I am working on HXE 2.0 on Google cloud. Under the XSA cockpit "Tenanat Databases" item, "SYSTEMDB" is enabled for XSA, but not tenant database "HXE", with the "mapped spaces" equal to "SAP(HANAExpress) for "SYSTEMDB".
Well, after I enabled the tenant "HXE" for XSA and moved the "mapped space" to "HXE" and restarted the instance, now the "Tenant Databases" item disappear from the list of XSA cockpit.
Basically, I changed the default to tenant HXE, instead of on SYSTEMDB, and the problem occurs.
How do I get it back? Even though it seems make sense, an afterthought...
