-For HANA connections, ensure that the HANA client is installed and the correct port number is defined under the Server Name, especially in a multi-tenant environment.
+The credentials used for the connections should have the minimum access necessary for the purpose of the connection. We do not recommend the use of a system admin user such as sa.
-We recommend verifying HANA connectivity by installing HANA Studio in the Versago server.

+===== HANA Connection ======
+===Single Tenant===
+The standard communications port for a **single tenant** HANA database is **30015**.  This is defined during the HANA database setup. The server name field should be set up as <hanaserver>:30015
+===Multi-Tenant===
+In the case where the target database is located in a multi-tenant environment, the actual port to be used must be determined manually.
+To determine the appropriate port, open a SQL Console on HANA Studio for the **Tenant Database** and run the following query.
+<code sql>
+SELECT
+SERVICE_NAME, PORT, SQL_PORT
+FROM SYS.M_SERVICES
+WHERE ((SERVICE_NAME='indexserver' AND COORDINATOR_TYPE='MASTER') or (SERVICE_NAME='xsengine'))
+</code>
+The "SQL_Port" value returned by the query should be used as the port in the Server Name.  In the following image, the tenant is DEVTenant.  The query returns port 30047. The connection in Versago is created using this port, rather than the single tenant port 30015 (e.i. <hanaserver>:30047).

+===== VGO Configuration DB Credentials ======
+<WRAP center round important 80% >
+The connection credentials to the Versago configuration DB (vgoCommon) can be update by editing the file **appsettings.Production.json** under the Versago installation path.
