pddbfrz -r LOB001
 

Explanation

The HiRDB file with full data pages (file02) is placed in frozen update status. Refer to the KFPH27024-I message or use the database condition analysis utility (pddbst command) to confirm the HiRDB files that have been placed in frozen update status.

Back up the user LOB RDAREA (LOB001) using some method other than the database copy utility (pdcopy command). Make the backup in units of the HiRDB files comprising the user LOB RDAREA (LOB001).

Explanation

All the HiRDB files are backed up (file01, file 02, and file 03).

For details about making a backup using methods other than the database copy utility (pdcopy command), see 6.7 Backup acquisition using backup-hold (backup without using the pdcopy command).

Make backups on a regular schedule, such as once a week.

Explanation

Only the HiRDB files in permit update status are backed up (file01 and file 03). You do not need to back up the HiRDB file in frozen update status (file02).

For details about expanding the user LOB RDAREA (LOB001), see 15.3 Increasing the size of an RDAREA (RDAREA expansion).

Explanation

A HiRDB file (file04) is added and the user LOB RDAREA (LOB001) is expanded.

After expanding the user LOB RDAREA (LOB001), back it up. Always make a backup, even if the number of segments used in a file is 0; for the reason, see 6.8.7 Notes.

Explanation

HiRDB files in permit update status (file01, file03, and file04) are backed up. Backing up the HiRDB file in frozen update status (file02) is not necessary.

When LOB data is added, additional HiRDB files with full data pages might be issued. Use the database condition analysis utility (pddbst command) to check for files with full data pages. For details about checking for files with full data pages, see 6.8.4 Checking for files with full data pages.

 
pddbst -r LOB001
 

If more files with full data pages have been issued, as determined in step (6), execute the frozen update command.

 
pddbfrz -r LOB001
