6.8.1 Operation subject to the frozen update command
Under the following operational conditions, the frozen update command (pddbfrz command) can be used in conjunction with backing a up user LOB RDAREA as quickly as possible:
- A method other than the database copy utility (pdcopy command) is used to back up the user LOB RDAREA.
- Backup is in units of HiRDB files.
- Updating and deletion of registered LOB data do not normally occur (the typical operation is to add LOB data).
- The user LOB RDAREA to be backed up consists of multiple HiRDB files.
