SAP JVM 5.1 / SAP JVM 6.1 - versus SUN

[Former Member]

With WAS 7.1 / 7.2, per PAM the only supported JVM's are SAP JVM 5.1 / SAP JVM 6.1. Specifically that means, SUN, IBM and HP are no longer supported. Question: Where can I find details on SAP JVM 5.1 / SAP JVM 6.1? I assume those are essentially SUN SDK 1.5/1.6 with SAP's own implementation around; is that correct?

Hello,

SAPJVM is very much platform dependent and is available for all different platforms.

From NW 7.10 onwards, SAP has come up with its own JVM. So no longer part of Sun, IBM, HP.

Thanks & Regards,

Hi,

use this: https://cw.sdn.sap.com/cw/docs/DOC-106773

as your start for exploring the SAP JVM.

To my knowledge, the SAP JVM is 100% Java standard compliant but offers a better (long-term) support compared to other vendors. After all, the SUN Java entered end of maintenance from SUN some years ago and the version for SAP is now the -b, business version of the JDK 1.4.

Should be interessting to know if the SAP JVM is the same for all OS supported (like: AIX, HPUX, Linux, Windows, etc), in terms of performance, bugs (?) and parameters.
