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 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…

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…

Testing the log watcher This is part II of the article. Part I is here. All the above code has to be included in the entrypoint script so it gets executed at container start up time but it can also be tested more simply in a traditional repository installation. First, we’ll move the code into a excutable script, e.g. entrypoint.sh, and run it in the background in a first terminal. Soon, we will notice that…

Containers running under docker can have their stdout observed from the outside through the “docker logs”command; here is an excerpt of its usage: docker logs –help Usage: docker logs [OPTIONS] CONTAINER Fetch the logs of a container Options: –details Show extra details provided to logs -f, –follow Follow log output –since string Show logs since timestamp (e.g. 2013-01-02T13:23:37) or relative (e.g. 42m for 42 minutes) –tail string Number of lines to show from the end…

Stopping the unreachable repositories Suppose that the docbroker has been stopped prematurely and that we want to shut down the repositories but the out-of-the-box dm_shutdown_repository is not effective. Why is it so by the way ? If we look closely inside the shutdown script, we quickly notice the reason: #!/bin/sh ################## DOCUMENTUM SERVER SHUTDOWN FILE ###################### # # 1994-2018 OpenText Corporation. All rights reserved # Version 16.4 of the Documentum Server. # # A generated…

You have finally completed that migration and need to restart all the Documentum processes. So, you shut down the docbroker and move on to the repositories but then you receive an error message about them not being reachable any more. Or conversely, you want to start all the Documentum processes and you start first the repositories and later the docbrokers. Next, you want to connect to one repository and you receive the same error message….
