Hello,

Recently I have been required to work with a method called ExportToStream.

The situation asks me to export a UTF-8-encoded JSON as a XML to be imported on old releases. Here's how I attempted to fulfill this request:

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

Hi,

I'm trying to read a TIF file using ObjectScript.

I know that it is possible to achieve using python or R, but I don't know how to do it using ObjectScript.

If anyone has done it before and has some advice, I really appreciate it.

Best Regards,
Henrique

How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.

The current jdbc driver version is 3.1.0, but it is not published in the public mvn repository, only the old version, see:

https://mvnrepository.com/artifact/com.intersystems/intersystems-jdbc

It is very bad to the Java Community. And why not publish IRIS Hibernate dialect in mvn repository too?

These actions are important to Java Developers.

Is there a way to query a SuperServer port to get the version of IRIS / Caché instance? Ideally, I'd want to do this with a raw socket connection.

I have the variable with literal.

Can I understand with ObjectScript that the literal is:

%String,

or %Integer,

or %Date,

or %Double,

or %Numeric?

What I'm looking for could be:

set variable="To be or not to be"

USER>w ##class(utils).GetType(variable) 

%String

set variable=42

USER>w ##class(utils).GetType(variable) 

%Integer

Hi.

Is it possible to convert the object of type %SerialObject to $List form? I'm using embedded class in unique index and I want to use autogenerated method Open to access the object - parameter should be in $List form...

Tnx.

Hi,

I don't like the default terminal very much because it can't change the window size freely.

How to use CMD or PowerShell?

The question is pretty much in title. I'm developing a REST API, it has a search endpoint with 10 optional parameters. How do I pass them and stay RESTFul?

To ease the question a bit let's agree that:

• all parameters are AND parameters, user can't make combos, ORs, etc. User can only provide values
• all values are integers so I don't have to think about URL limits
• all values are atomic
• all conditions are about equivalency

Some options I know of:

1. URL parameters.

Hello Respected members,

I am new with InterSystems IRIS , want to setup the environment on RHEL 7.5 with multiple lun layouts (separate LVM for DB , Journal, and WIJ),

I would like to get some help in setting up the same, as far as I know, the installation will go through on a single directory ( I did not see any option to chose path/directory for DB's or WIJ /journals), hence after installation I would like to move my DB's to separate LVM and WIJ on another LVM set

I am doing a HL7 data transformation with object script but need to only write a substring from the first "(" of the NTE-3 field to the end.

example

Input: NTE|1|||Some text (HI) (321)|ABC

Desired Output: NTE|1|||(HI) (321)|ABC

Basically I'd like to delete "Some text ".

If I were writing a shell script I would use sed 's/^.*(/(/' with perhaps a modification to get only the first.

I use the function wizard but can't seem to get the right code.
