Mobile features deprecated in 8.4

Valid from Pega Version 8.4

Following the introduction of new functionalities for mobile apps, some features are reaching end of life. To avoid additional effort during updates to future releases, do not use deprecated features.

In the 8.4 release, the following features are no longer recommended:

  • Mobile Client 7 is now deprecated and planned for removal in 8.5. Use Pega Infinity Mobile Client to meet the mobile needs of your business.
  • The Reuse existing web portal functionality is deprecated and planned for removal in 8.5. For improved app performance and more efficient development, use the mobile app builder in the mobile channel. Also, you must convert existing projects to use separate channels for mobile and web portals before upgrading to 8.5.

In addition, the Pega Mobile Express app has been removed from app stores and replaced with the Pega Mobile Preview app.

Context-specific documentation is not available in express mode

Valid from Pega Version 7.1.9

Help topics that are opened from express mode display content that is specific to Designer Studio.

If your system is dedicated to applications that are developed in express mode exclusively, and you do not need Designer Studio help topics, you can set the Online Help URL field on the System Settings landing page to: https://pdn.pega.com/sites/default/files/help_p7e/procomhelpmain.htm. Alternatively, you can view the contextual help system for Pega 7 Express in a separate browser tab.

Design-time limitations in express mode

Valid from Pega Version 7.1.9

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:

Problem with truncating Decision Data Store data set

Valid from Pega Version 7.1.9

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.

Extension attributes are not supported in PMML models

Valid from Pega Version 7.3.1

Models in the Predictive Model Markup Language (PMML) format version 4.3 that contain extension attributes with the x- prefix are not valid. These extension attributes are deprecated; you must use extension elements instead. In addition, if the output type of any output field in the model is set to FLOAT, change it to DOUBLE.

For more information, see PMML 4.3 - General Structure in the Data Mining Group documentation.

The Upload responses action is not supported for adaptive models with customized context

Valid from Pega Version 7.3.1

A default instance of the Adaptive Model rule contains five model identifiers (.pyIssue, .pyGroup, .pyName, .pyDirection, .pyChannel) that are used to partition adaptive models. If you add other identifiers in your Adaptive Model rule instance, you cannot upload responses to this instance with the Upload Responses wizard and the following error is displayed: The Flow Action post-processing activity pzUploadCSVFile failed: Cannot parse csv file.You can still train such adaptive models with data flows.

For more information, see Training adaptive models in bulk with data flows, Model context, and Uploading customer responses.

Upgrading Adaptive Decision Manager data mart tables might fail

Valid from Pega Version 7.3.1

Issue: Upgrade from 7.3 to 7.3.1 fails if the data contained in the pxInsName column of the PR_DATA_DM_ADMMART_PRED_FACT table is longer than 128 characters.

Reason: During the Pega Platform™ upgrade from 7.3 to 7.3.1, data in the Adaptive Decision Manager (ADM) data mart tables is migrated from the PR_DATA_DM_ADMMART_PRED_FACT table to the PR_DATA_DM_ADMMART_MDL_FACT table. In Pega 7.3.1, ADM uses only the PR_DATA_DM_ADMMART_MDL_FACT table where the pxInsName property can store values that are 128 characters long. In Pega Platform 7.3, the pxInsName property in the PR_DATA_DM_ADMMART_PRED_FACT table can store values that are 255 characters long. If the pxInsName property contains values that are longer that 128 characters, the upgrade fails.

Resolution: Issue an ALTER TABLE statement to change the pxInsName column size to 255 characters and resume the upgrade. For example:

ALTER TABLE rules.pr_data_dm_admmart_pred ALTER COLUMN pxInsName TYPE varchar(255);
