ONBAR

Hi All, Can you tell me please how to start backup using Onbar? Before I run the command "onbar -b", I suppose to set up onconfig and ISM. Is it right? I did it based on the Informix Backup and Recovery Book, but in several parts it doesn't explain clearly, like they ask to start onbar worker process to verify the ISM. Or any online reference quick start guide using onbar with samples? Thank you very much. -- Best Regards, Chelsia
