the tables below.
