SAP JDK - Best Practice

[Former Member]

Hello Experts,

We are in process of upgrading our JDK from 17 to 22. We are wondering about the best practice. We checked SAP note 718901 and 731269.

After checking this note, we are wondering about best practice. How JDK should be installed?

We are using Windows 2003 with Oracle 10.2.0.2. When you install JDK it goes by default to C:\j2sdk1.4.2_17-x64. If we upgrade to 22, it creates new folder c:\j2sdk1.4.2_22-x64 and we need to reconfigure JAVA path and JAVA_HOME all places i.e. SDM, Config Tool and Visual Admin.

We are wondering if we install JDK to C:\JDK and during upgrade if we provide that path, we shouldn't have to change JAVA_HOME in all places.

Is it possible?

We tried making changes as per note 718901 with option 1 but it doesn't change in all places in config tool for JAVA_HOME. As per note 731269 both the JDK should be available for startup to sync file system and database. We are kind of confused.

Thanks in advance.

Thanks,

Miral.

This is not possible.

First you have to change in instance profile and in environment variable. Then change in startup batch file of visual admin, config tool and SDM.
