[jboss-user] [JCA/JBoss] - Datasource failover, sudden disconnection not working

I have a problem using datasource failover with MySQL. My setup is JBoss at host A, and mysql in host B, replicated in host A. I have followed the instructions in JBossJCADatabaseFailover. When I stop mysql at machine B with /etc/init.d/mysql stopfailover works flawlessly, but if I disconnect B's network cable, the application just keeps waiting for the query, and no failover is done. The datasource configuration is: <?xml version="1.0" encoding="UTF-8"?> <!-- $Id: mysql-ds.xml,v 1.3.2.3 2006/02/07 14:23:00 acoliver Exp $ --> <!-- Datasource config for MySQL using 3.0.9 available from:http://www.mysql.com/downloads/api-jdbc-stable.html--> <ha-local-tx-datasource> <jndi-name>PokUpdateDs</jndi-name> <connection-url>jdbc:mysql://192.168.10.219:3306/POK2|jdbc:mysql://192.168.10.210:3306/POK2</connection-url> <url-delimeter>|</url-delimeter> <driver-class>com.mysql.jdbc.Driver</driver-class> <user-name>JBossAS</user-name> MyPassword <min-pool-size>5</min-pool-size> <max-pool-size>20</max-pool-size> <idle-timeout-minutes>10</idle-timeout-minutes> <blocking-timeout-millis>300</blocking-timeout-millis> <exception-sorter-class-name>com.mysql.jdbc.integration.jboss.ExtendedMysqlExceptionSorter</exception-sorter-class-name> <!-- should only be used on drivers after 3.22.1 with "ping" support --> <valid-connection-checker-class-name>com.mysql.jdbc.integration.jboss.MysqlValidConnectionChecker</valid-connection-checker-class-name> <!-- sql to call when connection is created <new-connection-sql>select sysdate() from dual</new-connection-sql> --> <!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers --> <check-valid-connection-sql>select sysdate() from dual</check-valid-connection-sql> <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> <type-mapping>mySQL</type-mapping> </ha-local-tx-datasource> The hosts are: A: 192.168.10.210 B: 192.168.10.219 I could keep playing with blocking-timeout-millis, but I prefer to ask before continue. My question is: What should I have to consider in order to solve this? I mean, get failover working when a database stop working suddenly, not by stopping it cleanly. Thanks.
