This is part II of the 2-part article. See for part I of this article. Testing We will test on the host machine named docker that hosts 2 containers, container01 and container011. All 3 machines run a repository. Its name is respectively dmtest on docker (shortly, [email protected]:1489), [email protected]:1489 ([email protected]:2489 externally) and [email protected]:1489 ([email protected]:5489 externally). Incidentally, the enhanced syntax is also a good way to uniquely identify the repositories. The current dfc.properties file on the host…

Connecting to a Repository via a Dynamically Edited dfc.properties File Now that we have containerized content servers, it is very easy, maybe too easy, to create new repositories. Their creation is still not any faster (whether they are containerized or not is irrelevant here) but given a configuration file it just takes one command to instantiate an image into a running container with working repositories in it. Thus, during experimentation and testing, out of laziness…

An exotic feature in the content server: check_client_version A few months ago, I tripped over a very mysterious problem while attempting to connect to a 7.3 CS docbase from within dqMan. We had 3 docbases and we could connect using this client to all of them but one ! Moreover, we could connect to all three using a remote Documentum Administrator or the local idql/iapi command-line tools. Since we could connect to at least one…

Beside the obsolete dmbasic, the autistic dmawk, the verbose java with the DfCs, the limited iapi (for API) and idql (for DQL) command-line tools, Documentum does not offer any scripting language for the administrator and the out-of-the-box experience is quite frustrating in this respect. It has been so even before the java trend so it is not a maneuver to force the use of the DfCs or to rely on it for administrative tasks. It…

systemd configurations for Documentum systemd has been with us for several years now and has slowly made its way into most Linux distributions. While it has generated much controversy among sysV init hard core, the fact is that it is here to stay and we, Documentum administrators, don’t have our say in this topic. In effect, it does not impact us very much, except that a little translation work is necessary to switch to it,…

This is part II of a two-part article. In part I, we introduced the Documentum repository file structure and saw a first way to transfer content files from one filesystem to another using the repository to get their full path on disk. We saw how to generate an easy to parallelize set of rsync commands to completely or partially copy a repository’s content files. Here, we’ll show another way to do that which does not…

I must confess that my initial thought for the title was “An optimal repository filestore copy”. Optimal, really ? Relatively to what ? Which variable(s) define(s) the optimality ? Speed/time to clone ? Too dependent on the installed hardware and software, and the available resources and execution constraints. Simplicity to do it ? Too simple a method can result in a very long execution time while complexity can give a faster solution but be fragile,…

As the saying goes, “A Picture Is Worth A Thousands Words”. I’d add “And A Simple Graph Is Worth A Long, Abstruse List of Numbers”. And of words too, so let’s show off a little bit: Interested ? Then, please read on. It happens not so infrequently that we wish we could quickly plot a few numbers to have a look at their overall trend. The usual procedure is to output the numbers into a…
