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…
Welcome to part II of a three-part article on extending gawk with a SQLite binding. Part I is here. Part II is followed by Part III, which give some explanations for the code presented here and shows how to use the extension with a stress test. Here, I’ll list the source code of the extension and give instructions to compile and use it in gawk. Beware though that the code should be taken with several…
Quick: what is the most used database management system on our planet ? Oracle ? Wrong. SQL server ? Wrong again ! MySQL ? You’re almost there. It’s SQLite. Surprised ? I must confess that I was too. Actually, SQLite is special in that it is not the traditional 2-tiers client/server but one-tier and embedded, which means that it works as a library linked to an application. As such, it is used to fulfill the…
A few months ago day, as I was writing the documentation for a monitoring probe, I suddenly realized that that probe, along with others I wrote during that time to monitor Documentum installations, had all a big, unexpected flaw. Indeed, it struck me that if it hang for some reason while running, it could stay there well after the next monitoring cycle had begun, which could too be affected by the same problem, and so…
Some time ago, a colleague asked around if someone knew a way to automatically request a rendition right after a document was checked in. This looked like a trigger to me and TBOs are here for that, right ? Sure but there was an additional condition: it should be set up by an administrator from the idql command-line tool as no programming was possible at that time on that system. Given that this tool, along…
Welcome to part III of a three-part article on extending gawk with a SQLite binding. Part I is here. Part II is here. In this final part, I’ll explain succinctly the code that was listed in part II. This part is best read while having Part II opened in another browser window. sqlite_gawk.c Line 48: All the operations on a database requires a handle that is initialized once the database is successfully opened. The handle…
