it is suceesfully installed but java path not set with below command

3.Set Java Path(Note: Set Java path which location you saved dump(software) installation Master DVD)

JAVA_HOME=/usr/java/IBMJava2-AMD64-142-SDK-1.4.2-12.0.x86_64;export JAVA_HOME

SAPINST_JRE_HOME=/usr/java/IBMJava2-AMD64-142-SDK-1.4.2-12.0.x86_64/jre;export SAPINST_JRE_HOME

CPIC_MAX_CONV=500;export CPIC_MAX_CONV

HI Mohsin M,

After RPM installation usually it installed in /opt/IBMJava2-*

So first try to location the installed rpm path.

and add the following lines in your .bash_profile of root user.

logout and login again with root user.

JAVA_HOME=/opt/IBMJava2-amd64-142 export JAVA_HOME

SAPINST_JRE_HOME=/opt/IBMJava2-amd64-142 export SAPINST_JRE_HOME

CPIC_MAX_CONV=500 export CPIC_MAX_CONV

Check the PATH has define properly by running the following command.

env | grep JAVA_HOME

Output will be like this.

JAVA_HOME=/opt/IBMJava2-amd64-142

Gentlemen,

please be aware of the fact that the only supported IBM JDK for SLES is delivered by Novell. The package available from the IBM page is not supported by Novell !

You find more information on this topic in SAP note

[1172419 - Linux: Supported Java versions on the x86_64 platform|https://service.sap.com/sap/support/notes/1172419]

Thanks,

Hannes

Dear Mohsin M,

the IBM JDK you are using is not supported by Novell! However, if you have a JDK support contract with IBM, you might be able to get support for it in case of SAP J2EE issues which can be traced back to the IBM JDK.

Anyway, I strongly recommend to use 'java-1_4_2-ibm-1.4.2_sr13-0.4' which is delivered through YaST Online Update Channel.

In case you really want to proceed, I see the following:

2)rpm -ivh IBMJava2-AMD64-142-SDK-1.4.2-13.0.x86_64.rpm

and then

JAVA_HOME=/usr/java/IBMJava2-AMD64-142-SDK-1.4.2-12.0.x86_64;export JAVA_HOME

Does the ...SDK-1.4.2-12... directory exist after installing version ...SDK-1.4.2-13... ???

Thanks,

Hannes

[mohsin_m3]

Sorry haans,

its Typo mistake it is

SDK-1.4.2-13... and not SDK-1.4.2-12...

I have installed rpm -ivh IBMJava2-AMD64-142-SDK-1.4.2-13.0.x86_64.rpm

if this is wrong ,

Pls let me know form where i can download 'java-1_4_2-ibm-1.4.2_sr13-0.4'

Pls send me link

you can download the Novell Java either from download.novell.com or via rug/zypper or yast

[nelis]

As Hannes has already mentioned install the IBM Java SDK via YaST. Do a search for java and then select the java-1_4_2-ibm-devel(SDK) package and java-1_4_2-ibm package(JRE).

Once installed then create a file /etc/profile.local and add your JAVA_HOME variable export to this file. The only other thing to do then is apply OS specific requirements: Note 958253 - SUSE LINUX Enterprise Server 10: Installation notes.
