Published Release Notes

Derby databases are no longer supported

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.

Custom database (DB) triggers are dropped during upgrade

The latest version of Pega 7 improves performance by no longer using database triggers to assist with System Pulse and Data-Rule-Summary processing, which is now done within the Pega 7 engine. As a result, DB triggers are no longer installed on either the pr_sys_updatescache or pr4_rule_vw tables.

When upgrading to the latest version of Pega 7, if you had previously implemented a custom database (DB) trigger on these tables, or a custom DB trigger that refers to these tables, it is removed during the upgrade process. No custom triggers are removed unless they reference these tables.

If you have custom DB triggers that reference the pr_sys_updatescache or pr4_rule_vw tables and perform other processing, those triggers must be reimplemented. When doing so, you must be careful to not modify the pr_sys_updatescache or pr4_rule_vw tables.

For more information, see Startup check removes custom DB triggers.

Deprecated rule types

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

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.

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.

Existing operator IDs during upgrades and updates

Upgrades and updates are always performed in secured mode to help prevent unauthorized access to your system. In secured mode, the [email protected] operator ID is always overwritten, but other existing standard operator IDs are not modified. New operator IDs are inserted in secured mode. For more information, see the Deployment Guide for your environment.

BIX -I command-line option fails for unexposed properties

Business Intelligence Exchange (BIX) command-line extractions fail when the extract has a filter that uses unexposed property references that are passed in by the input file that you specified in the -I command-line option. Previously, the BIX extraction ignored the filter and the extraction did not fail.

Upgrade utility for Get Next Work performance

You can run a utility to upgrade Get Next Work processing to more quickly process assignments that were created in versions of the Pega 7 Platform earlier than 7.2.2. Performance is automatically improved on new installations.

For more information, see Upgrading Get Next Work performance.

Pega File Listener process changes

Beginning with Pega 7.2.2, File Listener processes files in a different way:

• File movement in directories – Previously, files were processed from the Work directory. In Pega 7.2.2, files are processed from the source location. Files move to the Work directory only if the initial processing fails and Recovery is disabled.
• New file processing – Previously, File Listener would process all files in the source location, even if the files were added during the processing. In Pega 7.2.2, files added to the source location during processing are read the next time the File Listener starts.

For more information, see File Listener data instances.

Remove obsolete versions of the PredictiveAnalytics-UI and PredictiveAnalaytics-IntSvcs rulesets

After you upgrade the Pega 7 Platform to version 7.2.2, remove the PredictiveAnalytics-UI and PredictiveAnalytics-IntSvcs rulesets from your application as their versions are obsolete. Beginning with Pega 7.2.2, use the Pega-DecisionScience ruleset that contains the latest versions of the PredictiveAnalytics-UI and PredictiveAnalytics-IntSvcs rulesets.

For more information, see About ruleset versions.
