I'm confused about something I did this week. I have an 8.1.7.4 database with tables partitioned by dates. I recently dropped my maxvalue tablespace, added a few more partitions for up-coming dates, then put the maxval partition back on. (I save the data that was in the maxval partition first and put it back in when I was done.
These tables also contains BLOBS.
All of my indexes were at a status of either "Valid" or "Usable" in the case of...

I've been doing some experiments with speeding up copying tables of
approximately 1 million rows between databases using BCP and BULK INSERT.
I noticed that the total time for removing the indexes (non-clustered) and
then recreating them after the BULK INSERT was significantly less than just
doing the BULK INSERT with the indexes left there, even though I specified
TABLOCK.
I would have expected SQL Server not to update the index until...

So yea... I rm-ed a rlv that our TS_FACT2 tblspace was using. So our
db went to the crapper. The tblspace didn't have any pertinent info,
so I'm ok with dropping the tblspace and starting over.
These are the commands and errors that I have found:
--db2 => restart database sware drop pending tablespace (TS_FACT2)
DB20000I The RESTART DATABASE command completed successfully.
--db2 => list tablespaces

Hi,
I need some clearance on the following questions:
1) Does LOAD command updates indexes defined for a table?
2) Is REPLACE option in the LOAD command a logged operation?
Help will be greatly appreciated.
TIA

hi,
our db2advis is broken and i am trying to find other ways to get
recommended indexes
i tried using command "SET CURRENT EXPLAIN MODE RECOMMEND INDEXES" and
it populated ADVISE_INDEXES table. new indexes recommended by this
command does not have runstats on it.
how can i evaluate new suggested indexes ?
do i have to physically create these indexes and then explain my SQL ?
can i do it without actually creating suggested indexes ?

Hello,
I always assumed that dropping table will drop everything associated
with it like indexes, references etc.
I just noticed that after dropping table A and recreating it and then
creating index on it gave me error
DROP TABLE tmp
DB21034E The command was processed as an SQL statement because it was
not a
valid Command Line Processor command. During SQL processing it

As some readers of this newgroup can recall, I use Cognos' program
called Data Manager to build my data warehouse. I has the ability to
create indexes, however I cannot add other arguments to its command.
It has a basic command such as
CREATE INDEX PERSONNEL_ID ON
"dbo"."F_Personnel_Detail" ( "PERSONNEL_ID" )
The index by default is built in the PRIMARY filegroup.
I am testing out putting the indexes in their own filegroups and

Hello all!
I created a range-partitioned table, and noticed that indexes were created
as "NOT PARTITIONED" (through db2look), even though I ran the index creating
commands without this parameter.
Not that I care too much now about it :-)
But what will happen when once upon a time in the future I execute the
"attach partition" command, and so add another partition to the existing
(partitioned) table.
Will the indexes then be automatically...

Hi all,
I am comming along with all this Linus/DB2/scripting business...I am no
longer scared of it!! (LOL). But,
I need to create a .ksh script that does a REORGCHK and output only tables

My goal is to reorgchk and run reorgs based on entries in this reorg file as
shown in the example below.
I have tried my hand at the following failing script and hope that gurus here
can throw me a lifeline of examples on how to...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
