You can add a Dynamic System Settings rule to change default system behavior. For
    example, by default, encryption and authentication are not enabled for communication among
    search nodes. To enable encryption, create the
      indexing/distributed/enable-inter_node_encryption Dynamic System Setting and
    set it to true. 
    - 
        In the Dev Studio header, click . 
      
- 
        On the Create form, enter values in the fields to define the Dynamic System Setting.
           Options include:
        
          - 
            In the Owning Ruleset field, enter the owning ruleset, for
              example, Pega-RULES. 
            If no ruleset is associated with the data instance, when the data instance is
              saved, the system assigns a ruleset from the current application, which assists with
              application packaging. 
- 
            In the Setting Purpose field, enter the name of the setting,
              for example, indexing/distributed/enable_inter_node_encryption,
              where the key structure has the following components.
            
              
                -  File type – Specifies the kind of setting for the instance. 
                    - 
                      prconfig– Used for prconfig.xml
                      settings.
- 
                      properties– Used for
                        prbootstrap.properties settings.
-  blank (no value entered) – Used for unspecified
                        Data-Admin-System-Settings. 
 
- Setting name – Specifies the name of the setting and can include long strings
                  that are divided by slashes or periods.
- Node classification – Specifies the node classification for the instance. For
                    prconfig.xml settings, use default. For
                  example, the prconfig.xml settingasyncservices/enableas a Dynamic System Setting isprconfig/asyncservices/enable/default.
