Performance Regression on Oracle Databases

In the release notes of Blueriq 13.6 we attended users of Oracle databases to a performance regression. This regression has been traced back to the usage of case insensitive search. While a permanent solution is being developed, we offer users of Oracle databases a toggle to activate or deactivate case insensitive search. By default, case insensitive search has been deactivated to mitigate this performance regression. If you wish to enable case insensitive search, a page has been prepared to configure the corresponding toggle.

As stated with the previous release notes, this performance regression only occurred in combination with Oracle databases. Users of other database systems have not experienced a performance regression and do no need to implement this toggle.

1. Enhancements

Enhancement Details
List search text internationalization

In the Instance List, the placeholder text of the search field would always be in English. This has been solved. The button now uses a message from the messages*.properties files, with key search.search, which is provided by default by Blueriq.
Feature toggle for case insensitive search on Oracle

We see that the case insensitive search we built can decrease performance in some cases on an Oracle database. For this reason, we disabled case insensitive search by default for now on Oracle. MS SQL Server is not affected. We introduced a feature toggle to enable case insensitive search on Oracle. By default it is turned off.
