Installing SAP NW 7.3 on HPUX - JDK VERSION

[former_member199849]

Hi experts

I have a doubt about JDK version for SAP NW 7.3, I have read some notes that SAP NW 7.3 install by itself SAP JVM 6, so It is no necessary to install JDK 1,4.2 and also SAP NW doesn't work with JDK 1.4.2, but when I execute sapinst it doesn't run, it asks me to check if JDK is installed and if a I set the variable SAPINST_JRE_HOME.

I am a little confused. before starting SAPINST, do I need to install JDK? and which version? in installation guide it doesn't say anything about JDK.

Do you have any idea.

Thanks

Hi,

My problem was resolved, I used Xmanager and I don't need to install JDK 1.4.2, besides HPUX by default install java1.5 and java6.

Thatz good.As I guessed NW 7.3 SAPinst support SUN JDK 1.6 as well.Hope this makes clear your concepts about OS JDK and SAPJVM !

In PAM says the SAP NW 7.3 is compatbile with SAPJVM 6.1, any idea about the error?

I am using Xterm to connec graphically Xming

Hi,

Instead of using Xming, i could advise you to use Xmanager or reflection-X.

Hi Andy,

I would again re-iterate SAPJVM is used for Netweaver engine to work and not for the installation itself which is done using SAPinst. SAPJVM is a by product of installation and is extracted from kernel DVD during installation. Please install JDK for HP site on you system, set JAVA_HOME and then start the installation.

PS: SAPJVM is not a full fledged JVM. It only has server side features and not client side.

HI Ruchit

So which version of JDK do I have to install for SAP NW 7.3?

Thanks

[Former Member]

Hi Andy,

I would suggest trying with JDK 1.4 first latest or n-1 th patch.

You can check OSS note 716926. While it is for release upto NW 7.0 you can use it for installing OS JDK.

Hi,

Just my 2 cents worth. SAPJVM should extracted when you launch the sapinst. Just ensure you are using the latest installation master and kernel DVD.

As a workaround, you can manually download SAPJVM from

Support Packages and Patches --> A-Z Index -->N > SAP NETWEAVER > SAP NETWEAVER 7.3--> Entry by Component --> Application Server Java --> SAP JVM 6.1 and extract it to the \usr\sap\<SID>\SYS\exe\JVM

Hope it helps,

Cheers,

Hi Andy,

SAPJVM is used by the Netweaver system.It wouldn't extracted till SApinst does it. SAPinst itself needs JAVA to run which is not SAPJVM but proper JDK which needs to be pre-installed.  As far as I remember based on an NW 7.3 test installation I did several months back JDK 1.6 also worked though SAP reommends 1.4 releases normally.Typically when you get to that screen SAPinst should give you the hint about supported JDK versions.
