Hi,

I am trying to use the %Net.HttpRequest Class, and the request has to pass through a proxy server that requires authentication.

I am usually able to do that by using the following code:

S httprequest.ProxyServer=proxyServer
S httprequest.ProxyPort=proxyPort
S httprequest.ProxyAuthorization="Basic xyzxyzxyz"
 

I have a problem accessing a site that is accessible only using SSL-

The combination of the proxy authentication code and the SSL code-

S httprequest.Https=1
S httprequest.SSLConfiguration = "XYZ"
S httprequest.ProxyHTTPS=1
 

Does not work- I get the following error:

"<WRITE>zSend+1

Pointers please for debugging a SOAP web-client.

We have several clients in different productions all accessing a web-service. We are trying to add another client in a new production, and its not working. The messages between the relevant Process and the SOAP web-client Operation are the same in the working and the non-working productions. But the web-service is reporting an XML parsing error to the non-working production. Here's the error as reported in the SOAP web-client Operation...

Is there any way to see the output of the web-client Operation - what Ensemble is actually sending out?

ObjectScript allows you to pass any number of arguments using arrays. Do it by adding ... after the argument name.

An example is as follows. In the example statement, the argument information is set in a global variable (a variable stored in the database) so that it can be easily checked after the method is executed.

Class TEST.ARGTEST1 Extends%RegisteredObject
{
ClassMethod NewMethod1(Arg... As %String) As %Boolean
{
 kill ^a
 merge ^a = Arg
}
}

The result of running it in the terminal is as follows.

USER>DO##class(TEST.ARGTEST1).NewMethod1(1,2,3,4,5)

This question is about calling AWS REST APIs. Based on:

http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

AWS requires REST clients to call their APIs using Signature Version 4 which in case you don't know what I am talking about is a pain in the neck.  Here comes the question:

Has anybody, by any chance implemented the v4 signing alg. in COS? If yes, would she or he have the kind heart to share?

Thanks,

In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.

【When importing】

  set x=##class(User.test).%New() // create a new object

On Linux, use the iris command to execute a routine or method from a shell and get the return value.

For more information,  please refer to the document "About Instance Connections".

An example of a command is as follows.

iris terminal instname [arguments]

The return value of a shell script can be specified using a special variable using the Terminate() method of the %SYSTEM.Process class when the process ends, rather than by specifying an argument in the QUIT or RETURN command that is specified when a routine or method ends. Use the method of returning a value to

Is it possible to have a single MUMPS variable representing all subscripts for a global? For example, if I have an ^ABC global and the ^ABC(1,2) node exist, is it possible to have a variable TEMP so that ^ABC(TEMP) would represent ^ABC(1,2)? TEMP="1,2" obviously does not work since it is interpreted as a single subscript, not two subscripts.

Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In the previous part, we created a basic front-end React application. In the second part of this article series I will show how to choose the right back-end technology for your application. You will see Caché allows you to use many different approaches to link your front-end to your Caché server, depending on your application's needs. In this part we will set up a back-end with Node.js/QEWD and CSP/REST. In the next part we will enhance our basic web app and connect it to Caché using these technologies.

The meaning of each timeout value is as follows.

1. [Server response timeout]

If IRIS/Caché processing (routine or query execution) does not finish within this set time, the browser will return an error.

For example, if this value is 60 seconds and it takes 90 seconds to execute a routine/method/query, an error will occur.

2. [Queued request timeout]

For each IRIS/Caché server configured in CSP/REST, you can limit the number of processes that can run CSP/REST concurrently.

For example, when the maximum number of server connections is 3 and if multiple pages tha

Hi,
I am dealing with a very old code base (some routines date back to 1985 and were running on a M system 😉). It is rather huge and currently contains around 5000 compilable *.int routines.

My goal is to export all routine code as *.int UDL files and setup a git repository containing all routines.

The issue is, approximatively 200 of those routines have storage names that differ only in case. I am using Windows and when exporting those routines using vscode, files gets overwritten depending on routine export order, as Windows NTFS file system names are not case-sensitive.

Hello InterSystems Community Members,

I hope you are all doing well. I am currently facing an issue while trying to set up the SNMP subagent functionality for my InterSystems Cache installation.

I am using InterSystems Cache for Windows (AMD64) version 5.2.4 (Build 809_0_9006U). The SNMP subagent functionality requires the iscsnmp.dll dynamic library, which I have been unable to locate in my installation directory.

I have checked my installation directory thoroughly, typically located at C:\InterSystems\Cache, and its subdirectories, but I couldn't find the iscsnmp.dll file.

It can be retrieved using the schema INFORMATION_SCHEMA.

INFORMATION_SCHEMA is a system schema and is not displayed by default in the SQL menu of the Management Portal.

The method to display it is as follows.

1. Open Management Portal → System Explorer → SQL menu.
2. Check "System" on the left of the schema drop-down.
3. Select INFORMATION_SCHEMA from the schema dropdown.

The SQL to get the ID, field name (COLUMN_NAME), data type (DATA_TYPE), description (DESCRIPTION) for the specified table (Sample.Human) is as follows.

SELECTID,COLUMN_NAME,DATA_TYPE,DESCRIPTION

Currently, the SQL privileges (SELECT, INSERT, UPDATE, DELETE) are managed at the tables level, which can be very tedious when you have to administer many roles in an organization, and need to keep them sync with a constantly evolving data models.
By managing privileges at the schemas level, will allow to give SELECT and other DML privileges to *all* or *several schemas* to a role|user, fixing the need to manually synchronize the new tables|views to the roles.

If you agree, I invite you to vote for this idea.
