如何使用Mule JDBC标准重新连接策略

Question

I want to use Mule JDBC Standard Reconnection strategy .... For that I have used the following code :-

 <jdbc-ee:connector name="Database_Global" dataSource-ref="DB_Source" validateConnections="true" queryTimeout="-1" pollingFrequency="0" doc:name="Database">
        <jdbc-ee:query key="InsertQuery" value="INSERT INTO getData(ID,NAME,AGE,DESIGNATION)VALUES(?,?,?,?)"/>
        <jdbc-ee:query key="RetriveQuery" value="Select * from getData where ID=?"/>

 <reconnect frequency="2000" blocking="false" count="5"/> 
 </jdbc-ee:connector>

Now when ever I try to start my Mule application I receive following exception :-

org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'reconnect'. One of '{"http://www.mulesoft.org/schema/mule/jdbc":abstract-query, "http://www.mulesoft.org/schema/mule/ee/jdbc":sqlCommandExecutorFactory, "http://www.mulesoft.org/schema/mule/ee/jdbc":ackSqlCommandExecutorFactory, "http://www.mulesoft.org/schema/mule/ee/jdbc":sqlCommandRetryPolicyFactory}' is expected.

Now My question is how to use reconnection strategy for Mule JDBC so that I can handle whenever database sever is down .... Please Help

Answer 1

Try putting the recconect as the first element:

 <jdbc-ee:connector name="Database_Global" dataSource-ref="DB_Source" validateConnections="true" queryTimeout="-1" pollingFrequency="0" doc:name="Database">
        <reconnect frequency="2000" blocking="false" count="5"/> 
        <jdbc-ee:query key="InsertQuery" value="INSERT INTO getData(ID,NAME,AGE,DESIGNATION)VALUES(?,?,?,?)"/>
        <jdbc-ee:query key="RetriveQuery" value="Select * from getData where ID=?"/>
 </jdbc-ee:connector>
