Using the Database Utilities

DBLOAD

Loads data entries from the backup volume(s) created by the DBUNLOAD utility into data

sets of the database.

Operation

1 [:FILE DBLOAD[=filename] [;DEV=device] ]

2 :RUN DBLOAD.PUB.SYS

3 WHICH DATABASE? database name [/maint word]

WARNING: The LANGUAGE of the database is DIFFERENT from the

language found on the DBLOAD MEDIA. Continue DBLOAD operation?

(Y/N):

4 DATA SET m: x ENTRIES

5 END OF VOLUME n, y READ ERRORS RECOVERED

6 DBLOAD OPERATION COMPLETED

END OF PROGRAM

(Refer to "Operation Discussion" later in this section.)

The volume(s) must have been produced by the DBUNLOAD program, and the database name

on the volume must be exactly the same as the database name, or root ﬁle name, in the

current session or in the group and account of the job. DBLOAD issues an error message if

the database name or maintenance word speciﬁed is different from the DBUNLOAD ﬁle. In

addition, DBLOAD checks that the group and account speciﬁed is the same as that in the

DBUNLOAD ﬁle. To reload the identical data into the database, the DBUTIL ERASE command

must be used prior to DBLOAD unless the database has been purged and re-created.

Executing the >>ERASE command reinitializes the data sets to an empty state while

keeping the root ﬁle and data sets as catalogued MPE/iX ﬁles on the disk.

DBLOAD reads each entry from the backup volume and puts it into the respective data set

from which it was read by DBUNLOAD. If a data set in the receiving database is an automatic

master, no entries are directly put into it by DBLOAD, even though there are entries on the

volume associated with the data set's number. Automatic master entries are created as

needed in the normal fashion when entries are put into the detail data sets related to the

automatic master.
