Re: [Wrapper-user] Alternative to time as restart delay criteria?

[Leif M. <lei...@ta...>]

Dave,
Currently, the Wrapper itself does not publish itself as a JMX bean.
You are talking about delaying the launch of a JVM so any JMX access
there would not be available as the JVM would be down.

In addition to the fixed delay, we added a new "Paused" state to the
JVM starting in version 3.5.0.  You will need to first enable pausing:
http://wrapper.tanukisoftware.com/doc/english/prop-pausable.html

You can use the Wrapper's command file to send PAUSE or RESUME
commands to the Wrapper as it is running:
http://wrapper.tanukisoftware.com/doc/english/prop-commandfile.html

You can use the on exit properties to tell the Wrapper to pause when a JVM exits
http://wrapper.tanukisoftware.com/doc/english/prop-on-exit-n.html

There is not currently a way to tell the Wrapper to start paused.

Please let me know how this works for you.

Cheers,
Leif
