Hello

No need to switch to SAP JVM for this installation.

The error message is Current version: JAVA_HOME not available

The installer is unable to check the current version of java installed on the system.

Please set the environment variable for the user under which you are starting the installation and start the installation again.

NB: Take this into consideration : Do NOT use version 1.4.2_10

Hi,

Where you plan to install DI? is it the same host as CI?

Please ensure correct JDK (based on your OS) is used for fresh installation of DI.

Check note:

Note 723909 - Java VM settings for J2EE 6.40/7.0

Note 716927 - Overview of AIX JVM for NetWeaver 2004 and 7.0 (2004s)

Dear Nicholas,

Above mentioned note ain't helpful..... Host is different for CI & DI.

We have Suse Linux enterprise server11 @ patch level2

Error is below.....

Please help.....

Thanks

Hi Sumit,

   SAP is recommending to use SAPJVM  else you MIGHT need to move to SAPJVM later. Please refer the Note 1495160 - SAP JVM as replacement for Partner JDKs 1.4.2

So to be on safter side, why dont you use SAPJVM  now itself?

To install SAPJVM Please follow the below steps.

1. Download SAPJVM4 from service.sap.com/swdc

2.Uncar and put it in /sapmnt/SID/exe/sapjvm4

3. Set the JAVA_HOME environmental variable path to /sapmnt/SID/exe/sapjvm4

If you are using a java stack, please use the Note 1603093 - SAP JVM 4.1 parameters NetWeaver 2004 and 7.0

Please check and provide your feedback.

Thanks and Regards,

  Hello Vimal,

Ours is ABAP instance.... as we are installing DI. & u saying install it in NFS mount point...

1)Will it impact our CI environment...

2) We have already CI,DB(Cluster services), one dialog instance. But have never used SAPJVM.

     Is it safe to use SAPJVM....

3) any adverse effect , if we dont use SAPJVM,,,,

Please suggest....

Thanks

Hi Sumit,

     Yes. You can use SAPJVM in your DI.

Here you have two choices.

1. Either you can use SAPJVM for your DI , CI , ASCS .

2. If not, you can copy the java folder from your CI to DI and try to make the JAVA_HOME pointing to copied java location.

Check what is the java version in your CI and try to use the same version in your DI also...

CI java version as well as DI java one should be equal..Else you MIGHT face issues later.

Thanks and Regards,

Vimal
