The database format has changed in Berkeley DB XML release 2.1 and existing containers created in a 2.0-based application must be upgraded. In addition, applications must be recompiled in order to work with Berkeley DB XML release 2.1.
Existing containers can be upgraded in one of two ways. Using the
dbxml shell facility,
or using the XmlManager::upgradeContainer() method. The shell
program method is simpler.
Once the installation is built, these steps can be used to perform the upgrade:
Make a backup copy of your container.
Assuming the dbxml program is in your PATH, type
dbxml.
dbxml> upgradeContainer <pathToContainer>
dbxml> quit
The upgrade may take a few minutes, depending on the size of your
container. You can check to see if the upgrade was successful by
opening the container with the openContainer sub-command in
dbxml.
