Hi Art,
The list is long . So I attach it for your reference.
The wi_d#dbs dbspaces are for the fragmented by selecton data.
The wi_x#dbs dbspaces are for the fragmented by selection indexes.
The sql results (part A) only show wi_d#dbs names.
The "oncheck" results (part B) show both wi_d#dbs (for data) and wi_x#dbs
(for indexes).

(See attached file: web_indext.doc)

Long N

Please respond to

ids

It should work regardless of where the index and table partitions are
stored.
They all share the same lockid so that links them to the core table's
partnum
and the partnum on each sysptnhdr row for each table or index fragment will

identify the dbspace that it resides in. Have you tried it on such a table?

What are the results?

Hi Art,
This sql works well for a fragmented table where data and index are in the
same dbspace.
However in case the fragmented indexes are allocated on different dbspaces
how can we find their dbspaces and page usages with SQL statements?
(currently I run oncheck -pT and browse all the data and indexes sections).

<SIGH> I type too fast. Final version of the second query corrected here:

select dbinfo( 'dbspace', sph.partnum ) dbspace, st2.dbsname database,

st2.tabname partition, nptotal, npused,

npdata, (npused - npdata) npindex
from systabnames st1, systabnames st2, sysptnhdr sph
where st1.partnum = sph.lockid and st2.partnum = sph.partnum
.......
order by 2, 3, 1;

In sysmaster:

select dbinfo( 'dbspace', sph.partnum ) dbspace, dbsname database, tabname,

nptotal, npused, npdata
from systabnames st, sysptnhdr sph
where st.partnum = sph.partnum
.......
order by 2, 3, 1;

If you want this for a specific database and/or table add filters on
dbsname
and tabname in place of the elipsis.

This will return only table partitions. If you want to include index
partitions also you have to include systabnames twice, once for the table
level
filter and once to link all of the table and index partitions by lockid:

select dbinfo( 'dbspace', sph.partnum ) dbspace, st2.dbsname database,

st2.tabname, nptotal, npused, npdata
from systabnames st1, systabnames st2, sysptnhdr sph
where st1.partnum = st2.lockid and st2.partnum = sph.partnum
.......
order by 2, 3, 1;

Here if you want to filter for specific database(s) and/or table(s) you
need
to
add filters on st1.dbsname and/or st2.tabname.

Hi,
I'm looking for some SQL that will accurately display the number of
pages allocated and used for a fragmented table with its indexes
(IDS9.4, AIX-4KB page size). The report should show the total number of
pages (data & index) in each dbspace.

E.g.
Table x is fragmented (by expression) across 10 dbspaces and has 5
indexes.
Dbspace 1:
Pages allocated: 100,000
Pages used: 98,000

Dbspace 2:
Pages allocated: 100,000
Pages used: 99,000
........
........

Thank you.
