So does this mean that the 64 bit version will only get run if the -d64
flag is used?
This is what I get
$ truss -t exec java -version
execve("/usr/jdk/instances/jdk1.5.0/bin/java", 0xFFBFFDE4, 0xFFBFFDF0)
argc = 2
execve("/usr/jdk/instances/jdk1.5.0/bin/java", 0x00031E18, 0x00032ADC)
argc = 2
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
truss -t exec java -d64 -version
execve("/usr/jdk/instances/jdk1.5.0/bin/java", 0xFFBFFDDC, 0xFFBFFDEC)
argc = 3
execve("/usr/jdk/instances/jdk1.5.0/bin/sparcv9/java", 0x00031E18,
0x00032ADC)
argc = 2
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_06-b05, mixed mode)

hello John,
first check that you have installed the solaris sparc 64-bit packages
(if you use the sparc platform) in addition to the sparc 32-bit packages
(you may check that you have the 64-bit binaries in the
$JAVA_HOME/bin/sparcv9 directory, and in $JAVA_HOME/jre/bin/sparcv9,
plus libraries in $JAVA_HOME/jre/lib/sparcv9).
the binary $JAVA_HOME/bin/java is a 32-bit wrapper that will launch the
64-bin binary.
#truss -t exec $JAVA_HOME/bin/java -d64 -version
execve("/usr/jdk/instances/jdk1.6.0/bin/java", 0xFFBFFDEC, 0xFFBFFDFC)
argc = 3 execve("/usr/jdk/instances/jdk1.6.0/bin/sparcv9/java",
0x0002B170,
0x0002BE30) argc = 2
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105) Java HotSpot(TM)
64-Bit Server VM (build 1.6.0-b105, mixed mode)
so you can see that the 64-bit binary is launched:
/usr/jdk/instances/jdk1.6.0/bin/sparcv9/java
