The following code removed all the bpel instances which are:
- Closed Faulted
- Stale
- Cancelled
import com.oracle.bpel.client.IActivityConstants;
import com.oracle.bpel.client.IInstanceHandle;
import com.oracle.bpel.client.Locator;
public class PurgeHelper {
public static void purgeInstances(String aDomainId, String aPassword, String aIPAddress) throws Exception {
// initialize the instance handler
IInstanceHandle instances[] = null;
try {
//check if parameters are invalid
if(aDomainId ==null || aPassword == null )//|| aIPAddress ==null)
throw new Exception(" Invalid Parameter");
// get the instances
instances = new Locator(aDomainId, aPassword).listInstances(1, -1);
// check for null
if (instances == null) {
throw new Exception("No Instances Retrieved");
}
// get the instance length
int instancesLength = instances.length;
// iterate
for (int j = 0; j <=instancesLength;++j)
// get the instance
IInstanceHandle tempInstance = instances[j];
// check for null
if (tempInstance == null)
continue;
//check the state
if(tempInstance.getState()!= IActivityConstants.STATE_CLOSED_FAULTED ||
tempInstance.getState()!= IActivityConstants.STATE_CLOSED_STALE ||
tempInstance.getState()!= IActivityConstants.STATE_CLOSED_CANCELLED)||
){
// remove the instance from the Dehydration Store
tempInstance.delete();
}
}
} catch (Exception err) {
// handle exception
}
}
/* Some usefull Bpel instance status */
// IActivityConstants.STATE_CLOSED_FAULTED);
// IActivityConstants.STATE_CLOSED_ABORTED);
// IActivityConstants.STATE_CLOSED_COMPLETED);
// IActivityConstants.STATE_CLOSED_CANCELLED);
// IActivityConstants.STATE_CLOSED_COMPENSATED);
// IActivityConstants.STATE_CLOSED_FINALIZED);
// IActivityConstants.STATE_CLOSED_PENDING_CANCEL);
// IActivityConstants.STATE_CLOSED_STALE);
}
Note. You need to add orabpel.jar for compilation.
