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…

Connecting to Repositories with the Same Name and/or ID

By | Enterprise content management | No Comments

A rare but recurrent issue that customers sometimes encounter is to how to connect to each one of distinct repositories with the same name or same docbase id, or even both if one repository is a clone of the other one. The present connection resolution technique based on the dfc.properties file does not support this and only lets one connect to the first matching repository found. Well knowing this limitation, why were they created with…

dctmping, A Documentum Repository Checker Utility

By | Enterprise content management | No Comments

When working with containers, the usual trend is to make them as compact as possible by removing any file or executable that is not used by what is deployed in it. Typically, interactive commands are good candidates not to be installed. Sometimes, this trend is so extreme that even simple utilities such as ping or even the less pager are missing from the containers. This is generally fine once a container reaches the production stage…

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…
