Re: Failure to permanently apply ptf's prior to an upgrade

Sounds like I can just delete them then.


I think so--and I probably would.
In your explanation you said the save files contained stream file fixes. But it didn't say how it used the save file contents. It did talk a bit 
about renaming this and that though.
The contents of the QxxnnnnnJn save files are stream files. I haven't bothered to determine the exact steps but it is much the same as the processing for traditional OS/400 objects. I might do that the next time I build a stream file PTF.
The basic process is the new stream file is restored as QPZxxxxxxxx, the current stream file is renamed to Qpzxxxxxxxxx, the replacement stream file is renamed to the proper name. Removing the PTF reverses the process.
If you display the contents of the QxxnnnnnJn save files you can see the file names and directory path. If you then do a WRKLNK on that path you should find a number of QPZxxxxxxx stream files (presuming you are authorised to see them). These are either PTFs that are loaded but not applied, or PTFs that are applied and could be removed. 


I may even run a DSPPTF to an outfile and a DSPOBJD to an outfile.  And
any item in the DSPOBJD that is a save file and begins with SI, SF, MF
(and since they're freaking old God knows what else) will have their first 7 characters compared with the DSPPTF. First time will be a report. Then 
option will be added to blast them.
As far as I know public PTFs have been SF and MF since OS/400 VRM110. The SI ones came in with VRM510 and replaced the SF. I'm fairly sure MF PTFs haven't changed their prefix. 

Your approach seems safe enough.
