System Database
The System Database (SysDB) consists of two SQL tables:
MAPDBS to store the description of map databases and associated monitor
processes.
REGISTRY to register a product license and other system-wide default
configuration parameters referred to as globals.
Normally, each system has a single SysDB in the $SYSTEM.ESCSYSDB subvolume,
but SysDB may also be stored on another volume. There should be only one SysDB
subvolume named ESCSYSDB.
You need write access to the SysDB to create or alter the map database, to specify the
product license or alter the default global parameters. You need read access to run
some commands, especially to start the monitor process. Application processes do not
access the SysDB, since application processes obtain all information through the
monitor process.
When NonStop AutoTMF software needs to access the SysDB, NonStop AutoTMF
software looks first for SysDB tables in $SYSTEM.ESCSYSDB. If the tables do not
exist, NonStop AutoTMF software then searches all disks for a SysDB in the
ESCSYSDB subvolume. If there is more than one SysDB, the command interpreter will
terminate with an error.
Although unusual, you can configure more than one SysDB to define different NonStop
AutoTMF software environments on the same system. This is most commonly required
on development systems where different groups with very different requirements share
a system. See Configuring an Alternate SysDB on page A-7 below for details.
