Thanks for your reply. Though, to be fair, a DB admin might also object to including the uuid-ossp extension functions by default on the template DB. That said, it's certainly preferred over full superuser privs :) Cheers, Ian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] New engine install on remote DB fails "uuid-ossp extension is not loaded"
Hi Ian You're right in that superuser privileges are required to make this work. But it would rarely happen that remote DB admin would give you a user with super privileges. The solution we've come up with is this: 1. Use (or tell remote DB admin to do so) the psql command to load the extension functions to template1 DB on remote DB server: psql -U postgres -d template1 -f /usr/share/pgsql/contrib/uuid-ossp.sql 2. Now, all newly created databases will include extension functions. template1 is a special DB in postgres. In fact, when you create a new DB, it is actually copied from template1 with a new name. This way, we can still work with the user that has no superuser privileges in the remote DB server. - Original Message - From: "Ian Levesque" To: "Yair Zaslavsky" Cc: users@ovirt.org Sent: Wednesday, August 15, 2012 12:30:16 AM Subject: Re: [Users] New engine install on remote DB fails "uuid-ossp extension is not loaded" > Here's what the install log tells me: > > 2012-08-14 11:56:12::INFO::engine_validators::425::root:: Successfully > created temp database on server cmcd-web. > 2012-08-14 11:56:12::INFO::engine_validators::443::root:: Checking that uuid > extension is loaded by default on the remote server > 2012-08-14 11:56:12::DEBUG::common_utils::350::root:: running sql query > 'SELECT uuid_generate_v1();' on db server: 'cmcd-web'. > 2012-08-14 11:56:12::DEBUG::common_utils::286::root:: cmd = /usr/bin/psql -h > cmcd-web -p 5432 -U ovirt -d ovirt_engine_test -c "SELECT uuid_generate_v1();" > 2012-08-14 11:56:12::DEBUG::common_utils::291::root:: output = > 2012-08-14 11:56:12::DEBUG::common_utils::292::root:: stderr = ERROR: > function uuid_generate_v1() does not exist > > So, the installer is trying to create a database "ovirt_engine_test" and > succeeding.
