Re: [Wrapper-user] Updating running service

[Mirron R. <mi...@no...>]

Hi.
Just to share our solution to this problem.
We need to upgrade wrapper on various OSes and do it via shell script that
stops service copies files and starts the service.
Indeed, restarting the service usually requires additional permissions, and
there are cases when upgrade does not complete and needs manual
intervention (i.e. to start the upgraded service).

It worth a notion that we evaluated the possibility of having additional
"upgrader" service, which will do all the work. The thing is that if the
original service has the needed credentials, then the procedure described
above will work anyway. But if the customer does not want to provide needed
credentials, then upgrader service will not work also.

It seems that if wrapper had a possibility to replace its files, it would
work best way. The wrapper process should be able to replace files it has
opened and then restart.
