Documentum 16.3 delayed until Feb 2018

If you access the new support page, there is a section where you can find roadmaps for the products, and if you check the Documentum related ones, you’ll see the target date for ths new version listing new features. Without going into much detail (As I’m not sure how public this info is), these caught my atention:

  1. Ongoing exposure of D2 APIs through REST (goodbye DFS?)
  2. Native support for S3 object storage protocols to alleviate storage costs (goodbye OnDemand, hello AWS?)
  3. New REST Services (see #1, no mention of DFS anywhere to be found)
  4. Webtop will get a 16.3 version (yeah!)


Webtop extension will stop working on Firefox 57

In November, Mozilla will release Firefox 57. This version will replace XUL with WebExtensions, this means every addon/extension not developed with the WebExtension API will stop working. The current extension for Webtop is not compatible with WebExtensions:


I wonder if OpenText will show us that they are a “software company” instead of the former Documentum owner which was a “hardware company” and have a new extension ready by the time Firefox 57 is released…

PS: I’m not even sure the extension will work on FF57, as Mozilla hasn’t implemented file access API due to security reasons, so I’m not sure if it’s even possible to port the extension to WebExtensions. (Maybe it is time for a HTML5 transfer mechanism?)

Why Migrate to Documentum D2

I’ve just seen this post by OpenText and I couldn’t resist to add some comments:

One of the striking advantages of a D2 application versus a Webtop application is that upgrades become much easier, and keeping up to date with product development and patches becomes so much easier, because D2 applications are constructed in the configuration framework, and upgrade of the D2 platform does not require ANY work on the configuration.

As long as your business requirements doesn’t force you to develop widgets/extensions/customization of core services. Then you’re in worst position than with other clients, because if Documentum documentation is usually lacking, you’ll be amazed with D2 documentation.

Customers choose their products based on complex weighted matrices of technical considerations, comparing functional details, platform characteristics and implementation approaches before establishing a platform standard within the organization for Enterprise Content Management (ECM).

If any customer would bother to do that, EMC would’ve hardly have sold any xCP 2.0/2.1/2.2 license.

These days, the goal is more likely to be user acceptance, or better put – user adoption –

The goal is selling licences.

By the way, D2 is a good fit (with its own flaws, as Webtop has) if customer sticks to configuration and doesn’t want anything else. Any other case needs to be carefully reviewed before making a decision.


Updated roadmap, webinar and FAQ from OpenText Documentum

If you registered for the webinar OpenText held a few weeks ago (if you didn’t, maybe you can check Andrey’s post on the subject), you should have received an invitation to some site from OT with a FAQ about the Documentum stack. I’m not going to paste it here, just in case it’s not public, but IMHO, the highlights are:

  • Content Server: Aligment with ECD. No new features but trying to move to a microservices architechture. It probably means CS won’t evolve anymore.
  • Webtop: Several points on this. Will keep being supported and updated to support latest CS.
  • Rest: Every new product based on this. No mention about DFS (I hope it’s dead, unless they decide to update with libraries from this decade)
  • xCP: It looks like xCP 1.x support will be over by the end of 2019.
  • Support: Still through EMC’s site until the end of the year.

Multiple environments with Tomcat/DA

Similar to the previous post about configuring dqMan/DQLTester (Multiple environments with dqMan/DQLTester), a Tomcat with DA can be configured the same way:

Folder structure:

  • da.bat
  • bin
  • conf
  • jre
  • lib
  • logs
  • webapps
  • properties
    • env1
      • dev
        • dmcl.ini
      • prod
        • dmcl.ini
    • env2
      • dev
        • dmcl.ini
      • prod
        • dmcl.ini
  • etc.


@Echo off
SET folderbase=dfcproperties

echo ****************
echo 1. env1 dev
echo 2. env2 prod
echo ****************

SET /p var= ^> Choose option: 

if "%var%"=="1" goto op1
if "%var%"=="2" goto op2

SET foldervar=%folderbase%\env1\dev
goto finish

SET foldervar=%folderbase%\env1\prod
goto finish

set JAVA_HOME=%cd%\jre
set\%foldervar%\ -Dfile.encoding=UTF-8 -Xms128m -Xmx512m -XX:+UseG1GC

start "" /D %cd%\bin /B %cd%\bin\catalina.bat start

Mozilla To Drop Support For All NPAPI Plugins In Firefox 52 Except Flash

What does this mean to Documentum? Well, if your Webtop/D2 is using applets (UCF), starting March, you’ll only be able to use it with IE11 and older versions, as no other major browser (actually, Firefox is the only “major” browser that still allows NPAPI plugins, but this is due to their slow pace of development) will allow NPAPI plugins (Java).

D2 (and Webtop and xCP) CTF

CTF (Content Transfer Framework) is how EMC Dell calls their “new UCF”. It works as a browser extension, and is the same extension you’ve used for the latest version of Webtop (new functionality getting first to Webtop? LOL). And this mode is not the default (why?) so you’ll need to change it in the file of D2.

Also, this extension will generate some “index” files on the folder where you download files:

  • .checkout.xml
  • .d2_edit_storage.json
  • .d2_view_storage.json
  • .view.xml

That contain object names, ids, operation performed, and folder paths of the files transferred.

Tested on latest Firefox Nightly x64 and Chrome.

FYI, I’m pasting the “wonderful” ASCII compatibility matrix provided by Dell in the configuration file:

#     +——————-+——+——+——+——+
#     | Browser:OS \ Mode | Thin | Java | ctf  | Note |
#     +——————-+——+——+——+——+
#     | IE 11             | yes  | yes  | yes  |      |
#     +——————-+——+——+——+——+
#     | Edge              | yes  | NO   | NO   | (1)  |
#     +——————-+——+——+——+——+
#     | Firefox           | yes  | yes  | yes  |      |
#     +——————-+——+——+——+——+
#     | Chrome            | yes  | NO   | yes  | (1)  |
#     +——————-+——+——+——+——+
#     | Safari:Mac_OSX    | yes  | yes  | yes  |      |
#     +——————-+——+——+——+——+
#     | Safari:Mac_IOS    | yes  | NO   | NO   | (2)  |
#     +——————-+——+——+——+——+
# Notes:
# (1) Chrome and Edge do not support java applets, and Edge does not support the CTF plugin.
#     D2 will fallback to thin client mode appropriately when java or ctf has been
#     specified in the value of the browser.plugin.mode setting as described above.
# (2) If browser.plugin.mode contains java or ctf, then D2 will silently continue to run in
#     thin client mode. Safari running on Mac_IOS does not support the java or ctf plugin.
