The installation instructions will refer to the application schema (in which you install the software) as [application schema]. The password for the application schema will be referred to as [application schema password].
Thus when I use an instruction like sqlplus [application schema]/[application schema password]@[database] please replace that with the actual values of your local installation. For example, if you want to install the integration kit into the schema HR with the password hr1 into your local XE instance (having a TNS entry named xe) then this instruction translates to:
sqlplus hr/hr1@xeFor a typical upgrade of an existing schema you don't have to do the installation as SYS. The user already has the proper rights and privileges. All you need to do is to upgrade the schema objects.
