Interface FailoverRunnable

public interface FailoverRunnable

The FailoverRunnable interface should be implemented by any class whose instances are intended to be executed with a Cluster and should have a failover. The class must define a method with one argument called run.

Method Summary

void	run(java.sql.Connection con) This method needs to be implemented if you want to use the Cluster failover feature of the PoolManager.

Method Detail

run

public void run(java.sql.Connection con)
         throws java.sql.SQLException

This method needs to be implemented if you want to use the Cluster failover feature of the PoolManager. In this method you should not use the following methods:

• setAutoCommit(boolean)
• commit()
• rollback()

because they are being used by the method executeFailover.

This method can executed repeatedly and rolled back subsequently. At first you should reset all modified objects. For example if you have a stream for an html page then you should reset the stream first. In case of a failover the html page be written repeatedly to the stream.

Parameters:

con - the connection

Throws:

java.sql.SQLException - if a database access error occurs
