I am running my application on a 64-bit Solaris 10 machine. Currently, my application uses JRE 1.6 32-bit version. I am trying to make it work with JRE 1.6 64-bit version. I successfully installed 64-bit java using the instructions here: How do I install Java for my Solaris x64 computer ? - 1.5.0 and am able to invoke 64-bit java using either
Code:
$JAVA_HOME/bin/java -d64
or by using
Code:
$JAVA_HOME/bin/sparcv9/java
My application always invokes the java executable under $JAVA_HOME/bin. By default, this is invoking the java 32-bit version which I do not want. Of course, I could add the -d64 option to all calls to java in my application. However, I do not want to do that as java is being called from a number of scripts and some scripts are also being shared between multiple platforms.
How do I make the 64-bit java the default? I tried copying over the java executable from under $JAVA_HOME/bin/sparcv9 to $JAVA_HOME/bin. This seems to invokes the java 64-bit version correctly from within my application. However I do not know if this is the right thing to do or if it has adverse side effects.
Thank you for your response! I considered your suggestion - but as I said, since some scripts are common across platforms, if possible, I would like to avoid Solaris specific changes to them.
Also the java executable for 64 bit is present directly under the sparcv9 directory. Usually the executables are supposed to be under $JAVA_HOME/bin, right?
Hi ,
Whenever I am starting JVM it is getting started with Xms as 256MB, which is 1/64 of the Memory available and by default this should happen.
But I want to change and start the every JVM with 128MB.
Is there any way to do or I have to manually specify Xms tag while starting JVM.
Thanks (1 Reply)

I had previous implemented the following in my menu.lst to be able to get to 32-bit operations.
