Published Release Notes

Improved Clipboard performance

Clipboard performance has been enhanced to use high-speed, read-only data pages, making processing faster. For some high throughput use cases, performance might be degraded. If performance is degraded, you can use a restricted feature set for a specific read-only data page by selecting Restricted feature set for high throughput on the Load management tab of the data page rule.

For information about unsupported features when using a restricted feature set, see High-speed data page support.

Data validation before importing

Data imported into a data type is now validated before it is imported. Validating data before importing it ensures that the data is valid and reduces the amount of time required to manually analyze and validate your data.

For more information about importing data into a data type, see Importing data for a data type.

Simplified deployment of stand-alone Apache Ignite servers

You can now install or upgrade Pega^® Platform in client-server mode, which uses Apache Ignite in a simplified way. The new installation process for stand-alone Apache Ignite servers does not require that you provide database credentials in a text file to communicate with Pega Platform nodes (clients). You provide this information by using JNDI support instead.

For more information, see Apache Ignite client-server clustering topology and the appropriate Deployment Guide.

New alerts for the Apache Ignite cluster

New Pega^® Platform alerts identify issues with Apache Ignite cluster members (nodes) that operate either in client mode or server mode. Refer to these alerts to diagnose problems with the Apache Ignite cluster and to protect against hard-drive failures or loss of data.

The new alerts are:

• PEGA0088: Client node unexpectedly disconnected from the cluster
• PEGA0089: A node left the cluster
• PEGA0090: Cluster segmentation causes subclusters to form
• PEGA0091: Data stored in one or more cluster caches is lost
• PEGA0092: Number of servers in the cluster falls below the recommended settings

For more information about alerts, see Performance alerts, security alerts, and Autonomic Event Services.

Enable different REST service rules for distinct resource URIs

You can now specify different service REST rules for distinct resource URIs. This functionality provides different processing options, request handling, and response handling for each distinct resource URI. Additionally, it eliminates the need to develop and maintain complex logic to handle all possible resource URI paths.

For more information, see Distinct URI specification for service REST rules.

Enable email notifications on agent failure

You can now get email notifications each time an agent fails with a PEGA0010 alert. By receiving notifications on agent failure, you can immediately take action to restart or fix the agent. You can enable email notifications on the Agent Management landing page.

For more information, see Enabling notification on agent failure and PEGA0010 alert: Agent processing disabled.

Download the system state information for a node and the cluster

On the Cluster Management landing page, you can now download a JSON file that contains information about the current system state for a single node or for the whole cluster. You can use this file to compare persisted system state information across time, which can be helpful in debugging system problems. You also can use a new REST API with third-party tools to download the system state file.

For more information, see Downloading the system state.

Select values gadget optimization enhancements

The Select values gadget includes several enhancements that help reduce performance issues when a data set is very large. Administrators and developers can now add and remove optimizations for fields directly in Designer Studio. Additionally, Select values gadgets were added to the proposition import shape and history shape in the Strategy rule form.

For more information about Select value gadgets and field optimization, see Optimizing properties in Select values gadget.

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

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'

Reports on pc_work_agile table fail in Pega 7.3 on MSSQL

This failure applies only to 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 reporting failures on the pc_work_agile table, run the following command from the Microsoft SQL Server Management Studio (SSMS) to rename the column after you install Pega 7.3:

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