Hello,
Does calling this pgm harm anything on my i?
No... not unless there's an undiscovered bug. This program was created
because older releases of IBM i (actually, OS/400 at the time) didn't
have a way to collect IFS data needed for planning system migrations,
save/restores, updates, etc.
In newer releases, it's replaced with RTVDIRINF & friends.
Does is delete anything?
Not that I'm aware of... it's purpose is only to collect information.
Does it cause locking of objects?
I suspect it puts shared locks on the directory objects while it's
reading them, but I don't know for certain.
Will calling the pgm only produce a report of the IFS?
It reports on a subtree of the IFS, specified in the 2nd parameter. So,
if you call it like this:
call qsrsrv parm("METRICS" '/home')
It'll only report on the /home directory, or anything within it (any
directories, subdirectories, etc inside /home)
If you specify '/' in the 2nd parameter, it'll analyze all areas of disk
that are available to the IFS interface.
I heard that you can specify "EPFS" in the 3nd parameter if you want to
restrict the search to local filesystems, but I haven't tried that, myself.
call qsrsrv parm("METRICS" '/' "EPFS")
But, unless you're stuck on a really old release, I would not use QSRSRV
today, I'd use RTVDIRINF instead.
And I'd never even consider using QSRSRV from a program (except maybe a
one-off program) as it's not an API. It should only be used
interactively for administration/housekeeping/planning of your system.
