Enhancements for upgrading in multi-tenant environment
Resolved in Pega Version 8.1.9
Some muti-tenant installations use the same applications or rule instances with the same pzInsKeys for different tenants. This can cause upgrades to time out due to the system fetching all pzInsKeys (which will have duplicates) and working with them in a default batch size of 500 each over 4 threads. This led to the same keys potentially being allocated and processed in different threads, resulting in duplicate processing and timeouts. This has been resolved by updating the select query to fetch the tentantid and pzInskeys in the MT system to avoid duplicate work in multiple threads. In addition, running Generate Declarative indexes fetches the pzinskeys and generates indexes for each record, but before generating, the existing index for the record is deleted and then inserted. Because the delete query to generate the index was not tenant aware, all of the records for the key were deleted for the tenants for that key, but the new index was created only in one tenant. This has been resolved by enhancing the DELETE query to be tenant aware, which will avoid deleting the indexes for all the tenants given an index key.

Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.1.9
A Rules upgrade failed in the Migration step at loadDatabase stage, involving the move of all the table records from old schema to new schema. This was traced to the inability of Migration to load blob of sizes more than 100 MB, and has been resolved by updating Migration to use byte[] to read the blob content with the help of metadata that contains blob length.

TableRenameUtil hashing improved
Resolved in Pega Version 8.1.9
During index name generation, the algorithm that was responsible for index name uniqueness was sometimes insufficient and cerated a loop condition. This has been resolved by using a stronger hash algorithm and refactoring the code that could result in a loop.

Check for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.1.9
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

Handling added for missing expose.accessGroup property
Resolved in Pega Version 8.6.4
After exposing an existing page group and page list properties along with single value properties using a declare index, running the Column Populator tool prpcServiceUtils to populate the historical data resulted in the single value properties being updated in the exposed column properly, but the page group and page list properties were not updated in the declare index table. On new case creation the declare index tables were updated. This was traced to the default expose.accessGroup not being set for the user, and has been resolved by adding a check and handling that will add the missing property in prpcserviceutils.properties defining the access group for the Rule-Declare-Index of the classes being exposed if it is not present.

Warnings pull from report definition page
Resolved in Pega Version 8.6.4
When a report definition filter was used in the "Class instances to include" section of the Product rule, severe warnings appeared noting "Report definition filter performance issues for LookupDataMigration : Using a custom HTML control to format a column may result in poor performance displaying query results. Consider using auto-generated HTML controls". However, the report definition used, LookupDataMigration, has no Custom HTML control in the latest version of the rule, and the "CheckForWarnings" rule for the product was running a report definition in the "Index-Warning" class which has the warnings for all the versions of the rule. This was due to warnings being displayed in the product for the report definition filter without applying rule resolution for report definition, resulting in warnings from all report definition version rules from a ruleset given a report definition name. This has been resolved by adding an update which will use Obj-Open to read the warnings from report definition page instead of looking up for warnings from Index-Warnings table.

In order to support custom trust managers which require an alternate method for supplying the root certificate via a platform trust store, an enhancement has been added to allow Pega Keystore to be used as a hotfix verification source. Detailed information on this can be found in https://docs.pega.com/keeping-current-pega/87/verifying-hotfix-authenticity-using-pega-keystore

Patchdate values made unique
Resolved in Pega Version 8.6.4
The hotfix manager was incorrectly indicating that a previous hotfix was not installed or was partially installed and should be reinstated. This scenario was created during security updates where the missing/incomplete hotfix had been deliberately deleted from the database, and has been resolved by adding an update which will force patchdate to be unique when adding duplicate code resources during tests.
