SAP HANA vulnerability threat report.

The user self-service tools of SAP HANA contain some vulnerabilities and in order to prevent it , we have to update the systems or desactivate the the self-service tool.

In order to to determine wheather the the self-service tool is activated or not, we need to SQL the HANA database and query the folowing:
SELECT NAME, STATUS FROM "_SYS_XS"."SQL_CONNECTIONS" WHERE NAME =
'sap.hana.xs.selfService.user::selfService'

However it is not specified what result to expect if the tool is active, or not. The behaviors that I have so far on different systems are sligtly different.
Sometimes after the query, nothing happen. You go to the the next line. At times you are prompt for a username, others receive the following error:
Password:=*-10709  Connect Failed (No reachable host left).

I would like to know what result to expect when executing above query when self-user tool is active and vise versa.
Thank  you all for the help
