Oracle/Unix documentation updated with JDBC instructions for urandom instead of random
Resolved in Pega Version 7.3
The Install/Upgrade guides have been updated to reflect that recent changes to Oracle have created the requirement of forcing the JDBC driver to use /dev/urandom instead of /dev/random to improve security as well as connection open and close performance. The guide now recommends customers running Oracle on Unix do one of the following: 1. Update $JAVA_HOME/jre/lib/security/java.security to use securerandom.source=file:/dev/./urandom 2. Set system property -Djava.security.egd=file:///dev/urandom

Reference to outdated property removed
Resolved in Pega Version 7.3
When building a system with WebSphere 8.5.5, DB2 10.5fp7 and Java 8, creating the environment and testing the connection on its datasource produced the warning: "DSRA8200W: DataSource Configuration: DSRA8020E: Warning: The property 'progressiveLocators' does not exist.". This was traced to a code fragment left after that property became unsupported which has now been removed.

Adaptive models update correctly
Resolved in Pega Version 8.5.4
Some models had the recorded responses column updated, but the models (number of Positive, Negative and Processed Responses) were not updated. Investigation showed that deleting the modelRuleConfiguration through the stateManager/client did not delete modelFactories related to the configuration. If a new configuration came in with a different algorithm, the update issue occurred. This has been resolved by reseting the configuration according to its factory in that specific case.

Materialization uses time limit boundary for query
Resolved in Pega Version 8.5.4
After turning on Materialization for pyIHSummary and OfferOutcomesForPast45Days datasets, an SQL query was taking an excessive amount of time and causing multiple alerts in the logs. Investigation traced the issue to database partitioning, specifically that running a query where the pyOutcomeTime range spanned multiple partitions was causing the indexes for all partitions in the range to be opened. To resolve this, the query has been updated with a DSS to support a partition size of min(pxOutcomeTime) to limit the time range to querying day by day, or hour by hour, or any other chronology unit specified. If there are no records for the current limit, then it will look at the next partition. This should prevent the query from needing to open more than 1 or 2 partitions.

Hazelcast remote execution not called from synchronized context
Resolved in Pega Version 8.5.4
After navigating to the Admin Studio portal to view the nodes, the portal was temporarily freezing. Investigation of the thread dump revealed this was caused by a DDS pulse sending a remote execution call to all nodes to update logger settings even though the site was not using DDS. This has been resolved by updating the system to avoid calling Hazelcast remote execution from a synchronized context.

Duplicate key exception resolved for adaptive model
Resolved in Pega Version 8.5.4
During the model snapshot update, a DuplicateKeyException was generated while trying to insert a record in to the predictor table. This did not affect the model's learning, but did appear ion the model monitoring report. This was traced to a local scenario of having the same outcome values defined on the model with different cases (Accept and accept). All predictors used in an Adaptive model are inserted into the model monitoring tables as a part of the monitoring job: because the monitoring tables are not case sensitive, this lead to a unique constraint exception since there were multiple IH predictors with the same name. To resolve this, validation has been added which will skip adding duplicates from new responses.

Upgraded Apache UIMA Ruta libraries to resolve memory leak
Resolved in Pega Version 8.5.4
A memory leak issue that resulted in a reboot being needed every few days was traced to the class org.apache.uima.ruta.rule.RuleMatch. This has been resolved by upgrading the Apache UIMA Ruta libraries to v2.8.1. A high level of exception logging may be seen under high loads due to annotations in the standard Ruta scripts; this will not impact execution and further work will resolve this in a future release.

Corrected unreleased database connections
Resolved in Pega Version 8.5.4
When using a custom activity that calls Dataset-execute on a database table dataset, the DSS Pega-Engine.prconfig/classmap/usemergestatement/default was set to false and the prepared statement for a database table dataset was failing. Upon the failure, an exception was generated that prevented the database connection from being released. This has been corrected.
