Comments on: AS/400 Program To List Physcial Files with Deleted Records

I’d suspect that first you really only want PF-DTA (data files) while ignoring PF-SRC (source) files.

Data files will tend to have only single members while source files will tend to have many members. Further, it’s a near certainty that you won’t be caring about deleted records in source files; so there’s almost no reason to include them.

It’s possible (likely?) that running DSPFD individually against only data files might make a significant difference.

However, there’s not enough info in the question to make a suggestion. Without knowing what “the set” of files is that DSPFD is run over, everything is guesswork.

Can you at least tell us what the DSPFD runs against? What files does it request?

Also, does the program merely ‘list’ the members with deleted records or does it do something with the records from the *outfile?

The APIs at Work Second Edition book (note that I'm the author so this is somewhat a vendor response) contains several sample programs that find the files/members with deleted records exceeding a user specified percentage of records and optionally reorganizes the members.

I think the API’s you want to take a look at are QUSLOBJ (to get the list of PF into a user space) , QUSLMBR(to get a list of members) and QUSMBRD (to get the info about the member). I found that going with API’s is way faster than using the CL commands with output to a file. Using these APIs you can build your own file with files having deleted records.

If your goal is to run RGZPFM you’re going to need the member name anyway.
