I am trying to create a copy of a join logical into another library.
By reading ahead... Apparently with the intention that the Join
Logical File (JLF) will be referring to the based-on physical files in
the _another_ library instead of still referring to the physical files
in the _original_ library.?
I have all the physicals in my work library
All good so far. All objects and their references within the same
library enables the Create Duplicate Object (CRTDUPOBJ) [and Restore
Object (RSTOBJ)] to /connect/ the Logical File (LF) to the same-named
based-on files that are located in the _another_ library.
But no mention, and this is critical... Where is the JLF in this
scenario? Per above "good so far", the JLF needs to be in the *same*
library as the based-on files.
and my library at the top of the list and none of the old libraries
on my library list
The library-list is immaterial. What is the one library name for all
existing based-on file references, the name of the target library, and
that all based-on file references [to which the new\duplicated LF will
/connect-with/] exist already in that target library, and that the LF is
in the same library as the based-on files, are what matters.
but when I finished doing the CRTDUPOBJ the join logical is pointing
at the original libraries, not the current one
Libraries? As in plural vs singular? But all the physical files
were noted to be in the _one_ "my work library".?.?
Also, are "my library" and "my work library" the same; though again,
the *LIBL is immaterial. Just trying to figure out if possibly those
are two different libraries, with each named in the LF as a based-on
file reference.
If the LF is not also in the "my work library" with the physical
files, then there will be no updates to the based-on file references;
i.e. correctly, the JLF will remain pointing to the original library for
the based-on file references. This is what "midrange" refers to in the
"2nd point" of the included doc quote:
[
http://archive.midrange.com/midrange-l/201510/msg00219.html]
which it does not with a regular logical.
Unless I recall incorrectly, or something seriously changed, the
rules are the same for the JLF as for any other LF.
I checked the archive and did see much. If this normal behavior?
A scripted [pseudo-coded] example with actual names and qualified
dependencies to allow for review is best for a reader to try to respond
definitively.
Such a script follows, showing the effects for a couple example
files, and how with a [not exceedingly] creative use of Move Object
(MOVOBJ) [and optionally Rename Object (RNMOBJ) if name conflicts are an
issue], the restriction can be overcome without having to fall back to
the DDS Source and Create Logical File (CRTLF).
