From your messages it appears your running OpenVMS and Ingres 6.xxx. If
you were to look at the II_SYSTEM:[INGRES.FILES]CKTMPL.DEF file you
will see the option WST which is the (WORK,SAVE,TAPE) option. It
normally will point to the command file
This command file by default contains the following commands :-
$ alloc 'p3'
$ dismount/nounload 'p3'
You will want to change this command file, add the /MEDIA_FORMAT switch
to use compaction. If your using a tape loader then I'm sure that the
loader wants to know the labels, VMS can supply these through the
BACKUP command using the /LABEL=(tape1,tape2,tape...) switch. See the
VMS help on BACKUP for more info.
If you want to generate the labels and pass into the ckpdb program
ensure you do something like this...
ckpdb -mtape: db ...
inside the command file CKP_TO_TAPE you can then use the global symbol
tapes_to_use because ckpdb spawns a subprocess which kicks off the
actual backup command.
Hope this is what you were looking for...
