If you are working from the latest HEAD and using BDB you'll need to take the following steps to upgrade your BDB databases to work with check-ins as of September 3rd)
[This info can be found in UPGRADE-BDB in the elephant root directory] 1) Install BDB 4.4.20 or later just as you installed BDB 4.3.x 2) Pull the latest HEAD from CVS 3) Update config.lisp and Makefile in elephant root to point to the appropriate directories 4) Rebuild elephant C libraries In the root directory: > make clean > make > make bdb 5) Upgrade your database directory (only log files need updating) >From Sleepycat documentation: 1. Shut down the old version of the application. 2. Run recovery on the database environment using the DB_ENV->open <http://www.sleepycat.com/docs/api_c/env_open.html> method or the db_recover <http://www.sleepycat.com/docs/utility/db_recover.html> utility. 3. Remove any Berkeley DB environment using the DB_ENV->remove <http://www.sleepycat.com/docs/api_c/env_remove.html> method or an appropriate system utility. 4. Archive the database environment for catastrophic recovery. See Archival procedures <http://www.sleepycat.com/docs/ref/transapp/archival.html> for more information. 5. Recompile and install the new version of the application. 6. Force a checkpoint using the DB_ENV->txn_checkpoint <http://www.sleepycat.com/docs/api_c/txn_checkpoint.html> method or the db_checkpoint <http://www.sleepycat.com/docs/utility/db_checkpoint.html> utility. 7. Restart the application. A known good procedure: 1. Cleanly exit lisp/elephant application 2. Run 'db_recover' in database directory using 4.3 tools 3. This will remove the environment 3.b (optional) Run 'db_checkpoint -1' and 'db_archive -d' to checkpoint and update db files to latest log. This will snapshot the DB and allow you to backup less data, but it makes catastrophic recovery to any time before the snapshot impossible as you are deleting history with the '-d' option so exclude that if you are conservative or aren't sure what you're doing. 4. Copy your database files and all log files to a backup 5. Run 'db_checkpoint -1' using 4.4 tools (ignore error message) 6. Restart lisp, reload application and ensure that the latest elephant source has been fully recompiled 6) Connect to your DB, all should be well! This procedure worked for my Mac OS X upgrade from BDB 4.3 using the latest HEAD on a very large, complex DB. _______________________________________________ elephant-devel site list elephant-devel@common-lisp.net http://common-lisp.net/mailman/listinfo/elephant-devel
