Oracle handling updated for upgrade DDL

Resolved in Pega Version 8.6

DDL generated for a Pega upgrade displayed the error "ALTER TABLE PC_ASSIGN_WORKBASKET DROP CONSTRAINT GETNEXTWORKINWORKGROUP" when trying to install. This was traced to a change made by Oracle for optimization, and has been resolved by updating the handling for primary key constraint and the corresponding index name.

EnableRedirects property added for REST connections

Resolved in Pega Version 8.6

When implementing a connector with the header “Location” which contains a redirect URI, a 303 response code was expected. Instead, a 400 or 404 error was generated. It was not possible for developers to process the code per their logic in Activity as Connect REST processed 303 responses automatically - i.e. there was no intercept points to implement the suggested approach. To resolve this, the new property "Rule-Connect-REST.pyEnableRedirects" has been added along with a checkbox for the property in "Rule-Connect-REST.pyService" in "Connection" section. Logic has been added in to take value of this property and set it on the HTTPClient being used, and a method has been added to HTTPClient interface and ComponentsHTTPClient to use the new value being passed. The default behavior is the same for the REST Connector, but a client can uncheck a checkbox on the REST Connector ruleform to stop the HTTP client from automatically following any compatible 3xx responses.

Updated SLA table clearance

Resolved in Pega Version 8.6

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.

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, and 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 and 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.

Bad Stream error after passivation resolved

Resolved in Pega Version 8.6

A "Bad Stream" error was seen when attempting to reassign a case to the Workbasket, and a save of the work object failed. This was caused by a corruption of the work object during passivation, and has been resolved.
