Re: [Wrapper-user] wrapper not shutting down on Solaris

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

Sean,
    Glad you got things working.  I made the suggested change.  It will 
be in the next released
version.  Thanks for the feedback.

Here the new text in the conf file:
---
# File to write process ID to.  If you change this value and you are
#  using an sh script to launch the wrapper then you must also update
#  that script.  bash scripts do not require any modification.
wrapper.pidfile=/var/run/@app.name@.pid
---

I also added a comment on this in the documentation:
---
wrapper.pidfile

File to write process ID to. This file is used by sh scripts to make it 
possible to tell whether or not the wrapper process is already running. 
If you modify this parameter and you are using a sh script to control 
the wrapper then please make sure that you make sure you also update the 
script to reflect this change.

Example:
wrapper.pidfile=/var/run/myapp.pid

Text in sh.script which needs to updated:
# Process ID
PIDDIR="/var/run"
PIDFILE="$PIDDIR/$APP_NAME.pid"
---


Cheers,
Leif
