Could someone confirm which tablespace is being used when running ALTER &
CREATE INDEX.
Is it the tempspace or the tablespace where the table resides?
Many thanks,

just got out of a "class" on EXPLAIN, from a 390/v6 maven. was told
that ACCESSTYPE = 'R' in the plan_table meant a TableSpace scan.
hmmmm. next step up (or down, depending on your outlook) wasn't a
Table Scan.
thought this might be a MainFrame thing; but a look at DB2Info on my
UDB 7.2 server showed the same thing.
this is truly puzzling. is there an explanation of EXPLAIN which
describes how to get a Table Scan???? or are we...

Hello,
Every so often, I'm asked to help people recover data from tables that
were either dropped or where to much data was DELETEed.
The complications related to restoring data are a problem. The SAS users
are laughing because they can (to a certain extend) easily go back to an
earlier SAS table by simply starting dsm. Of course, a flat file table is
different than a relational table; but still, the trouble related to
restoring DB2...

Hi,
Using DB2 version 9, fixpak 2 on AIX 5L.
I created my DDL for defining a Primary Key to be done by a ALTER TABLE command, but I could not find a way of naming the tablespace to control were the index that gets created goes.
I did find that I could create the table with the clause "INDEX IN ...", name the tablespace I wanted and then when the ALTER TABLE ran it resulted in the index going into the tablespace I wanted. I guess I could...

Hi,
We're running DB2 v8.1 on a windows platform and have a database that
is quite large. It basically contains one table with a BLOB field
(each blob is a zip file, maybe 500K to 1MB), and this particular
table is close to 300GB in size. We are not experiencing any
problems, and there is plenty of space on the server, but I was just
wondering if there is limit in DB2 to how big this table can get.
We are guessing it is going to...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
