Query added to find time zone for MSSQL database
Resolved in Pega Version 8.7
The exception "com.microsoft.sqlserver.jdbc.SQLServerException: xp_regread() returned error 5, 'Access is denied.'" was generated when the AES agent PushDBSizeInfo was being run. This was traced to the GetDBInfo activity trying to retrieve the time zone of the MSSQL database by executing a query that used a Microsoft SQL routine to read the windows registry to get the current time zone. The error was not due to security within the SQL Server, but instead was caused by Microsoft Windows security related to the permissions on the registry keys for the users under which specific SQL Server processes were running. To resolve this, an update has been made to call a different query which will get the time zone for the SQL Server.

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.

Some general metrics now disabled by default for better performance
Resolved in Pega Version 8.5.3
While testing decisioning on fnx cloud platform, using a client application to simulate load and using the Stream service with Kafka Instaclustr as a backend, large latency spikes over 1,000 ms were observed at around 33 second intervals from Stream writes. Investigation identified that some metrics that are gathered every 30 sec (on every single node) include a "lag" calculation that requires a heavy process operation during which more threads are spun off, causing CPU spikes. To mitigate this, the general metrics are now disabled by default and can be enabled using DSS.

Data Type local data storage snapshot history updated
Resolved in Pega Version 8.5.3
When a History Class Data object was created, two snapshots were made - one with value and another with no value. This was traced to a 'when' condition that evaluated whether to add history when deleting a record from records editor, and this issue has been addressed by removing the condition as the history-add step takes care of checking if there is a dedicated table or not.

Checks for Apache Tomcat 6 with MSSQL removed
Resolved in Pega Version 8.7
After implementing a specific local Tomcat configuration that removed the Tomcat version number from displaying on Tomcat standard error screens, the error "Tomcat 6 not supported or unable to detect version for custom Tomcat: Apache Tomcat. Contact Pega Customer Support!" appeared and Tomcat failed to start. Because Tomcat 6 was not supported for use with Microsoft SQL Server Systems, Pega used the ServletContext.getServerInfo() method to determine the Tomcat version; if the system used Tomcat 6 or an undetermined version in combination with MSSQL then the system would purposefully not start. As Tomcat 6 is no longer supported in Pega 8.5.2 and above, this check is unnecessary in those versions and the Tomcat version 6 checks in ClassMapImpl have been removed to allow serverAllowsMerge to return as true.

Rule Assembly update for pxTextInput and pxDisplayText
Resolved in Pega Version 8.7
After the application restart, multiple rule assembly alerts were seen for pxTextInput and pxDisplayText . During first access, Assembly is done and container is cached in VTable; investigation showed that in this case, the Load class without the package name had a class not found issue, and then subsequent access tried to use the container from cache and assembly was not done. To prevent this, an update has been made to perform the class lookup using the package name and class name.

Property Rule Form refreshes after discarding changes
Resolved in Pega Version 8.7
After updating from Pega 8.2 to Pega 8.6 and migrating the properties, modifying any property rule and then discarding the change did not refresh the Property Rule Form. Investigation showed that the LOG-SYSTEM-PROPERTYOPTIMIZATION instance created during property optimization was not getting deleted when a property was deleted. As this was not getting deleted, the property was shown as optimized when adding the property back, causing confusion. This has been resolved by cleaning up the LOG-SYSTEM-PROPERTYOPTIMIZATION instance when the property is deleted and there is an optimization entry.
