In this example I will demonstrate you how 'adctrl' utility is used for checking the status of workers or restarting workers while applying patches.

1. Open a new terminal window and setup environment to run scripts on Application Tier (for more info see How to setup environment for Application Tier at linux terminal?)

2. Start the adctrl utility

cd $AD_TOP/bin

adctrl

If you don't know what is the directory for $AD_TOP then use the following:

cd /u01/apps/[hostname]/apps/apps_st/appl/ad/12.0.0/bin

adctrl

It will ask you to provide couple of details such as APPS user DB password, APPL_TOP directory etc.

3. Once you give above information, adctrl utility will start and following menu will appear:

AD Controller Menu
     ---------------------------------------------------

     1.    Show worker status

     2.    Tell worker to restart a failed job

     3.    Tell worker to quit

     4.    Tell manager that a worker failed its job

     5.    Tell manager that a worker acknowledges quit

     6.    Restart a worker on the current machine

     7.    Exit

4. Use option 6 and then option 2 to restart a failed job

5. Now to to the terminal screen where 'adpatch' utility was running. You will see messages that 'worker restarted'. And if you have fixed the error successfully, adctrl will resume the patch application.

 

How to see the status of a worker?

At any time you can see the status of all workers run by 'adpatch' utility. To see the status:

1. Follow the steps described above (from step 1 to 3).

2. Choose option 1. All worker statuses (with the jobs they were executing or failed) will be shown on the terminal window.
