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,…
A customer recently contacted us regarding an issue with an old Alfresco Enterprise 4.2.2 environment. The system had been running stably for years, with a nightly restart of the Tomcat/Alfresco service to help recycle the memory and fix long-standing issues in this version. Earlier this week, one of these nightly restarts suddenly failed and since then, Alfresco would completely refuse…
I recently asked myself this question after having been confronted with a quite challenging situation, which will be been dissected in this post. Indeed, most of the DBA are aware about several mechanism offered by the Oracle database engine to call external programs.However, we rarely have the opportunity to get deep understanding of all of them due to the broad…
If you are familiar with Java, you probably know that starting with JDK 9, you may need to add some “–add-exports” or “–add-opens” parameters to the JAVA_TOOL_OPTIONS. This is the Strong Encapsulation, which started with JDK 9 and was only displaying warnings until JDK 16. With Java 17, however, it is now fully in effect so you may start seeing…
In a previous blog post, I explained how to monitor Apache Tomcat with Prometheus with help of JMX exporter. It is not always desirable to use JMX as it requires: Fortunately, it is possible to instrument a JVM directly with an additional javaagent argument. Java Agent Once we downloaded the java exporter from github repo, we simply need to add…
One of the most common errors while running an application is “out of memory”. And Java is no different besides errors being named exceptions. The exact exception name you might have encountered is: And, in most cases, it is related to Java heap. I will go through a few reminders on what Java heap is. How it works and how…
BMC Software requests yearly a licencing report of the usage of Control-M at the customer site, for that they send you a request to generate a report by using a Usage Reporting Tool provided by them and send back the the generated Report. When I tried to use the tool, I encountered an issue (java), I was using the version…
At a customer, I recently faced a problem with the JMX settings that couldn’t be reverted. If you already worked with Alfresco, you know that it’s possible to save configurations through the Alfresco Administration Console and that doing so will store these settings into the Database. This has several drawbacks like the fact that it’s then impossible to manage your…
This post is about two security vulnerabilities reported on log4j 2.x framework: CVE-2021-44228, with a base score 10 (of 10 max.) in CVSS version 3.1 risk, and CVE-2021-45046, base scored 9.

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…
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,…
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…
