dbi services Blog
Welcome to the dbi services Blog! This IT blog focuses on database, middleware, and OS technologies such as Oracle, Microsoft SQL Server & SharePoint, EMC Documentum, MySQL, PostgreSQL, Sybase, Unix/Linux, etc. The dbi services blog represents the view of our consultants, not necessarily that of dbi services. Feel free to comment on our blog postings.
I recently realized there are very few information about multiple ADTS instances installation and management. And we have a customer which has two ADTS running for one docbase. I therefore decided to write a couple of blog posts on "Multiple ADTS", since it is likely to be helpful for someone in the same situation.
Do you know why Oracle Database is leading the database market for more than 30 years? Do you know any other software that is still the main solution after decades? It think that it is because Oracle is a good software from the get go. Many early decisions in the software architecture have revealed later how they were the right decision. Several decisions, such as the C language that made it portable to all platforms that were relevant during those 30 years, or the parallel server that has brought RAC when standalone servers were not able to scale anymore. Here I'll illustrate a decision made 15 years ago that has made the whole 12c pluggable databases stuff possible.
Comme vous le savez peut-être déjà, le plus grand événement SQL Server francophone arrive bientôt. Les journées SQL Server 2014, organisées par le GUSS, (Groupement des Utilisateurs SQL Server) sont à Paris les 1 et 2 décembre 2014. dbi services y est aussi - et vous?
When I have to install a virtualized SQL Server FCI at a customer place as an SQL Server consultant, the virtualized environment usally is ready. I guess this is the same for most part of the database consulting people. Since we therefore lack practice, I have to admit that we do not always know the good configuration settings to apply to the virtualized layer in order to correctly run our SQL Server FCI architecture.
During a migration from D2-Config 3.0 to D2-Config 4.1, we have encountered 2 issues. In order to have a clean installation and the insurance of being able to backup the configuration, we have decided to perform a full config export on D2-Config 3.0 and a full import with a configuration reset to D2-Config 4.1.
The Documentum D2 3.1 SP1 release is kind of a mix between D2 4.1 APIs (using D2FS in backend) and D2 3.1 front-end. It needs SSO to be fully implemented and the configuration has to be applied for 3.1 as well as for D2FS. For D2FS, the same configuration applies whether you are using the NT Lan Manager (NTLM) or Kerberos authentication.
To remove an agent in the previous Oracle OEM Cloud Control 12c versions, you first had to delete its targets, stop the agent, and remove the host target. Only then were you able to remove the agent. In version 22.214.171.124, the decommission agent feature has been greatly improved.
When can we use IOT? That's a question I had when giving recently the Oracle DBA essentials workshop. the DBA Essential is very dense and there is only half a day about performance. We have the Oracle Performance Tuning workshop to go into those details. But IOTs are under used in my opinion, so I'll post a use case for them where they are a good idea.
