Configuration the Integration solution for SAP Business One

Experts,

I have a scenario where I have 2 servers (1 license and 1 database), where should I install the integration service?

Installed on license server but when I go to configure the SLD company database , does not connect generating the following error

com.sap.b1i.adapter.dia. exception. ConnectionFailedException: Connect to Business One failed.

( -111) Unable to access SBO-Common database

{b1Server=SRVFSA16, SBO_VFSA_Prod=, =licenseServercompanySRVFSA15: 30000, dbType=6, dbUser=sa, userName=B1i}

What information should I put in the fields below

b1Server = database server or license server

license server = licenseServer
