Published Release Notes

Design-time limitations in express mode

Some limitations apply when you develop an enterprise application in express mode. At design time, some features are disabled or have limited options when you configure them in Designer Studio and switch to express mode. The use of these features does not restrict the run-time behavior of your application; however, you cannot change the configuration of these features unless you switch from express mode to Designer Studio.

For more information about each limitation and the recommended action to take, see the following information:

• Pega 7.2.2 Design-time limitations in express mode
• Pega 7.2.1 Design-time limitations in express mode
• Pega 7.2 Design-time limitations in express mode
• Pega 7.1.9 Design-time limitations in express mode

New types of data sets

There are three new types of data sets:

• Facebook - Required for connecting with the Facebook API
• Twitter - Required for connecting with the Twitter API
• YouTube - Required for connecting with the YouTube Data API

Use these data sets when you create instances of the Free Text Model rule and you want to analyze the text-based content on social media streams such as Facebook, Twitter, or YouTube.

Problem with truncating Decision Data Store data set

The Truncate operation for the Decision Data Store data set may cause timeout exceptions. This problem is caused by the Apache Cassandra database that waits until compaction tasks finish before it can truncate the data set.

Recommendation:

Repeat the Truncate operation until it is successful.

End of support for Netscape Plugin API in Google Chrome 45

Beginning with Chrome 45, which is expected to be available in September 2015, Google is ending support for browser plug-ins that rely on the Netscape Plugin API (NPAPI) architecture. These plug-ins include Microsoft Silverlight, Adobe Flash Player, and Java.

The Pega 7 Platform includes several optional features that use these plug-ins. For a detailed overview of these features, see Client-side technologies.

PegaDISTRIBUTION Manager (PDM) is no longer available

The PegaDISTRIBUTION Manager (PDM) is no longer available in the Pega 7 Platform. The related PDN articles and help topics have been archived.

New property pxSaveDateTime

A new property, pxSaveDateTime, records the date and the time that an instance was saved with business changes to the database. This property is always used when an instance is saved, whether you are creating an instance or updating an existing instance. This property is not updated when an instance is moved from one system to another, and it is not updated during certain system management operations that do not change the content of the instance, such as column exposure.

Primary key constraint error when using JBoss

A primary key constraint violation exception might occur in the following situation: you use JBoss EAP 6.4 and SQL Server 2012 with a JDBC 4 driver, and you use two or more file listeners or JMS MDB listeners with concurrent threads that create work objects that use multiple files. If a primary key constraint violation exception occurs in this situation, update the data source configuration file to set the jta parameter to true. For example, set <datasource jta="true" jndi-name-"java:/jdbc/PegaRULES>.

Support for rule rebasing

You can now rebase the rules on your development server with the most recently committed rules from a centralized system of record (SOR). For example, after rules are merged on the SOR, you can rebase your development application to refresh your application with the merged rules. Development teams working in two separate development environments can share their changes, keep their local rulebases synchronized, and reduce the probability of conflicts with other development teams.

For more information, see Rule rebasing.

Support for Apache Cassandra

The Pega^® Platform can now read data from and write data to an Apache Cassandra database. Apache Cassandra is a NoSQL database that you can use when a NoSQL database better meets your scalability and processing requirements.

For a list of supported and unsupported features, see Apache Cassandra support.

WebSphere log error with Java 8 for Enterprise JavaBeans

For environments that are deployed by using Java 8 on IBM WebSphere Application Server version 8.5.5.9 through the last 8.5.5.x fix pack, the log might report that a class was not found when the application server attempts to start Enterprise JavaBeans. If Java EE functionality is not needed, no further action is required. However, to use Enterprise JavaBeans, see WebSphere log error with Java 8 for Enterprise JavaBeans.
