Create an impact policy

The Job Engine includes four default impact policies, which you cannot modify or delete. However, you can create new impact policies.

1. Run the isi job policies create command.
   The following command creates a custom policy defining a specific time frame and impact level. You can apply the custom policy to any job instance to enable the job to run at a higher impact over the weekend.

   isi job policies create MY_POLICY --impact medium 
   --begin 'Saturday 00:00' --end 'Sunday 23:59'

2. View available impact policies to see if your custom policy was created successfully. The following command displays a list of impact policies.
