Jboss AS7-verbindingspool maakt geen opnieuw verbinding

Een ding om te onthouden bij het configureren van jboss is dat de beste documentatie soms in de projecten voor de afzonderlijke componenten zit. In het geval van instellingen voor gegevensbronnen, vertel ik mensen altijd om de IronJacamar-documenten te bekijken:http://www.ironjacamar.org/doc/userguide/1.0/en-US/html_single/

voor wat je wilt doen, zouden deze instellingen moeten werken:

<validation>
    <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker"/>
    <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter"/>

    <!-- I don't know what this does but someone on my DevOps 
    team said to set it this way. :) -->
    <validate-on-match>false</validate-on-match>

    <!-- validate the connection using a background 
    thread rather than right before you try to use the connection -->
    <background-validation>true</background-validation>

    <!-- sets the frequency the background thread will check each connection.
    The lower this setting, the quicker it will find a bad connection 
    but it will be more chatty sending the validations to the server -->
    <background-validation-millis>60000</background-validation-millis>

    <!-- fast fail will mark all the connections invalid as soon as 
    it finds a bad one. This will make it clear the pool quicker 
    if all connections are reset at once such as a restart. Fast 
    fail would be trouble though if you had a setup where the database
    sometimes selectively kills a single connection, such as killing long
    running queries. -->
    <use-fast-fail>true</use-fast-fail>

</validation>
