instructions for Installing SAP JVM

[Former Member]

Hello,

I have downloaded the SAP JVM to use it for Java instances 7.3 as recommended by SAP.

Do i have to do more configuration other than Decompressing the SAP_JVM.SAR file .

Is there a specific path where to decompress it? are there some Variable Environments to modify?

Thanks in Advance

Thanks for your answer,

In the link there is nothing mentioned about the path how and where to install the SAP JVM ?

is there some recommendation about that?

Hi,

As in the links provided above, it mentions that SAPJVM ideally comes automatically with the installed SAP Instance.

However if you want to install/update SAPJVM for SAP Instance manually - the below procedure could be used (JSPM):

The JSPM will 'put' the SAPJVM into the required SAP Instance. There aren't any additional path settings required.

Thanks for your answer,

Actually i do not want to use at all the IBM JDK (i will install the SAP on Redhat EL5, X86_64)

Before the installation i will not have the path: /usr/sap/<SID>/<INSTANCE><NR>/j2ee/JSPM/go , shiould i have to craetae it and then decompress the SAP JVM inside? or i put it usually where the IBM JDK is usually installed in /opt

And for starting the /sapinst we need to have the JRE which is including in the SAP JVM.

Thats why i need to have it before having the instance installed.

Hi,

The moment you start the SAPInst executable from the Installation Master - it will install the SAP JVM automatically as a 'prerequisite' for SAPInst and use it for the installation as well as for later use by the system. Hence no need to download external JDK.

Hello,

As i know we need to have the JRE installed to run SAPinst, isnt?

That is not the case with systems 7.1 and onwards.

Hi,

Yes, what you mentioned is before NW CE 7.2. From 7.2 onwards - no external JVM required.

The java getting licensed is definitely the cause for it
