Connection verification failed for data source: OWS
[]java.sql.SQLException: SQLException occurred in JDBCPool while attempting to connect, please check
your username, password, URL, and other connectivity info.
The root cause was that: java.sql.SQLException: SQLException occurred in
JDBCPool while attempting to connect, please check your username, password, URL, and other connectivity info
