Hi,

I want to create a table with a dynamic display of data using the DataGrid.

On the page there dataCombo and the table.

According to the plan, when the user selects an item in dataCombo the table is filled with data. If select another item - data is updated.

But in fact, the data in the table are loaded once when the page is loaded, and when I select value in DataCombo, I receive an error:

Hi all,

We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:

ParentClass has children relationship to ChildClass

ChildClass has parent relationship to ParentClass

In this post I would like to talk about the syslog table. I will cover what it is, how you look at it, what the entries really are, and why it may be important to you. The syslog table can contain important diagnostic information. If your system is having any problems, it is important to understand how to look at this table and what information is contained there.

How do I free licenses?

I have a server with public web application with Unauthenticated access and there seems to be a problem that CSP session ends, but associated license persists for some time (hours). If several users log in, we can hit license limit and all the other users get 503 Service unavailable error.

We are currently debugging it and moving to authenticated web applications, but is there a way to free these licenses quickly?

Here's how it looks like in SMP:

There is a large file that needs to be processed, with over 500 000 rows. Each row needs to be verified for various data and then all the results collated and reported into a single report. What is the most efficient way to do this? I tried calling the processing function with Job , where each function jobbed off would report results to a different node of a common global. But the jobbed functions are not updating their respective rows even though I am passing the global name and root node. What is the most efficient way to process this large file?

Currently, we are running 2014.1 on two different servers (OpenVMS, RHEL). The plan is to transition from OpenVMS to RHEL, but our Write Daemon is in a Troubled state on both servers.

On the OpenVMS server, we have a WIJ file that's 26G and can grow to 40G (size of database cache). Since it hasn't grown to 40G, we don't believe the size of the WIJ file to be the issue.

What else should we be looking at regarding the performance of the Write Daemon?

Is there a way to lock at the record level? I know that you can lock at the table level:

&sql(UNLOCK mytest IN EXCLUSIVE MODE)

but am unable to find a way to lock just at the record/row level.

Would this also affect a SELECT statement done on the record?

Hi everyone

I have a datacombo that displayes value from a db table.

I would like to set one of this value as default value. How can I do that? Is there a way to say selected value given the text or the Id from the DB table?

Thanks a lot and kind regards

Using Oauth2 with SOAP (Web)Services

Hi guys,

Couple days ago, a customer approached me with the wish to enhance their existing legacy application, that uses SOAP (Web)Services so it shares the same authorization with their new application API based on REST. As their new application uses OAuth2, the challenge was clear; how to pass access token with SOAP request to the server.

After spending some time on Google, it turned out, that one of possible ways of doing so was adding an extra header element to the SOAP envelope and then making sure the WebService implementation does what is needed to validate the access token.

Internal Web Service

Hello everyone,

Anyone can help me please. We use SOAP web service with public methods and have many instances of these classes, all work fine. We would like to create a new SOAP web service but for internal usage only, meaning not available to the public. The purpose of this is for communication between different servers internally.

We thought of having the methods to be Internal, WebMethod instead of just WebMethod.

Any suggestions?

Regards

Ben

Hello community,

I recently added a change to our copy of zenutils.js, and while moving it up to production, I found different versions of zenutils.js. I edited a copy stored in the default directory for our web application (e.g. c:\intersystems\DEV\CSP\{application}) but the file on production is stored in {install dir}\CSP\broker.

Validate signature from string

Hello,

We would need to handle the following use case:

A system replies to our GET with a list of codes and a signature.

Each code has been signed with the SHA512withECDSA algorithm

We would need to:

1 Concatenate all codes in a string

2 Decode the string which is in Base 64

3 Validate the string using the signature which we get in the reply

We have read for step 2:

Base64Decode

Parsing null values in JSON

Hello everyone,

I'm creating a REST API with InterSystems Ensemble.

I already have a POST route that parses JSON content into an object defined in a class.

To parse the JSON content, I'm using the JSONStreamToObject method in the Ens.Util.JSON class

Here is how I use it:

AWS SSO Login

Hello,

We are using AWS SSO authentication in our application to validate the users. For validating the users, we are passing the username and password from AWS SSO to our application. We need to validate the user in our application without using the password.

We developed the login class using zenPage. We used <loginForm> tag in the login page which is used for the automatic validation.
Is there any possible way to achieve this?

Thanks in advance.
