The log files are in a different group and on a different volume 
set than the database files. They are none-the-less in the same 
account.  However, I took your meaning and tested its implications 
by creating a logid in the SYS account and assigning it to a 
database in another account and this worked. I clearly 
misapprehended the relationships between log files, log ids, and 
logging processes.

This is odd then:

:getlog atestlid;log=some1001.logs,disc;auto
                     ^
Log file must reside in the logon group and account. (CIERR 1250)
