Removed services check and added warnings for simulations
Resolved in Pega Version 8.7.1
Attempting to run an audience simulation resulted in the error "Running simulations is not possible, because the required services are not available. Contact your system administrator to enable the data flow and real-time data grid services". Investigation showed the @DsmServices.pxHasFunctionalNodes("DataFlow","Batch") function call contained in the 'when' rule pyUnavailableDecisionServices was returning false even if all the nodes were in the cluster and all the DSM Services were in NORMAL status. To resolve this, the services check has been disabled and the simulation run will show a warning or fail if a data flow run is queued for more than 30 secs or if there is an issue with querying the underlying metrics storage.

Explicit connectivity close added to Queue Manager error handling
Resolved in Pega Version 8.7.1
Performing a connectivity test on the MQ Connector page with an invalid queue name aborts the test connectivity but the MQ connection was not closing. This can become an issue when using IBM MQaaS (MQ as a service) where only a limited number of connections are allowed. This has been resolved by adding an explicit Queue Manager close in the error handling block.

DSS added to handle merges with lower versions of Postgres
Resolved in Pega Version 8.7.1
After update, executing the batch campaign with volume constraint resulted in the second data flow DF_Wait failing with error message "ERROR: number of columns (1844) exceeds limit (1664)". This was due to the database set’s change (in 8.5) to use the database layer’s merge statement. Prior to that, the logic used "deletes and inserts". Depending on the version of Postsgres, the generated SQL statement for a merge statement is different. The “INSERT … ON CONFLICT … UPDATE” syntax is generated for Postgres 9.5+ AND when there is a PK constraint defined for the DB table. Otherwise, the complex UPSERT statement (old syntax) is generated, as was the case in this issue. This is a known issue in the Postgres server software where it mis-interprets the number of columns involved. i.e., it mistakenly counts the number of columns twice. As a result, the actual maximum columns allowed is only half of the official limit (1664). The same UPSERT statement does not cause the “exceeds limit” exception if there are 832 or fewer columns in the statement. To resolve this, an option has been provided to select between the “original logic” (deletes and inserts) and the “merge statements” logic by way of the DSS “decision/datasets/db/useMergeStatementForUpdates”. Setting “true” will use the merge statement logic, and setting “false” will use deletes and inserts. When the DSS is not defined, the default is "true" and the system will use merge statements in the form preferred by Postgres 9.5+.

DSS added to allow masking of subjectID in alerts
Resolved in Pega Version 8.7.1
In order to allow customizing whether or not a subjectID is included in alerts, a DSS has been added to conditionally mask the subjectID from being logged. To use this, set the "alerts/maskIHsubjectID" DSS in the Pega-DecisionEngine ruleset to true to hide the pySubjectID.

Warnings added to prevent empty StrategyResult page
Resolved in Pega Version 8.7.1
When a Proposition Filter rule refers to a When rule that has "StrategyResult" declared in Pages & Classes but no "Param.StrategyResult", a design time warning will appear to indicate that this might cause discrepancy in globally optimized strategy (GOS) execution. * The warning message for a When rule with StrategyResult in Pages & Classes but not in Parameters: When rule [WhenClass: WhenName] does not have proper mapping for [StrategyResult] page. This would result in an empty [StrategyResult] page being passed into the When rule during execution. Please go to [WhenClass: WhenName] and add [StrategyResult] in the Parameters list and configure the mapping properly on Proposition Filter rule. * The warning message when StrategyResult is not in Pages & Classes but in Parameters list: When rule [WhenClass: WhenName] declares [StrategyResult] in Parameters tab, but isn't used in the conditions. This would affect performance during execution. Please remove the parameter from When rule [WhenClass: WhenName], and remove the Parameter mapping from the corresponding Proposition Filter criteria.
