Oracle Autonomous Linux: cron’d ksplice and yum updates

By | Cloud, Database Administration & Monitoring, Oracle | No Comments

By Franck Pachot . Oracle Enterprise Linux (OEL) is a Linux distribution which is binary compatible with Red Hat Enterprise Linux (RHEL).

Documentum – LSS registerOracleVersionView script with wrong content

By | Application integration & Middleware, Entreprise content management | No Comments

As discussed in a previous blog, working with LSS might prove a little bit challenging from time to time. In this blog, I wanted to share an error I saw while installing LSS 16.6.1 on an Oracle database. Initially, I developed my silent installation for LSS (while encapsulate the LSS silent scripts provided by OpenText) using a PostgreSQL database because it’s usually easier to setup an environment on Kubernetes with PG because of licenses.  …

Adding a dbvisit standby database on the ODA in a non-OMF environment

By | Database Administration & Monitoring, Oracle | No Comments

On the ODA side we are working with OMF configuration. The dbvisit version available at that time was version 8. You need to…

Migrating Oracle database from windows to ODA

By | Database Administration & Monitoring, Oracle | 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.

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

When it comes to troubleshooting processes or to get a deeper look of how SQL Server works internally , I always used debugging tools as windbg on Windows and since SQL Server is available on Linux, I switched to strace tool. But let’s add containers in the game now. I didn’t want to touch any based image for applications including SQL Server with debugging tools added. So, my concern was to figure out how to…
