- Method Detail
  - purgeOwnedRepositoryData
```
void purgeOwnedRepositoryData(String tag)
```
    This method will purge all JobExecution, JobInstance, and job data "owned" by a given "tag". Job purge only happens, however, if there are no other JobInstance(s) "owned" by other "tag"(s). It does not guarantee a consistent view of the job repository, so this method should only be issued when no jobs are being executed "owned by" this tag. If this type of external synchronization is not used, the behavior is undefined.
    
    Parameters:
    
    tag - A "tag" (or "app name", generically speaking).
