Deleting the 3 Longest-Running Jobs

The sample code below illustrates how to delete the three longest-running jobs, if the duration is longer than one minute. It is a good demonstration of how the various features of the API can be combined into single functionality as a part of any customization.

// create a WebObjectsFactory instance

WebObjectsFactory factory = WebObjectsFactory.getInstance();

// Get the job source object

JobSource source = (JobSource) factory.getMonitorSource(EnumWebMonitorType.WebMonitorTypeJob);

// Add a sort criterion that we will sort the duration of the job in descending order

MonitorSort msort = source.getSortCriteria();

msort.add(EnumDSSXMLJobInfo.DssXmlJobInfoDuration, EnumDSSXMLOrder.DssXmlDescending);

// Add a filter condition that we only get jobs whose duration are greater than or equal to 60 seconds

MonitorFilter mf = source.getFilter();

mf.add(EnumDSSXMLJobInfo.DssXmlJobInfoDuration, EnumDSSXMLMonitorFilterOperator.DssXmlGreaterOrEqual, "60");

// Set the maximum count to be 3

source.setMaxCount(3);

// Set the flag to obtain browsing information

source.setLevel(EnumDSSXMLLevelFlags.DssXmlBrowsingLevel);

try {

// Sends the request to Intelligence Server to retrieve job information,

// in this case, the top 3 loggest running jobs, each of which is over 60 seconds

JobResults results = source.getJobs();

// Check whether we have any result returned

if (results.getCount() > 0) {

// Obtain the job manipulator object

JobManipulator jobManipulator = source.getManipulator();

// Adds the job IDs to the deletion task for batch operation

for (int i=0; i < results.getCount(); i++) {

Job jobToDelete = results.get(i);

// Add a batch deletion operation

jobManipulator.addDeletionTask(jobToDelete.getJobID());

}

try {

// Submit the request to delete jobs

jobManipulator.submit();

} catch (MonitorManipulationException mme) {

// We have job deletion falure, so we display the error

MonitorManipulationFailure[] mmf = mme.getFailures();

displayFailure(mmf);

}

} catch (WebObjectsAdminException woae) {

woae.printStackTrace();

}
