Connecting to ODA derby database

By | Database Administration & Monitoring | No Comments

ODA light (ODA X7-2S, X7-2M, X8-2S, X8-2M) come with an internal derby database to manage ODA metadata. From time to time, there is a need to check or update some information within it, as for example when facing database deletion issue. I would like to strongly advise that updating manually the ODA repository should only be done after getting Oracle support guidance and agreement to do so. Neither the author (that’s me 🙂 ) nor…

Where can you find core developers asking people what is missing in PostgreSQL? pgconf.eu.2019

By | Database Administration & Monitoring | No Comments

One of the major advantages of PostgreSQL conferences when you compare it to other conferences is, that you can listen to talks where the actual developers are presenting their work. You have questions about a feature, you want to know more about this or that: Just catch one of the developers and start to talk. It is as easy as that. Today it was even more impressive: Alvaro came to our booth and asked what…

Creating a customized PostgreSQL container using buildah

By | Database Administration & Monitoring | No Comments

Quite some time ago I blogged about how you could build your customzized PostgreSQL container by using a Dockerfile and Docker build. In the meantime Red Hat replaced Docker in OpenShift and SUSE replaced Docker as well in CaaS. As a consequence there need to be other ways of building containers and one of them is buildah. You can use buildah to build from a Docker file as well, but in this post we will…

Oracle 19c

By | Database Administration & Monitoring | No Comments

Oracle 19c has been released quite a while ago already and some customers already run it in Production. However, as it is the long term supported release, I thought I blog about some interesting information and features around 19c to encourage people to migrate to it. Download Oracle 19c: https://www.oracle.com/technetwork/database/enterprise-edition/downloads or https://edelivery.oracle.com (search e.g. for “Database Enterprise Edition”) Docker-Images: https://github.com/oracle/docker-images/tree/master/OracleDatabase Oracle provides different offerings for 19c: On-premises: – Oracle Database Standard Edition 2 (SE2) –…

SQL Server 2019 Accelerated Database Recovery – Instantaneous rollback and aggressive log truncation

By | Database Administration & Monitoring, SQL Server | No Comments

In my previous article about Accelerated Database Recovery (ADR), I wrote mostly about the new Persistent Volume Store (PVS), how important it was important in the new SQL database engine recovery process and the potential impact it may have on the application workload. This time let’s talk a little bit more about ADR feature benefits we may get with instantaneous rollback and aggressive log truncation. These two capabilities will address some DBA pains especially when…

Documentum Administrator in a Container

By | Database Administration & Monitoring | No Comments

In article A Small Footprint Docker Container with Documentum command-line Tools, we presented a possible way to containerize the usual Documentum clients idql, iapi, dmawk and dmdocbroker. Those are command-line tools mostly used in batch processing or for one-of-its-kind manual tasks such as investigating or troubleshooting. OpenText also offers Documentum Administrator (aka DA), a java WDK-based client which is very useful for the occasional manual tasks. With its GUI running in a browser, it gives…

A Small Footprint Docker Container with Documentum command-line Tools

By | Database Administration & Monitoring | No Comments

The aim here is to have a minimalist container with the usual Documentum clients idql, iapi, dmawk and dmqdocbroker. Documentum Administrator (DA) could also be a useful addition to our toolbox. We will show how to containerize it in a future article. A word of warning is in order here: the title’s catchy “small footprint” qualifier is relative. Don’t forget that said container will contain a certified O/S, a JRE, the DFCs and a few…

Migrating Oracle database from windows to ODA

By | Database Administration & Monitoring | 2 Comments

Nowadays I have been working on an interesting customer project where I had to migrate windows oracle standard databases to ODA. The ODAs are X7-2M Models, running version 18.5. This version is coming with Red Hat Enterprise Linx 6.10 (Santiago). Both windows databases and target ODA databases are running PSU 11.2.0.4.190115. But this would definitively also be working for oracle 12c and oracle 18c databases. The databases are licensed with Standard Edition, so migrating through…
