Members show up in IBM catalog view QSYS2.SYSPARTITIONSTAT.  You could get a list of them including creation and last-use date with this:

select table_schema,table_name,table_partition,
       creation_timestamp, last_used_timestamp
  from qsys2.syspartitionstat
 where table_schema = 'EMAILLIB'
   and table_name = 'LOTTAEMAIL';

At one of my customers, there is an email application for the IBM i that uses a separate member for each email. Currently has 27,581 members.

There is also an application file that has 32,386 members. I tried WRKMBRPDM on it and got PDM0371:

Interesting...

I didn't know there was such a difference in the number of members vs
partitions...
Nor can I think of any time where I've seen 1000's of members used.

How are you using those 1000's of members?

A partitioned table is not an exact replacement for a multiple-member PF.
Among
other things, the system limit is 256 partitions for a table, while a
multiple-member PF can have 32,767 members.  We have several legacy PFs
that
have thousands of members.  At a prior job, we had a PF that occasionally
bumped
into the system limit, and I had to develop a process to archive and
delete some
of the members.

In addition, in some environments, multiple members are used for logical
groupings of records that are not apparent in the data, so you don't have
a
natural partitioning key column(s) available.

CREATE TABLE ...
PARTITION BY ...

The underlying system object is basically the same, a multi-member *FILE
object.
However, a partitioned table is much nicer
   - the DB manages adding members as needed, assuming you partition on a
date for instance
   - SQL statements operate against the table, you don't need to worry
about
the partitions.
   - The query engine will only look at the partitions it needs too.

Unfortunately, in order to create such a partitioned table, you need the
Db2 Multisystem product installed.
Prior to v7.5, this was a chargeable option that cost big bucks.

With 7.5, IBM now includes it as a no-charge option.
I wonder, for those of us on 7.4 or 7.3, can we ask IBM nicely for a
license key.

I work mostly with Island Pacific customers and the Island Pacific

and consequently a lot of the custom stuff that is written around it is
extremely multi-member dependent.

Is there any way to get multiple members in an SQL defined table (or any
plans to provide that functionality)?  If not, we are stuck with DDS.

Regardless of which engine is being used and what language you are
programming in, you should be using SQL to define all new tables.

Hello all, can someone confirm what I've been told: "DDS defined
tables default to the old iseries SQL engine and are less efficient
using
SQL"
which in context I'm told to use native I/O RPG to code instead of
embedded SQL if I am to use DDS files.
thank you!
