RMU/DUMP And DBO/DUMP Extended?

Q: |
I’m confused.
The output from RMU/DUMP and DBO/DUMP
of one of our Rdb and DBMS databases says that all of the areas have
extended one time and I know that they have not extended (the
database was just created). On another database, it says, “Area
has never been extended,” but I know it has extended many times.
Is this a bug in Rdb and DBMS?
|
A: |
It is not a bug, but it is not clear either! The RMU/DUMP and DBO/DUMP report the number of times that a file has extended since it was last created or restored. Thus, if a database with extended storage areas is restored, the “restored count” will be reset when the database is restored. However, if the database file is on a bound volume set, Rdb and DBMS create an extension for each member of the bound volume set. Therefore, if a database is created on a multi-volume bound volume set, RMU/DUMP and DBO/DUMP will display “area has extended n times” even when the database is created. Yes, it’s confusing. |
