RE: secondary access path owner on logical file.

["Elvis Budimlic" <ebudimlic@xxxxxxxxxxxxxxxxxxxxxxxxx>]

System can figure out if an index that has the same keys already exists and
creates the new index as a "shared access path" index.
Basically, it means that the new index is not eating up DASD, but instead
using the existing index as base.

Subject: secondary access path owner on logical file.

Hey all,

I've got  a joined logical that (I think) was duplicated from another
library.

they both have 3 files joined,

the original ( WRKLIBA/JOINLF ) file description shows it's based on these
files:
WRKLIBA/FILE2
WRKLIBA/FILE2
MSTLIB/FILE3

the new one's ( WRKLIBB/JOINLF ) file description shows it's based on these
files:
WRKLIBB/FILE1
WRKLIBB/FILE2
MSTLIB/FILE3

(note, they both use MSTLIB/FILE3)

but I noticed something weird - on the second LF (in WRKLIBB) has this
under the third based on file:

Based on file . . . . . . . . . . . . . . :            FILE3
  Library . . . . . . . . . . . . . . . . :            MSTLIB
  Member  . . . . . . . . . . . . . . . . :            FILE3
Join secondary access path owner
  File  . . . . . . . . . . . . . . . . :            WRKLIBA/JOINLF
  Member  . . . . . . . . . . . . . . . :            JOINLF

can anyone explain what this means?   Is it only using the FILE3 portion of
the access path of the WRKLIBA joined file?

Thanks,

Rick
