Resolved thread deadlock for rules upgrade process
Resolved in Pega Version 8.2.6
Platform upgrade was getting hung during the rules upgrade process. This was traced to a deadlock related to the conclusion cache entry for a property needing to make a call to declarative cache, where it tried to hold a read-write lock on a resource that was already locked by another thread. This has been resolved by replacing lock with tryLock to avoid deadlock.

Encoding added for special characters in JFROG filenames
Resolved in Pega Version 8.2.6
A blank screen or the error "Unable to get the file from Repository" appeared when attempting to attach a file from JFROG Repository if the file name contained special characters. This has been resolved by modifying the artificatory URL generation to properly encode special characters during file download.

Performance improvement for queries on Kafka partitions
Resolved in Pega Version 8.2.6
Even though there were multiple dataflow nodes available in the cluster, all requests were going to single node and causing system slowness. Investigation showed there was a queue processor rule that included the pxPartitionKey attribute which forced all records to be sent to a single partition by Kafka producers. This attribute has been removed.

ClusterAndDBCleaner repaired
Resolved in Pega Version 8.2.6
An error in the logic order of events caused a compilation error for pyClusterAndDBCleaner, leading to old records created by the system/node utilities to not be automatically removed as expected. This has been corrected.

Force order added to inner join when running a Rules Resolution filter
Resolved in Pega Version 8.1.7
After upgrade, D_getResolvedWorkStatuses was not loading properly due to a Report Definition that used a Filter by Rule Resolution option timing out on the SQL Server. When the Filter by Rule Resolution option is selected in RD, it will generate a rule resolution query with an inner join which can cause a time out on the SQL Server while it tries to find out the join order for tables with multiple joins. To resolve this, the SQL server will provide a Force order, merge inner join hint option by way of an added DSS reporting/useForceOrderHint. Additionally, reporting/useMergeHintForRRquery should be set on Pega-Reporting to set things up for using the Merge Inner join hint in the query.

Resolved command line BIX/PRPCUtils creating unreachable nodes
Resolved in Pega Version 8.1.7
BIX and PRPCUtils scripts were creating nodes that showed as unreachable or that were never cleared. This was traced to a code change that resulted in nodes starting as stream nodes unless given a node type or DSS settings, and has been resolved by setting the asyncExecutor/enable setting value as false in the prconfig.xml. The BIX command line JVM argument should also be set to NodeType=BIX.

Reinitializing Full Text Search will shut down Elastic Search regardless of search initialization status
Resolved in Pega Version 8.1.7
Pega search was only sporadically working after converting from standard sandbox-marketing to largesandbox-marketing. This was traced to the Full-Text Search initialization having failed on the app-tier node during re-initialization. As part of re-initialization, the existing node is shut down and the Elastic Search node is started. The shutdown process relied on a boolean flag which indicated if the current status of full-text search initialization was successful. In this case, ES was trying to validate all the cluster level settings, for every save of one of the cluster level settings, but could not due to topology changes in the Util Tier node. The boolean flag indicated initialization had failed so the shutdown process was not invoked, yet the system was attempting to start the second instance of an ES node on the same machine. To resolve this, the shutdown FTS code has been modified to shutdown ES regardless of the search initialization status.

pzIsACoverageSessionActiveForThisRequestor moved to @baseclass
Resolved in Pega Version 8.1.7
When logging out, the error "com.pega.pegarules.pub.generator.RuleNotFoundException: Failed to find a 'RULE-OBJ-WHEN' with the name 'PZISACOVERAGESESSIONACTIVEFORTHISREQUESTOR' that applies to 'Code-Pega-List' appeared. This was a log errors issue caused by a 'when' rule not being found due to the temporary Pega step page matching with a locally created page, causing the rule resolution of the 'when' rule to fail. To resolve this, the 'when' rule pzIsACoverageSessionActiveForThisRequestor has been moved to @baseclass.

Added WebSphere Liberty Profile to BaseEnvironment.guessServerEnvironment
Resolved in Pega Version 8.1.7
While trying to add a node to Decision data store nodes via Designer Studio > Decisioning > Infrastructure > Service, the error "Service DDS:** java.lang.NullPointerException" was seen, and it was not possible to add a node or save any configuration. This was caused by an incomplete profile for Websphere Liberty, causing the com.pega.pegarules.priv.context.BaseEnvironment.guessServerEnvironment() API to return 'unknown' as the answer when WLP was used. This has been fixed, and the API will return "Websphere" for Websphere liberty profile as well.

Auto populate disabled during redux page conversion to prevent concurrent modification exception
Resolved in Pega Version 8.1.7
Running a standalone data page sourced from a look up of a class was failing sporadically with a concurrent modification exception. The Data page was backed by redux pages: this meant that when the page fetched from data source was converted to redux page, it was iterating through all properties in the mContent of the page and trying to convert those to redux properties. During this process, when any auto populate property was encountered it was getting triggered and modifying the mContent, resulting in a change in iterator. As a result, when the Iterator was trying to fetch the next element, the concurrent modification exception was thrown. To resolve this issue, auto populate has been disabled during redux page conversion to avoid unnecessary problem during data page load.
