Bringing up an OpenShift playground in AWS

By | Application integration & Middleware, Database Administration & Monitoring | No Comments

Before we begin: This is in no way production ready, as the title states. In a production setup you would put the internal registry on a persistent storage, you would probably have more than one master node and you would probably have more than on compute node. Security is not covered at all here. This post is intended to quickly bring up something you can play with, that’s it. In future posts will explore more…

Keine Angst vor Container Technologie (DOAG 2018)

By | Docker | No Comments

Seit 30 Jahren bin ich in der IT-Branche tätig, hatte immer wieder mit Oracle mit RDBMS Systemen zu tun. Nun, seit bald 4 Jahren als Berater bei dbi services habe ich sehr viel Berührung mit Oracle Datenbaken, daher auch mein Besuch der DOAG 2018. Mit grossem Interesse reiste ich zur DOAG nach Nürnberg und hatte mir vorgenommen zum Thema OpenShift und Container, diverse Sessions zu besuchen. Warum OpenShift? Nun seit einiger Zeit sehen wir Projekte(PoC) bei unseren…

Deploying SQL Server on MiniShift / RedHat OpenShift

By | Database Administration & Monitoring | No Comments

Currently we begin to see customer adopting containerization for SQL Server databases (mainly driven by CI/CD and DevOps trends). A lot of them are using RedHat OpenShift as container management platform. From my side, I didn’t want to setup a complete OpenShift infrastructure on my lab to test only my SQL Server pod deployment on such infrastructure. I rather installed MiniShift that comes with one OpenShift node cluster which perfectly meets my requirements.    …

Backing up and restoring EDB containers in MiniShift/OpenShift

By | Database Administration & Monitoring | 4 Comments

The last blogs in the series are already some days old: Setting up MiniShift, Deploying EDB containers in MiniShift/OpenShift, Customizing PostgreSQL parameters in EDB containers in MiniShift/OpenShift, Scaling the EDB containers in MiniShift/OpenShift, EDB Failover Manager in EDB containers in Minishift/OpenShift and EDB Failover Manager in EDB containers in Minishift/OpenShift – Failovers. What is missing is how you can backup and restore instances running in this container deployment and that is the topic of this…

OpenShift on my Windows 10 laptop with MiniShift

By | Oracle | One Comment

By Franck Pachot . If you want to play with OpenShift on your laptop, you can, in a Virtual Machine. I have VirtualBox installed on my laptop. I’ll install Minishift here, which will create the VM to run OpenShift with few simple commands only. On Linux you can refer to Daniel’s post. Here is the Windows version. Oh, and Daniel did that to run Postgres but my goal is to run an Oracle container of…

EDB Failover Manager in EDB containers in Minishift/OpenShift – Failovers

By | Database Administration & Monitoring | No Comments

In the last post we had a look at the basic configuration of EDB EFM and confirmed that we can do manual switchovers for maintenance operations. Being able to do a switchover and switchback is fine but what really is important are automatic failovers. Without an automatic failover this setup would be somehow useless as a) EDB EFM is supposed to do exactly that and b) without that we would need to implement something on…

Scaling the EDB containers in MiniShift/OpenShift

By | Database Administration & Monitoring | No Comments

When you followed the last post you should have two pgpool instances and one EDB Postgres instance running in OpenShift. pgpool is responsible for the load balancing, meaning: Send write requests to the master instance and spread read requests over all instances. In the current setup this does not make much sense as we only have one instance so in this post we will scale the setup to finally consist of one master and one…
