[midPoint] Overriding systemConfiguration attributes in config.xml file or using java system properties

[Pavol Mederly]

Hello Fréderic,

there are two distinct concepts:

 1. System Configuration object in midPoint repository,
 2. configuration in config.xml file.

The first one is the "main" one. Here e.g. deployment information (that 
you'd like to change) resides.

The second one is used for low-level information (e.g. where to find the 
repository) or for node-specific information (e.g. node id).

Java system properties can be used to override information in 
config.xml, not in System Configuration object. That's why 
*-Dmidpoint.system.deploymentInformation.name=DEV* does not work.

As far as I know, it is currently not possible to set the deployment 
name from the command line.

The following approach works in similar situations (unfortunately, not 
in this particular one):

https://wiki.evolveum.com/display/midPoint/Configuration+and+Use+of+Constants

You can define a constant in your config.xml file. (So its value is 
settable using -D ... switch.) And you can use this constant in your 
mappings or resource configurations. In the system config it would be 
like this (if it worked):

<deploymentInformation>
         <name>
             <expression>
                 <const>systemName</const>
             </expression>
         </name>
</deploymentInformation>

It's doable, but not there yet. You can always consider 
https://wiki.evolveum.com/display/midPoint/Subscriptions+and+Sponsoring :)

...as for your question on config.xml schema. Unfortunately, nothing 
like that exist yet. We read the file programatically, looking for 
specific keys. Something is here:

  * https://github.com/Evolveum/midpoint/blob/master/infra/common/src/main/java/com/evolveum/midpoint/common/configuration/api/MidpointConfiguration.java
  * https://github.com/Evolveum/midpoint/blob/master/repo/task-quartz-impl/src/main/java/com/evolveum/midpoint/task/quartzimpl/TaskManagerConfiguration.java#L52
  * https://github.com/Evolveum/midpoint/blob/master/repo/repo-sql-impl/src/main/java/com/evolveum/midpoint/repo/sql/SqlRepositoryConfiguration.java#L249

but it's not a complete reference.
