Re: RE: RE: Logical over multiple members

["Peter Dow" <pcdow@xxxxxxxxx>]

Hi Mike,

It sounds like there's some confusion here about which member limit this
thread is discussing.  When you're doing an ADDLFM there are two limits to
consider. One is the number of logical file members in the logical file, the
other is the number of based-on physical file members in any one logical
file member.

If you look at the CHGLF command, you'll see a MAXMBRS parameter just like
on the CHGPF command.  The help text for this parameter says "*NOMAX No
maximum is specified for the number of members; the system maximum of 32,767
members per file is used."  This same limit applies to the maximum number of
members in a physical file.

If you look at the ADDLFM command, the DTAMBRS parameter specifies which
physical file members this single logical file member will be based on.  The
help text for this parameter states "Up to 32 qualified physical file names
and physical file member names can be specified.  Also, the total number of
member names cannot exceed 32.  For example,
one file can specify 32 members, two files can each have 16 members, or 32
files can each have one member specified."

The system you mention probably has 150 logical file members, and from the
sound of it, each of those logical file members is based on exactly one
physical file member, so it is well within the limits.

If you don't believe the help text, try creating a logical file over a
source physical file, e.g.

TESTLF
     A          R SRCREC                    PFILE(SOURCE)
     A            SRCSEQ
     A            SRCDAT
     A            SRCDTA
     A          K SRCDAT
     A          K SRCSEQ

CRTLF FILE(PDOWD/TESTLF) SRCFILE(PDOWS/SOURCE) DTAMBRS(*ALL)

My source file has 46 members. The above statement fails with CPF7354: More
than 32 members specified on DTAMBRS. Actually, it creates the logical file,
TESTLF, but with no members. If I attempt to ADDLFM one at a time per your
suggestion, the first one

ADDLFM FILE(PDOWD/TESTLF) MBR(ABC) DTAMBRS((PDOWS/SOURCE (TESTLF)))
Member ABC added to file TESTLF in PDOWD.

succeeds, but the second one

ADDLFM FILE(PDOWD/TESTLF) MBR(ABC) DTAMBRS((PDOWS/SOURCE (TESTCYMD)))
Member ABC already exists in file TESTLF in library PDOWD.
Member ABC not added to file TESTLF in PDOWD.

fails.
