`--start-local-management-server` is one option as Alan suggests.
Another option is to make `--start-management-agent` to accept
an optional argument.  VM can accept `--start-management-agent`
or `--start-management-agent=port=1234,ssl=on`.  It may require
more launcher change to support it.
Yes. It requires lot more changes to launcher. Hence optional 
argument to --start-management-agent was not added in order to keep 
the launcher impact minimum.


This is just one option for you to consider.   So the current 
proposal of the new option to start a remote management server, right?
Not necessarily. --start-management-agent=local=true starts local 
server and --start-management-agent=port=1234 starts remote 
management server.

Agent.java
  If --start-management-agent is set, -Dcom.sun.management.* takes
  precedence.  Do you really want to do that?  The new VM option
  intends to simplify the command-line to type in.  I think it's
  cleaner and reasonable if --start-management-agent is specified,
  -Dcom.sun.management.* are ignored (maybe worth emit a warning 
if set)
We can probably document that -D options will be overridden instead 
of emitting a warning.


What is the behavior when -Dcom.sun.management.jmxremote.port=1234 
--start-management-agent port=2345 
-Dcom.sun.management.jmxremote.port=3456?


What is the value of the system property 
com.sun.management.jmxremote.port at runtime?  What port number does 
the management server start with?
As said earlier, values set via new flags override values set by -D 
flags. So 2345 will be the value of 
com.sun.management.jmxremote.port. Added a test case to validate that.



  The implementation uses VMManagement::getVmArguments and scan
  the VM options for -start-management-agent.  The VM is the one
  invoking jdk.internal.agent.Agent::startAgent.  A simpler option
  is to change Agent::startAgent to take an argument parameter
  that will be passed with the argument of --start-management-agent
  or null if not set.

  Similarly for startRemoteManagementAgent and startLocalAgent_name.
Implementing this change requires lot of changes to argument 
parsing in native code and hence it is simpler to handle this at 
java layer.


Can you describe how --start-management-agent option will be used 
for jcmd and any other tool that attaches to a running VM to start 
the agent?  Example command-line will be useful.
--start-management-agent cannot be used by jcmd (or dynamic attach) 
as it accepts flags only in -D format or -D flags with 
com.sun.management removed. That code to parse string passed via jcmd 
was a mistake and hence I have removed it.

Re: RFR: JDK-8187498: Add a -Xmanagement flag as syntactic sugar for -Dcom.sun.management.jmxremote.* properties

2018-02-07 Thread Kumar Srinivasan


Hi Harsha,

Changes look reasonable to me, couple of things that must be addressed:

1. Since this is a main-stream launcher change with a documented and 
supported
option, a CSR is required,  you have  to add and document the option in 
the help page

http://hg.openjdk.java.net/jdk/jdk/file/8cc67294ec56/src/java.base/share/classes/sun/launcher/resources/launcher.properties

2. You also have to create a doc bug so that the doc team will document 
it in the Tools
Reference Guide, and link it to this bug. Does it need a Release note ? 
probably does,
in which case you will have to create Release Note subtask and follow 
the RN process.


3. Is XmanagementAgentTest.java part of tier1 test suite ? If not, then  
I think it ought
to be in tier1 grouping, perhaps best to park this under 
jdk/tools/launcher/management ?



Kumar



Hi All,

After internal discussions, below format for management flags was 
agreed upon.


1. --start-management-agent port=1234,ssl=on(space seperator)
or
2. --start-management-agent=port=1234,ssl=on('=' seperator)

If option 1 is specified, it will be converted to option 2 by the java 
launcher before it is passed onto VM.


With above GNU long format for management options, specifying 
arguments is mandatory unlike before.


--start-management-agent will not be recognized in the current format 
and hence will not default to --start-management-agent=local=true.


Below is the webrev with above changes and corresponding tests.

If I keep it as launcher option, it may need to know JMX agent

I would prefer making it a VM option. I will make the required

I think Mandy's suggestion is to just transform --management 
 so a form that the VM can read. The launcher will need to

Hi,

Besides my private comments to you, there are 2-3 internal tests
which fail.

Have you run all the langtools tests ? There are 4 Windows tests
that fail with langtools:

jdk/javadoc/doclet/testHelpOption/TestHelpOption.java
jdk/javadoc/tool/CheckResourceKeys.java
jdk/javadoc/tool/ToolProviderTest.java

I decided to check in java.c if the -Xss size is too small, and 
set it
to a larger size if it is. I hard coded this size to 32k (I'll 
explain
why 32k later). I suspect this is the part that will result in

In SunCommandLineLauncher.java:

  198 if (home.length()  0) {
  199 String os_arch = System.getProperty(os.arch);
  200 if (SunOS.equals(System.getProperty(os.name))) {
  201 exePath = home + File.separator + bin + 
File.separator + exe;
  202 }
  203 } else {
  204 exePath = exe;
  205 }

I think this should be:

  198 if (home.length()  0) {
  201 exePath = home + File.separator + bin + File.separator 
+ exe;
  203 } else {
  204 exePath = exe;
  205 }

Hi Kumar,

A few minor comments ...

src/share/classes/com/sun/tools/jdi/SunCommandLineLauncher.java

Seems to me this is all dead now:

199 /*
200  * A wrinkle in the environment:
201  * 64-bit executables are stored under
$JAVA_HOME/bin/os_arch
202  * 32-bit executables are stored under
$JAVA_HOME/bin
203  */
204 String os_arch = System.getProperty(os.arch);

os_arch is no longer used and the comment no longer applicable.

This seems to force DUAL_MODE off regardless of what the user may set
it to:

  #ifdef __solaris__
! #  ifdef DUAL_MODE
! #undef DUAL_MODE
! #  endif

why doesn't it just not define DUAL_MODE?

It isn't clear to me why you need to retain the d64 variable at all.

I haven't studied the changes yet but I see you've updated 
test/java/nio/channels/spi/SelectorProvider/inheritedChannel/run_tests.sh. 
I don't think you need the changes at L42-48, instead you can just hg 
rm the 32-bit libraries that are in 
test/java/nio/channels/spi/SelectorProvider/inheritedChannel/lib.


Will do, I was wondering about those libraries.



You might want to bring the changes to serviceability-dev because of 
the change to the JDI launching connector and the JDI tests.


cc'ed.

Re: Fwd: large jar file failed

2011-10-10 Thread Kumar Srinivasan

 IMHO this looks like a valid use case that should be solved in some upcoming 
 release, on all relevant target platforms (Windows/non-Windows, 32/64-bit).

 Is there a bug created yet?

We need a bug/CR on this, I will look into fixing this for the next
available
update release.

Kumar

 We can look to the JVM/JDK for info on how native large file support is 
 implemented, e.g. we might need separate implementations for Windows and 
 Linux/Solaris since O_LARGEFILE is not supported on Windows.

 Thanks for your kind reply of the issue.

 Yes, it seems more like a launcher issue. And if we use 32bit jvm with
 -d64 option (it will auto launch the 64bit jvm)
 it appears an Open() error of EOVERFLOW. And if we use 64bit jvm
 directly , it appears to be an Lseek() error of EINVAL.

 I doubt if there is any workaround such as a jvm option.
 If the issue is with the launcher then I think the only option would be
 to try and use a custom launcher that uses 64-bit file operations.

 Hi Experts

 I need help to solve a JDK issue.

 It is easy to repeat, one created a jar file   2GB , and it failed to
 run.
 By the deeper investigation, I found the error was thrown from the
 SelectVersion() method in JVM .
 What was the error? I suspect it may have been EOVERFLOW as the jar
 file
 was not opened with O_LARGEFILE set.

 David Holmes
 

 Inside the openjdk source code(/share/bin/java.c), I found some
 interesting notes as:

 * A NOTE TO DEVELOPERS: For performance reasons it is important that
 * the program image remain relatively small until after SelectVersion
 * CreateExecutionEnvironment have finished their possibly recursive
 * processing. Watch everything, but resist all temptations to use Java
 * interfaces.

 OK, the fact is , now there is a jar file2GB , and if it could pass
 the SelectVersion() check in JVM?
 Or any advice ?

 Thanks
