Camel stop routes and start

[majid <mo...@peerius.com>]

Hi all,

I have a camel application where I am parsing a large XML file and doing
some operations on the items of the file. I want to be able to stop/and
re-start manually the application.

So when I stop all the routes of my camel context while the application is
processing the file, and restart again, the camel context seems to have
somewhere in the cache the old file instead the new one I have put in the
folder.

Does anyone have an idea on how I can mark everything as completed even if
the I stop the process in the middle ?

Cheers
Majid

Hi everyone,

Indeed there's a trick for forcing the shutdown of a context (or a
particular route). You need to retrieve the currentShutdownTaskFuture of
the DefaultShutdownStategy and call cancel(true) on it.

Also, you can have more than 100 camel contexts in a single JVM, we're
doing it. But of course, your server needs to have enough memory :)

Antoine.

Camel Context holds the reference of components, languages, data formats. You cannot share the direct:endpoint across the camel context.

I don’t think it’s not a good choice to create 100 camel contexts in a single JVM.

Can you try to create a new route instead restart the one route?

I finally stopping the whole camel context.

I am wondering how costly is the operation of creation many camel contexts
(one per customer) ?
I will have around 100 camel context in my JVM, is it expensive ? or should
I use only one ?

Hmm .. you are stopping the route (shutdown) while processing a big XML file. A stopRoute is not like a kill (doesn’t exist - afair). Looking into the DefaultShutdownStrategy documentation might be of help. Do you see any warnings about the route shutdown within the logs?

Hi Harald,

Yes, I can but I am using the same camel context for other tasks, I stop
these routes and restart them when need and keep others.

Hi Majid,

you wrote that you stop all routes, have you tried to stop the CamelContext instead? According to [1] stopping and restarting the whole CamelContext it is performing a ‘cold’ start. That’s what I would try next.

harald
