Updated SLA table clearance

Resolved in Pega Version 8.4.4

After cases were resolved, SLA entries were not getting cleared from the SLA table. This caused the SLA table to have a huge number of Overall SLA and PendFlow details present for cases that were resolved or moved to the next state, which impacted case processing via SLA Agent. This was traced to SLA queue-items not being removed by delete-deferred as expected, and has been resolved by invalidating the deferred operations and scheduling item removal.

Documentation updated for binary REST response

Resolved in Pega Version 8.4.4

The online help documentation has been updated to clarify the instructions for REST endpoints that return binary data. In some cases, the data is returned in a MIME multipart structure. It can also be returned as the response body. In the latter case, mapping the message body to a java object property will cause the binary data to be mapped as a java byte array value. Mapping the message body to a single value text property will cause the binary data to be mapped as a Base64 encoded text value.

Oracle performance improvement

Resolved in Pega Version 8.4.4

Poor performance was seen when importing a RAP with schemas using Oracle. To resolve this, an update has been made which will set the Oracle tuning parameter at the session level by altering the setting "_OPTIMIZER_PUSH_PRED_COST_BASED"=false before the SMA query involving all_constraints. The setting will be returned to true after the execution of the SMA query. This is controlled through the prconfig setting '"database/performance/smaqueryperformanceenabled" which defaults to true so the setting and unsetting of the Oracle parameter is automatic.

Improved resolved rules cache

Resolved in Pega Version 8.4.4

When Rule resolution iterated over a candidate list to fetch a candidate, performance issues were seen on very large sites. To resolve this, an enhancement has been added that will cache the resolved virtual table entries to optimize performance in high demand use cases like DSM.

INC-131938 · Issue 598479

Locking and classmap improvements

Resolved in Pega Version 8.4.4

Threads were getting stuck inside classMap and tableInformationMap, causing nodes to go down. This was traced to issues with classmap performance and locking, and has been resolved by replacing the lock library with a newer version and refactoring the tableInformationMapImpl class to use a concurrent hashmap instead.

INC-132088 · Issue 603086

Updated Tracer for cluster events

Resolved in Pega Version 8.4.4

When running the tracer from the Admin Studio Listener management landing page, Tracer was always fetching data from one node only even though events were generated on another node. This was due to the specific node where the Listener was running being passed to the concern activity while launching the tracer; the Tracer Client node did not have data to check if the event was being populated on another node, and the result was to always fetch data from one node only even though events were generated on another node. To resolve this, the web node ID where the event is running will be passed.

XML Parse handles dates with time zone correctly

Resolved in Pega Version 8.4.4

Due to a difference in data mapping behavior for Date values, the Parse XML new assembler implementation was incorrectly applying the DateTime type of processing for Date inputs when using timezones and silently ignored the exceptions reported. This has been resolved.

Hazelcast will be used to determine node presence

Resolved in Pega Version 8.4.4

When calling logoff from the end user portal, sporadic PresenceStandardLifeCycleListener exceptions were seen during high load periods. This was traced to changes made in the Service Discovery behavior: when there is an issue with the node and heartbeats are missed, the node goes to Safe Mode. This caused the topology to change and trigger clearing off presence sessions, but the node still received service requests and this issue was seen. To resolve this, an updated has been made so the system will rely on the Hazelcast listener instead of service discovery to determine whether a node has left.

INC-138253 · Issue 597569

Handling added to ensure proper Data-Admin-DB-Table name records

Resolved in Pega Version 8.4.4

As part of property optimization, After exposing the property "SolutionName" using the wizard, the value was not visible in a new column for existing records after the completion of the column population job. This was traced to an issue with DBSchemaDDLExecutor expecting lowercase Data-Admin-DB-Table names, and the wizard has been updated to ensure Data-Admin-DB-Table name records are all lowercase.
