Setting global properties for RTC Jazz Build definition

I have several Build Definitions in RTC/Jazz and i use a variable to set out DB-Release in various Build Definitions

• Build-Lib
• Build-Server-App
• Build-Run-Test-Server
• Build-Client-App
• Build-Run-Test-Client

and in all Definitions i use the Property DB_SCHEMA,

DB_SCHEMA = 8.1

once we update our DB and use a new Schema i have to set the Build Property up to

DB_SCHEMA = 8.2

now i must update all Build-Definitions... and if i forget one or i misspell something, then my boss gets mad at me - joking, but honestly, i don't want to make mistakes

--> how can i define a global Property that can be used in all Build-Definitions?

I don't see any global property in the help page, so you might consider developing a program:

• using the RTC Java API

• for each build definition, setting the property to the expected value (as in this thread)

  IBuildDefinition definition = (IBuildDefinition) buildDefinition.getWorkingCopy();
  definition.setProperty("propertyName","");
  definition = buildClient.save(definition, monitor);
