Application Server

Middleware is where applications meet infrastructure. Here our consultants write about WebLogic, JBoss EAP, WildFly and Tomcat in real production environments: installing and clustering them, patching, deploying applications and finding out why something stopped working.

Documentum – IndexAgent can’t start in normal mode

Everybody familiar with Documentum knows that just starting the JBoss/WildFly hosting an IndexAgent isn’t really enough to have the indexing working: the IndexAgent must be started from the UI (or via DA or via the job or via iapi or automatically via the Repository startup or …). Starting the IA in “normal mode” is usually something that takes a few… 

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

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… 

Documentum – Custom facets not showing up after full reindex?

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),… 

Solr Sharding – Shard creation

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… 

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

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… 

Documentum – DARs installation fails Java 11

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… 

Documentum Upgrade – Castor is locked!

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… 

Documentum – Change/Rename of LDAP Config object

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… 

Documentum Upgrade – Missing DARs after upgrade

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… 

Documentum Upgrade – Switch from Lockbox to AEK key

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… 

Documentum Upgrade – dm_DataDictionaryPublisher with wrong target server

As part of the same migration & upgrade project I talked about in previous blogs already (corrupt lockbox & duplicate objects), I have seen a strange but consistent behavior in each upgrade from Documentum 7.x to 16.x versions. During this process, just before the upgrade, a cloning is done to a staging environment, to keep the source untouched.   As…
