Data Flow service in the Pega 7 Platform
Valid from Pega Version 7.2.1
The Data Flow service configuration on the Services landing page now provides a single point of entry for enabling running data flows in batch and real-time modes. To configure the Data Flow service, you must add Decision data nodes on which to run data flows and specify the number of Pega 7 Platform threads that are assigned to process the data flow runs. Additionally, as part of the Data Flow service, you can view the number of active data flows on each node.
For more information, see Services landing page.
HTML5 Visual Business Director (VBD) Planner
Valid from Pega Version 7.2.1
Visual Business Director (VBD) planner has a new look and is now available as an HTML5 web-based application, which replaces the VBD applet version. The new user interface is more intuitive and improves the user experience. You can open the HTML5 version of the planner on all supported browsers (Chrome, Firefox, Internet Explorer 11, and Safari).
For more information, see Visual Business Director.
Performance improvement to BLOB support in Postgres databases
Valid from Pega Version 7.2.2
New tables that contain BLOB columns now use external storage instead of expanded storage for Postgres databases. This improvement applies to tables that are created during installation, upgrade, or during DDL and schema generation. Using external storage improves database performance.
For more information, see BLOB storage in Postgres databases.
Dynamic System Setting for partitioning Interaction History
Valid from Pega Version 7.2.1
Partition keys are used to optimize the retrieval and reading of records that are stored in the Interaction History data set. To define the number of partitions and partition keys for interactions that are recorded in the Interaction History data set, provide a positive integer value for the interactionHistory/numberOfPartition Dynamic System Setting.
For more information, see Interaction History partitions.
Simultaneous editing of propositions in revision management
Valid from Pega Version 7.2.1
When you refine proposition data in Decision Strategy Manager, you can now delegate various propositions that belong to a single decision data rule (for example, multiple propositions from a specific issue or group) to different users. These users can simultaneously edit the proposition data that was assigned to them (the same proposition cannot be part of two open change requests). With this solution, users can modify the proposition data independently, without locking the entire decision data rule for other users while the proposition data is being revised. The ability to view and select all proposition-related data makes it possible to consistently revise not only propositions themselves, but also all associated rules.
For more information, see Proposition-centric revision management functionality.
Easy access to proposition-related rules when creating change requests in revision management
Valid from Pega Version 7.2.1
When selecting propositions for change requests in Decision Strategy Manager, you can view the proposition filter, strategy, and when rules that are associated with the decision data the selected propositions belong to. In addition, you can include those rules in change requests. To view and add any associated rules to a change request, the rules must be part of the application overlay. With the ability to view and select all proposition-related data, you can consistently revise not only propositions themselves but also all associated rules.
For more information, see Proposition-centric revision management functionality.
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.
Unused agents run in background
Valid from Pega Version 7.2
The Update PegaRULES database table statistics agent and the Collect PegaRULES database blob size statistics agent have been added to support future development. These agents run in the background, but they do not do anything. You can, but do not need to, disable them from the Edit Agent Schedule landing page.
For more information, see Agent Schedule form - Completing the Schedule tab.
Automatically manage nodes in a System Management Application cluster
Valid from Pega Version 7.2.2
Instead of manually adding and deleting nodes in a cluster by using the System Management Application (SMA), you can now automatically manage nodes. You can enable Auto Node Discovery and configure it to get information about all the nodes in a cluster, add new nodes, and update the node list.
For more information, see Managing nodes automatically in a System Management Application cluster.
Run advanced agents on only one node in a cluster
Valid from Pega Version 7.2.2
You can now configure an advanced agent to run on only one node in a cluster at a specified time. In addition, you can specify the time interval within which an advanced agent runs on only one node in the cluster, which avoids having two advanced agents starting to run on the same node at the same time.
For more information, see Improved control for running advanced agents and Agents rules – Completing the Schedule tab.
