Saving DASD space is a legitimate concern in typical AS/400 installations. Reclaiming wasted space by deleted records in physical files can significantly increase your available space, especially if your files are many and large; this space is reclaimed by reorganizing the database files.

OS/400 has given us the Reorganize Physical File Member (RGZPFM) command, which eliminates deleted records from a single member in a physical file. In the July issue, Midrange Computing published a utility to reorganize all members of a physical file with a single command, RGZPFMALL. To improve beyond that, we need another utility to reorganize all physical files in a library.

That is the purpose of the Reorganize All Physical Files command (RGZALLPF). This command (see 1) has two parameters: library name and member. With RGZALLPF, you can reorganize all members in all physical files in a library -- with a single command -- or just the first or last member of all files.

That is the purpose of the Reorganize All Physical Files command (RGZALLPF). This command (see Figure 1) has two parameters: library name and member. With RGZALLPF, you can reorganize all members in all physical files in a library -- with a single command -- or just the first or last member of all files.

The command processing program is shown in 2. It uses the DSPOBJD command to an outfile in order to obtain the names of all files located in the library that you selected. Because this program uses command RGZPFMALL (from the July issue), you should load it into your system before using RGZALLPF.

The command processing program is shown in Figure 2. It uses the DSPOBJD command to an outfile in order to obtain the names of all files located in the library that you selected. Because this program uses command RGZPFMALL (from the July issue), you should load it into your system before using RGZALLPF.

Using RGZALLPF is easy, although it may take a considerable amount of time, depending on the number of physical files in your libraries and the number of members in each file. Consider running RGZALLPF only in batch mode.

For example, you can easily reorganize all members in all the physical files contained in library MYLIB by executing the following command:

SBMJOB CMD(RGZALLPF LIB(MYLIB) MBR(*ALL))

Because deleted records have a tendency to accumulate, you can reclaim considerable space by running the RGZALLPF periodically. Make it part of your weekly system housekeeping jobs!
