There seems to be different options to check if the connection to a database is valid when configuring a data source connection pool in Jboss EAP 6.4.
Is a there a potential conflict or performance implication if all the options are configured at the same time? Like in the example below in colored options
<validation>
<valid-connection-checker
class-name="org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker"></valid-connection-checker>
<check-valid-connection-sql>select 1 from dual
</check-valid-connection-sql>
<validate-on-match>false</validate-on-match>
<background-validation>false</background-validation>
<use-fast-fail>false</use-fast-fail>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"></exception-sorter>
</validation>
