I have 1.8.7 installed.
I run a "yum update" to install the 1.8.8-1 new available stable release.
After I run the install program to configure database : /opt/opennms/bin/install -dis
I got some error while executing even if it displayed a "Installer completed successfully!" at the end.
You can see the log in the attached file "opennms_install_dis.log"
The first error was about a database constraint :
liquibase.exception.JDBCException: Error executing SQL ALTER TABLE datalinkinterface DROP CONSTRAINT pk_datalinkinterface
And after that I was unable to start again OpenNMS :
[root@dtc-srvtest1][/opt/opennms/etc] #service opennms start
Starting OpenNMS: OpenNMS was unable to connect to the 'opennms' database configured in opennms-datasources.xml.
