If you are installing and configuring Commerce Reference Store, the URL connection prompts are incorporated into the CIM script that Commerce Reference Store uses, via the following two options in the DEPLOY CRS ENDECA APP menu:

Enter the hostname of the ATG server to retrieve the user segments.  This usually
is the CA/Merch server. [[localhost]] >

Enter the port of the ATG server to retrieve the user segments.  This usually is
the CA/Merch server.  Typical values are 7003 for WebLogic,8080 for JBoss and
Tomcat, and 9080 for WebSphere. [[7003]] >

When CIM executes the deployment template, it uses the values specified for these two menu options to populate the deployment template prompts.
