Setting Up the Debugging Environment
You can use the PeopleCode debugger for two-tier and three-tier debugging. The database and application can reside on remote servers; they do not need to reside on the local machine.
Two-tier debugging works out of the box. Setting up three-tier debugging requires you to make a few modifications in PSADMIN (PSAPPSRV.CFG) to enable debugging.
You can connect to a Microsoft Windows NT server domain that is not on your local machine. You do not have to configure a local domain to do this. You also do not have to have PeopleTools software installed locally for three-tier debugging.
Note: Application Designer will not connect to the PeopleCode debugger through a firewall using Network Address Translation (NAT).
