Documentum – E_INTERNAL_SERVER_ERROR on D2-REST Product page related to GUAVA libraries after WebLogic PSU

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

At a customer, the D2-REST (16.5.1) application hosted on WebLogic Server 12c started showing 500 Internal Server Errors, after a customer release including many things. The error was rather simple to replicate since opening the D2-REST Product info page was sufficient (https://<host>/D2-REST/product-info). The URL was returning the following: At the same time, on the logs: 2021-04-26 06:46:20,340 UTC [ERROR] ([ACTIVE] ExecuteThread: ‘2’ for queue: ‘weblogic.kernel.Default (self-tuning)’) – com.emc.documentum.rest.util.LogHelper : LogId: 9b360f83-335a-413e-87e3-481ba5cbf168, Status: 500, code: E_INTERNAL_SERVER_ERROR,…

Documentum – dmqdocbroker/iapi/idql not working because of dbor.properties.lck

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

Have you ever faced an issue where dmqdocbroker, iapi, idql and the likes aren’t able to communicate at all with any Docbroker (connection broker)? Here, I’m not talking about potentially wrong hostname, port or connect modes, which might prevent you to reach a Docbroker if it’s not configured properly because this will still most likely reply to you with an error message… I’m really talking about the utility/binaries that cannot communicate anymore, it’s like all…

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…
