I think it should be ''-Xrundvmti:all'' rather than
''-Xrundjvmti:all'' -- the
very first version of the DVM provider might have used that name, but not
subsequent ones.

[dtrace-discuss] Where is dvmti Agent? (not djvmti as documented...)

All,

Could the current name of the Java DTrace Agent be updated in the
online documentation?  This is REALLY hard to find at present.

Thanks to Alan & Jarod, the fix is found:

export LD_LIBRARY_PATH_64=/opt/dvm/build/sparcv9/lib
export LD_LIBRARY_PATH_32=/opt/dvm/build/sparc/lib
export JAVA_TOOL_OPTIONS=-Xrundvmti:all

Then it works:

/usr/jdk/jdk1.5.0_07/bin/java -version 
    OR
truss -fa -t open -v open /usr/jdk/jdk1.5.0_07/bin/java -version

Thanks,
Joel.

[dtrace-discuss] Where is djvmti Agent?

Russ,

Yes I have.  That is were I downloaded the dvm.zip file from.   However,
several other references refer to the provider as "djvm[tp]i". 

The references I used were:

https://solaris10-dtrace-vm-agents.dev.java.net/
http://blogs.sun.com/ahl/entry/dtrace_presentation_at_javaone
http://blogs.sun.com/ahl/entry/javaone_dtrace_session_2006
http://blogs.sun.com/ahl/entry/dtracing_java
http://blogs.sun.com/ahl/entry/open_sourcing_the_javaone_keynote
http://blogs.sun.com/bmc/date/20050418#your_java_fell_into_my

It would be helpful to change all the references listed above to
reference "dvm[tp]i" instead of "djvm[tp]i" would be
helpful.

And/or updating "https://solaris10-dtrace-vm-agents.dev.java.net/"
with updated examples from the above references.  That way, only
the "https://solaris10-dtrace-vm-agents.dev.java.net/" site needs to
be referenced.

Thanks for listening,
Joel.
