 Job Gantt Chart

 

The Gantt chart provides a convenient graphical overview of scheduling information for selected jobs over a period of time. It allows you to analyze the workload caused by background jobs, so you can avoid bottlenecks and optimize system resources when scheduling jobs.

Starting the Application

In the Job Management work center, under Common Tasks, choose Analyze Jobs (Gantt).

Setting the Time Zone

At the top of the application screen, you have the option to select a time zone. This setting determines whether any time period that you enter as part of your search criteria should refer to a specific time zone, or simply the time zone of the selected target system. The time zone setting also determines how the current time is labeled on the Gantt graph.

  • If you select a time zone, any time period you enter for the search refers to the selected time zone. When you execute the search, the application converts your time period entries to the target system time zone when searching for jobs on the target system.

  • If you choose to ignore the time zone, any time period you enter for the job search refers to the time zone of the target system.

Searching for Jobs

In order to display a Gantt chart, you have search for jobs to display. You can perform a standard search or a solution search:

  • Standard search

    Find jobs in one or more managed systems based on standard criteria such as the job name, user, or time period.

    Search Criteria

    Description

    Target system information

    Choose one or more managed systems to search.

    Job

    Limit the search to jobs with a certain name, or a naming pattern using wildcards (*).

    Limit the search to jobs run by a specific user.

    Job-steps

    Limit the search to a certain program or variant.

    Job-options

    Limit the search to jobs of a certain minimum duration or status. The search always returns jobs with the status Released.

    Note that the lowest possible minimum duration is 5 minutes, which means that you cannot display jobs with a runtime of less than 5 minutes in the Gantt chart.

    Job-start conditions

    Limit the search to jobs scheduled within a certain time period, or within a certain number of hours in the past or future.

    Note that the time zone setting at the top of the application window applies to the time period specified here.

    Time scale level

    Choose the layout of the Gantt chart. Note that you can change the time scale after executing a search.

  • Solution search

    Find jobs that have been assigned (via job documentation) to a specific solution and scenario, business process, or step.

    If you only specify a solution, it will be searched hierarchically to see if there is any job documentation linked with it. If there is, then the name of the job documentation will be used as the job name for the search on the target systems. The target systems are determined by the logical components assigned to the specified solution. The time zone and other search fields work the same way as the standard search.

Note Note

You can save the current job selection criteria by choosing Save Current Criteria and entering a name for your search.

To select a previously saved search, choose Select Criteria. Here you can also specify a search to be the default when the application starts.

End of the note.
Viewing the Chart

If the search returns jobs, a Gantt graph is displayed.

On the left, the jobs that meet your search criteria are displayed in a table list, grouped by server and work process. You can expand and collapse the nodes representing the servers and work processes.

The time scale is displayed above the graph.

The current time is indicated by a vertical line that divides the main graph display into two zones: On the left are past jobs which have been scheduled and run. On the right are future jobs that are scheduled but have not run yet.

Each job is represented by a horizontal bar on the graph. The position and length of the bar reflects the start time, end time, and duration of the job. You can hover over a bar with your mouse to display the job details. The color of the bar indicates the job status:

  • Red: canceled

  • Yellow: active / running

  • Blue: released

  • Green: finished

Past jobs may be marked with a black triangle, which indicates that the job ran with a delay.

Navigating the Chart

The tool bar above the chart provides some options for the display. You can do the following:

  • Hide the search area to make more room for the chart display

  • Define the chart height in pixels (default = 700 px)

  • Display a navigation window to move to a difference section of the chart

  • Display the jobs in a sortable, filterable list
