P2P OAUTH Recommended Flow

Hello,

I'm hoping to get some feedback on the OAuth process flow for Payer-to-Payer authorization. It doesn't seem that "Authorization Code Flow" is needed as there will not be a need for a login. I am leaning towards recommending "Client Credentials Flow", but wanted to get some community feedback before making a decision. I prefer to follow what the standard will be if possible. What would you recommend? Thank you in advance for your input.

InterSystems Developer Community is a community of 17,967 amazing developers
We're a place where InterSystems IRIS programmers learn and share, stay up-to-date, grow together and have fun!

So I am working with an inherited SQL query that queries 8 different tables. 5 of which have over a million records.
I have 3 different servers.

Server 1, Server 2 and Server 3. They all have the same data/tables/structure across all servers.
Server 3 has an Iris database engine and the other 2 are Cache 2015.1.4.

I have a problem with views and performance across the servers being inconsistent.

Thankfully Server 1 is the current live server that performs "fast enough".
Server 2 is being synced from Server 1 and acts as a report server.

I'm trying to save a list of AccessTokens a user for a specific user. This way I could present it together with other user-data.

I have tried calling ##class(OAuth2.Server.AccessToken).OpenByCode(authCode) from %OAuth2.Server.Authenticate's AfterAuthenticate() method. This only returns things like State and AuthorizationCode, but the AccessToken is empty at this point (afterwards it becomes filled out).

Is there a way to achieve storing the AccessToken as part of the login system?

$ZNAME(variable,0)

This function is supposed to tell me that argument 1 is a valid variable name or not.

Doesn't work with an array variable, eg W $ZNAME("WLCOM(I)",0).

Not a question, just a whinge really.....

SQL - use specific index

Hello Community,

we want to use a specific index on our sql-class.

The index we want to use is called "iFilter".
Currently we use the following technique of ignoring all other indices because the automatically chosen index is always too slow.

Have you heard about some restrictions in cookies for tracking visitors to your sites?

One of our clients asked me about how to know really count of visitors.

Their site works on WordPress framework, hosted on classical NAMP hosting.

They can see some statistics from Yandex Metrika conter, but we was not sure about full coverage.

We gave him the AWStats, it takes data from Apache log files on hosting.

iris-analytics-for-money

I regret getting a late start in the InterSystems Analytics contest. I had tried a couple of times before to use Analytics, but I had not gotten too far. I have been recording financial transactions in Excel workbook ever since I had to retire Microsoft Money. Since my iris-for-money was not fully functional, I created a worksheet per account I was tracking. I had developed a CSP page in iris-for-money to import transactions by reading a CSV file.

I'm using FOP 1.1 for ZEN reports and would like to install fonts within the Windows/Fonts directory.

I added the xml tags in fop.xconf but so far I have been unable to get the correct font.

<renderers>
<renderer mime="application/pdf">

<fonts>
<directory>c:\windows\fonts</directory>
<!-- automatically detect operating system installed fonts -->
<auto-detect/>
</fonts>

</renderer>

</renderers>

Any advice would be appreciated.

I'd like to share with you some storage features that also exist in Caché but are almost
unknown and mostly not used. They are of course available in IRIS and gain importance
with large and distributed storage architectures.

I am trying to get a list of databases using the DatabaseByServer method but I am only getting an empty string. I have not found any useful examples of the proper usage of this class/method.

I have tried 2 formats. First

set dbList=""

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList)

I also tried:

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList,"/cachesys/")

In each case dbList is empty string. I can not figure out what I am missing.

Hello,

I am a clinician and we use Trakcare Lab LIMS at our institution.

We understand histopathology reports are directly typed, stored and uploaded directly to the LIMS.

For clinical audit purpose we need to download these reports directly in text format in bulk. Can anyone offer some technical assistance in retrieval of these histopathology reports? Is there any script that can be run to access, retrieve and download these reports?

Previously I have already tried to play with Google Data Studio when I connected it to InterSystems FHIRaaS. It has quite a nice UI, with a few chart types available out of the box, it can be quite easily connected to some plain tables (stored as CSV or JSON, for instance), and gives the ability to build quite flexible analytics over it. So, I have decided to implement a new connector to InterSystems Analytics (DeepSee), with the ability to select a cube and do some queries on it.
