INC-172859 · Issue 661199

Invalid date handling added to Legacy Adapters

Resolved in Pega Version 8.7

Running the Job Scheduler activity failed with the error "not a valid date/time value". Investigation showed this was caused by LegacyPropertyAdapter.isEmpty being returned as true in case of properties having invalid values, and has been resolved by adding handling for an InvalidValueException in LegacyPropertyAdapter and LegacyPageAdapter.

Handling added for multi-node concurrent access to conclusions

Resolved in Pega Version 8.7

A proposition update was triggered and heap memory jumped up and a thread dump was generated. A Pega0004 error was also generated at the same time. Investigation showed that many queries were getting fired on pr4_rule_sysgen table in a multi-node environment during RAP import. This caused database contention as more than 80 nodes were trying to load conclusions simultaneously. To resolve this, an update has been made to run an agent periodically to save conclusions into the database. This agent is configured to not run on multiple nodes simultaneously, which will avoid database contention issues from conclusions.

Pushservlet cookie path updated to resolve error

Resolved in Pega Version 8.7

A very large number of exceptions were being logged indicating "Unhandled error in web.request.internal.URLComponentProcessorImpl.populateCSRFToken", impacting the ability to perform log analysis. This exception has been resolved by updating the pushservlet cookie path.

Performance improvement for Application Save: Node Level Data Pages

Resolved in Pega Version 8.7

As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

Error message updated for data page with REDUX

Resolved in Pega Version 8.7

A WrongModeException was generated when a runtime activity was trying to access a missing property in a data page with REDUX enabled. To clarify the issue, the error has been modified to be a MissingPropertyException. In addition, property information for a page group property was inferred on the top level page when it should have been inferred on the embedded page. This has been changed to infer the correct property information for mode-based processing to work as expected.

INC-173895 · Issue 655915

ZMW added to currency codes

Resolved in Pega Version 8.7

The Zambian Kwacha, "ZMW", has been added to the currencies code list in ENCurriencies.xml .

INC-174243 · Issue 655886

Links to specifications persist appropriately

Resolved in Pega Version 8.7

When linking Rules to Specifications, check-ins of some unrelated rules deleted the link. Investigation showed the deletion happened in the pzHandleLinksPostCheckIn activity, and was caused by an empty parameter page name that caused pcInsKey to not have a value, so all links returned by "Obj-Browse" were later deleted. To resolve this, an update has been made to insure the "Pass current parameter page" option in step 2 of the Connect REST PostCheckIn activity is enabled so that the downstream activity pzHandleLinksPostCheckIn behaves as expected.

INC-174652 · Issue 654140

Case Archive updated to better prune email and attachment metadata

Resolved in Pega Version 8.7

After configuring pyPegaArchiver, pyPegaIndexer and pyPegaPurger to remove old cases, there were no records present in the pr_metadata table but the records related to Data-Corr-Email, Data-WorkAttach-File and Link-Attachment remained. As there is no harm in removing these entries because the system has already copied the reference to these attachments, the entry in pr_metadata can be removed without any issue. With this update, external and shared entries now get removed from pr_metadata table when a purge is performed, however they do not get removed from the target table.

INC-174694 · Issue 650781

Check added to ensure read locks are released

Resolved in Pega Version 8.7

Read locks were not being properly released if a thread was holding a read lock and the system encountered an issue such as an out of memory condition. To resolve this, an update has been made to DeclarativePageDefinitionCacheImpl which will check whether a thread holds any read lock before trying to acquire a write lock, and if so release all the read locks held by that thread.

INC-174716 · Issue 656441

Updated handling for validating/saving circumstanced rule on branch

Resolved in Pega Version 8.7

Using 'save as' for an already circumstanced rule with a new property/template caused the Rule-.DictionaryValidation activity to register the error "StandardValidate-CircumPropAlreadyDefined". The same activity Step did not throw an error when saving into Branch. This was traced to the ruleset name not being the same for the branch ruleset due to having _BRANCH_Branch-Name appended to its name, and has been resolved by adding a condition to check for circumstanced rule in a branch.
