Optimizing helper class enhanced to handle external databases
Resolved in Pega Version 8.6
Running a BIX extract that included a manifest for a target database was resulting in a null pointer exception for the manifest extraction. Attempting to generate the DDL for the manifest table also failed. This was traced to an issue with the helper class using a hardcoded default database for forming the queries, causing it to ignore the database config/DADN/prconfig for the Oracle database and form a query using the PegaRules' database credentials. This only occurred when trying to do external database operations on a different database platform; Oracle PegaRules worked as expected with an Oracle external database and Postgres Pegarules worked with a Postgres external database, but mixing Postgres PegaRules and an Oracle external database would result in the null pointer exception. To resolve this, the helper class has been enhanced to work with external databases by passing the database name as a parameter so it will properly calculate the query based on the type of target. An error in the name of the class has also been corrected, and is now available as PerformanceHelper rather than the previous "PerformaneHelper".

Improved resolved rules cache
Resolved in Pega Version 8.6
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.

Additional DSS added to handle Apache client-level timeout
Resolved in Pega Version 8.6
In Connector rule, the system timed out a connection after 1 hour even after a connection time timeout was configured to be 30 seconds. Apache's refactoring of their HTTPClient in version 4.3 specifies request timeouts in two ways: on the client-level and on the request-level. Client-level timeouts are enforced prior to and during the handshake, whereas request-level timeouts are enforced after the handshake has been made. Previously, RESTConnector.java and ComponentsHTTPClient.java were configured to only set the user-specified timeout on the request, and not on the client. This caused the client-level timeout to default to "0", or an infinite amount of time. In this reported issue, the remote host closed the connection before the handshake had been completed so the connection remained open for several hours. To resolve this, the DSS "ClientLevelHTTPTimeout" has been added to allow specifying a client-level socket timeout, and ComponentsHTTPClient.java and RESTConnector.java have been amended to assign this value to the client. This DSS is set to 0 by default to preserve backwards compatibility.

Resolved BIX Extract Summary Status Count mismatch
Resolved in Pega Version 8.6
A mismatch was seen between the summary of the Extract Summary Status Count in the Execution History stats versus the logs, for example the execution history saying 98.74% completed while the log says 100% or 100.45% completed. Investigation showed there was mismatch in the query based on the filter value given in the extract rule and the where clause in the query that resulted in an error in calculating percentage in case of any exception. This has been resolved.

Removing Page List removes all cached pages
Resolved in Pega Version 8.6
A previous change was made such that when removing a Page List property, its size is removed from the size-specific cache as well. A further enhancement has been made so that when a Page List is removed, the system will clear the pageCache of all cached pages in the Page List.

Locking and classmap improvements
Resolved in Pega Version 8.6
Threads were getting stuck inside classMap and tableInformationMap, causing nodes to go down. This was traced to issues with class map 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.

Enhancement added to fix corrupted operators
Resolved in Pega Version 8.6
After upgrade, an issues were seen with older operator IDs: it was not able to save the operator ID, switching the portal to admin studio was not working correctly, and it was not possible to launch the case manager portal with the migrated operator IDs. The issues were not seen with operators created after the upgrade. This was traced to corruption in the BLOB, and has been resolved by adding an enhancement to run a utility that will fix the existing corrupted operators.
