Description:
Even though MaxDeploymentRevision can be found in multiple locations, such as domain properties files (AdministrationDomain.properties, AuthorizationDomain.properties, SYS_domainname.dat, database, etc.), but the change of MaxDeploymentRevision in file AdministrationDomain.properties affects new application's default Max Deployment Revision immediately. No need to restart the TIBCO Administrator server. 
Symptoms:
If the value of MaxDeploymentRevision in file AdministrationDomain.properties changes, new deployment immediately gets the new value as default Max Deployment Revision number. 
Cause:
MaxDeploymentRevision in file AdministrationDomain.properties affects domain's default settings.
