column.

My situation is as follows. I have several big SQL queries in a data
warehouse using 1 big fact tables and 10 dimension tables. The queries
join all of them together but the optimizer doesn't care which
dimension table it joins first (we ran runstats on all of them but the
dimensions look a lot alike... about same order of rows, ...). I know
it should first join on 1 specific dimension if it's in the query
since that dimension will discard...

Hi-
Something was just pointed out to me this morning. According to the
V8 Command Reference, the RUNSTATS command no longer uses the SHRLEVEL
CHANGE/REFERENCE clauses, and it looks to be replaced with ALLOW
READ/WRITE ACCESS. Is SHRLEVEL still a valid clause and
interchangable with ALLOW..., or has it been deprecated and is it, or
will it eventually become, invalid? We currently are not seeing any
errors using SHRLEVEL in our...

Hi.
I am trying to test out the automatic maintanance with notification
feature of DB2 v8.2. I have enabled the auto maint with notification.
The problem I am facing is that I only get email notifications from DB2
when there is an alarm as follows:
ADM10500E Health indicator "Monitor Heap Utilization"
("db2.mon_heap_util") breached the "upper" alarm threshold of "95 %"
with value "124 %" on "instance" "DB2"....

Hello,
What kind of difference does it make to update statistics
via 'REORGCHK UPDATE STATISTICS ON TABLE ALL' or by running
directly 'runstats on table xxx.yyy with distribution and detailed
indexes all" for all tables ?

I designed a datagrid with editable server controls such as text boxes,
dropdowns in each row. That way, the user does not have to click "Edit" to
get the editable controls.
And with one save button, I loop through each item, FindControl on each
field, and save all the records displayed by the datagrid on one swoop.
The problem is, it takes a looong time to draw the server control initially
since all rows have to be populated with...

I've got a large table on db2 8.2.1 that I rarely perform runstats on.
It has about 600 million rows organized in a single MDC time dimension
on a non-dpf warehouse.
Anyhow, we recently ran runstats on it with a 20% sampling. After this
was performed the highly selective queries using the time dimension
slowed down drastically (8000% increase in duration). Earlier today I
marked the table 'volatile' and queries went back to normal. ...

Hi, I have just taken over as the DBA for a database that has not had any reorgs/runstats run against it for the last three years. As a first step, I have just run reorg/runstats against the system catalog tables & rebound packages.
I next intend to reorg/runstats all the application tables that I have identified as needing this and due to the remote possibility of this causing an adverse affect on performance, it has been decided that I...

If RUNSTATS is called directly, we can specify UTIL_IMPACT_PRIORITY to
limit CPU consumption. For automatic runstats, there is no place to
specify this paramater. Will it use the DBM value of UTIL_IMPACT_LIM?
Thanks in advance,
Norm

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
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,...
