You can use a combination of global properties and system properties for certain customizations. For example, if you wish to distribute a system that has a core set of properties overridden but need to customize the last few for each installation.
- Activate the properties in the <classpathRoot>/alfresco-global.properties file.
 - Set all common defaults for your system.
 - 
        On each installation, add the final configuration values. For example:
        
-Ddb.username=SkyVault -Ddb.password=SkyVault -Dindex.tracking.cronExpression='0/5 * * * * ?' -Dindex.recovery.mode=AUTO -Dalfresco.cluster.name=ALFRESCO_DEV
