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.

Service responses in HTTP and REST connectors are no longer modified

The Pega 7.1.8 release correctly leaves form service responses for HTTP and REST connectors unmodified. Upgrade to this release if you experience a problem in Pega 7.1.7 where service responses for HTTP and REST connectors are modified when the declared type in the Content-Type header is application/x-www-form-urlencoded. In this case, the responses were modified to a base 64 representation of the bytes in the string. In Pega 7.1.8, responses of type application/x-www-form-urlencoded are mapped to the property designated on the Connector record.

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.

IMAGE data type replaced by varbinary(max) in SQLServer

Because Microsoft is discontinuing support for the IMAGE data type, the Pega 7 Platform now supports the varbinary(max) data type, which will replace the IMAGE data type. All new columns in existing tables and all new tables will use the varbinary(max) data type instead of the IMAGE data type, and IMAGE columns will be automatically converted to varbinary(max).

Atom Server and SOAP Server rule forms are deprecated

The Atom Server and SOAP Server rule forms are deprecated. Use the Connect CMIS rule form instead.

Existing rules that were created with the deprecated forms still work, but you cannot create new ones.

The UpdateAdaptiveModels agent causes an exception after Pega 7.2 to 7.2.1 upgrade

After the Pega 7 Platform is upgraded from version 7.2 to 7.2.1, the log files might show an error that is caused by the UpdateAdaptiveModels agent. This agent is enabled by default and is responsible for updating scoring models in the Pega 7 Platform. If you use adaptive models in your solution, you can avoid this error by configuring the Adaptive Decision Manager service. If you do not use adaptive models, disable the UpdateAdaptiveModels agent.

For more information, see Configuring the Adaptive Decision Manager service and Pega-DecisionEngine agents.

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.

Reconfiguration of the Adaptive Decision Manager service after upgrade to Pega 7.2.1

After you upgrade the Pega 7 Platform to version 7.2.1, you need to reconfigure the Adaptive Decision Manager service. Beginning with Pega 7.2.1, the Adaptive Decision Management (ADM) service is native to the Pega 7 Platform and is supported by the Decision data node infrastructure.

Reconfiguration of the Adaptive Decision Manager service after upgrade to Pega 7.2.2

After you upgrade the Pega 7 Platform to version 7.2.2 from a version prior to 7.2,1, you need to configure the Adaptive Decision Manager service. Beginning with Pega 7.2.1, the Adaptive Decision Management (ADM) service is native to the Pega 7 Platform and is supported by the Decision data node infrastructure.
