It was just pointed out to me that PeopleBooks does not document how to connect to an application server (3 tier connection) from the command line instead of just directly to the database (2 tier connection) for Application Designer.
So instead of a command line like this which connects you directly to the Oracle instance
pside -CT ORACLE -CD FSDMO -CO VP1 -CP VP1
you’d have something like
pside -CX APPSRV -CX hostname:portnumber -CO VP1 -CP VP1
The -CX parameter is for the host where the application server is running, and the portnumber is the port where the Tuxedo Workstation Listener (not the Jolt listener!) is. This defaults to port 7000 in a demo installation of PeopleSoft.
Connecting in 3 tier with Application Designer is mainly useful for debugging. If you only connect 2 tier, then you can’t debug anything that is happening on the application server.
