Documentation updated for troubleshooting inline images for email

Resolved in Pega Version 8.5.2

Inline images were not showing by default when sending emails. To assist in this, the troubleshooting information for email has been updated with the following information: Correct configuration for display of inline images via Email bot is one that is shipped standard. To support Rich text in email display via Email bots, Email body must be stored 'As HTML attachment' (the setting on auto generated Service Email rule). In addition, no other setting on listener must be changed especially 'Embed inline images'(should remain unchecked) on Email listener rule. Combination of these 2 settings causes Email bot to save - 1. Email body as attachment 2. All inline images as attachment At runtime UI display, these 2 are recombined to display proper email. This is done in order to increase performance because images are lazily loaded.

Enhancements for upgrading in multi-tenant environment

Resolved in Pega Version 8.5.2

Some muti-tenant installations use the same applications or rule instances with the same pzInsKeys for different tenants. This can cause upgrades to time out due to the system fetching all pzInsKeys (which will have duplicates) and working with them in a default batch size of 500 each over 4 threads. This led to the same keys potentially being allocated and processed in different threads, resulting in duplicate processing and timeouts. This has been resolved by updating the select query to fetch the tentantid and pzInskeys in the MT system to avoid duplicate work in multiple threads. In addition, running Generate Declarative indexes fetches the pzinskeys and generates indexes for each record, but before generating, the existing index for the record is deleted and then inserted. Because the delete query to generate the index was not tenant aware, all of the records for the key were deleted for the tenants for that key, but the new index was created only in one tenant. This has been resolved by enhancing the DELETE query to be tenant aware, which will avoid deleting the indexes for all the tenants given an index key.

Added null checks for RAP extraction

Resolved in Pega Version 8.5.2

After creating a RAP file that Included the History class and adding a List Viewer to filter the instances, no instances were added into the RAP file when trying to preview the product rule. Investigation showed there was a null pointer exception that occurred while acquiring the content page from the clipboard, and null checks have been added to resolve this issue.

Deployment Manager rollback works for directed inheritance

Resolved in Pega Version 8.5.2

Rollback was not working correctly in Deployment Manager for history classes using directed inheritance. This was traced to a redundant check in AbstractHistoryPageKeeper that enforced the history pages pattern inherited from one of the base history classes, and this has now been removed.

Resolved in Pega Version 8.5.2

In order to improve diagnostic information, infoForced loggers have been added for debugging upgrade issues related to JMX calls to enable and disable rules creation.

Initialized entryName for light weight inventory instance

Resolved in Pega Version 8.5.2

When running deployment on a new pipeline created for the next minor version, once the deployment process got to the point of showing aged updates, the “view aged updates” came back as blank screen. Viewing the logs showed the aged update elements come back but were missing the pyName associated with them. Investigation showed that the system did not have support for setting the mEntryName for LightweightInventoryInstance objects. This has been resolved by adding a junit to ensure that getEntryName() doesn't return as null and should be equal to pzInsKey.

Hot Fix Manager updated to use installation order for schema import

Resolved in Pega Version 8.5.2

Schema changes were not being imported during the hot fix manager DL import process. Investigation showed this was due to hotfixes in the DL being iterated over from newest to oldest, causing older hotfixes to replace the value added to a map by the newer. To resolve this, the system has been updated to use hotfix install order, which considers selected and dependent hotfixes, rather than ordering newest to oldest. This ensures that newer table representations will override older rather than the other way around.

Web Tier busy threads released on timeout

Resolved in Pega Version 8.6.1

Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.
