BLOB decryption API updated for greater flexibility
Resolved in Pega Version 8.4.5
A BIX extraction issue occurred after the class had enabled BLOB Encryption. The errors indicated the BLOB had been persisted in an incorrect stage, causing the extraction of the single item to never complete even though some CSV file was created. This was traced to the API used to read the encrypted BLOB, DatabaseUtilsCommonImpl.getStreamBytes, which had the limitation of decrypting only when a Site-specific cipher existed. To resolve this, the system has been modified to use a different API which works for all encryption modes, PageDatabaseMapperImpl.getStreamBytes().

Zero value parameter handling added to Trend Reporting
Resolved in Pega Version 8.4.5
After converting the Summary Views to a Report Definition, the Chart reporting functionality was not working in the Report Definition drill-down reports; whole records present were being fetched instead of only the graph chart count. Investigation showed that one of the parameters in the FilterBy was missing, and that pxSLAAgeTimeliness used 0 instead of null, causing the system to consider all records. This has been resolved by using the "reporting/useNullForUnqualifiedRecords" DSS setting to handle the 0 value and ensure all parameters are present.

Report title displayed for empty widget charts
Resolved in Pega Version 8.4.5
Per design if there is no data to be rendered in the chart from a report added in a Widget in any portal, a static image is displayed saying "No Data to Display". However, if there were multiple reports in the Widget it caused confusion on which report was not being displayed because the image did not show the title of the report. To resolve this, an enhancement has been added to modify pzRRChartDiv to display the report Title even when there is no data in it.

Local time used for report filters
Resolved in Pega Version 8.4.5
The date format in the filter condition of the report was being displayed in GMT format rather than the Local time Format. This has been corrected.

Added handling for missing deleted/report shortcut for drilldown
Resolved in Pega Version 8.4.5
Whenever “Report Details” for a drilldown report without category was clicked, a Flow Action Error was generated. This was due to a missing Report shortcut normally stored in the Report Definition, and has been resolved by modifying pzPreProcessReportDetails to handle the edge case of a shortcut not present/deleted for a drill-down report.

Search landing page performance improved
Resolved in Pega Version 8.4.5
Performance improvements have been made for the Pega Platform search landing page by implementing timeouts for all requests to ElasticSearch when executing PegaIndexAdminImpl.getIndicesInfo() and changing all requests for single index to requests for all indexes. In addition, SearchUtils.areDummyDocumentsPresent() has been modified to get all 'dummy documents' in case there are duplicate dummy documents in the ElasticSearch indexes.

DSS added for handling missing attachments
Resolved in Pega Version 8.4.5
When an S3 repository was configured as storage, some cases were not coming up in search and exception errors were seen in logs for a deleted attachment after every system restart/re-indexing of the search. Investigation showed these case objects were in the broken queue for pyFTSIncrementalIndexer due to a null pointer error encountered when indexing the attachment, and that the attachments were available in the repository but could not be read from the attachment repository during indexing. To resolve this, a new DSS setting has been added which allows selecting one of two behaviors: - Pega-SearchEngine indexing/distributed/fail_on_missing_attachment_file = true : broken item is generated, but with a meaningful error message. This is the default behavior - Pega-SearchEngine indexing/distributed/fail_on_missing_attachment_file = false: case is indexed, but without the problematic attachment. Error message is printed out to the logs.

Datatype import updated to handle null value
Resolved in Pega Version 8.4.5
After upgrade, attempting to import CSV files in Data type using the import option provided was not working. This was traced to the AccessPolicy Filter value being set to null in the filterLogic, and has been resolved by modifying the 'if' condition in the NativeSQLSecurityPolicyHelper file to handle an empty value in the logic string of an access control policy condition for a datatype class.

Performance improvements for database queries and archiving
Resolved in Pega Version 8.4.5
In order to improve the performance of database queries, repetitive unnecessary database calls have been removed, archival queries have been simplified, and diagnostic metrics were added. Optional batch requestors have been added to all archival services with their own DSS settings to allow processing more cases in parallel. It is recommended to create 2 additional indexes to help with the archival process. The indexes will be on:pegadata.pr_metadata (pyisparent, pyobjclass, pyarchivestatus) INCLUDE (pyinskey); pegadata.pr_metadata (pyisparent, pyarchivestatus) INCLUDE (pyinskey);
