PegaUnits bulk testing updated
Resolved in Pega Version 7.3
AUT test cases were failing while running in bulk, though running a single unit worked as expected. This was found to be a conflict with the way a test case uses a current parameter page from the start of execution to end of execution and then passes it to the next test; if there are two data page test cases where one is configured to have a non-blank value for a given parameter while the second one has a blank value for same parameter, the second test unexpectedly encounters the non-blank value. To resolve this, the code has been modified to reset the value of only RUT params before set up is called, so that every test case behaves truly independently.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.6.1
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.

Stricter criteria set for reusing an SSAExecutionContext
Resolved in Pega Version 8.6.1
After a Strategy was configured with an existing Proposition Filter and the Explain Results box was unchecked, executing the strategy resulted in the error "Stack is empty, cannot pop any more frames". Investigation showed that the SSAExecutionContext object was reused across the two criteria evaluation in Proposition Filter rule: this works well as long as the input is the same across the two evaluations. However, the SSAExecutionContext object also stashed a reference to a PublicAPI object which became stale in the second evaluation and caused the empty stack issue for the given scenario. This has been resolved by providing stricter criteria in deciding when an SSAExecutionContext can be reused or not in the case of Proposition Filter rule.

Support added for cloning SLA agents
Resolved in Pega Version 7.3
The SLA worker agent was not working as expected based on a prior recommendation to clone agents. The cloned agents are not handling any requests. The original agent is still working, but all 3 clones do not perform any work. 6 nodes, for agents per node, and on each node only the original node is working. Cloned agents were not processing work in production if they were duplicated from SLA agents. In order to support this use, a new feature has been added to agent to allow dequeueing pages queued for another agent. This new configuration setting clones Pega-ProCom to multiple custom rulesets or creates a new agent rule in a custom ruleset with multiple rows for the ServiceLevelEvents agent in that rule. Example:

Split-for shape "open flow" works as expected
Resolved in Pega Version 7.3
When working with a flow that contains a Split-for each shape which loops pyWorkParty and executes a flow on Data-Party class, an error was generated if there was a right-click on the sub-flow shape and "Open flow" was chosen. The sub-flow opened properly if there was a right-click on the sub-flow shape, "View Properties" was chosen, then a click on the "Open" icon right of the flow name. This was traced to the Top Class being passed for opening the flow rule in the Navigation rule "pyMenu" of "Data-MO-Activity-SubProcess-SplitForEach" class. To fix this, the class has been changed from Top to ".pyPageClass" in the Navigation rule "pyMenu" of "Data-MO-Activity-SubProcess-SplitForEach" to open the flow rule

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.6.1
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.
