SUN Solaris Converting JVM to 64-Bit

[Former Member]

Is anyone familiar with the stpes needed to convert a J2EE instance using 32-bit Java to 64-bit on Sun Solaris?

The directory structure on Sun is a bit stange with "sparcv9" directories below /usr/java/bin and usr/java/jre/bin and /usr/java/jre/lib. The "sparcv9" directories contain the 64-bit java code.

Thanks,

Hello Dan,

Unfortunately it is not easy to switch from 32bit to 64bit. The procedure that you need to use is called heterogeneous system copy. Please refer to the following documentation:

Thanks for the reply Ventsi. I guess I didn'

t make myself clear. The SAP J2EE engine is 64-Bit. It's the Java executable and the JRE installed on the server that is 32-Bit.

Therefore, I do not need to convert the SAP J2EE instance but rather convert it to use the available 64-Bit Java executables.

I'm pretty sure you're NOT using the 32bit binary to run a SAP-J2EE instance...

The "normal" version is 32bit - yes -but SAP will use the 64bit version.
