Thanks John! I tried running db_upgrade, but apparently the utilities were not included in my setup. So I ran the following: gomez@gwnma:/var/www/nd/t1$ sudo apt-get install db4.8-util That installed the utilities, but I'm still having some trouble: gomez@gwnma:/var/www/nd/t1$ sudo db4.8_upgrade -v -h NOID NOID/noid.bdb db4.8_upgrade: Program version 4.8 doesn't match environment version 4.7 db4.8_upgrade: DB_ENV->open: DB_VERSION_MISMATCH: Database environment version mismatch I tried leaving off the environment home flag gomez@gwnma:/var/www/nd/t1$ sudo db4.8_upgrade -v NOID/noid.bdb db4.8_upgrade: NOID/noid.bdb upgraded successfully That looks like it worked. However, when I try making a call to the service I get the old error: gomez@gwnma:/var/www/nd/t1$ curl localhost/nd/noidu_t1?mint+1 no "Env" object (DB_VERSION_MISMATCH: Database environment version mismatch) -Josh On Mon, Feb 13, 2012 at 5:42 PM, John A.
