Issue/Introduction

You are unable to connect from the Enforce server to the Oracle database using following command in SQLPlus: connect sys/password as sysdba

Cause

Executing this command using SQLPlus on any other server than the Oracle DB server will fail to connect.

Resolution

In a 3-Tier installation (Oracle DB installed on a separate server to the Enforce), the connect command must include the Oracle DB server either using the alias defined in TNSNAMES.ORA or using the connection string from jdbc.properties.
