Freeze backup demo comment/correction


I hope that I am reporting this to the right forum!

I have been trying to run the Freeze backup demo under Ice-2.1.0
and Berkeley BD 4.3 on SunOS 5.9.

The "client" program crashed with the following error message:

[ Berkeley DB: DbEnv "backup": incorrect arguments for name-value pair: set_verbose ]
terminate called after throwing an instance of 'Freeze::DatabaseException'

When I checked the SleepyCat Berkeley DB website, I found out that Berkeley DB no longer supports the "set_verbose" method flag DB_VERB_CHKPOINT as of the 4.3 release. (

This flag does appear in the DB_CONFIG file in the "db" directory in this demo.
Once it is commented out, the demo runs correctly.

    Thanks for the bug report! It will be fixed in the next release.

    I should also mention that I could not run the "backup" script under
    the bourne shell. The "$1${i#db}" expression caused the script
    to abend -- apparently this kind of variable manipulation is valid only
    under ksh or bash. When I switched from "sh" to "ksh", the script ran.
