(a) Utility execution results
The results of execution of the database structure modification utility can be verified by the following methods:
- pddbls command (with -r ALL -a specification)
- Retrieving the dictionary table
- Executing the database condition analysis utility
(b) In the event a HiRDB file system area is corrupted
If the execution of the database structure modification utility is interrupted due to a power failure or the kill command, in some cases the HiRDB file system area can be damaged. If a conflict is detected by executing the pdfls command, use one of the following procedures to perform recovery:
- Use the pdfmkfs command to recreate the HiRDB file system area. For each RDAREA, execute the database structure modification utility on the HiRDB files that were stored.
- Execute the pdfbkup and pdfrstr commands to back up and restore the HiRDB file system area.
