Up and Running with ALLBASE/SQL
Creating DBEFileSets
Before you can create tables and load data into a database, you need to
provide physical file space. Physical files are known as DBEFiles, and
they are grouped together in logical groupings called DBEFileSets.
After the last step, you exited from ISQL, so you must run ISQL again and
connect to the newly created DBEnvironment MUSICDBE. From the ISQL
prompt, issue the following commands:
isql=> CONNECT TO 'MUSICDBE'; Return
Then use the following command to create a new DBEFileSet--ALBUMFS:
isql=> CREATE DBEFILESET AlbumFS; Return
Do not forget the semicolon.
NOTE ALLBASE/SQL upshifts the logical names of objects like ALBUMFS in
the previous example. Thus, even though you enter them in mixed
case (as shown above), they will appear in the system catalog as
all uppercase. (We'll see an example later.)
MPE XL also upshifts all physical file names. Thus, the names of
DBEFiles, log files, and DBECon files (including MUSICDBE in the
previous example), all appear as uppercase in directory displays in
MPE XL, regardless of whether you entered these names in upper,
lower, or mixed case. HP-UX does not upshift file names, so they
appear in directory displays exactly as you enter them. Rembember
that in the CONNECT statement, the name of the DBEnvironment is
case-sensitive in HP-UX, but it is not case-sensitive in MPE XL.
