Caché Server Pages (CSP) is both an architecture and toolset used to build an interactive web applications with the InterSystems Data Platform.

Question Yone Moreno · Nov 20, 2023

Hello,

First of all thanks for your time reading this doubt.

We have discovered the following behaviour. Inside a Router we have a roule which needs to filter out the ADT_A08 messages which have not OBXs.

The legacy system had this rule implemented:

(((Document.{OBX(1).SetIDOBX}<"1")||((Document.{EVN:EventReasonCode}!="COD")&&(Document.{EVN:EventReasonCode}!="FIN")))

However we have tested it and it does not filter out the ADT_A08 messages.

Is there any way to express inside a Rule, that we need to discard ADT_A08 messages which have not OBXs?

We have been investigating this class which provides

For routines (*.mac)

You can hide the source by exporting/importing only the *.obj that is generated after compiling the source program.

The command execution example specifies EX1Sample.obj and EX2Sample.obj, which are generated by compiling EX1Sample.mac and EX2Sample.mac, as export targets and exports them to the second argument file.

After moving to another namespace, I am using the exported XML file to perform the import.

USER>do$system.OBJ.Export("EX1Sample.obj,EX2Sample.obj","D:\routine.xml")

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 that take several

The program below works perfectly when I call it directly from the Terminal, however when I call it from within a CSP it does not work (It does not do the SELECT).

In the USER namespace, the program works both in the Terminal and on the CSP , but in another namespace it only works when called directly in the Terminal.

Question Sandeep K C · Aug 23, 2023

Hi Guys,

For Login in CSP application, I am displaying custom Login page which is rendered from subclass CSS.CSP.Login that extends %CSP.Login, and also got IBA.CSP.Page that extends %CSP.Page with overridden method OnPreHTTP(). This setup is working perfectly for normal login.  

When I define Invalid login limit and enable Disable account if login limit reached in System > Security Management > System-wide Security Parameters, the users get disabled after certain invalid login attempts.

Since, cache do not have time period field to disable the account for certain time eg: enable after 15 mins

Question Sandeep K C · Aug 22, 2023

Hi guys,

In Cache CSP application, I have enabled Password expiration days to certain days in System > Security Management > System-wide Security Parameters. When password expires for the users and they try to login the login page takes to standard cache password change page. 

Is there anyway I can display my overridden page instead of standard cache password change page? 

Reason to display my own page:  I needed to break down the UserName, for eg: UserName into CompanyID - IBA and User ID - san.

Currently, I have overridden %CSP.PasswordChange class to CSS.CSP.ChangePassword.cls and included

A bit of an old school CSP question.  <csp:search> is a really nice, quick way to make easy lookups for CSP pages, especially for back office stuff that doesn't need to look pretty for the modern web app user.

At any rate, I'm here at the moment:

<csp:search SHOWSQL=1 NAME="OrgSearch" SELECT="OrganizationName Organization Name,Abbreviation,Software->Abbreviation Software" WHERE="OrganizationName Organization Name,Abbreviation,Software->Abbreviation Software" STARTVALUES=",,Software" PREDICATES="%startswith,%startswith,%startswith" CLASSNAME="AppLibrary.Organization" OPTIONS="popup"

Question Sakthivel Perumal · Aug 16, 2023

I have a webpage in CSP in which there is a link to download files (files are located in specific folder). When the user clicks on the link , it has to download the file into their local machine. Attached code for both upload and download the file from server, upload is working and download is printing the file in webpage rather than downloading it. Appreciate your help.

Upload (Working fine): 

set dir="/usr/bin/local/myfiles/
    Set mimeData = %request.GetMimeData("file")
    Set fileType = mimeData.Attributes("ContentType")

Inspired by a Question from @Evgeny Shvarov and a Reply from @Ashok Kumar T
I have created a base for Global download as XML file

How to use:
 
just call the page like http://<your_server>/csp/samples2/dc.Gdown.cls?GBL=global_name

gbl-name  without the initial ^ (caret)
The output has a default name <global_name>.XML  Your choice is available.

Known Limits:

  • you have to install it at your sourcing server
  • it is not tested/working across namespaces
  • there is no partial download
  • error handling is just basic or missing

There is space for personal improvements.
and this is it:

You can set individual error pages for the following Web Gateway error messages/system responses:

  • server error
  • server busy
  • server unavailable
  • server timeout
  • connection closed

Settings are made on the Web Gateway Management screen ([Management Portal] > [System Administration] > [Configuration] > [Web Gateway Management] > [Configuration] > [Default Parameters]).

In the Error Page section of the Default Parameters menu, set the filename of the html page to display or the URL to redirect to when an error occurs.

Question Michael Davidovich · Jan 31, 2023

When manually coding REST services and using GET /api/mgmnt/v1/:namespace/spec/:application/ to return an OpenAPI spec, how do you specify supported properties (OpenAPI Properties in Use | Creating REST Services | InterSystems IRIS Data Platform 2021.1) like responses, definitions, and information in paths like summary and description?

GET /api/mgmnt/v1/:namespace/spec/:application/ | Creating REST Services | InterSystems IRIS Data Platform 2022.2

Using a very basic manual REST service that returns a JSON string I get a pretty basic spec that is not really helpful when it comes to documentation.

Question Eduard Lebedyuk · Jul 20, 2023

I have the following setup: REST broker calls inProc BO via BS. As BO initialization is time-consuming, I want to reuse the same BO during the CSP process lifetime.

I have tried the following approaches:

  1. Set %session.Preserve to 1 (I would prefer not to use it as the BO object is not linked to a specific client)
  2. Set $$$EnsInProcPersist to 1 (looked relevant)
  3. Cached BS between calls

However, every time I call my REST endpoint, I get a new BO. Is there a way to cache inProc BOs in the CSP context?

To run the sample, import it into any interoperability-enabled namespace, start in.Production pro

In this article I'll cover testing and debugging Caché web applications (mainly REST) with external tools. Second part covers Caché tools.

You wrote server-side code and want to test it from a client or already have a web application and it doesn't work. Here comes debugging. In this article I'll go from the easiest to use tools (browser) to the most comprehensive (packet analyzer), but first let's talk a little about most common errors and how they can be resolved.

Hi,

I have created two CSP pages. One is the Login page and the other page show the patient details from the database.

I want to set the session dynamically just after the successful login and after login it will be redirected to the Patient Details page. If session timeout, then wants to redirect back to the login page.

Thanks in advance.

Question Ben Spead · Apr 25, 2023

I have a csp page that is using embedded Runtime Expression (https://docs.intersystems.com/ens201817/csp/docbook/Doc.View.cls?KEY=RC…) and within that expression I am using a $data() modulo 2 to look for root-level data elements (https://docs.intersystems.com/ens201817/csp/docbook/Doc.View.cls?KEY=RC…).

E.g:

#($select($data(^ImportantFlag)#2:"Important!",1:"Normal"))#

However, my modulo sign (#) after the $data() call is seen as the ending tag for the runtime expression resulting in a broken compilation.

Does anyone know if there is a way to escape )# or just # in a CSP

Any ideas on why my %session.Data array would be wiped out after setting %response.Redirect in OnPreHTTP()?

Context: trying to implement a SSO patter for authorization code flow. I mention this because it's all I can really pinpoint as to what's changing. Typically a user logs in by providing their username/password and we validate in our database and set the %session.Data property with the user info.

Messages.log file contains lots of useful information about IRIS. Sometimes the file gets big, and it is not easy to get to the data I am interested to review. It would be nice to jump to a specific date and time we suspect a problem may have started.

Whenever I need support from InterSystems, WRC will ask to send them messages.log file. Dependent on where IRIS is deployed, it may be cumbersome to obtain messages.log file for sending it to InterSystems.

My team works on deploying IRIS containers in Kubernetes in the cloud.

We have created a number of REST adapters that extend %CSP.REST and these have been working fine.  However, we are now facing a problem with a new one where very large XML documents are being posted.  This is the pattern we are following:

Set inMsg = %request.Content.Read()

Set tSC = ##class(Ens.Director).CreateBusinessService("Epro_ItkHttp",.tBusinessService)

Set tSC = tBusinessService.ProcessInput(inMsg, .tBusinessServiceOutput)
