Hello,
I consider partitioning a huge table. I am not sure wheather it is possioble
only in partitioned databases. I found somewhere in docs ( http://tinyurl.com/4oara ) that there are
(simple, segmented and partitioned) tablespaces.
What is segmented tablespace ?
Is it possible to span the the tables within multiple containers (but in
some ordered manner) with no db partitions ?

Hi,
If tablespace is defined with multiple container, DB2 will allocate
block in Round-Robin fashion as and when new block is need. But table
can't span multiple tablespace...
Cheers,

Oleg, define "huge" DB2 has a limit in the number of rows because the
RID is a 4 byte integer. With 32K pages this gives you up to 512 GB of data.
If you need more than that you can either use DPF or you use UNION ALL
views to do partitioning.
Cheers

Simple, segmented and partitioned tablespaces exist only in DB2 for z/OS and
OS/390.
Since you mention containers later in your post, I assume you working with
DB2 for LUW (DB2 for z/OS and OS/390 does not have containers). If that is
not correct, please clarify.

I don't know what LUW stands for (Linux, Unix, Windows ?) . Yes I work on

Hello, I estimeted that whole database could grow 0.8 - 1.2 TB per year. But
the client wants to be able obtain reports from the whole database. The only
facilitation is that there will be no updates, just inserts and reports.

the task I have is to write a script to restore a database from a

the backup can be as old as seven years. The container layout on the
machine to be restored
can be totally different from the machine which was backedup. So we are
going with redirect
