Config setting added in DSS are not reflecting in configs



User has added setting in DSS and restarted the server. But the changes are not reflecting in System Management Application (SMA).

Error Messages

Not Applicable

Steps to Reproduce

1. Create DSS as below:

OwningRuleset                              Setting Purpose                                                      Value
Pega-Engine database/databases/PegaDATA/dataSourceReadOnly                          java:comp/env/jdbc/PegaRULESReadOnly
Pega-Engine database/databases/pegarules/datasourcereadonly                              java:comp/env/jdbc/PegaRULESReadOnly
Pega-Engine prconfig/collections/mru/propertyreference/instancecountlimit               130000
Pega-Engine prconfig/alerts/database/blobsizeread/threshold                                     10
Pega-Engine prconfig/alerts/database/blobsizewritten/threshold                                  10

2. Restart the application server.
3. Go to SMA and verify the DSS.  The values are not reflected under Configuration Management.

Root Cause

An issue in the custom application code or rules:

DSS setting purpose is not configured properly and setting related to PegaRULES Db connection configuration is not allowed in DSS 
because "Data-Admin-System-Settings.ValidateKeysContent" Step 7 do not allow PegaRules connection in DB as DSS.


Perform the following local-change: 

1. Add the below DSS in prconfig.xml file.

Pega-Engine   database/databases/pegarules/datasourcereadonly                         java:comp/env/jdbc/PegaRULESReadOnly

2. Restart the server after doing the above modifications. See the changes: 5 DSS in Administration > Configuration Management in SMA( 4 DSS with have source as DSS and 1 will have prconfig).
