Infrastructure at your Service
Over the years I have been working with Documentum, I participated in many migrations and/or upgrades. Just like everything else, this obviously builds up some experience but what if you are pretty new to Documentum and it is your first time working on one? Sure, there is the Documentation from OpenText, which is several dozens of pages (~140, depending on versions) of intense fun so prepare a lot of coffee, you will definitively need some….
By Franck Pachot . I originally wrote this as a comment on the following post that you may find on internet: https://www.2ndquadrant.com/en/blog/oracle-to-postgresql-reasons-to-migrate/ but my comment was not published (many links in it… I suppose it has been flagged as spam?) so I put it there. You should never take any decision on what you read on the internet without verifying. It is totally valid to consider a move to Open Source databases, but doing it…
This is the last post in this little series about migrating on Oracle instance to AWS Aurora with PostgreSQL compatibility. For the previous one you can check here, here and here. In this post we’ll look at how you can configure change data capture so that changes on the source Oracle instance are automatically replicated to the target Aurora instance. In a real life migration this is what you probably need as long down times…
If you followed the last two posts in this little series (here and here) this is the current status of this demo migration project: We have converted the Oracle SH schema and applied it to the target AWS Aurora with PostgreSQL compatibility instance. This worked quite well but a few objects (mostly PL/SQL procedures) would need manual actions. The next and final step is to replicate the data from Oracle to the Aurora instance using…
Introduction Big Oracle databases (several TB) are still tough to migrate to another version on a new server. For most of them, you’ll probably use RMAN restore or Data Guard, but datapump is always a cleaner way to migrate. With datapump, you can easily migrate to a new filesystem (ASM for example), rethink your tablespace organization, reorganize all the segments, exclude unneeded components, etc. All of these tasks in one operation. But datapump export can…
The Documentum installation owner is the operating system user that owns the server executable and other related files along with the OS process when the server is running. It is originally determined when the server is installed, in fact, it is the logged-in user that performed the Documentum installation.
Introduction For years, Oracle used the same mechanism for database versioning. A major version, represented by the first number. And then a release number, 1 for the very first edition, and a mature and reliable release 2 for production databases. Both of them having patchsets (the last number) and regular patchset updates (the date optionally displayed at the end) to remove bugs and to increase security. Jumping from release 1 to release 2 required a…
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…
As a SQL Server DBA we have the habit to migrate databases from an instance to another one or to a new environment. But migrate a database from on-premise to the Azure Cloud is an operation that we don’t deal with every day. As a reminder, Azure SQL Database is a relational database-as-a-service (DBaaS) which gives the ability to manage your databases directly from the Cloud with the performance of your choose, reliability, security and…
In this blog I will change the Host Name, it comes after three blogs to change the Docbase ID, Docbase Name, and Server Config Name, hope that you already read them, if not don’t delay 😉 So, let’s change the Host Name!
