Check added for invalid operatorID set by autopopulate
Resolved in Pega Version 8.4.4
When an SLA rule attached email reminders, the Link-Attachment table saved the creating operator as System. Upon opening the case perform in Cosmos, all attachments were shown in the utility area and the system tried to show the user name using the pyUserDetails linked property, causing the assignment system to generate a "System is not valid operator" error and the case open failed. To resolve this, the system has been updated to avoid setting the error message on Datapage if an invalid operatorid is passed.

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.

Optimizing helper class enhanced to handle external databases
Resolved in Pega Version 8.4.4
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".

DSS added to set Cassandra query page size limit
Resolved in Pega Version 8.4.4
When a site with a large number of nodes captured responses to the commit log, it was possible for nodes run out of heap space and cause system instability. This was due to the Cassandra query not having a specified page size, so the cluster-wide default setting of 5000 created an issue for large sites which could have over 150 nodes capturing responses. This has been resolved by specifying the page size on the Cassandra query that used to read responses from the commit log. This value will be set dynamically with a DSS to not read more than n responses from all shards combined in a single batch.

Tenant Switching updated
Resolved in Pega Version 8.4.4
When working on new “tenant switching” implementations in a multi-tenant environment, the API itself seemed to be working as expected (case details from another tenant were shown correctly in review mode), but clicking on the assignment unexpectedly opened the case in a new window that contained the same review view of the case rather than the perform view. Clicking the assignment link again caused yet another review window to open with the same issue, over and over. This has been resolved by adding a UI-side update to send the requests on proper sub-domain URL instead of using the parent domain, and by ensuring the document threads are properly deleted for multitenant usecases.

Offline mobile RDL attach updated
Resolved in Pega Version 8.4.4
It was not possible to attach any file using the attach content control while the mobile app was configured as offline and property reference was used for the file name in the attachment control. No issues were seen if a static file name was used. This has been resolved by updating the RDL Attach content handling.

Signature support added for external repositories
Resolved in Pega Version 8.4.4
On Accepting the signature for a repository, saving the case cleared the signature from the control, even though the signature was saved into the data repository. This was a missed use case, and support for signature has been added to external repository use.

CDK key loading modified for better database compatibility
Resolved in Pega Version 8.2.8
Users were unable to log on to the system and received the error "There has been an issue; please consult your system administrator." Investigation showed the log errors stating "(dataencryption.DataKeyProvider) ERROR localhost - Could not get CDK from systemKeyManagementCache - System CDK is null". This was an issue specific to the MS SQL Server database when there were 6 or more CDKs in the database: CDK keys are loaded from database into Cache using an SQL statement which had the ORDER clause. By default, the ORDER clause treats NULL values differently on different databases, and this caused MS SQL databases to not load a necessary CDK key. To resolve this, the SQL query has been modified so the result will be the same for all supported daatbases (Oracle, Postgres & MS SQL Server).
