The way I remember it: For each command typed in, first of all an IEEsomething module gets control whose function it is to determine who should be notified to actually attach the command processor for that specific command. That IEEsomething would know to attach the VARY ucb command processor in master address space, for instance, or the control commands in console address space or wake up the address space that is addressed by a modify command. It has a list of known (system) commands. If the first thing in the typed-in string is what is recognized as a command prefix, IEEsomething would know to address the address space that established the command prefix. Now, a ROUTE command is one of many system commands known to IEEsomething. IIRC, it gets attached in console address space and all it does is send over the command string (minus the ROUTE systemname) to the system addressed in that command string. On the target system, there is also an IEEsomething runnning. It gets the command and does the same deliberation (whom to send it to), just on the other system. What I am fuzzy about is what happens when a command prefix is established (like in the DB2 case) but the actual DB2 system to execute it is down. I thought there would be an error message that the command cannot get executed. On the other hand, I was told that ERLY code can only be established via an IPL, NOT afterwards. The DB2 admins in my last installation were adamant about that. Has that changed?
