Batching now enabled when using IH Summary shape in substrategies
Resolved in Pega Version 8.3.1
Batching was not being enabled when using IH Summary shape in substrategies. This was traced to the IH_SUMMARY_CACHE field not automatically being passed to sub-strategies, and has been corrected.

Corrected method IF use with shortcut function
Resolved in Pega Version 8.3.1
After upgrade, method IF was not working as expected when used in an expression like "@if(.totalorders_120days>0,(.remakeorders_120days/.totalorders_120days)<0.3,false)". This was caused by a missed use case for the combination of an exception-generating function in combination with a shortcut function (i.e. ternary, and, or), and has been resolved.

Server node cache refresh will use remote execution timeout
Resolved in Pega Version 8.3.1
A campaign was failing due to VBD remote ping timeout with a stacktrace that indicated a StageException. Investigation showed that when the cluster is heavily loaded, calls to the remote execution API could time out. If this occurred when the VBD client was refreshing its cache of VBD server nodes, then the insert failed and the error was propagated up the calling data flow. To resolve this, the system will use the remote execution timeout when refreshing node cache, extend the timeout to 60 seconds, and ensure timeouts are retried during inserts.

IH summaries working with external Cassandra
Resolved in Pega Version 8.3.1
Summaries were not working for external Cassandra. This was an issue with the IH summary component using the aggregated dataset as a reference, and this fix contains several components to improve this function. An issue where the IH aggregates dataset does not materialize when DDS is external Cassandra has been resolved by modifying the code that checks the DDS availability. A filter that was used to match “” did not work when pre-aggregation is off : this was due to the IH Browse operation being done outside of a DF context, and has been fixed. The IH Summary shape not working properly in a strategy if it referenced an aggregate dataset with pxInteractionID as part of the group-by properties was traced to an issue with it generating a pxInteractionID value when executing the strategy, and has been resolved by excluding pxInteractionID from the group keys in the IH Summary shape.

Added DSS to handle BIX extracts under parse delimiter rules
Resolved in Pega Version 8.3.1
When parse delimiter rules were applied, the File Listener was not parsing the CSV manifest file generated from a BIX extract until the file was resaved. This was traced to a space after a comma in the extracted files, and has been resolved with the addition of a DSS which enables the use-specified delimiter to remove the space after the comma in the manifest files.

Corrected Cassandra startup error related to client authentication
Resolved in Pega Version 8.3.1
During provisioning, Cassandra nodes in PegaDDSTier failed to join the cluster and the error "Exception (org.apache.cassandra.exceptions.ConfigurationException) encountered during startup: Invalid yaml. Those properties [truststore_password, truststore] are not valid" was generated. Investigation showed that the recent addition of support for client authentication using the settings "dnode/cassandra_client_encryption/truststore" and "dnode/cassandra_client_encryption/truststore_password" resulted in nulls being set cassandra.yaml if the new parameters were not given values. To resolve this, truststore and truststore_password will not be added to cassandra.yaml when they are not set in prconfig or system settings.

Filter added to ensure correct context for proposition strategy rules
Resolved in Pega Version 8.3.1
Given two applications (ex App1 and App2) hosted on the same domain where App2 was built on App1, trying to create a strategy rule in App1 and do a test run strategy using the propositional data component which internally uses App2 propositions generated the error: Failed to find a 'RULE-DECISION-DECISIONPARAMETERS' with the name 'GROUP_2'. There were 1 rules with this name in the rulebase, but none matched this request." Investigation showed the strategy was using the PropositionNoCacheUtils and PropositionTools java classes to load the propositions during run time. In these classes, the group classes were browsed from the db irrespective of the application context, causing the strategy run to fail as it was not able to access the decision data rules in other applications which shared the same SR class as the current application. To resolve this, a filter has been added to the PropositionNoCacheUtils and PropositionTools java classes to filter out the groups that are not in the current application context.

Corrected issue with strategy framework testing
Resolved in Pega Version 8.3.1
Issues were seen in creating a dataflow to test the strategy framework shipped with the Pega Marketing product. It was not possible to use a data transform to test this strategy because it is in the shipped PegaMKTEngine ruleset. Investigation showed the value of appliedToClass was retrieved from "pyRunOnDataFlowClassName" instead of from the running strategy, and this has been resolved.

CEP bucket size increased to 1 minute
Resolved in Pega Version 8.3.1
Frequent DSM Data Flow Errors were observed in production nodes with very high event rates. This was traced to the default bucket size for CEP being 1 second for a 31 day window, which was not sufficient to handle high volume use which may create an event strategy window large enough to hit the Cassandra column size limit. In order to resolve this, the default bucket size has been increased from 1 second to 1 minute.

Resolved Transfer to Queue duplicate assignments
Resolved in Pega Version 8.3.1
The Transfer to a Queue option was creating duplicate assignments after accepting the Chat. Once the chat was accepted, an instance was created\maintained in both Assign-Workbasket and Assign-Worklist tables. This happened after adding the "Transfers" queue to an Agent; if that queue was not added, the transfer to a queue option gave an error to the Agent receiving\accepting the chat. The Work-.ReassignDefaults activity is an extension that was customized in the Pega-DecisionManager ruleset for a certain use case in revision management. The customization is no longer required and has become redundant and has therefore been removed to resolve this issue.
