where:
nodename names the new node in the CDD to contain your personal PARTS
database.
defaultname is your CDD default.
For example:
$ RUN SYS$SYSTEM:DMU
RET
DMU> CREATE DEMONODE
RET
DMU> SHOW DEFAULT
RET
CDD$TOP
DMU> EXIT
RET
$
2. Define CDD$DEFAULT using the defaultname, a period, and the nodename
from step 1. For example:
$ DEFINE CDD$DEFAULT "CDD$TOP.DEMONODE"
defaultname
separator period
nodename

As of Version 7.0, DBMS ships a kit that allows you to choose either a standard
or multi-version DBMS environment.
The multi-version environment is the same as the standard environment, except
that it allows multiple versions of DBMS to exist concurrently on the same
system. This is implemented by adding the major and minor version number to
the image file names, the command procedures that exist in common locations,
and the [.DBM] subdirectory located in SYS$COMMON:[SYSTEST].
To run the demonstration package after a standard installation, (of any version of
DBMS) issue the following command:
$ @SYS$COMMON:[SYSTEST.DBM]DBMDEMO
RET
To run the demonstration package after a multi-version installation, issue the
following command:
$ @SYS$COMMON:[SYSTEST.DBMnn]DBMDEMO
RET
where nn is the DBMS major and minor version.
For example, to run the demonstration package on OpenVMS I64 with DBMS
Version 7.2, issue the following command:
$ @SYS$COMMON:[SYSTEST.DBM72]DBMDEMO
RET
You must run the entire demonstration to create and load the PARTS database.
If you have already created the PARTS database but are unsure of or have
changed its contents, you can reload it by running option 11 of the self-paced
demonstration package. The demonstration package creates the NEW.ROO
database instance. If you have any problems with the demonstration package,
see your system manager or database administrator.
