This parameter indicates how old any image in the group can become before the batch is submitted as a duplication job. It applies to both disk and tape.
The MAX_MINUTES_TIL_FORCE_SMALL_DUPLICATION_JOB entry working differently in this release than it did in previous releases.
A very small batch is not submitted to nbstserv until one source job in the batch has finished at least 30 minutes ago.
Note: |
The timer does not come into effect if the total size of all the images in the batch exceeds the parameter value. Or, if all of the source media that the duplication job requires is full. |
This parameter helps to ensure a balance between the following conditions:
Submitting many small duplication jobs too soon or too frequently.
On the one hand, nbstserv doesn't want to submit a small job if there's additional work available to make the job bigger and more efficient.
Waiting too long before submitting a small job.
On the other hand, nbstserv should not wait too long to submit a small job.
