Try using BULDACCT and then modify BULDJOB1 for your purposes.

I have two HP e3000s with the same DTCs configured on both. I noticed when a DTC was re-booted, it downloaded it's configuration, sometimes from one HP e3000, and sometimes from the other. What mechanism is it that tells the DTC to download its configuration from one HP e3000 instead of the other? Can I configure the DTCs to always download from one HP e3000?

The DTC does not request a download from any particular system. It just sounds out a request for download and the first system to answer is whom it listens to, whether that is an HPe3000, an HP9000, or an OpenView DTCMGR workstation.

You can set up SWITCHED ports that will allow the DTC to speak to both systems, but only one system would be the controller. As of MPE/iX 5.5 you no longer need OpenView DTCMGR to set up switched DTCs. However, the key to making all this work is that on the non-controlling HP e3000s, you answer YES to the NMMGR question "Are you using OpenView DTC Manager?". Even if you are not.

The manual you need is Configuring Systems for Terminals, Printers, and Other Serial Devices, which can be found online at http://docs.hp.com.
