Hi Everyone

This week’s meeting is going to discuss a very important topic - PostgreSQL versions. The community meetings haven’t been very well attended the past month or two, so I am asking you to make a special effort to make sure you forward this on to your relevant team members.

The minimum PostgreSQL version to run DHIS2 has been 9.6 for the past I don’t know how many years. It is beyond time to move to a newer minimum version. So this week we will discuss along the lines of:

(i) features of different PostgreSQL versions
(ii) the minimum version and the recommended version
(ii) try and gather some feedback from you all on what versions are currently out there

Besides some views of Bob and me, we will also be joined by some devs from the backend team to get their perspective. And of course we want to get yours too!

Please do your best to contribute. See you Thursday 12h30 GMT.

Hi @tkipkurgat,
Thank you for sharing this with me. I was not able to join today but I have included my email in the google doc. Looking forward to joining next week and being a part of the meetings.

Dear Everyone,

I hope this message finds you well. I wanted to bring up a topic that we discussed during our server academy in Rwanda last year. We conducted a little survey on server hosting and discovered that the majority of deployments are being done in-country data centres.

This week, we are going to have a general discussion on architecting a data centre. What are some of the key considerations we should keep in mind? Topics such as networking, storage, and security amongst others are crucial aspects of this discussion.

Please join us as we delve into these important questions together.

Looking forward to our conversation.

Dear All,
I hope this message finds you in good health. Tomorrow, we will continue our discussion on PostgreSQL, building upon last week’s topic. As a reminder, we explored methods to potentially eliminate the need for analytics WAL logs, enabling practical logical replication, among other things. Bob will delve further into Incremental backups during the session.
Looking forward to our discussion.

See you there.

Hello Everyone,

I’m excited to announce that tomorrow, we’ll have the privilege of hearing from Amjad, who will be guiding us through their infrastructure and application monitoring setup. They have implemented open-source monitoring tools such as Zabbix and Glowroot for APM. Of particular interest is their approach to setting up Glowroot in a centralized manner, providing a comprehensive monitoring solution for all our DHIS2 instances. This promises to be an insightful session, and I encourage everyone to attend.

See you there.

Hello Everyone,

I hope this message finds you well. In our previous discussions, we’ve had valuable conversations regarding PostgreSQL High Availability, covering topics such as physical and logical replication.
This week, we aim to delve into strategies for enhancing the resilience of our proxy system, mitigating the risk of single points of failure. How can we transform our proxy into a highly available and fault-tolerant gateway to our infrastructure?

Please join us tomorrow as we explore this topic further. Your insights and contributions will be greatly appreciated.

Hello Everyone,

Heads Up for Dhis2 2.41 Installation:

If you attempted to set up version 2.41 with the server tools, you likely encountered an issue where it wasn’t functioning correctly. Specifically, there’s been a problem with Tomcat 9 unable to locate Java 17. This discrepancy has presented challenges since version 2.41 requires Java 17.

Looking Ahead: Ubuntu 24.04 Compatibility

In addition to addressing the Java 17 issue, I’ll also be discussing potential considerations for Dhis2 on the upcoming Ubuntu 24.04 release.

See you all tomorrow for this informative session!
