  The Database name [for the *SYSBAS disk group] is established in the 
Relational DataBase Directory Entries (WRKRDBDIRE; ADDRDBDIRE); the name 
corresponds to the "*LOCAL" entry.  Before the Independent ASP, the /the 
system/ was the effective Database; i.e. the database was able to access 
every library.  Since then, there is a Database per iASP.

  Because the design team loathed the idea of having the system ship 
with an undefined Database name, for which some configuration would be 
required to enable the database, the *LOCAL entry would be established 
implicitly with the System Name which also was implicitly established 
from the system Serial Number.  The name for the database of each iASP 
is established from the special value *GEN [I believe on the ASP device 
description], thus the name is /generated/ if not explicitly defined; 
although I believe the /generated/ name is actually just the primary 
iASP name of a disk group, which is just the name of that device.
