com.decathlon.saml2.security.Saml2SecurityFilter: Technical error occured on
authentication, message=Error getting a connection for pool 'jdbc/permit',
message=Unable to get a physical connection from the database...there are no
connections available.
wg4.bean.ancestor.TechniqueException: Error getting a connection for pool 'jdbc/permit', message=Unable to get a physical connection from the database...there are no connections available.
Solution2: 修改'jdbc/permit'的max_connection,在datasource中一并修改
Solution 3: Restart the OC4J.
