Simple associations for quickly joining classes

Valid from Pega Version 8.3

Associations now have a simple mode. Use a simple association to quickly and easily join a class to another class. The simple association defines a left join, using a foreign key in the source class and the class key in the target class. Use an advanced association for all other conditions. In addition, simple associations are drawn in the Visual data model reporting mode to visualize the relationships that are available for reporting.

Upgrade impact

The new simple mode draws a map of where all the classes defined in the application rule are drawn as nodes. Relationships between the nodes that are defined by relevant properties are drawn as lines linking the two classes. This feature only includes Case and Data classes that are defined on the Application rule form's Cases and Data tab. It also only includes relevant fields for those classes in order to define the relationships from one class to another.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, add the data and case type classes to the application rule in Dev Studio to have the selected classes appear as a node. In addition, if you want a relationship to display as relevant, set the properties (of the class that defines that relationship) as relevant.

 

For more information, see Exploring the data model.

Association changes after upgrade

Valid from Pega Version 8.3

Associations now have a simple mode. Simple associations are those that join to only one class, use a left join, and have one filter condition to a class key in the target class. Existing associations that define a simple foreign key relationship are upgraded to simple associations when opened; all others are treated as advanced associations. All associations continue to work in reporting.

Making an association simple changes only one piece of metadata; all other data on the association rule is not affected.

Gadget configuration by using IAC gateway console is no longer supported

Valid from Pega Version 7.2.1

The Internet Application Composer (IAC) gateway was deprecated in Pega Platform™ 7.2.1 and is no longer supported. The IAC was used to embed a Pega Platform application, such as a gadget, on the pages of a web application that was located on your intranet, extranet, or internet site.

Upgrade impact

After an upgrade to Pega Platform 8.5, the configuration of gadgets through the IAC gateway console is no longer supported.

What steps are required to update the application to be compatible with this change?

To make subsequent changes to your current web mashup, use Pega Web Mashup. 

For more information, see Tutorial: Creating a mashup with Pega Web Mashup.

Derby databases are no longer supported

Valid from Pega Version 7.1.8

Previously, an embedded Derby database could be used as a file system. This setup was configured by setting storage/class/<<filesystem>>/type to "embedded" in the prconfig file.

After upgrading, storage types that are specified as "embedded" now default to the local file system.

Deprecated rule types

Valid from Pega Version 7.1.8

The following rule types have been deprecated as of the Pega 7.1.8 release:

  • Form
  • Hierarchy
  • Service COM
  • Service BPEL
  • Connect BPEL
  • Parse Transform
  • Parse Transform Collection
  • Parse Infer

For more information, including suggested alternate rule types, see the help topic Deprecated features.

Configuration required for data operations on external schema when using a Postgres database

Valid from Pega Version 7.1.8

When you use the API for data operations on external schema in the Postgres database, you must update the prconfig.xml file. No other platform requires a prconfig.xml update.

To update the prconfig.xml file:

  1. Stop the server and add the following entry to the prconfig.xml file:
    env name="database/databases/postgres_ext/defaultSchema"
    value="externalschema"
    where postgres_ext is the external database that uses the external schema “externalschema”.
  2. Restart the server.

Customizations to the prlogging.xml file must be manually ported after upgrade

Valid from Pega Version 7.3

As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, the name of the logging configuration file has changed from prlogging.xml to prlog4j2.xml and the format of the file has changed considerably. If you customized your prlogging.xml file, port the customizations to the new prlog4j2.xml file. If you do not port the changes, the Pega® Platform uses the default prlog4j2.xml file and disregards your customized prlogging.xml file.

For more information about customizing your log files, see the Apache Log4j 2 documentation.

Socket server has changed for remote logging

Valid from Pega Version 7.3

As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, the socket server that is used for remote logging has changed from the Log4j remote logging package with the LogFactor5 log analysis tool to TcpSocketServer. If you use remote logging, update your socket server to TcpSocketServer. For more information, see Installing and using remote logging.

New process for Pega Cloud customers to obtain BIX extract files

Valid from Pega Version 7.3

The process for obtaining Business Intelligence Exchange (BIX) extract and manifest files for Pega® Cloud customers has changed as a result of data security enhancements for HIPAA compliance. By default, after upgrading to Pega 7.3, you must obtain the BIX extract and manifest files from the Pega SFTP server. From within Designer Studio, you can configure the BIX extract and manifest files to be sent to a remote SFTP server by a file listener. For Pega Cloud customers who have purchased a Pega Cloud SFTP Server subscription, you can configure BIX to send the BIX extract and manifest files to the SFTP server's folders for remote SFTP client download.

For more information about obtaining files from the Pega SFTP server, see Obtaining BIX extract files from the Pega SFTP server.

For more information about having files sent to your SFTP server, see Defining SFTP-related data instances.

Requestor Management landing page access privileges

Valid from Pega Version 7.3

To access the Requestor Management landing page after upgrading to Pega® Platform 7.3, you need to add the appropriate privileges to the @baseclass and Pega-Landing access classes in the access roles. Apply these privileges to any application in which you want the operator to be able use the requestor management feature.

For more information, see the Requestor Management landing page and the appropriate Deployment Guide.
