Workaround for Oracle SMA query timeout
Resolved in Pega Version 7.3
A bug in Oracle can cause an SMA query involving all-constraints to take a long time to execute, which in turn can cause RAP/application bundle imports to hang. The workaround for this is to set the Oracle parameter _optimizer_push_pred_cost_based to false before the execution of the SMA query involving all-constraints, then set it back to true after its execution at the session level.

Consistent Work IDs between case types created in different implementations
Resolved in Pega Version 7.3
Creating an Implementation layer on the Warranty application using the New Application wizard of Pega 7.22 GA was resulting in a different Work ID prefix of some case types like Claim Unit or Appeal than when the same case types were created in the built on application. This was traced to different activities being used to populate the data page, and has been updated to ensure uniform work ID generation.

Check added to ensure Tracer finds regular pages
Resolved in Pega Version 7.3
Page D_Properties was mentioned in pages to trace, it was present in clipboard, but was not passed to tracer due to an error in page handing. An extra check has been added as a fallback to look for a regular page if Tracer's data page check does not return a named page.

Resolved null-pointer exception at ReferencePropertyLinkToCommonParent
Resolved in Pega Version 7.3
When a reference property (liked via top level page) was copied with-in the page (intrapage), an null-pointer exception would be generated by a bad link if the number of levels in the new property differed from the original. The issue was traced to an error in the After Copy duplicator that did not correctly evaluate the target property in all environments. More robust testing has led to refinements on the duplicator to resolve this issue.

New prconfig setting for auto-flipping Oracle optimizer
Resolved in Pega Version 7.3
Severe performance issues were seen while importing a RAP with Oracle 11g and 12c due to an Oracle bug related to SMA queries involving all_constraints. To fix this, the Oracle parameter _optimizer_push_pred_cost_based must be set to false before the execution of the SMA query and set back to true after its execution at the session level. This is not set on the system level since Oracle recommends against it. In order to ease this process, the flag setting can be controlled through the prconfig setting '"database/performance/smaqueryperformanceenabled". This prconfig setting will default to true in order to automatically set/unset the Oracle parameter each time it is needed.

BLOB handling improved for empty properties in HistorySaver
Resolved in Pega Version 7.3
In HistorySaver, using ClipboardProperty.setValue to save snapshot data for the previous version of the rule had the side effect of stripping blank properties from the clipboard page. This caused rules relying on these properties to not be restored correctly. To correct this, special handling has been inserted for the instances History- class and its descendants to serialize blob with EmptyProperties.
