Hello everyone!
in Design Studio
- After 5-10 minutes not working with DS (connected to HANA) I return back and try Add a new Data Source or activate the Content assistancein scripts, application freezes for a minute and logs the following error (see below).
- The same thing, when I try to work with my Design Studio application in the browser after a 5-10 min idle.
in HANA Studio
- I may Open Data Preview of the table and when I Refresh this view after 5 min it freezes HANA Studio for 1 min.
- in SQL Console: after 5 minutes idle I execute sql query, it freezes for 1 min and returns with an error
"Cannot get the data provider outline
Data receive failed [Read timed out]."
My assumption:
Could it happen because of my (default) HANA database configuration, like idle_connection_timeout ?
I tried setting to "15000" or "-1" didn't help: How can I keep DB connection always alive in HANA Studio? - Stack Overflow .
My installation:
DS 1.4
HANA SPS8 @ Azure
Have anyone had these issues?
