HandleResponses updated for use with optimized campaign
Resolved in Pega Version 8.7
After updating from Pega 8.4, responses were not processed in the pxHandleResponses Data flow if the "pyCampaignOptimization" flag was set to true. This was traced to a missed use case for an optimized campaign, and has been resolved by modifying the condition in HandleResponses.

Value Finder updated for use with external Cassandra nodes
Resolved in Pega Version 8.7
Attempting to use the Value Finder feature resulted in the error "Running Simulation is not possible because the required services are not available. Contact your System Administrator to enable the data flow and decisioning data store services." Analysis traced this to a check which identifies whether there is more than one internal node available for CDH/ DSS node. Since there were only external nodes available in this scenario and no internal nodes, the method returned false and returned the error when the CDH / VF page was launched. To resolve this, the check has been modified to allow for external Cassandra.

Special characters escaped for use in "is in List" lookups
Resolved in Pega Version 8.7
After creating a specific criterion on any proposition using a string property, the "Is In List" operator, and a customer list with one value containing a "$", clicking save or check in resulted in the exception error "Problem invoking function: pega_decisionengine_propositionfilterfua.pzPropositionFilterMethodBody--(PublicAPI,ClipboardPage) java.lang.IllegalArgumentException: Illegal group reference at java.util.regex.Matcher.appendReplacement(Matcher.java:857) ". This has been resolved by escaping regular expression control characters in string replacement, which will allow the use of characters such as the $ sign for "is in List" lookups.

Server node cache refresh will use remote execution timeout
Resolved in Pega Version 8.2.4
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.

Interaction History properly saved when running strategy on a different data flow
Resolved in Pega Version 8.7
Customized Interaction History properties that had been added to pyInteractionHistoryConfiguration and pyDefaultWorkingSet and saved into the PR_DATA_IH_FACT table were not being saved properly after upgrading from 7.3 to 8.3. This was a missed use case and has been resolved.

External Input setting available on Strategy Batch Performance Test
Resolved in Pega Version 8.7
It was not possible to specify the External Input as part of a strategy when using a Batch Performance test. This has been resolved by updating the pzDisplayTestStrategyContext When condition to "true" the so external input selector is properly displayed.

Multi-level strategy gives correct rules during Batch run
Resolved in Pega Version 8.7
When using a nested page structure with multi-level strategies that loop through each page and process the customer, a customer with two linked customers A and B had the results of A overridden by B during Batch Processing while single case canvas testing showed the correct results. This was caused by the DSM clipboard page method of carrying the parent page info not supporting the re-use of pages, and has been resolved by adding an enhancement that will sanitize the strategy stage processor to ensure the correct page reference is used.

Unused DSS compiledExpressions now defaults to false
Resolved in Pega Version 8.7
After updating from Pega 8.2 to Pega 8.5, executing a test campaign failed with an error in logs. This occurred when running Distribution tests with "Include funnel analysis reports" checked, and was traced to the DSS setting "decision/strategy/ssaVM/compiledExpressions". As this was previously used to toggle a feature which is no longer in use, the default setting for this DSS has now been changed to false to resolve this issue.

Tombstone cleanup modified to handle very large volume environments
Resolved in Pega Version 8.7
Cassandra nodes were periodically suffering from an out of memory condition. This was traced to tumbling windows creating too many tombstones for Cassandra to clean up effectively when running in a very high volume environment with a short tumbling time. This has been resolved by modifying the procedure away from using individual tombstones to instead use range tombstones which will continuously supersede the previous tombstone so there is never an opportunity for them to build up.

Added handling for MS SQL datestamp format
Resolved in Pega Version 8.7
When using an Microsoft SQL Server, the browse operation was failing with an SQL error for the pyIHSummary dataset. Investigation showed there were some datasets that generated SQL statements with a date timestamp format that SQL was not able to handle implicitly, affecting browsing but not functionality. This has been resolved.
