Re: Disk Space Reports

Good idea Susan.
A little extension to it though,
SELECT SYSTEM_TABLE_SCHEMA, SYSTEM_TABLE_NAME, SYSTEM_TABLE_MEMBER,
NUMBER_DELETED_ROWS, DATA_SIZE,
NUMBER_DELETED_ROWS * DATA_SIZE as DeletedSpace
FROM syspartitionstat
where number_deleted_rows>0
order by 6 desc

This will tell you the partition (or member) to reorganize.

If you're really bold you can build a UDF to call RGZPFM and automatically
execute the reorg. We have a UDF called QCMD we use for such things. A
DB purist might suggest, since you're reorganizing the file anyway, it
might be a good time to sort it and either add KEYFILE(*FILE) or your
favorite logical to that also. Then, if you think about it, it starts
getting complicated. Like, what if the *FILE has no key? Or how to
select the idea index or logical file?

There's the homework assignment of the day: Is there a table of database
statistics which shows you the most popular index used against a table?
Could this be used by a program to feed RGZPFM?
