Order of starting of services
Hi!
I use SM 3.2.1 and I have some services in hotdeploy directory.
Some service accepts JMS messages and sends NM to other service.
The issue is when SM is starting, just after JMS service is started - it
receives immedially JMS messages from external ActiveMQ and sends NM to
other service, but last one could not be yet started.
So, I see the aim is to set some special order of starting services or
to block execution of JMS service until all (needed) services is started.
Is it possible? What solution of actual problem is present?
Thanks in advance!
Truly yours,
Ivan Pryvalov.

Hi to all developers of SM!
If I have few SAs, when SM is starting, initialization order of SAs is
not specified?
Could I do something with my issue (JMS service begins process
JMS-messages and sends NMR to other service, but last one is not yet
started)?
Thanks,
Ivan Pryvalov.

the reason was following: I had old service-stuff (sa) and SA with JMS
consumer just send NMR to some service in that sa

so in your case initialization order is not specified (AFAIK), that is why
you got this problem,
what is the reason of not putting both services in one Service Assembly?

Yes, I have 2 SAs: one SA contains JMS consumer service, other SA
contains service (servicemix-bean) with logic of processing.

Can you provide some more details? What services you have (what components)?
Do you have one service assembly or more?
Order of starting SU is probable the same as they are specified on SA
dependencies but if you have more than one SA then order of their
initialization is not specified
