How do I run OpenERP Web 6.1 on a different machine than OpenERP server?
In 6.0 this was easy, there were 2 config files and 2 servers (server and "web client") and they communicated over TCP/IP.
I am not sure how to setup something similar for 6.1.
I was not able to find helpful documentation on this subject. Do they still communicate over TCP/IP? How do I configure the "web client" to use a different server machine? I would like to understand the new concept here.
tl;dr answer
It's meant only for debugging, but you can.
Use the openerp-web startup script that is included in the openerp-web project, which you can install from the source. There's no separate installer for it, as it's not meant for production. You can pass parameters to set the remote OpenERP server to connect to, e.g. --server-host, --server-port, etc. Use --help to see the options.
Long answer
OpenERP 6.1 comes with a series of architectural changes that allow:
running many OpenERP server processes in parallel, thanks to improved statelessness. This makes distributed deployment a breeze, and gives load-balancing/fail-over/high-availability capabilities. It also allows OpenERP to benefit from multi-processor/multi-core hardware.
deploying the web interface as a regular OpenERP module, relieving you from having to deploy and maintain two separate server processes. When it runs embedded the web client can also make direct Python calls to the server API, avoiding unnecessary RPC marshalling, for an extra performance boost.
This change is explained in greater details in this presentation, along with all the technical reasons behind it.
A standalone mode is still available for the web client with the openerp-web script provided in the openerp-web project, but it is meant for debugging purposes rather than production. It runs in mono-thread mode by default (see the --multi-thread startup parameter), in order to serialize all RPC calls and make debugging easier. In addition to being slower, this mode will also break all modules that have a web part, unless all regular OpenERP addons are also copied in the --addons-path of the web process. And even then, some will be broken because they may still partially depend on the embedded mode.
Now if you were simply looking for a distributed deployment model, stop looking: just run multiple OpenERP (server) processes with the full stack. Have a look at the presentation mentioned above to get started with Gunicorn, WSGI, etc.
Note: Due to these severe limitations and its relative uselessness (vs maintenance cost), the standalone mode for the web client has been completely removed (see rev, 3200 on launchpad) in OpenERP 7.0.

I have inherited a Read The Docs in-house installation (to see our internal git server), in which it was a known issue that the build volume would eventually run full. Now it has again and we would like to find the proper solution. We currently run in Openshift and to my understanding the build job runs "next to" the web server and communicate through shared volumes, including a build volume.
It appears that the problem is that old builds (notably Pull Requests) are not deleted but stay for ever on the build volume. I am not a Django programmer so I am unfamiliar with these kind of applications making the spelunking challenging.
Is this a simple setting about cleaning that my ex-colleague have missed, or where should I look in the sources? The last thing he did before leaving was upgrading to 6.0.
I am interested in evaluating PhpStorm. I am currently a VSCode user but want tighter integration with my PHP development.
The only feature I see that might be a show stopper is not having a Remote Development feature. A lot of the codebases I work on do not reside on my local machine.
Does PhpStorm currently have this option? Specifically, this has proven to be very beneficial in my day to day operations: https://code.visualstudio.com/docs/remote/ssh
Does PhpStorm have remote development built into it?
PhpStorm doesn't have this Remote Development (with SSH) feature currently.
Though you could use it to edit remote files directly with SSH: https://www.jetbrains.com/help/phpstorm/editing-individual-files-on-remote-hosts.html but debugging, refactorings, and some other IDE features are not supported for such files.
We do consider supporting the workflow for full remote development support, when you're having sources in one place, building them in another and opening an editor in the third one, but we do not have particular plans to share or ETAs for it, sorry.

Classical Dynatrace monitoring worked by using an agent for monitoring java processes. You had to add the agent to the monitored VM and it worked.
Dynatrace OneAgent does this without agents. But how does it work. There was no agent added to the Java process. All that is needed is restarting the Java process. Tried it out with Liberty Server and could find two Dynatrace threads called ruxitautosensor and ruxitsubpathsender. But i do not understand how the injection works.
Dynatrace OneAgent changed the "/etc/ld.so.preload" file in OS:
/$LIB/liboneagentproc.so
"/etc/ld.so.preload" and env variable "LD_PRELOAD" are used to preload specified lib when starting new process.
It seems to me they are using standard JVM Tool Interface APIs.
-agentpath:<path-to-agent>=<options> to JVM.
Full documentation here: https://docs.oracle.com/javase/8/docs/platform/jvmti/jvmti.html
Example:
-agentpath:C:/PROGRA~2/DYNATR~1/oneagent/agent/lib64/oneagentloader.dll=isjdwppresent=true,loglevelcon=none,tenant=00000000-0000-0000-0000-000000000000,tenanttoken=XXXXXXXXXXXXXXXX,server=https://10.10.10.10:8443/communication
Note: Some strings have been obfuscated.
On a very high level the installed OS-level agent runs some processes which use OS-level functionality to iterate processes on the machine and inject the agent via various different techniques into all the technologies that are supported for "deep monitoring", e.g. Java, .NET and a number of others.
More details are likely not published for obvious reasons as all this gives a clear advantage compared to the traditional approach for injecting agents manually via adjusting startup scripts, especially if you are deploying into a very large environment.
There are many tools for managing the configuration of infrastructure like Chef, Puppet etc But are there any tools that aid with the pain of managing the configuration of desktop applications?
So, as an example, you have an environment with 150+ different legacy desktop applications (most internally developed with some 20+ years old). Each of those applications can run in at least 3 different environments (eg Dev, Test, Live), some can have many more environments. Some applications can be running with different versions. With all of these variants you end up with hundreds if not thousands of configuration files. How can you centrally manage the configuration of the applications so that you can handle scenarios such as "Database server xyz is being replaced with zyx, we need to repoint all relevant application configurations".
The answer we have currently is to amend the apps so that at start up they call out to some form of central configuration management server, announcing the apps name, version and the environment it's in and the central server responds with the correct configuration. But is this the right approach and if so, why can't I find any off the shelf products that would handle this, surely others have this issue as well?
There are other issues as well around handling different configuration types, such as registry settings, ini files, config files, etc., but they can all be managed with the data returned from the central server. There are also issues around the dependency on the configuration server, but they can be handled with caching of configuration and other techniques.
We currently have an application that runs on one dedicated server. I'd like to move it to OpenShift. It has:
A public-facing web app written in PhP
A Java app for administrators running on Wildfly
A Mysql database
A filesystem containing lots of images and documents that must be accessible to both the Java and PhP apps. A third party ftp's a data file to the server every day, and a perl script loads that into the db and the file system.
A perl script occasionally runs ffmpeg to generate videos, reading images from and writing videos to the filesystem.
Is Openshift a good solution for this, or would it be better to use AWS directly instead (for instance because they have dedicated file system components?)
Thanks

The shared file system will definitely be the biggest issue here. You could get around it by setting up your applications to use Amazon S3 or some other shared Cloud file system though fairly easily.
As for the rest of the application, if I were setting this up I would:
Setup a scaled PHP application, even if you set the scaling to just use 1 gear this will allow you to put the MySQL database on it's own gear, and even choose a different size for it, such as having medium web gears (that run php) and a large gear that runs the MySQL database. This will also allow your wildfly gear to access the database since it will have a FQDN (fully qualified domain name) that any of your applications on your account can reach. However, keep in mind that it will use a non-standard port instead of 3306.
Then you can setup your WildFly server as whatever size you want, but, keep in mind that the MySQL connection variables will not be there, you will have to put them into your java application manually.
As for the perl script, depending on how intensive it is, you could run it on it's own whatever sized gear with some extra storage, or you could co-locate it with either the php or java application as a cron job. You can have it store the files on Amazon S3 and pull them down/upload them as it does the ffmpeg operations on them. Since OpenShift is also hosted on Amazon (In the US-EAST region) these operations should be pretty fast, as long as you also put your S3 bucket in the US-EAST region.
Those are my thoughts, hope it helps. Feel free to ask questions if you have them.
