Automatic refresh the alarm table in oracle bpel 10.1.3.5 on Linux

Question

Automatic refresh the alarm table in oracle bpel 10.1.3.5 on Linux
I have bpel process with wait activity ..those are getting hang during thre processing. when I
refresh the alaram table..they are processing normally.
Is there a way to refresh the alarm table automatically for every few minutes.?
I have checked the Best Practices Guide
Tuning
com.oracle.bpel.expirationAgent.threadCount = 50
and com.oracle.bpel.threadPool.threadCount = 5
Does not help. What I am after is some way for an automatic refresh to be done say every 1hr or so.
Can this be done?? If YES, how??

Hi,
I had a similar requirement a while back, since due to poor system config we also Wait timers not expiring on time. I couldn't find a method within BPEL console to do this automatically.
I'm not a Java developer, but at the time I did use google to and put together the following. I can't tell if it is working since there is nothing written in the BPEL logs to indicate the refresh. My plan was to develop a script to detect waits not expiring, and then to run the java (below).
I used the the following blog as the basis : http://oraclebpelindepth.blogspot.com/2008/09/undeploy-bpel-with-java.html
import java.util.Properties;
import com.oracle.bpel.client.IBPELDomainHandle;
import com.oracle.bpel.client.Locator;
import com.oracle.bpel.client.ServerException;
import com.oracle.bpel.client.BPELDomainStatus;
import com.oracle.bpel.client.Server;
import com.oracle.bpel.client.auth.ServerAuth;
import com.oracle.bpel.client.auth.ServerAuthFactory;
public class DoRefreshAlarmTable {
     public static void main(String[] args) throws ServerException {
          //Properties with BPEL server connection information
          Properties props = new Properties();
          props.put("orabpel.platform", "ias_10g");
          props.put("java.naming.factory.initial", "com.evermind.server.rmi.RMIInitialContextFactory");
          props.put("java.naming.provider.url", "opmn:ormi://omv2rrm2:6003:oc4j_soa/orabpel");
          props.put("java.naming.security.principal", "oc4jadmin");
          props.put("java.naming.security.credentials", "pass4bpel");
          props.put("dedicated.connection","true");
          //Get a locator in default domain
          Locator locator = new Locator("default","welcome1",props);
          //Get a handle to the domain
          IBPELDomainHandle iBPELDomainHandle = locator.lookupDomain();
          //Refresh the alarm table
          iBPELDomainHandle.refreshAlarmTable();
