Oracle 21c: Blockchain Tables

By | Database Administration & Monitoring, Database management, Entreprise content management, Oracle | No Comments

Oracle Blockchain Tables With Oracle Database 20c/21c the new feature Oracle Blockchain Tables has been introduced. Blockchain Tables enable Oracle Database users to create tamper-resistant data management without distributing a ledger across multiple parties. Database security can be improved by using Blockchain Tables to avoid user fraud and administrator fraud as well. One of the main characteristics of Oracle Blockchain Tables is that you can only append data. Table rows are chained using a cryptographic…

DctmAPI.py revisited

By | Entreprise 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 | Entreprise 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, Entreprise 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…

Documentum – IndexAgent can’t start in normal mode

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

Everybody familiar with Documentum knows that just starting the JBoss/WildFly hosting an IndexAgent isn’t really enough to have the indexing working: the IndexAgent must be started from the UI (or via DA or via the job or via iapi or automatically via the Repository startup or …). Starting the IA in “normal mode” is usually something that takes a few seconds. I faced a few times an IA that apparently didn’t want to start: whenever…

Documentum – xPlore online rebuild stopped because of “immense term”

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

In relation to my previous blog about custom facets not showing up after full reindex, a customer was doing a migration that just completed. After the full reindex, there were no facets because of what I explained in the blog. Knowing that the online rebuild is normally faster than a full reindex, I helped to start this operation but after a little bit more than a day of processing, it failed on a document. The…

Documentum – Custom facets not showing up after full reindex?

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

Beginning of the year, while performing a migration from a Documentum 7.3 environment on VM to Documentum 16.4 on Kubernetes, a customer had an issue where their custom facets weren’t showing up on D2 after a full reindex. At the end of the migration, since xPlore has been upgraded as well (from xPlore 1.5 to 16.4, from VM to K8s), then a full reindex has been executed so that all the documents are indexed. In…

Ansible Custom Interactive Dynamic Inventory

By | Cloud, Development & Performance, Entreprise content management | No Comments

When working with an Ansible dynamic inventory, you may want to update it from your playbook on the fly. For instance, you may want to create a server and then install an application on it without calling a second playbook or developing specific code to create a runtime group (e.g. “add_host” module). Or you may want to update the inventory on the fly without having to wait for an asynchronous mechanism to be triggered. This…

Solr Sharding – Shard creation

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

I wrote this blog in conjunction with the one about the Solr Sharding – Concepts & Methods a year ago and it was 95% completed but then I had other stuff to do and just forgot I didn’t publish it. It might be a little bit late but well, better late than never… It will complete the overview I wanted to share around the Alfresco Clustering and in particular around the Solr Sharding. In this…

Enhancing idql/iapi with rlwrap (part II)

By | Entreprise content management | No Comments

This is Part II of a tour of rlwrap for idql/iapi. For Part I, please follow the link here. Enhanced output visualization This is one rlwrap’s most fantastic enhancement. It is not that different from what I suggested here only much smoother. idql does not provide any flexible formatting and lines longer than the screen width get wrapped around, which results in hard to read output. rlwrap’s pipeto filter lets redirect this output to another…
