Harmonizing JDK versions before homogeneous system copy

[Former Member]

My enviroment ECC6/Oracle 10.2.0.2/ Solaris 10 SPARC

I intend to do a homogeneous system copy using database specific methods.

The JDK in my target system (JDK 1.5.0_x )is a higher than of the source production system(JDK 1.4.0_x ). The system copy guide says the JDK version must be the same in both target & source systems. Where can I download this JDK 1.5.0_x so that I upgrade my production system ? Is the upgrade likely to affect the SAP installation in the source system/server ?

Oracle release in both systems is 10.2.0.2 but I need to check if the patch level is the same in both databases ? How do I go about this ?

Hi,

Java 1.5 version is not supported by SAP. you have to use java 1.4_xx version only.

Check SAP note 723909.

Install the 1.4.2 JDK on the filesystem and point the JAVA_HOME to that. No need to uninstall anything (and I wouldn't do so since certain Solaris OS functions rely on it).
