About the Jobs tab

...

The Jobs tab isolates performance issues associated with currently running or completed batch jobs in your SAP system.

Performance information displayed in this tab can be used to identify and analyze the cause of a performance problem on your SAP server and is a prime source of input for future tuning decisions.

The Jobs tab shows two views:

 

...

  • Completed Job Steps. Displays performance information on batch jobs that have finished executing.

 

...

  • Running Jobs. Displays defined SAP batch jobs with one or more active batch job steps or those that are in a scheduling state waiting to become active. For active batch jobs, activity is provided while executing within a SAP batch work process. This is the only information that Precise for SAP obtains directly from SAP using a real time API, instead of the PMDB. Information in the PMDB is collected by Collectors.

For example, this tab can help you identify the batch jobs that consumed the most resources during the last day, discover what led to their high consumption and find a solution to the problem.

The Jobs tab enables you to answer the following types of questions: "Which Job’s Batch steps were executed yesterday from 8AM to 10AM?" or "For how long did job steps run yesterday and where was most of the time spent (in the Application Server or Database)?"

If the SAP Java connector is not installed on the Precise for SAP FocalPoint server, you will not be able to view running jobs in batches. The SAP Java connector can be downloaded from the SAP Web site. For more information, see the

The Jobs tab provides two different views in a table format:

 

...

  • Completed job steps

 

...

  • Running jobs

 

 

Viewing performance indicators for jobs that have completed running

The Completed Job Steps view displays performance indicators for jobs that have completed running. Clicking on the Details icon provides additional performance indicators for the selected job.

      Examining completed jobs performance

      Examining job runs over a selected time frame can help you pinpoint problematic time periods and view the general trend of job runs. In the Jobs tab you can observe how the job ran and compare the duration of a number of runs. You can sort the list of batch jobs according to duration, thereby detecting where the bottlenecks lie and investigating their causes. The duration of each job is broken down into application time, queue time and database time. This breakdown allows you to detect what is causing the performance problem.

       

       

      For detailed statistics about a specific job, click on the Details icon. This information can help you detect where your performance problem is. For example, you may discover that bottlenecks are caused by many updates in the database.

      Integration with Precise for SQL Server allows you to drill down further on a specific performance problem, helping to detect the root cause of the problem.

      Examining currently running jobs can help you identify problematic jobs that cause your system to respond poorly. You can detect jobs that are waiting to be executed, or are executing for too long a period and affecting your system’s system's performance.
