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…

DctmAPI.py revisited

By | Enterprise content management | No Comments

2 years ago, I proposed a ctypes-based Documentum extension for python, DctmAPI.py. While it did the job, it was quite basic. For example, its select2dict() function, as inferred from its name, returned the documents from a dql query into a list of dictionaries, one per document, all in memory. While this is OK for testing and demonstration purpose, it can potentially put some stress on the available memory; besides, do we really need to hold…

A Simple Repository Browser Utility

By | Enterprise content management | No Comments

A few weeks ago, as the final steps of a cloning procedure, I wanted to check if the cloned repository was OK. One of the tests was to peek and poke around in the repository and try to access its content. This is typically the kind of task for which you’d use a GUI-based program because it is much quicker and easier this way rather than by sending manually typed commands to the server from…

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…
