1.4.6 Running Processing Jobs Under a Username Other than SYSTEM on OpenVMS

On OpenVMS, all PMDF processing jobs normally execute under the username SYSTEM. In some environments it can be necessary to change this default. The default username for periodic processing jobs is established when PMDF is installed; the installation procedure prompts for the username to be used.

The username must be that of an account with full privileges, i.e., a privilege mask of -1.

To change to a different username after installation, redefine the system-wide, executive-mode logical name PMDF_BATCH_USERNAME to translate to the desired username and the system-wide, executive-mode logical name PMDF_BATCH_ACCOUNT to translate to the corresponding accounting field. The next step is to edit the two files SYS$STARTUP:pmdf_startup.com and PMDF_COM:pmdf_submit_jobs.com , and change their definitions of these logical names too. Next kill the periodic PMDF jobs in MAIL$BATCH, in particular:

the periodic delivery job, and
the message bouncer job,

and any other periodic jobs that can be present, depending on just what components of PMDF you are using, such as:

the popstore message bouncer job,
the PC channel polling job, and
the DECUS UUCP return job.

Such periodic jobs must be killed (since if left alone they would continue to resubmit themselves using the SYSTEM username) and then resubmitted afresh under the new username by executing PMDF_COM:pmdf_submit_jobs.com .
