[ovirt-users] ovirt-engine ui not showing up/inaccessible

Hi, our office had power outage for more than an hour and continues fluctuations, so i decided to pull the plug after 2nd fluctuation and wait for the power to become stable. After the power became stable, I decided to turn the ovirt-engine up 1st, after booting up. I tried accessing my engine but the webui is not accessible, then i looked at the /var/log/ovirt-engine/engine.log and saw this error: 2016-04-15 06:34:56,265 ERROR [org.ovirt.engine.core.bll.Backend] (MSC service thread 1-28) 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 Can anyone help me out? I need in that environment up for the final stage of my testing. regards, Gene
