Question: What is the difference between HA for ABAP and HA for Java?
Answer: Within SAP NetWeaver 6.40 ABAP the Message Server and the Enqueue Server are integrated within the ABAP Central Instance (CI).
In SAP NetWeaver 6.40 Java the Message Server and the Enqueue Server are implemented as services within the SAP System Central Services Instance (SCS) and separated from the Central Instance (CI) this way.
With SAP NetWeaver 04s ABAP the Message Server and the Enqueue Server can be separated from the Central Instance (CI) to the ABAP SAP Central Services Instance (ASCS) in the ABAP stack also (which is recommended for HA setups due to the ASCS is a light component that can be switched over easily).
