#Deployment

I understand this is a rather broad topic (and at times involves religious sentiments) yet I would like to look at it from the Caché perspective:

• Do you use an issue tracking / collaboration system? If so which one. Any you would recommend or immediately dismiss based on personal experience?
• How do you keep track of large code bases? Thousdands of folders named backup1, backups2, ..., SVN, git?
• Do you have a development server to which you commit and test features there, or do you rather run a local copy of caché and implement features locally first, then push to the

I know the next ones:

1. Place all different settings in environment variables. You have a different .env file for each environment, and you must add some code to Production for reading and setting these values. It's good for deploying into containers, but challenging for management when we have a large production. I mean, we have many settings that can vary depending on the environment: active flag, pool size, timeouts, and so on. Not only endpoints.

2. My own case.

Hi guys!

Suppose you developed a tool, framework, library on InterSystems ObjectScript for InterSystems Data Platform, share it via Open Exchange and want people to install it. 

What is the best strategy if it is a library and supposed to be called from different namespaces?

Here are the following thoughts:

1. Tool's developer should be able to use globals to read/store data the tool needs.

2. Tool's consumer should be confident, that the thing he/she installs will not harm the application's data.

3. A tool should be callable from any application's namespace.

4. Tool's installation(in general) should not request manual security changes (e.g. grant the write access to IRISLIB) and %YourClass is not an option.

5. It's easy to uninstall the tool - just delete the namespace/database (maybe delete some web-apps too).

Hi Developers!

Thank you for using ZPM Package Manager and contributing more and more useful packages to the public registry!

But as you already aware ZPM packages are always deployed with source code.

Do you think we need to add the option to deploy without source code - e.g. if you want to deploy a commercial package?

Will you develop commercial modules if there will be an option and deploy it with ZPM?

How do you deploy commercial applications today?

Hi, Community!

Would you please share your best practices for utilising 3rd party modules (say community solutions, frameworks, development tools/utils).

There are two approaches which I like:

1. New namespace for every new module

So, if you install something you install it in special separate namespace/database. MDX2JSON/DeepSeeWeb case.

If the package is intended to be used in other namespaces, map the packages to %All and have it available in all the namespaces in this Caché/Ensemble.

And there is one more benefit: it is easy to uninstall the module, just delete the namespace/database.

The IRIS Installation Guide for Linux, Installation Directory section, says "Do not choose the /home directory, any of its subdirectories, or the /usr/local/etc/irissys directory." but there are no suggestions or any default.

What are your opinions on this? For example, I see that IRIS in a Docker container is installed in /usr/irissys. I'm wondering why that directory was chosen.

The official Linux filesystem docs say:

• /usr is the second major section of the filesystem. /usr is shareable, read-only data.

Hello everyone, 

My team is currently developing guidance and best practices for the generation, storage, and deployment of TUNE TABLE statistics across development and production environments. With that in mind, we want to get an idea of what methods teams in the field have developed for handling this data. In particular, we’d like to know the following: 

1. How often do you use TUNE TABLE in your development vs. production environments? 
2. Do you utilize the $SYSTEM.SQL.Stats.Table package to generate and export TUNE TABLE statistics as files? If so: 
   1. Do you store these in source control?
