Interacting with Users in the Terminal: A Guide to Using %Library.Prompt in IRIS

Have you ever wondered how commands like ^DATABASE engage users in the terminal? Or perhaps you're writing an automation routine and want ways to specify options directly from the terminal. Thankfully, the %Library.Prompt class in IRIS offers a straightforward way to do so!

Atelier Users:

Has anyone found an Eclipse plug-in that provides the capability to connect to a Caché server and give the user a way to write SQL queries using the tables from that server? I'm picturing something like a "WinSQL"-client built as an Eclipse plugin.

I've found and tried the following, but I couldn't get it to connect to my local Caché instance.

Simple problem:

  1. I leave a long-running command in terminal
  2. Switch to another task(s)
  3. Remember that I need to check on my command after a few hours

Is there any way to force terminal to the foreground after current command ends?

This is Windows with cterm/iristerm although Putty/Kitty solution would also be nice.

Hello,

I need to run some clean up routine in the background so loss of my terminal session won't stop the process.

I found the JOB command in the documentation.
JOB | ObjectScript Reference | InterSystems IRIS Data Platform 2022.1

When I try it, it doesn't seem to be doing much. I also expected this to become visible in the Background Tasks but that doesn't happen either.

Probably I am missing something.

I just realized that operating system command execution does not work on Windows console if the IRIS service is started using a different user than Local System account (the default).

I always change the user configured in the IRIS service and I believe this is a standard good practice, particularly in "real" environments (be it production, stage, test or development) that are part of Windows Active Directory Domain.

Hi Devs!

Recently I was impressed by @Daniel.Pasco's article where he shares also how he uses terminal aliases.

Terminal aliases is a very powerful tool for developers and sys admins if you often need to call some cumbersome terminal expressions and make it shorter and cleaner. Here is the documentation.
Yes!

But what about Docker environments? What if you are fan of Docker dev environments but also want to keep using your favorite aliases with Docker as well?

Turned out it is very possible.

Hey Community,

Watch this video to learn how to use terminal aliases for InterSystems IRIS and also how to set it up with your Docker Developer Environment:

Hi, I just installed the TRYCACHE 2016.2.1 preview release into a 16.04 Ubuntu VM. The install is dirt simple. Very nice. I've installed Eclipse Neon and used your update site link to get Atelier. Also very simple and nice. Thank you!

I see there is a January update coming. Will it be possible to include a license that lets developers launch one terminal session while connected to the TRYCACHE instance via Eclipse?

When I try to do this, I'm exceeding the TRYCACHE license limit.

thanks!

Let's say I want to execute this cache script (saved as test.txt) from OS terminal:

zn "USER"
write 1
zn "%SYS"
write 2
halt

Executing the following command in a terminal:

csession cache < test.txt

Would yield this output:

$ csession cache < script.txt

Node: gitlab-test, Instance: CACHE

USER>

USER>
1
USER>

%SYS>
2
%SYS>
Job succeeded

Is there a better way to run these scripts?

Currently I have two problems:

I was searching for the most simple way to connect from visual studio code to my local instance via terminal without having to change any window.

I know this can also be achieved via telnet but seems a bit overhead if you're in your local machine.

For me the simplest sollution is to open a terminal window in VS Code, navigate to the /bin folder of your instance installation and run .\csession.exe INSTANCENAME

For simplicity you can just include your /bin folder in your path so you don't even need to navigate there

For my Embedded Python ONLY demo package I need some user input.
Similar to ObjectScript

read "say somthing",reply

I use the Python equivalent

reply = input("say something")

And this works excellent without problems from Terminal or Doker console

BAD SURPRISE:
with WebTermnial ObjectSscript works fine, but embedded Python fails badly.

For reasons that I won't go into here, I need to run Cache Terminal in Linux using Wine.

It starts up ok, but when I try to establish a connection to a remote server I get the following error:

Ctermsecure Read Error
Could not obtain terminal server client name.
Reason: (10035, 0x2733) unknown error

If I launch CTerm.exe from a command line then I get the following:

hi

I want to online backup one Caché database by windows bat, I find some article from the online documentation about terminal script and the ^DBACK tool and External Entry Points for ^DBACK, so I can invoke the External Entry Points for ^DBACK from terminal script like this: send: Do BACKUP^DBACK<CR>

Is there other better way for backup database from bat/script?

Thanks
