The database format has changed in Berkeley DB XML release 2.3 and existing containers created in 2.x-based applications must be upgraded, and applications should be recompiled.
It is possible to upgrade containers created with 2.0, 2.1, or 2.2. It is not possible to upgrade containers created with a 1.x release of BDB XML. 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:
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.
Depending on the contents, node storage containers may bloat during an upgrade process, resulting in a noticeably larger container. If this is undesirable, it is possible to shrink the size by performing a db_dump and db_load combination on the container, while is it not being accessed by any other programs.
