Dear oVirt-Users,
since I had a typo in my engine-setup I did a engine-cleanup, a reboot and
started again.
Unfortunately now the engine doesn't come up any more. Obviously there are
problems accessing the database:
2013-03-05 17:13:08,078 ERROR [org.ovirt.engine.core.bll.Backend] (MSC service
thread 1-32) Error in getting DB connection. The database is inaccessible.
Original exception is: DataAccessResourceFailureException: Error retreiving
database metadata; nested exception is
org.springframework.jdbc.support.MetaDataAccessException: Could not get
Connection for extracting meta data; nested exception is
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC
Connection; nested exception is java.sql.SQLException:
javax.resource.ResourceException: IJ000453: Unable to get managed connection
for java:/ENGINEDataSource
I already tried:
yum erase ovirt-engine
yum earse postresql-server
and installed it again, but it didn't help.
Does anyone have an idea?
Best regards and thanks in advance
Dennis
In the /etc/sysconfig/ovirt-engine file you should have the details of
the connection to the database, in particular you should have something
like this:
ENGINE_DB_URL=jdbc:postgresql://localhost:5432/engine
Are you using "localhost" as in this example? If that is the case then
check that the database is listening in right address and port:
# netstat --listen --tcp --numeric --program | grep postgres
tcp 0 0 127.0.0.1:5432 0.0.0.0:*
LISTEN 10424/postgres
Then also check that connection to the database is working:
psql --host localhost --port 5432 --user engine --password engine
Password for user engine:
psql (9.2.3)
Type "help" for help.
engine=>
You may also run a simple query to check that the tables are there:
engine=> select count(*) from vdc_options;
count
-------
346
(1 row)
Hopefully, if there is an error, the output of these commands will give
you a hint.
