#InterSystems IRIS

If anybody could give me some insight on creating the %All Namespace programmatically I would appreciate it. There are quite a few posts I found that reference its creation using the UI, but I cant seem to get passed some validations with any form of the below:

Is there a straightforward workflow in VS Code for moving a class from one namespace to another on the same server? With Caché/IRIS Studio, it was a (sort of) simple export/change namespace in file menu/import operation. But in VS Code it's not obvious (to me, at least).

I can add multiple namespaces to a workspace, but when using isfs:// paths I see only a "Download" option and no "Upload" or "Import/Compile." When I'm navigating the local file tree, I see Import options, but no way to select the namespace into which I want to import.

Hi Community,

We got requirement to Migrate whole interfaces from prod instance (cache2017.1 ) to new instance iris2020.1.

Currently around 100+ integrations (health share and health connect) up and running in prod instance (cache2017.1 ) , we need to migrate this live server to brand new server with iris2020.1.

Could you please suggest me guidelines and best practises while doing this migration.

Please ping me any document reference for this kind of Lift and Shift Migration.

After migration done, we will use new Live (iris2020.1 )instance only.

Hi All, We have been using DeepSee which has been the integrated Analytic Dashboard built over Cache Cubes. It works fine but it's visual capabilities are limited and most probably is getting phased out. If I am not wrong, Tableau is the suggested alternative to DeepSee . It is expensive and a big and considerable shift from existing technology I wanted to get an opinion of the community as to these few key points - What other BI tools others have been using with IRIS and what have been their experience - For which tools are the best inbuilt support / api's avaialble in IRIS

(I wasn't able to find this in the docs or the Community, so feel free to point me to a reference that I missed)

How can I determine the effective User and Group that will be used when an InterSystems IRIS process is doing file I/O on the file system for UNIX? Bonus points if you can tell me how to do it from within InterSystems IRIS as well as from the host OS.

Thanks!

I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?

Hi everyone, i cant understand what is wrong in my query:

ALTER TABLE MyNamespace.MyTable ALTER COLUMN CurrentColumnName RENAME NewColumnName

I just want to rename column name using sql.

I could not find any life example using this syntax.

SQLCODE for this query is -25:

-25 Input encountered after end of query

Quote from documentation:

Hi everyone,

Following the steps I have doubs to configure the options in "Set Server" to send e-mails for hotmail or outlook (smtp-mail.outlook.com).
I dont know how can I configure Mail server SSLConfiguration for hotmail or outlook.
Could you give me help?

Hi,

What is the Python syntax I can use from a ClassMethod (developed in an IRIS using embedded Python), in order to invoke another class method,

- in the same class; and

- in another class.

I see 'self' is synonymous to use $this (..) in ObjectScript, but these are ClassMethods I am invoking, and self did not seem to work.

thanks - Steve

I have defined a class with a dynamic object property:

Class test.Dyn Extends %Persistent
{

Property json As %DynamicObject;

/// do ##class(test.Dyn).test()
ClassMethod test()
{
  do ..%KillExtent()
  for len = 100, $$$MaxStringLength - 1, $$$MaxStringLength, $$$MaxStringLength+1, $$$MaxStringLength *2 {
    set sc = ..save(len)
    write "Len: ",len, " Result: ",$case($$$ISERR(sc), $$$YES: $System.Status.GetErrorText(sc), : "OK"),!
  }
}

ClassMethod save(len)
{
  set json = {}
  set stream = ..getStream(len-8) // -8 because {"a":""}
  do json.%Set("a", stream, "stream")
 
  set obj = ..%New()
  set obj.json = json
  quit obj.%Save()
}

ClassMethod getStream(len)
{
  set stream = ##class(%Stream.TmpCharacter).%New()
 
  if len<$$$MaxStringLength {
    do stream.Write($tr($j("",len)," ","A"))
  } else {
    for i=1:$$$MaxStringLength:len {
      do stream.Write($tr($j("",$$$MaxStringLength)," ","A"))
    }
    do stream.Write($tr($j("",len-i)," ","A"))
  }
  quit stream
}
}

The issue I encounter is that if a length of a serialized json property is more than 3641144 symbols, the object fails to save with the following error (either MAXSTRING or STRINGSTACK):

Length: 100 Result: OK
Length: 3641143 Result: OK
Length: 3641144 Result: OK
Length: 3641145 Result: ERROR #5002: ObjectScript error: <MAXSTRING>%GetSerial+1^%Library.DynamicAbstractObject.1
Length: 7282288 Result: ERROR #5002: ObjectScript error: <STRINGSTACK>%GetSerial+1^%Library.DynamicAbstractObject.1

Is there a workaround? I need to store moderately large jsons (10-15 Mb) and dynamic object properties allow for a very convenient access.

$ZSTORAGE is set to -1.

Hi Community

I have logged final generated json in the object script class using below statement

$$$LOGINFO("JSON = " _newMsg.Read())

where newMsg contains JSON stream, which contains nearly 1000000 + bytes.

I'm using this Dockerfile to build .Net Gateway with my PEX BS. It works fine. If I change the image reference here to store/intersystems/iris-community:2021.2.0.617.0 in line 8 (so update from 2020.2 to 2021.2) it fails to build with:

Hello Community,

to return data from the OnPage() method of a %CSP.Page I used to simply write out the value of a %DynamicArray e.g. via

write tResponse.%ToJSON()

and return $$$OK afterwards.

I am looking for a way to find all properties defined in any given class through coding, including those inherited from parent class(s). In case of inherited properties, I would like to know from which class etc.

A related question: XML adaptor provides a way to export xml schema for a class. Is there a similar method for JSON adaptor to generate a JSON schema for a class?

Thanks in advance for your help.
