Dynamic System Setting for selecting clipboard pages implementation
Valid from Pega Version 7.2.1
Create the dsm/clipboard/optimize Dynamic System Setting to select which clipboard pages to use for strategies and data flows in all contexts. Without this setting or with its value set to true, strategies and data flows work on DSM clipboard pages. When you set the value to false, strategies and data flows work on the conventional Pega 7 Platform clipboard pages. This Dynamic System Setting allows you to configure run strategies consistently and obtain consistent results.
For more information, see DSM clipboard pages implementation.
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.
Deploy revisions directly in target environments
Valid from Pega Version 7.3
As a revision manager, you can now directly deploy or migrate completed revisions to multiple Pega 7 Platform environments that were configured as targets by the system architect. The revision management process is faster because you do not need to package a revision as a JAR file, and then manually import that file to the Pega 7 Platform. Additionally, this solution gives business users more control over application rulesets and enables them to act more independently.
For more information, see Direct deployment of revisions.
The UpdateAdaptiveModels agent causes an exception after Pega 7.2 to 7.2.1 upgrade
Valid from Pega Version 7.2.1
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.
Reconfiguration of the Adaptive Decision Manager service after upgrade to Pega 7.2.1
Valid from Pega Version 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.

Batch database processing improvements
Valid from Pega Version 7.3
Batch database processing has been enhanced to ensure that a constraint violation does not occur when you save transactions to a table with a foreign key dependency. Because batch processing changes the order of save operations, it is disabled for transactions with foreign key dependencies. Disabling batch processing ensures that a record with a foreign key dependency on another record will not be written before the record on which it is dependent.
For more information about how batch database processing works and how to enable and disable it, see Batch processing during database write operations.
Improve cluster security by limiting concurrent operator sessions
Valid from Pega Version 7.3
You can increase the security of a Pega® Platform cluster by limiting the number of concurrent sessions allowed for each operator. Because operators typically do not require multiple concurrent sessions for performing their work, limiting the number of sessions reduces the chance that an unknown or untrusted person could access systems in the cluster. Use the new setting Number of concurrent sessions allowed for each operator on the Production tab of the System Data Instance form to configure the number of concurrent sessions for operators. You must restart your system when you change this setting. You can also create a list of operators by using the presence/maxsessions/operators/whitelist Dynamic System Setting, to which the maximum number of concurrent sessions setting will not apply.
For more information, see System form - Completing the Production tab.
Delegation experience in revision management
Valid from Pega Version 7.3
Revision managers can now control rule authoring by assigning a delegation experience to any rule that is part of a revision management change request. Delegation experience types offer different rule authoring capabilities, so the revision manager can select the appropriate delegation experience for the task and the strategy designer’s experience.
File data set
Valid from Pega Version 7.3
You can now create a File data set that reads data from a file that is in CSV or JSON format. You can use this type of data set to test data flows and strategies.
For more information, see Creating a File data set record.
New System Queue Management landing page
Valid from Pega Version 7.3
You can manage your system queues from the new System Queue Management landing page. You can use this landing page to quickly and efficiently debug applications without exiting Designer Studio. In addition to viewing items in a queue, you can defer, remove, and requeue items in a queue, stop items in progress, and view an item's XML.
As a result of this enhancement, the Broken Queue landing page has been removed.
For more information, see System Queue Management landing page.
