How do you control the initialization order of services

Scott Bostater

I have a server that is made up of multiple services.  Some services are mandatory, other services are optional based on what has been licensed to the end user.  Is there a way to assure that the mandatory services are initialized (via axis2_svc_skel_<name>_create())  before the optional ones?

Hi Bob,

The files will be sorted in alphabetical order when reading the services from the service deployment directory and the services are initialized in that order as well.

RE: How do you control the initialization order of services

The order is not alphabetical (at least not in axis2/c 1.6.0).  Here is what I am seeing in the apache error.log file.  My goal is to have the Common services initialized first.  Currently, it is the 6th service being initialized.  For right now, I am ok since the other 3 services that are dependent on Common (MarketPlace, RPSAdmin, and MRO) are being initialized after Common.  However, it looks like its working by chance, not design.

If the order were alphabetical, then I would expect the order to be:

 

1.       Common

2.       ExternalInterface

3.       ExternalUpdate

4.       FreeWheel

5.       MarketPlace

6.       Network

7.       Placement

8.       Requirement

9.       Rollover

10.   RotationMapping

 

 

For another configuration I see:
