Importing rules and data by using a direct connection to the database

To import rules and data by connecting directly to the database, complete the following steps. This is most commonly done for a stopped instance.

1. For IBM Db2 for z/OS, configure the import properties.

   If you are importing an application with schema changes and a separate DB-Admin-DB-Name and you are using IBM Db2 for z/OS, configure the import parameters before you import the application, or the import will fail. For more information about configuring the import parameters, see IBM Db2 for z/OS: Preparing to import an application with schema changes and a separate DB-Admin-DB-Name. For more information about your application, see your database administrator.

2. Configure the common properties of 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.

3. Configure the required properties of the prpcUtils.properties file.

   Property name	Value
   import.archive.path	The relative path to the archive from the \utils\ folder or the full path to the archive. If the path is a folder, the tool processes all archive files in that folder.
   import.mode	The import mode: import: (Default) Update existing instances and remove duplicates. Use the import.existing.instances property to override this setting. install: Import new instances. Do not import or update existing instances. The log file includes an exception message for each instance that already exists. hotfix : Update existing instances and remove duplicates. If the archive time stamp is older than the existing instance, skip updating the instance or inserting the duplicate.
   import.existing.instances	How the import action handles existing instances: skip: (Default) Skip instances that already exist in different rulesets or versions. override: Replace instances that already exist in different rulesets or versions.
   import.codesetName	The name of the code set to receive the Java .class files.
   import.codeset.version	The code set version to receive the Java .class files, for example: 01-01-01

4. Optional: Configure the optional properties of the prpcUtils.properties file.

   Property name	Value
   import.nofailonerror	Specify whether to continue the import after a failure and skip instances that fail to import. The default is true. Set to false to stop the import if any import action fails. The default is false , which will fail on error.
   import.commit.count	The number of data instances processed with each database commit to balance memory usage and performance. The default of 100 is sufficient for most environments.
   import.compile.libraries	Specify whether to compile libraries after import. The default is true.
   import.allowImportWithMissingDependencies	Specify whether to allow the import to continue even if the archive is dependent on missing products. The default is false.
   import.preserveOrder	Specify whether to import archives in the order specified in the import file. The default is false, which does not enforce any order.
   import.bypassSchema	Specify whether to apply database schema changes during the import. The default is false. If you have already applied the schema changes manually, set this to true.
   import.skipBackup	Specify whether to bypass saving history points and creating restore points during import. As a best practice, leave this set to the default, false, to save history points and create restore points.
   import.enable.defaultcontext	Specify whether to allow triggers for Pega Platform to run while performing command-line imports. The default is false. To allow triggers to run during imports, uncomment this property and set to true.
   import.insecureOperators	As a best practice, and by default, new operators are disabled on import and existing operators are not updated. Setting import.insecureOperators to true does not disable new operators and allows updates of existing operators.
   import.allow.inherited.connections	Specify whether to import inherited database name instances. The default setting is false.
   import.bypass.column.population	If an import adds columns to existing tables, specify whether to bypass automatically exposing and populating the new columns during the import. The default setting is false.
   import.bypass.schema.changes.to.descendant.tables	Optional. If an import changes an existing class, specify whether to bypass automatically making changes to descendent tables. The default setting is false.

5. Save and close the prpcUtils.properties file.
6. Run the prpcUtils.bat or prpcUtils.sh script with the import option, for example:
   prpcUtils.bat import

   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 (example: oracle.jdbc.OracleDriver).
   driverJAR	Location of your JDBC .jar file.
   dbType	Database vendor type (mssql, udb, oracledate, postgres, 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.
