bug of datasource HA for wildfly-8.0.0.Final
My configuration for datasource HA as follows:
<datasource jndi-name="java:jboss/mysql/mysql01" pool-name="back-mysql" enabled="true" use-java-context="true"> <connection-url>jdbc:mysql://10.19.220.198:3306/mysql|jdbc:mysql://10.19.220.199:3306/mysql</connection-url> <driver>com.mysql</driver> <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation> <url-delimiter>|</url-delimiter> <pool> <min-pool-size>10</min-pool-size> <max-pool-size>100</max-pool-size> <prefill>false</prefill> </pool> <security> <user-name>root</user-name> </security> <validation> <check-valid-connection-sql>select * from Student</check-valid-connection-sql> <validate-on-match>true</validate-on-match> <background-validation>true</background-validation> <background-validation-millis>1</background-validation-millis> </validation> <timeout> <idle-timeout-minutes>1</idle-timeout-minutes> </timeout> </datasource>
I stoped mysql:10.19.220.198,and accessed my page.
But it worked wrong,still connected to 10.19.220.198.
