Hi,
I'm working with a customer that is trying to find a solution to
provide geographical redundancy. Our application is currently using
IBM DB2 v8.2. I have a couple of questions with regards to HADR:
1. DB2 HADR (Can it be used to support geographical redundancy in a
nested fashion (ie. Synchronous HADR at a site, and ASYNCRONOUS
between sites using the same instances/databases). If so how would we
set it up?

DB2 V8.2 FP10 on Windows
I tested the following HADR scenario:
- a new tablespace on a new filesytem is created on the primary System
- the replay on standby fails because of lacking permissions
- the tablespace is backed up on the primary system
- tables are created in the new tablespace and data is inserted (and a
couple of logs are archived)
- Takeover is done by the standby

I'm having trouble getting HADR to work with the sample databases on
two HS20 xSeries blades, Red Hat ES4 up3, DB2 8.2.4, getting the
following error.
SQL1768N Unable to start HADR. Reason code = "7" - The primary
database failed to establish a connection to its standby database
within the HADR timeout interval.
What things should I check besides the remote host and remote service
parameters on the standby database, which seem to be...

I was hoping I might be able to get an answer regarding DB2 and HADR.
Let me preface this by saying that I know very little about networking
and I'm not familiar with the HADR product or clustering. But, I've
been asked to research a couple issues for a client.
They are thinking about implementing HADR. They have DB2 production
databases running on more than one box.
Does a liscense for HADR need to be purchased for each production box...

db2 8.1 fix pack 12 on AIX 5.3
This is a newly configured HADR machine. The HADR was up and running.
I was 'playing' around some on the standby and did a db2 deactivate and
things sort of went down hill from there.
Though the Standby machine seemed to know it was a standby it would not
connect to the primary. I could not even do a db2 get snapshot to view
the hadr status on the machine. I was wanting to do a few HADR tests
before I...

I have two questions about HADR recovery. I am running db2 v8 fp12.
1) If the primary suddenly crashes would you always want to switch the
standby to the primary by force...or would there be times when you
would want to make it a standard? (and why)
2) Let us say the primary suddenly crashes (someone pulled the power
cable) and you switch the standby to primary by force. Then you bring
the primary back up and issue a START as...

Using DB2 v9.1 fixpak 2 (WSE with HADR feature) on Windows 2003 Servers
We are trying to set up HADR for two production databases. The two primary databases reside on two different servers. We would like to put the two standby databases on the same server. One of the databases (we will call it NICKNM) has tables federated from the other database (we will call it OTHER). I was able to set up HADR for these two databases so that the...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
