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...

Does anyone know what entity (utility?) checks if statistics
collections are required, if the Automatic RUNSTATS is enabled, in
version 8.2?
How often are these checks done?
Thanks.

Hi,
It's no problem to define the automatic maintenance using the wizard
but I want to use commands to automate automation. I captured the SQL
statements when activating the maintenance but that didn't help.
I couldn't find anything about it in the docs so if anybody could
help with this it would be great.
Kind regards, Gert

Hello,
we are using db2 udb v8.2 on windows.
if we need to run a reorg and runstats monthly, i think the best way
to do them is via the tool "Configure Automatic Maintainance". I find
out that for reorg, it has to be done offline. So I should schedule the
offline timing for reorg and online timing for runstats. Will the tool
automatically makes the database offline? What is the best time for the
process happen? Should i put them to...

Hi:
I'm testing DB2's new automated maintenance feature and, so far it
seems to accomplish what it is instructed to do, but we (DBA's) have no
control on when the evaluation cycle is going to happen nor when the
utilities are set to execute.
We only supply 'time ranges' for DB2 to operate upon. What I want is a
means to 'force' a new evaluation period (i.e. I'm creating and loading
new tables and I want to force a new evaluation cycle...

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. ...

Hello,
Linux RedHat AS4 running DB2 V8 FP11.
I have followed the docs at http://tinyurl.com/qckrn and enabled
automatic statistics collection. It has been 2 days since I updated my
DB cfg and I don´t see any activity regarding auto runstats.
Also, the field STATS_TIME from syscat.tables shows that all my table
statistics were last collected in March. What am I missing here ? Is

I have a stored procedure which is called by db2 "call ....."
statement from ksh script. When running from AIX DB2 v. 9.1.3 environment,
after
a while the stored procedure starts to hang and snapshot says it is on

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,

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

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...
