HANA Configuration parameter set to unsupported value

[former_member612721]

Hello community,

Does anyone knows HANA deals with the parameters which have unsupported value set?

I recently found an alert on one of our databases "Configuration parameter system_replication_hostname_resolution set to unsupported value."

In this case, Is the database using the Default value, or trying to use the incorrectly configured value?

Thank you,

Chris

Hi Chris,

Documented in the SAP HANA Configuration Parameter Reference:

The configuration parameter unsupported_configuration_change is available to determine what action to take if an invalid value is set; the parameter can be set to Error, Warning, or None:

• Error - enforces validity by ensuring that invalid values are not set; in this case invalid values are rejected with an error.
• Warning - invalid values can be applied but a warning is generated.
• None - invalid values can be applied but if the parameter was defined with strong validation a warning is generated.
