我需要使用 JT400 获取所有作业的 CPU 利用率百分比。但是我无法一次获得作业列表，因为 loadStatistics() 仅在作业级别而不在列表中可用（更省时）。

剪下以下代码后，我可以一项一项地获得每个作业的 CPU%，但这需要很长时间：

AS400 as400 = new AS400("hostname", "username", "password");

//Reading SystemStatus like CPU usage and hdd usage
SystemStatus systemStatus = new SystemStatus(as400);
JobList list = new JobList(as400);
 list.addJobSelectionCriteria(JobList.SELECTION_PRIMARY_JOB_STATUS_ACTIVE, Boolean.TRUE);
 list.addJobSelectionCriteria(JobList.SELECTION_PRIMARY_JOB_STATUS_JOBQ, Boolean.FALSE);
 list.addJobSelectionCriteria(JobList.SELECTION_PRIMARY_JOB_STATUS_OUTQ, Boolean.FALSE);
 list.addJobAttributeToRetrieve(Job.CPU_TIME_USED);
 list.addJobAttributeToRetrieve(Job.SUBSYSTEM);
 list.addJobAttributeToRetrieve(Job.JOB_NAME);
 list.addJobAttributeToRetrieve(Job.JOB_NUMBER);
 list.addJobAttributeToRetrieve(Job.USER_NAME);
 //list.addJobAttributeToRetrieve(Job.ELAPSED_CPU_PERCENT_USED);


 Enumeration jobs = list.getJobs();

while (jobs.hasMoreElements())  {
    Job  j= (Job) jobs.nextElement();
    j.loadStatistics();
    //TimeUnit.SECONDS.sleep(10);
    System.out.println("Name " + j.getName() + " | Job NO : " + j.getNumber() + " | User : " + j.getUser() + " | CPU USED : " + j.getCPUUsed()+ " |  CPU% : " + j.getValue(Job.ELAPSED_CPU_PERCENT_USED));
    j.resetStatistics();
    }

有没有办法一次获得所有作业的 CPU% (Job.ELAPSED_CPU_PERCENT_USED)？

看看DB2 for i 系统服务的一些工作管理。

您应该能够从这些函数中提取您正在寻找的信息。

我当时使用 com.ibm.jtopenlite.components 解决了这个问题

JobInfo [] jobs = lstJobs.getJobs(connection, false);

        List<Point> pointList = new ArrayList<Point>();
        
        for (JobInfo job : jobs) {
            log.debug("getCPUPercent: " + job.getCPUPercent());
            log.debug("getCurrentUser: " + job.getCurrentUser());
            log.debug("getJobName: " + job.getJobName());
            log.debug("getJobType: " + job.getJobType());
            log.debug("getSubsystem: " + job.getSubsystem());
            log.debug("getTotalCPUUsed: " + job.getTotalCPUUsed());
            log.debug("getUserName: " + job.getUserName());
            log.debug("getCPUPercentInTenths: " + job.getCPUPercentInTenths());
                            
        }
