#Caché

Hello, community.

I've been working with Intersystem Caché for two years, and right away I was excited about the rich ecosystem that Caché provides. However, I was disappointed with calls using #call, and I understand that it was a limitation of the time. Well, the frustration is that #call returns null by default, meaning an AJAX request is executed, but there's no hook to retrieve the return from that request. The only way to retrieve the data from that request is by building a callback on the server side using &js<>.

Hi everyone,

I'm working on a requirement to generate and export medical reports to PDF using Logi Reports. The core requirement is that each generated PDF must be encrypted (password-protected), and the password needs to be dynamically set to the specific Patient's Date of Birth (DOB).

Currently, the report is populated using a Stored Procedure as its data source.

My questions are:

1. Is there a built-in way or API in Logi Reports to dynamically set the PDF export password using a field returned from my dataset (e.g., taking the Patient_DOB column from the Stored Procedure)?

Was wondering if anyone had a Dynamic way to see if a Global is still being used by a Class File. 

We have been monitoring our Global Size recently, and I am trying to find problematic Class files that are not being cleaned up or used appropriately. I have come across some globals that do not seem to have a Class attached to them anymore, and instead of deleting globals 1 by 1, I was looking for a way that we could dynamically do this since the globals have data that is stale in them.

Thanks

Scott

I am connecting to an intersystems cache database via C# and I need to obtain a list of all available namespaces.

I am using code like this:

           var C = new InterSystems.Data.CacheClient.CacheConnection(CS);
           C.Open();
           var Command = C.CreateCommand();
           Command.CommandText = $@"
               select * from %SYS.Namespace_List()
           ";
           var Values = Command.ExecuteReader();
           while (Values.Read()) {

Hi Team,

We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.

Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?

Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.

Thanks,
Ganesh

We didn't start with a big AI strategy.

We had a legacy InterSystems Caché 2018 application, a lot of old business logic, and a practical need: build a new UI and improve code that had been running for years. At first, I thought an AI coding agent would help only with a small part of the work. Maybe some boilerplate, some REST work around the system, and a bit of help reading old ObjectScript.

In practice, it became much more than that.
