Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.

Mount tapes during the restore

During the cold restore, ontape prompts you to mount tapes with the appropriate backup files.

When restoring from a directory, the prompt specifies the absolute path name of the directory. Before responding to the prompt, you can copy or rename the file in the directory.

You can avoid the prompt by using the ontape -d option. When using this option, ensure that storage-space archive and logical-log backup files exist in the directory, as specified by the TAPEDEV and LTAPEDEV parameters. The ontape utility scans the directories for the files and uses them for the restore. After restoring the newest applicable logical-log backup file, ontape automatically commits the restore and brings the HCL OneDB™ instance into quiescent mode.
