Cassandra 3.11.3 support for Pega Platform

Valid from Pega Version 8.3

Increase your system's reliability and reduce its memory footprint by upgrading the internal Cassandra database to version 3.11.3.

For on-premises Pega Platform™ users, after you upgrade to Pega 8.3, it is recommended that you manually upgrade to Cassandra 3.11.3. You can upgrade to Cassandra 3.11.3 on all operating systems except IBM AIX. If you do not want to upgrade to Cassandra 3.11.3, you can continue to use Cassandra 2.1.20, which is still supported.

For Pega Cloud Services 2.13 and later versions, Cassandra automatically upgrades to version 3.11.3 after your environment is upgraded to Pega Platform 8.3.

For information on how to manually upgrade to Cassandra 3.11.3, see the Pega Platform 8.3 Upgrade Guide for your server and database at Deploy Pega Platform.

Upgrade impact

After an on-premises Pega Platform upgrade, you still have the older version of Cassandra and must manually upgrade.

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

To upgrade Cassandra, you must create a prconfig setting or a dynamic system setting with the new Cassandra version and then do a rolling restart of all the Decision Data Store nodes to upgrade them to the latest version of Cassandra.

 

Data synchronization does not resume after mobile app restart

Valid from Pega Version 8.3

If an offline-enabled mobile app that you build with Pega Infinity Mobile Client is stopped during an initial data synchronization session, the data synchronization does not resume when the mobile app is restarted. Users must not stop the mobile app before initial data synchronization finishes.

For more information about data synchronization, see Offline capability and Guidelines for creating an offline-enabled application.

Text analytics models editing and versioning

Valid from Pega Version 8.3

Pega Platform™ now supports editing and updating training data for text analytics models.

Pega Platform also supports the versioning of text analytics models. When you update the model, Prediction Studio creates an updated model version. You can then switch between the model versions.

Upgrade impact

In versions of Pega Platform earlier than 8.3, the training data for text models was stored in the database. In Pega Platform version 8.3 and later, the training data for text models is stored in Pega Repository. You cannot build new models without setting the repository. After the repository is set, all text models are automatically upgraded and will work normally.

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

After a successful upgrade, set the repository in Prediction Studio before building or updating any Natural Language Processing (NLP) models.  In Prediction Studio, click Settings > Text Model Data Repository.

Text analytics models migration

Valid from Pega Version 8.3

Pega Platform™ now supports the exporting and importing of text analytics models. For example, you can export a model to a production system so that it can gather feedback data. You can then update the model with the collected feedback data to increase the model's accuracy.

Upgrade impact

In versions of Pega Platform earlier than 8.3, the training data for text models was stored in the database. In Pega Platform version 8.3 and later, the training data for text models is stored in Pega Repository. You cannot build new models without setting the repository. After the repository is set, all text models are automatically upgraded and will work normally.

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

After a successful upgrade, set the repository in Prediction Studio before building or updating any Natural Language Processing (NLP) models.  In Prediction Studio, click Settings > Text Model Data Repository.

Number and text input controls on Android devices may not display the correct keyboard

Valid from Pega Version 7.1.8

When running a Pega 7 application on a device using the Android operating system, pxNumber and pxTextInput controls may not display when using the desired on-screen keyboard. This happens when the number or text input type is set to number.

At design time, the input type is selected in the Editable Format section of the Presentation tab in the Cell Properties panel for a pxNumber or pxTextInput control. Due to a known limitation in some versions of the Android OS running on some devices, the keyboard displayed at run time may not support entry of decimal values when a Number type keyboard is specified.

To resolve this issue, use the Phone type when numbers with decimal values may be required. Using the Phone type displays a numerical phone keyboard. The Android phone keyboard includes both commas and periods so that decimals may be entered.

Note that this issue only occurs on Android devices. It is recommended that applications for iOS continue to use type=“Number”.

The Create Build button appears grayed out when configuring and building a mobile application

Valid from Pega Version 7.1.8

When you attempt to configure and build your Android or iOS mobile application from the Mobile tab, the Create build button might appear dimmed. This issue occurs if any of the access roles in the access group were cloned from the PegaRULES:SysAdm4 access role.

Refer to Troubleshooting Pega Mobile Client to learn how to fix this issue in your application.

Decision Data Store data sets can be used only on DNodes

Valid from Pega Version 7.1.8

Data flows that contain Decision Data Store data sets as the primary or secondary source must be created and executed only on DNodes.

Data flows are not restarted automatically after application server restart

Valid from Pega Version 7.1.8

When you restart the application server or the Pega 7 server, you stop the execution of your data flows. The interrupted batch and real-time runs are marked as Failed

Recommendation:

  • Go to the Designer StudioDecisioning > Decisions > Data Flows > Batch processing tab and start the failed batch runs.
  • Go to the Designer StudioDecisioning > Decisions > Data Flows > Real-time processing tab and activate the failed real-time runs.

 

Value list and value group properties are not supported inside data flows

Valid from Pega Version 7.1.8

Value list and value group properties are not supported inside data flows, and you need to instead use other property types.

See the Pega 7 developer help to check all available property types.

Data flow preview size is fixed to 10

Valid from Pega Version 7.1.8

The Preview option for each shape in data flows returns the first 10 records. This value is fixed and currently cannot be changed.
