Use "alternate database" as report source
Valid from Pega Version 7.1.6
You can opt to use the the "alternate database" identified in the Reports Database field of the Data-Admin-DB-Table instance that supports the Applies To class of a report as the source for the report. This reduces the load on the database that serves your application when you run the report.
BIX performance improvements for CSV output in the Pega Cloud
Valid from Pega Version 7.2.1
BIX performance has been enhanced to download up to 25 GB of data per hour for extracts from a BLOB-less class table for CSV output. This high-throughput option is available only for Pega Cloud instances that use a Postgres database. This option is used automatically for these types of extracts.
When this option is used, the –x and –c command-line options for BIX are not supported, and the checkSum field in the manifest summary is not populated. If you need these options, you can revert to the previous implementation by using a setting in the prconfig.xml file.
For more information, see BIX high-throughput data downloads in the Pega Cloud.
Upgrading to Hazelcast 4.x requires downtime during upgrades to Pega Infinity 8.6
Valid from Pega Version 8.6
Upgrade impact statement
On-premises upgrades of Pega Infinity release 8.4.2 and later to version 8.5.1 or later on Tomcat and PostgreSQL are completed with near-zero downtime. However, upgrading to Hazelcast 4.x requires that you shut down and restart your application server.
What is required to update the application to be compatible with this change?
Hazelcast 3.x is enabled by default. For near-zero downtime upgrades, you do not need to perform any action.
For instructions about upgrading to Hazelcast 4.x, see one of the following topics:
- For near-zero downtime upgrades from Pega Infinity release 8.4.2 or later on Tomcat and PostgreSQL, see "Optional: upgrading to Pega Platform version 8.6: Upgrading to Hazelcast 4.x" in Near-zero downtime Upgrade Guide for Pega Platform version 8.4.2 and later for Tomcat and PostgreSQL.
- For all other upgrades, see "Optional: upgrading to Hazelcast 4.x" in the appropriate upgrade guide.
Insights from 8.5 require additional configuration after upgrade
Valid from Pega Version 8.6
Upgrade impact
After you upgrade Pega Platform™ version 8.5 to 8.6, the Explore Data landing page might not include insights that come from the earlier version of the product.
What steps are required to update the application to be compatible with this change?
Run the pxUpgrade85Insights activity to make all insights from version 8.5 accessible for you in 8.6. By running this activity, you upgrade insights with new metadata that is required in version 8.6. For example, the pxUpgrade85Insights activity provides you with the option to set the visibility of insights to private, public or shared.
For more information about insights, see Visualizing data with insights.
Improved indexing of StringList and StringGroup property types
Valid from Pega Version 8.6
Search and Reporting Service in Pega Platform™ 8.5 may improperly index StringList and StringGroup property types. As a result, the data model does not include the affected properties.
Upgrade impact
After upgrading to Pega Platform version 8.6, the system requires that the classes with the StringList or StringGroup type are reindexed.
What steps are required to update the application to be compatible with this change?
On the Search Landing Page, manually reindex all the classes that include properties with the StringList or StringGroup types to ensure that all your data is present in the data model. Alternatively, if finding specific instances of classes is difficult, you can reindex all classes in your application.
For more information, see Indexing class data.
