Hotfix hashmap cleanup improved
Resolved in Pega Version 8.1.7
A DL installation failed with an out-of-memory error. It was observed that many CacheEntry(VersionedJdbcJarRwader.java) hashmaps were being created to store the details for each hotfix but that were then never cleared. This has been resolved by adding the finally block in CodeImportProcessImpl.java class to call the shutdown method for proper cleanup. In addition, the default command line utility (prpcUtils) has been updated to use JVM settings of Xmx 4GB and capture a heap dump if an out-of-memory error is encountered. The auto-generated prconfig.xml has also been updated to leverage its minimal startup setting which will avoid loading the conclusion cache into memory.

Corrected requestor status flag for direct map
Resolved in Pega Version 8.1.7
Numerous "Unable to create requestor" alerts were logged. This was traced to an error in HttpAPI where after retrieving the requestor from the internal requestor map directly, the requestor creation status flag was not set properly. This caused last action to post that alert instead of the correct notice of "existing requestor retrieved". This has been resolved so the flag reflects the correct status.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.1.7
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.

Improved upgrade handling for tables using classes with property references
Resolved in Pega Version 8.1.7
After upgrade, some page property values were blank and exposed database columns did not contain the values. Investigation showed that the reference properties did not have context and hence column population was not able to determine their value. To resolve this, instead of doing column population for all the columns, the system will identify classes that have property references and that are being optimized as part of upgrade process and maintain a list of specific columns to update.

Enhancement added to modify URL encryption for load testing
Resolved in Pega Version 8.1.7
An enhancement has been added which allows conditionally modifying URL encryption for load testing. This uses the flag crypto/useportablecipherforurlencryption: if true, a portable hardcoded key is used to encrypt the URLs and if false, a dynamically generated key per thread/requestor is used to encrypt the URL.

Column population honors thread count of 1
Resolved in Pega Version 8.1.7
The thread count parameter in the column population activity was not being honored, causing repeated deadlocks when trying to populate columns. Investigation showed that the ExposeCols process did not honor the thread count when it was 1 (the default is 4), and this has been fixed by adding the necessary code so that if the thread count is 1, it will not run in multhreaded mode.

Modified timestamp query used by ClusterAndDBCleaner
Resolved in Pega Version 8.7.3
The job pyClusterAndDBCleaner was failing with the error "ORA-01861: literal does not match format string". This was traced to the sub-activity pzClearOldQueueProcessorBrokenMessages which was not able to remove broken items with encryption in an upgraded environment due to an incorrect timestamp format passed to the Oracle database. This has been resolved by modifying the query to use a timestamp built using INativeSqlBuilder which will include only the information necessary for the deletion of the item.

Enabled turning off general metrics when queue processing metrics are disabled
Resolved in Pega Version 8.7.3
A memory leak related to QPGeneralMetrics was consuming heap and causing performance issues. Investigation showed queue processor metrics were gathered even when disabled. To resolve this, turning off "General Metrics Handler" while turning off the QPGeneralMetrics has been enabled. Queue processors should now skip the process of collecting general metrics while running activities. This will prevent storing unused (and uncleared) metrics in memory and prevent heap exhaustion.

Improved handling for thread resolution issues
Resolved in Pega Version 8.7.3
Queue Processor/Dataflow was moving to STOPPED state due to failed records in its execution. Investigation showed there was a minor logic issue in the queue processor activity which allowed the Page-Remove step to be called even before the pages were actually created, and this has been resolved by improving the recovery from a cleared ThreadContainer which might cause thread resolution issues.
