Hi George,
db_checkpoint and db_recover are Oracle BDB XML utilities. I do not how
well they work and how long it would take to run.
It is possible that the repository is corrupt badly due to missing
files. If any file gets deleted accidentally, you may not be able to
recover your database.
Alternately, you could use db_dump and db_load to rebuild your database.
The documentation can be found under "Utilities" at:
http://www.oracle.com/technology/documentation/berkeley-db/db/api_cxx/fr
ame.html

Is there any way to know approximately how long the cold backup should
take? I am running backupofflinerepositories.bat and the CPU has been at
100% for about 20 minutes with the db_checkpoint.exe taking all the CPU.
I see the backupRepositories folder and subfolders but there are no
files in them yet.
Is it possible the repository database is in a state where the backup
does not work? Are there any tools to try and repair it? This is a
development system so if I had to rebuild it from scratch that would not
be a huge loss but it would be good to learn how to fix this sort of
problem.
Thanks
George
