Documentum – SSL Certificate based secure communication setup

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

Around four years ago, I did a few presentations, here, in Switzerland about “Security & Documentum”. In there, I talked about a lot of different subjects related to both security and Documentum (you guessed it…) like: ciphers, SHA, FIPS & JCE, Documentum & DFC connect mode (characteristics, ciphers, protocols, encryptions, limitations), Documentum & DFC encryptions in transit and at rest (AEK/DBK/LTK/FSK/FEK, TCS, CS Lockbox, D2 Lockbox vs D2 Keystore, Passwords encryption and decryption), and some…

Documentum – Configuration of an IDS Target Memory/RAM usage on Windows

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

A few months ago, I had to work on a Windows Server to setup an IDS Target. The installation and configuration of the target wasn’t that different compared to a Linux host, so it wasn’t difficult at all (if you ignore some strange behavior like described here for example). But there was one point for which I was a little bit skeptical: how do you configure the IDS Target Memory/RAM assignment for its JVM? On…

Documentum – RCS/CFS Upgrade in silent fails with IndexOutOfBoundsException

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

Several years ago, I wrote a series of blogs regarding the silent installation of Documentum Components, including for a RCS/CFS (HA part of a Repository). In there, I described the process and gave an example of properties file, with all the parameters that are needed and a quick explanation for each of them. As I described in the previous blogs, and that is true for most of Documentum components, in case you want to upgrade…

Documentum – IDS on Windows Server not able to start with error 31: device not functioning

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

Documentum Interactive Delivery Services or IDS is a Documentum product that can be useful to publish some documents to an external web server or something similar. It usually works rather well, even if there hasn’t been much changes in the product in years, maybe because it does what it is supposed to do… As a big fan of Linux systems, I pretty much never work on Windows Servers but when I do, somehow, there are…

Documentum – D2 doesn’t load repositories with “Unexpected error occured”

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

I had a case today where all Documentum components were up and running, including D2 but while accessing its login page, the repositories wouldn’t appear and a message “An unexpected error occurred. Please refresh your browser” would pop-up in the lower-right corner and disappear quickly. Refreshing the browser or opening a private window wouldn’t do anything. In such cases, of course the first thing to do would be to make sure the docbroker and repositories…

Documentum – IndexAgent can’t start in normal mode

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

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 seconds. I faced a few times an IA that apparently didn’t want to start: whenever…

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….
