Documentum – xPlore online rebuild stopped because of “immense term”

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

In relation to my previous blog about custom facets not showing up after full reindex, a customer was doing a migration that just completed. After the full reindex, there were no facets because of what I explained in the blog. Knowing that the online rebuild is normally faster than a full reindex, I helped to start this operation but after a little bit more than a day of processing, it failed on a document. The…

Documentum – Custom facets not showing up after full reindex?

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

Beginning of the year, while performing a migration from a Documentum 7.3 environment on VM to Documentum 16.4 on Kubernetes, a customer had an issue where their custom facets weren’t showing up on D2 after a full reindex. At the end of the migration, since xPlore has been upgraded as well (from xPlore 1.5 to 16.4, from VM to K8s), then a full reindex has been executed so that all the documents are indexed. In…

Solr Sharding – Shard creation

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

I wrote this blog in conjunction with the one about the Solr Sharding – Concepts & Methods a year ago and it was 95% completed but then I had other stuff to do and just forgot I didn’t publish it. It might be a little bit late but well, better late than never… It will complete the overview I wanted to share around the Alfresco Clustering and in particular around the Solr Sharding. In this…

Documentum – Some things to take care of when migrating/upgrading

By | Application integration & Middleware, Enterprise content management | 2 Comments

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….

Documentum – DARs installation fails Java 11

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

As you probably heard if you weren’t in an underground bunker for the past 2 years, Oracle changed the licensing of the Oracle JDK. If you want to read more about it, there is a good FAQ here. This obviously had some important repercussions everywhere and Documentum wasn’t exempted. I would have a lot to say about the way OpenText tried to adapt since Documentum 16.4 (and kind of failed) but that’s not really the…

Documentum Upgrade – Castor is locked!

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

One of the best practices while doing upgrade of Documentum is to unlock the various repository objects before starting. This will make sure that if the upgrade process requires an update of some objects, then it will succeed and not cause you issues because you are missing some pieces. This also brings a second benefit: it means that if you ever see locked objects after the upgrade, then something probably went wrong somewhere.   In…

Documentum – Change/Rename of LDAP Config object

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

Using an LDAP Server with Documentum (or any ECM for that matter) is pretty common to avoid managing users locally. In this blog, I wanted to talk about something that isn’t very common and that is the change of an LDAP Server. I’m not talking about just changing the server where your LDAP is hosted but rather changing the full LDAP Server Config inside Documentum (including its name). This is probably something that you will…

Documentum Upgrade – Missing DARs after upgrade

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

As part of the same migration & upgrade project I talked about in previous blogs already (corrupt lockbox, duplicate objects & wrong target_server), I have seen a very annoying and, this time, absolutely not consistent behavior in some upgrade from Documentum 7.x to 16.x versions. The issue or rather the issues I had was that random DAR files were not installed properly. This makes it rather difficult to anticipate since you basically don’t know what…

Documentum – D2-REST Privileged Client utility 16.7+ fails with class not found

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

In previous blogs, I already talked about how to fix issues with the D2 Privileged Client utility (for 16.4.0, 16.5.0 and 16.5.1) as well as how to execute/use this utility for automatic/silent registration & approval of DFC Client IDs. I’m now back to this topic because I had the opportunity recently to work with D2-REST 16.7.1 so I took some time to compare the 16.7.0, 16.7.1 and the newly released 20.2 versions as well of…

Documentum Upgrade – Switch from Lockbox to AEK key

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

As you probably know already, Documentum removed the support for RSA Libraries and RSA Lockbox starting with Documentum version 16.7. This means that if you are planning to upgrade to 16.7 or higher versions, you will first need to remove the lockbox from your installation and extract your AEK key from it before starting the upgrade process. To be completely exact, upgrading to 16.7 or above in place (using VMs for example) is normally going…
