[Wrapper-user] How do I prevent wrapper from re-starting after exit ?

From: Elizabeth C. <ec...@er...> - 2005-12-05 17:41:18

I have tried using

wrapper.on_exit.default=SHUTDOWN

but the wrapper restarts automatically anyway when it receives an exit from 
the program.

Is there a way to prevent the wrapper from restarting the application when 
we stop the application using an exit() in the program?

I have searched through all the configuration parameters and I cannot find 
anything obvious.

Here is some of what my configuration file contains:

wrapper.single_invocation=TRUE
wrapper.on_exit.default=SHUTDOWN
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp

wrapper.java.classpath.1=../lib/wrapper.jar

wrapper.java.classpath.2=../Test.jar
wrapper.java.library.path.1=../lib

wrapper.app.parameter.1=Test

wrapper.ntservice.name=Test
wrapper.ntservice.starttype=AUTO_START
wrapper.ntservice.interactive=false

Elizabeth,
    What version of Java are you using?  Java 1.2 has this problem due 
to its lack of
support for Shutdown hooks, but newer JVMs should all work correctly by 
default
when System.exit is called.

    Could you please rerun your application with the wrapper.debug=true 
property
set and then post the resulting wrapper.log file?
(Trim log entries from previous runs please.)

    Remove the wrapper.on_exit.default and wrapper.single_invocation 
properties.
They are not relevant here.

    In the case of wrapper.on_exit.default, that is already the default 
value.

    The wrapper.single_invocation property is used to make sure that 
more than
one invocation of the same application are never started even if they 
are located
in different directories.  Most applications will fail on startup due to 
port conflicts
etc anyway, but this makes it possible to output a more useful error 
message.

    You are probably looking for the wrapper.max_failed_invocations 
property.
But as I said, that should not be necessary so I would like to see what 
is really
going on.

Cheers,
Leif

Leif:

I have added the wrapper log, below.

The way this program works is that it has a built in timer that exits the 
program after 2 minutes. It started at 21:55 and exited about 2 minutes 
later. I deleted all the ping-ping stuff between the start and stop.

I have commented out
#wrapper.single_invocation=TRUE
#wrapper.on_exit.default=SHUTDOWN

in the configuration, but I made no other changes (other than 
wrapper.debug=true).

You can see that the JVM restarted the application after it shut down.

Any ideas about this?

Re: [Wrapper-user] How do I prevent wrapper from re-starting after exit ?

From: Leif M. <le...@ta...> - 2005-12-08 05:59:11

Elizabeth,
    Yes, as I thought, it appears that the shutdown hook is not being 
run when your
application calls System.exit.  I did a Google search and am not yet 
sure how this
could be happening as you are using java 1.4.2... :-/  From the logs, I 
can see that
the wrapper's shutdown hook is indeed being registered:
INFO   | jvm 1    | 2005/12/07 21:55:11 | Wrapper Manager: Registering 
shutdown hook

    Any idea on your end?  I have never seen this in any JVM other than 
old 1.2
versions.  I'll post back if I find anything.

    As a workaround, calling WrapperManager.stop() rather than System.exit()
will make sure the JVM exits correctly.

    The problem is that if the JVM exits without its shutdown hook being 
run, or if
the user code calls System.halt() then the Wrapper process will assume 
that the
JVM crashed.  This is why it is being restarted.

Cheers,
Leif
