Number 8 in our Top 10 DB2 Support Nightmares series. This month we take a look at what happens when organisations are not able to keep up to date with the latest DB2 technology.
Imagine the scene – a broken database on an unsupported version of DB2, with no backups or log files to recover the database.
Yes – this one really was the stuff of nightmares!

The Forefront of the Development for NVDIMM on Linux KernelYasunori Goto
This is talk for Open Source Summit Japan 2020
--------------------------
NVDIMM (Non Volatile DIMM) is the most interesting device, because it has not only characteristic of memory but also storage. To support NVDIMM, Linux kernel provides three access methods for users. - Storage (Sector) mode - Filesystem DAX(=Direct Access) mode - Device DAX mode. In the above three methods, Filesystem DAX is the most expected access method, because applications can write data to the NVDIMM area directory, and it is easier to use than Device DAX mode. So, some software already uses it with official support. However, Filesystem-DAX is still "experimental status" in the upstream community due to some difficult issues . In this session, Yasunori Goto will talk to the forefront of the development of NVDIMM, and Ruan Shiyang will talk about his challenge with the latest status from CLK2019.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

2. Part 8 – Keeping Up To Date
Image of a junior DBA
It’s too large to send
Can we access the DB2 diagnostic log file
(db2diag.log) ?
It’s taking to long to open
3. Hhhhmmm, this is a common response. This is
because the DB2 diagnostic files have been append
only since time immemorial, their growth only
restricted by the maximum space available in the
file system they reside in.
The only way to curb this growth if you were using
pre-DB2 9.7 versions would be to rename the files
which would then force the creation of new ones.
Scripts had to be written to automate this process
and to delete old files after a certain period.
4. Image of a junior DBA
You have two options:
1 – The DIAGSIZE database manager parameter
2 - DB2DIAG tool with the –A or –archive option
5. DIAGSIZE database manager parameter
• From DB2 9.7 onwards
• Allows a DBA to control the maximum sizes of the DB2 diagnostic log and
• administration notification log files.
• When this parameter is set to a non-zero value, a series 10 rotating diagnostic log
files and a series of rotating administration notification log files (only on UNIX and
Linux) are used.
• Smart enough to clean up the diagnostic log directory of old log files.
• When the size of 10th file is full, the oldest file is deleted, and a new file is created.
• DIAGSIZE is the value (in MB) of the total size of all the DB2 diagnostic log and
administration notification log files on UNIX and Linux.
• 90% of the total size is allocated for the 10 diagnostic log files and 10% of the total
size is allocated for the 10 administration notification log files.
• On Windows, DIAGSIZE is the value (in MB) of the total size of all the 10 DB2
diagnostic log files on Windows.
6. DB2DIAG tool
• DB2DIAG tool with the –A or –archive option.
• This archives both single and rotating diagnostic log files.
• A timestamp, in the format YYYY-MM-DD-hh.mm.ss, is
appended to the file name.
• You can specify the name of the file and directory where it
is to be archived. If the directory is not specified, the file is
archived in the directory where the file is located and the
directory name is extracted from the file name.
• files on Windows.
7. Keeping Up To Date
It can be difficult for many organisations to keep
fully up to date with new features and indeed it is
often the case that organisations are forced to
stay on out-of-support versions of DB2.
This can be a real issue when problems arise and
they find that their DB2 systems are no longer
supported by IBM.
no longer supported by IBM.
8. The Moral
1. Where possible, try to keep up to date via fixpaks – new features are
delivered in DB2 all the time.
2. Have a Remote DBA support arrangement with an expert DB2 organisation
who will automatically keep your systems updated with the latest fixpaks.
3. Arrange regular training for DBAs, or take out a Consultancy on Demand
agreement which allows you to use consultancy hours on training, database
healthchecks or just to answer technical questions no longer supported by IBM.
9. Find out how our RemoteDBA or Consultancy on Demand services can help you to
keep your critical DB2 systems up to date.
