So you just installed a new EM12c R4 environment or upgraded your existing EM environment to EM12c R4. Post upgrade you go to the Job System activity page (via Enterprise->Job->Activity menu) and view the progress details  of a job. Well nothing seems to have changed, its the same UI, the same multi-page drill down to view step output, same no. of clicks, etc. Wrong! In this two part blog post, i talk about two Job System Easter Eggs (hidden features) that most of you will find interesting. These are:

  1. New Job progress tracking UI
  2. Import/Export of job definitions

So before i go any further, let me address the issue of why are these features hidden? As we were building these features, we realized that we would not be ready to ship the desired quality of code by the set dates. Hence, instead of removing the code, it was decided to ship it in a disabled state so as not to impact customers, but still allowing a brave few to experiment with it and provide valuable feedback.

1.  New Job Progress Tracking UI

The job system UI hasn’t changed much since its introduction almost 10 years ago. It is a daunting task to update all the job system related UIs in a single release, and hence we decided to take a piecemeal approach instead. In the first installment, we have revamped the job progress tracking page.

Old Job Progress Tracking UI

The current UI, as shown above, while being very functional, is also very laborious. Multiple clicks and drill downs are required to view the step output for a particular target. Also, any click leads to complete page refresh, which leads to wastage of time and resources. The new UI tries to address all these concerns. It is a single page UI, which means no matter where you click, you never leave the page and thus never lose context of the target or step you where in. It also significantly reduces the no. of clicks required to complete the same task as in the current UI. So lets take a look at this new UI.

First, as i mentioned earlier, you need to enable this UI. To do this, you need to run the following emctl command from any of the OMS:

./emctl set property -name oracle.sysman.core.jobs.ui.useAdfExecutionUi -value true

This command will prompt for the sysman password, and then will enable the new UI.

NOTE: This command does not require a restart of the OMS. Once run, the new UI will be enabled for all user across all OMSes.

EMCTL Output

Now revisit the job progress tracking page from before. You will be directed to the new UI.

New Job Progress Tracking UI

There are in all 6 key regions on this new single page job progress tracking UI. Starting from top left, these are:

  1. Job Run Actions – These are actions that can be performed on the job run like suspend resume, retry, stop, edit, etc.
  2. Executions – This region displays all the executions in the job run. An execution, in most cases, represents a single target and hence runs independently from other executions. This region thus shows the progress and status of all executions in a single view. The best part of this region is the column titled ‘Execution Time’. The cigar chart in this column represents two things – one, the duration of the execution, and two, the difference in start times. The visual representation helps in identifying runaway executions, or just compare execution times across different targets. The Actions menu allows various options like start, stop, debug, delete, etc.
  3. Execution Summary – Clicking on an execution in the above region, paints the area on the right. This specific region shows execution summary with information like status, start & end date, execution id, command, etc
  4. Execution Steps – This region lists the steps that make up the execution.
  5. Step Output – Clicking on a step from the above region, paints this region. This shows the details of the step. This includes the step output and the ability to download it to a text file.
  6. Page Options – We imagine that learning any new UI takes time, and hence this final region provides the option to switch between the new and the classic view. Additionally, this also allows you to set the auto refresh rate for the page.

Essentially, considering that jobs have two levels – executions and steps, we have experimented with a multi-master style layout. EM has never used such a layout and hence there were concerns raised when we chose to do so.

Master 1 (region 2) -> Detail 1 (regions 3, 4, & 5)

Master 2 (region 4) -> Detail 2 (region 5)

In summary, with this new UI, we have been able to significantly reduce the no. of clicks required to track job progress and drill into details. We have also been able to show all relevant information in a single page, thus avoiding unnecessary page redirection and reloads. I would love to hear from you if this experiment has paid off and if you find this new UI useful.

In the next part of this blog i talk about the new emcli verbs to import and export job definitions across EM environments. This has been a long standing enhancement request, and we are quite excited about our efforts.
