REST and CSP Sessions

Hi!

We are using Rest Service with inheritance of %CSP.Rest, and we are having the following problem: when we receive 100 request from single IP adress - this creates 100 CSP sessions and takes 100 user licence for each request for few seconds. What can we do do about this? We've set this parameter:

Parameter UseSession As Integer = 1;

Thank you in advance!

Hey everyone,

I stumbled across a comment in this post that mentioned that the %SYS.GlobalQuery is a potentially faster alternative to %GSIZE. I tested it out and while I like the %SYS.GlobalQuery I noticed that it has some size discrepancies against a %GSIZE with details. Can anyone tell me which is more accurate for estimating the size of globals?

On one of our servers, when I am in Mgmt Portal and click the link for Configure / CSP Gateway Management, I get this url:

http://ipaddress.of.server:port/INSTANCENAME/csp/bin/Systems/Module.cxw?CSPSYS=0&CSPSYSreferer=_CSP.Portal.Home.zen

but the page displays a 0, and nothing else. Literally, just a 0. This link works on our other servers, with the same URL. Any idea why?

Thanks,

Laura

Hello everyone,

i am in process of changing our authentication method, so we can integrate our AD authentication in our programs. At the moment i am using they %SYS.LDAP object, and trying to use the .Bind() method with the user information to authenticate. This seems to work without issues, but here the problems start.

Dear Colleagues and Friends,

is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.

I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:

$ZF(-100) help.

Hello all!

My company has been switching from $zf(-1) to $zf(-100) like many companies have been. I have been doing fine with 1 argument windows commands such as:

set errorfile = "D:\folder\error.txt"
set outputfile = "D:\folder\output.txt"


set options(1) = ""
set options(2) = "D:\ThomasTools\"

w $zf(-100,"/SHELL /STDERR="_errorfile_" /STDOUT="_outputfile, "dir", .options)

Good afternoon - I am in the process of writing a AngularJS front-end for some CoS functions that my integration team uses for auditing, analyzing and various other purposes. I have re-tooled the functions to return JSON results that AngularJS can then interpret and display. Many kudos to the AngularJS series on this site for giving me a jump start.

Hello,

Last weekend we've updated our Caché version to

Versie:Cache for Windows (x86-64) 2018.1.1 (Build 312U)

I'm using Studio to develop. I've been using the built-in debugger and it has been working nicely. But now, since the upgrade, I'm getting this error when trying to debug any routine or class method:

I want to upload several files using the html tag

< input multiple="multiple" name="BulkFileUpload" type="file">

. The upload.csp page in the SAMPLE namespace only shows how to extract a single file from the MimeData on the %request object. I cannot fathom how to extract multiple files from the MimeData in the %request object in cache. Can some kind soul explain to me how to do that?

Problem starting production

Hope someone can help me, so i was developing a script and during the tests I was using the csession to execute a method. Also i thought i had to stop the instance i was using, so I used the ccontrol stop [instanceName] to stop the instance, but when i restarted the instance i got this error trying to start my production, I have an idea of what's the problem but i don't know how to fix it.

First time post, also a new Cache developer, hence the <Beginner> tag.

If our data has Predefined terms in a dictionary, and a user can add terms on their own, can the terms exist in different tables?

Lets call the tables "Terms" and the user data in "UserTerms".

If a third class definition has a property of "Term" can it not be either Terms or UserTerms?

I'm leaning towards using a Subclass strategy where the pseudo "Parent" (forgive me) is Dictionary.Term and the child is along the lines of Dictionary.Term.User

Hi,

We recently moved our cache instance from windows 2012 to windows 2016 and when i try to now import % routines i'm getting the following error "Unable to obtain a write lock on this routine because either another user has the routine open for editing or you do not have write access to the database the routine is stored in. This item will be skipped."

Let's say we have a class

AbcRequest extends Ens.Request, PropertiesBaseAbstractClass(has all my properties common to all request)

Prop1

Prop2 and so on

Now in my Business Operation

I want to make a json dynamically from this request.

Yes obviously I can do is

Set requestDefinition = ##class(%Library.CompiledClass).%OpenId("MyCreateRequest")
Set JsonObject = ##class(%DynamicObject).%New()

Good morning

I'm probably overlooking something very basic, but I'm running on Win2016 with Cache 2016.2 - All the work I am doing is in INT routines, but I'm making some calls to the Host File system using $ZF(-1).

I have a few mapped Network drives that are mapped in Windows, typically these are locations where I want to back up some files.

My process is quite simple:

1. Read data

2. Zip data files using RAR

3. Create folder on Network drive

4. Move RAR files to new network share.

I've tried a few different commands:

1 607

I have an application using examples from the lottery example in samples name space how do I create a dynamically link based on the data displayed to add a record id to the link

the idea is to loop over the records displays fields and link to edit the shown data at the end of the record in a table format

I've seen a few password change posts, but I wasn't 100% sure it was the same process, so I am asking here. We periodically have to change the passwords for a few Cache user accounts across several servers. Is there a process/script to change these passwords without having to go into the web portal on each server? Thanks so much, and I apologize if this was covered in some of the other articles that I've run across. Just looking for the best method.

How to shrink a WIJ

I have a DR Mirror with a WIJ that is 5 times as large as the Primary Failover member. My Read-Write Reporting mirror WIJs are the same size as the Primary. I don't know why the DR WIJ i so large and would like to shrink it to the same size as the others. Any suggestions are welcome. Thanks!
