QlikSense Oracle Data connection performance tuning suggestion

Hi Team ,

Using QlikSense February 2022 release patch 15 and while creating oracle data connection I have enabled the Use Bulk Reader option in the Oracle data connection and configured the Max String Length parameter to 16384 to handle large text fields efficiently. Reload time is faster . But I need suggestion whether it's correct approach or not ? If not then what can be followed?

Regards,

Koushik

Are you using the driver provided by Qlik or the ODBC driver provided by Oracle client ?

What is the version of the Oracle Client and Oracle Database ?

Do you really have fields with large text ?
