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

By | Application integration & Middleware, Entreprise content management | No 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….

Documentum – DARs installation fails Java 11

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

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 tried to adapt since Documentum 16.4 (and kind of failed) but that’s not really the…

Documentum Upgrade – Castor is locked!

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

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 ever see locked objects after the upgrade, then something probably went wrong somewhere.   In…

Documentum – Change/Rename of LDAP Config object

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

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 LDAP Server Config inside Documentum (including its name). This is probably something that you will…

Documentum Upgrade – Missing DARs after upgrade

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

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 installed properly. This makes it rather difficult to anticipate since you basically don’t know what…

Documentum – D2-REST Privileged Client utility 16.7+ fails with class not found

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

In previous blogs, I already talked about how to fix issues with the D2 Privileged Client utility (for 16.4.0, 16.5.0 and 16.5.1) as well as how to execute/use this utility for automatic/silent registration & approval of DFC Client IDs. I’m now back to this topic because I had the opportunity recently to work with D2-REST 16.7.1 so I took some time to compare the 16.7.0, 16.7.1 and the newly released 20.2 versions as well of…

Documentum Upgrade – Switch from Lockbox to AEK key

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

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 exact, upgrading to 16.7 or above in place (using VMs for example) is normally going…

Documentum Upgrade – dm_DataDictionaryPublisher with wrong target server

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

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 part of this cloning, an update of the target_server value of the dm_job objects is…

Documentum Upgrade – Duplicate JMS and ACS config objects

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

I have seen several times in the past duplicate JMS and/or ACS objects created by OpenText (and Dell/EMC before) installers. I opened several tickets with the OpenText Support over the past 4/5 years to try to get a reason and a fix (had the issue with all versions, 7.1, 7.2, 7.3, 16.4). The first few tickets (2 or 3, I don’t remember) always ended up after several months of investigation with no real solution and…

Documentum Upgrade – Corrupt Lockbox with CS 16.4

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

A couple months ago, I was working on an upgrade project from Documentum 7.x to 16.4. During this upgrade, I faced a few issues so I will try to write some blogs about all that in the coming weeks, starting today with an alleged “corrupt” Lockbox. This upgrade was part of a migration as well from Virtual Machines to Containers (using Kubernetes), therefore the upgrade was done on a staging environment build specifically for that…
