Updating dynamic system settings by using a direct connection to the database

To automate updating dynamic system settings by connecting directly to the database, complete the following steps. This method is most commonly done for a stopped instance.

1. Create one or more .json files that specify the names and new values of the dynamic system settings.
   • The specified dynamic system setting names must be valid.
   • One or more dynamic system settings can be specified in each file.
   • You must specify the setting value, setting name, and owning ruleset for each dynamic system setting to be updated, in the format:

                 {"dass":[
                 {"pySetting":"DASSValue1","pyPurpose":"DASSName1","pyOwner":"DASS1Owner"}, 
                 {"pySetting":"DASSValue2","pyPurpose":"DASSName2","pyOwner":"DASS2Owner"}]}

   For example: 

               {"dass":[
                   {"pySetting":"200",
                     "pyPurpose":"mobile/search/results/maxRecords",
                     "pyOwner":"Pega-UIEngine"}, 
                   {"pySetting":"true",
                     "pyPurpose":"indexing/notify",
                     "pyOwner":"Pega-RULES"}
               ]}

2. In the prpcUtils.properties file, specify the file names that you created in step 1.

   Property name	Value
   dass.filePath	One or more path names that specify the files that specify the dynamic system settings to update, delimited by commas and ending with a semicolon. If the path is a directory, then all .json files in that directory will be processed. For example: C://file1.json,C://dir1//file2.json,C://dir2;

3. Configure the common properties in the prpcUtils.properties file.

   Property name	Value
   pega.jdbc.driver.jar	Path to the database driver .jar file.
   pega.jdbc.driver.class	The database driver class.
   pega.database.type	Database vendor type.
   pega.jdbc.url	URL of your database.
   pega.jdbc.username	Database user name.
   pega.jdbc.password	Database password.
   rules.schema.name	If you use a split schema, the value for the rules schema name. If you do not use a split schema, the value for the schema name.
   data.schema.name	If you use a split schema, the value for the data schema name.

4. Save and close the prpcUtils.properties file.
5. To populate the dynamic system settings, run the prpcUtils.bat or prpcUtils.sh script with the updateDASS option, for example: prpcUtils.bat updateDASS
   1. Optional: Pass one or more arguments.

   prpcUtils script argument	Value
   connPropFile	The full path to the connection.properties file that includes information for multiple targets.
   driverClass	Your JDBC driver class. For example, oracle.jdbc.OracleDriver.
   driverJAR	Location of your JDBC .jar file.
   dbType	Database vendor type, such as mssql, udb, oracledate, postgres, and db2zos.
   dbURL	JDBC URL to the database.
   dbUser	Database user name.
   dbPassword	Database password.
   archivePath	Full path to the archive to be imported or exported.
   propFile	The full path to the properties file, to override the default prpcUtils.properties.
   hfixAction	If manageHotfixes is selected, sets the hotfix operation. Valid values are commit, rollback, generateDDL, install, and scan.
   rulesSchema	The rules schema.
   dataSchema	The data schema.
   noFailOnError	Set to true or false. When enabled, instances that fail to import are skipped and import continues instead of failing.
   U	Pega user name.
   P	Pega password.
   accessGroup	AccessGroup in which the Rule-Declare-Index of the classes being exposed exists. Applicable for the expose utility if --U or --P are not provided.
