Hello,
Try to rename the file "default.lck" to "default1.lck"
Project path =>
deployment\data\database\hsqldb\default\default.lck
Hope it helps!
We encountered this error too when starting the app. The issue turned out to be the Java version installed on the laptop.
By selecting a different Java version (17 instead of 11) it was resolved.
Under app setting -> Run time -> Java version dropdown.
Hello Yang Kai
I think Cause of this issue is The most frequent reason is because your application is handling extremely big data sets, either by executing intricate data transformations in microflows or by retrieving a significant volume of data from the database.
Solution:
- Improve Microflows: Examine your microflows, paying particular attention to those that communicate with the database. -Seek methods to: Use XPath constraints to retrieve only the data that is required.
-Data should be processed in smaller batches. Don't put whole tables into memory. -Database Indexing: To enhance query performance, make sure your database tables are appropriately indexed.
-Paging: Use paging to load data in manageable parts when showing lengthy lists of data.
