A value of “0″ is equivalent to the the data
area not existing and user isolation is disabled

A value of “1″ will enable user isolation for FTP users
with a home directory in the ROOT file system; FTP users with
a home directory in QSYS, QDLS, QOpenSys, QLANSRV, or QOPT
file systems will not have user isolation and the behavior
will be as if user isolation was disabled. FTP users with a
home directory in the supported ROOT file system where that
directory does not exist will not be allowed to user FTP.

A value of “2″ will enable user isolation for FTP users
with a home directory in the ROOT file system; FTP users
with a home directory in QSYS, QDLS, QOpenSys, QLANSRV,
or QOPT file systems and users whose home directory
does not exist will not be allowed to use FTP.

What current library do you want?

FTPUSR is currently set up this way:

Current library  . . . . . . . .   *CRTDFT

The definition of *CRTDFT is partially given in the <help text> for that attribute. Most system functions will use QGPL when no current library is assigned. QGPL is the system “General Purpose Library”. It’s used when nothing else fits.

If you can’t think of anything better, then create a library named FTPUSR and set it as the current library.

However, all of that is about just “current library”. A library list has a number of additional possible libraries. If you don’t want additional libraries in the user portion of the library list, then change the initial library list on the FTPUSR job description to *NONE.

Exactly what do you need to accomplish? What business purpose are you working on?
