Documentum

OpenText Documentum as our consultants run it: installation, upgrades, Content Server, D2, xPlore, administration, scripting and troubleshooting.

OTDS – Installation of Replicas fail if the OT Admin password is too long?

For simplicity, in this blog, I will refer to the first OTDS instance as the “Primary” (the synchronization master host, installed with ISREPLICA_TOPOLOGY=0=FALSE) and any additional instances as “Replicas” (installed with ISREPLICA_TOPOLOGY=1=TRUE). Over the past few years, I have installed and worked on around 20–30 different OTDS environments, some with a single instance and others with multiple instances (HA). Overall,… 

Dctm – Another DM_LICENSE_E_INVALID_LICENSE error but caused by JMS this time

At the end of last year, I published a first blog about a DM_LICENSE_E_INVALID_LICENSE error in D2 SSO login through OTDS. The root cause in that previous post was a duplicate user with one lowercase and one uppercase user_login_name. However, I did mention that there can be several reasons for that error. In this blog, I will describe another such… 

Dctm – IDS Source 16.7.5 config.bin crash during execution

Around six months ago, I faced a confusing issue with IDS Source 16.7.5 where the “config.bin” executable always crashed when I tried to run it. The installation of IDS binaries itself completed successfully without any errors. However, the configurator, which is supposed to set up the required objects inside the Repository, consistently crashed. 1. Environment context and IDS upgrade This… 

Dctm – Upgrade from 23.4 to 25.4 fails with DM_SERVER_E_SOCKOPT

Since its release in Q4 2025, I have worked on several upgrades from 23.4 to 25.4. The first one I worked on was for a customer using our own custom Documentum images. If you have followed my posts for some time, you might recall a previous blog post where I discussed a Documentum 20.2 to 23.4 upgrade and some issues… 

Dctm – Detect and analyze slow SQL queries

Documentum is a powerful but also complex software. Therefore, debugging performance issues often comes down to being able to implement and review various traces. In this blog, I will talk about how you can detect and analyze slow SQL queries from a Documentum Server. Several years ago, I wrote a blog post about DFC traces. It included the setup and… 

Dctm – Managing licenses through OTDS

As you might know, since Documentum 24.4, there is a new requirement to have a valid license assigned to a user in order to log in to Documentum. This is a pretty important change, most likely designed with the X-Plan license model in mind, and one of the reasons why OpenText changed the license approach in the first place. This… 

Dctm – Incorrect r_object_id reference in OTDS

I recently faced another pretty interesting case with an incorrect r_object_id reference in OTDS. In a non-production (dev) Active Directory (Azure EntraID) that is used as source of truth for the users/groups, it looked like there was an account which was a bit messed-up. By that, I mean that the mail address, user name and other fields from that account… 

Dctm – MFA & non-MFA within OTDS based on target Applications

In OpenText Directory Services (OTDS), you have multiple ways to handle two-factor authentication (2FA) or multi-factor authentication (MFA). As a quick reminder, 2FA is simply the fact that you need to prove your identity in 2 different ways (e.g. a username/password + a One-Time-Password or a token or a biometric signature or …) while the MFA is at least 2… 

Dctm – OTDS SSO with sAMAccountName AD/LDAP attribute and Azure

The OpenText Directory Services (OTDS) is a pretty interesting piece of software, and it works quite well out-of-the-box. If you are starting to use the OTDS from scratch (when you have nothing internally), then there isn’t much problem, you can just use what they provide OOTB and that’s fine. But for big companies or if you already have a lot… 

Dctm – D2 SSO through OTDS fails with DM_LICENSE_E_INVALID_LICENSE

After doing some more upgrades from Documentum 20.2 to 23.4, including D2, I faced a funny error about invalid licenses (DM_LICENSE_E_INVALID_LICENSE) while trying to login to D2 through OTDS SSO. That’s interesting because there is no license management for Documentum in 23.x, it only starts from 24.4 onwards. This is the (pretty) error in question: As a disclaimer, this customer… 

Dctm – Configure the memory of an IDS Target on Windows

The Documentum Interactive Delivery Services (IDS) doesn’t seem to be very popular, at least in my experience, as I haven’t seen that one used in a lot of situations. However, when I did, I always had to increase the IDS Memory, as the default JVM was never enough to process an actual production load. Memory configuration on Linux On Linux,…
