Re: [Wrapper-user] Multiple instances of wrapper (configured and startet at runtime)

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

Christian,
It is possible to run multiple instances of the Java Service Wrapper
as services on the same machine, but each wrapper's configuration must
have a unique service name and description.   In addition, if the two
services are running from the same directory, you will need to make
sure that they each write to their own wrapper.log file.

There are a couple ways of doing this that might work for you.

1)
I have done things like this before by creating a shared
wrapper-common.conf file which contains all of the common
configurations.  Then create a separate wrapper-app-N.conf file for
each of your services, including the common configuration file:

wrapper-app-N.conf:
---
#include ../conf/wrapper-common.conf
wrapper.logfile=../logs/wrapper-app-N.log
wrapper.ntservice.name=app-N
wrapper.ntservice.displayname=Application N
---

2)
Another solution is to take advantage of the ability to set
environment variables by setting properties, and the fact that any
property can be set on the command line.

Modify the following properties as follows:
wrapper.logfile=../logs/wrapper-%APPN%.log
wrapper.ntservice.name=app-%APPN%
wrapper.ntservice.displayname=Application %APPN%

Then when you launch the Wrapper, do so as follows:
wrapper.exe -c ..¥conf¥wrapper.conf set.APPN=1

The service can be installed as follows:
wrapper.exe -i ..¥conf¥wrapper.conf set.APPN=1

The above will be stored when the service is registered with the
ServiceManager so it will work correctly when starting and stopping
the service.
You will need to specify the APPN value whenever you run the wrapper
with any of its commands.

Let me know how this works for you.

Cheers,
Leif
