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.

High number of busy waits when using Oracle SecureFiles

Valid from Pega Version 7.2.1

You might experience a high number of buffer busy waits when using Oracle SecureFiles for BLOB storage. An Oracle buffer busy wait occurs when a session cannot access a database block in the buffer cache, because another session is either reading the block into the buffer or changing the buffer. As a best practice, use Oracle 11.2.0.4 or later, because earlier versions have more problems with SecureFiles. In addition, to minimize the number of busy waits, set the hidden Oracle parameter _securefiles_concurrency_estimate to 50, and partition the table by using a composite range hash partition that is based on the pxCreateDateTime and pzInskey columns.

For more information, see Troubleshooting: High number of busy waits when using Oracle SecureFiles.

Cannot send mobile push notifications when the Pega 7 Platform is hosted on WebSphere Application Server

Valid from Pega Version 7.2.1

Push notifications are not sent to Android or iOS mobile apps when the Pega 7 Platform is hosted on WebSphere Application Server.

Extract marker file not created at startup

Valid from Pega Version 7.2.1

The extract marker file (PegaRULES_Extract_Marker.txt) is not created at startup, because the rule utility libraries no longer need it. If you used to use the extract marker file to clear the static content file-based cache, to look up lists, or to control starting activities with web nodes, you can delete the contents of the PegaRULES temporary directory instead.

Upgrade/update fails if PostGIS is applied to PegaRULES or PegaDATA schema

Valid from Pega Version 7.2.1

If you use the PostGIS extension to a PostgreSQL database, upgrading or updating the Pega 7 Platform fails if the extension has been applied to either the PegaRULES or PegaDATA schema. PostGIS can be applied to any other schema.

No support for Android versions earlier than 4.4 on mobile devices

Valid from Pega Version 7.3

Pega® Platform dynamic layouts by default now use Flexbox-based rendering. As a result, mobile devices running on Android versions earlier than 4.4 are not supported in Pega Platform. Such devices cannot render correctly with Flexbox because the Pega Mobile Client includes the default stock browser on the Android operating system.

Package caching is not supported in offline-enabled applications built with the UI Kit 7 (09-01-01) portal

Valid from Pega Version 7.3

When you create an offline-enabled application in Pega® Platform, by default, it uses a portal with the UI Kit 7 (09-01-01) ruleset. In such a case, the package caching functionality cannot be used. You must either disable caching on the Advanced tab of the Access Group rule form, in the Offline Configuration section, or use an adaptive design instead of rendering different elements for different devices with the UI Kit 7 (09-01-01) ruleset.

For more information, see Access Group form - Completing the Advanced tab.

Unable to create text analytics models when Java 2 Security is enabled

Valid from Pega Version 7.3

Security exceptions that prevent you from creating text analytics models are caused by the Java 2 Security feature that is enabled at the JVM level. This feature denies access to the text analytics resources that are required for text parsing functions.

Creating a text analytics model results in a failure because of a number of security-related exceptions, for example:

java.security.AccessControlException: Access denied ("java.lang.RuntimePermission""createSecurityManager")

The suggested approach for avoiding this problem is to use the text analytics models that are provided by default, for example, pySentimentModels, pyTelecomTaxonomy, and so on.

For more information, see Text Analyzer.

No video controllers displayed on Android 4.3 and earlier versions

Valid from Pega Version 7.3

When you preview a video clip within Pega® Mobile Client on a mobile device that runs Android 4.3 or earlier versions, video controllers are not displayed in full-screen mode.

Upgrades and updates from Pega 7.3 on MSSQL fail with column name mismatch

Valid from Pega Version 7.3

This failure applies only to upgrades and updates from Pega® Platform 7.3 on systems running Microsoft® SQL Server®. In Pega 7.3, the capitalization for the column name pc_work_agile.pzPvStream is incorrect. The correct capitalization is pzPVStream. To prevent upgrade and update failures, before you upgrade or update, run the following command from the Microsoft SQL Server Management Studio (SSMS) to rename the column:

EXEC sp_rename ‘data-schema-name.pc_work_agile.pzPvStream', 'pzPVStream', 'COLUMN'
