I've been accessing Cache tables from a developer/reporting side, but am now involved in a project to create a data warehouse for our application. I'm trying to find a query I can use to return the sizes of all the tables in the database, so we can identify the largest tables and handle those individually. Can someone give me a query I can run against our Cache database to return the sizes of all the tables from largest to smallest?

Thanks for the help

Problem with sftp

Hello, everyone,

I have the problem that when trying to connect to the SFTP server the error appears, the user and password are wrong. However, these are correctly stored under login data and I entered! SFTP in SSL Config. The connection works wonderfully with Filezilla. Anyone else has a tip for me?

Newbie

I am currently running a docker image with Iris 2021.1 and I would like to install node js on to it. I have had a look at the instructions on the intersystems online learning portal and I must say its very confusing. Some of the documentation says that you can only install it on 2019. Other parts say that it doesn't matter and you can install it if you have a dev directory. I checked my dev directory and there it isn't there. Sadly this is very inconsistent. Does anyone know if it is possible to install on the above mentioned version of Iris ?

When i use &sql(SELECT ......) in Cache I can watch the generated code
In the generated .int code and see what is happening.
Just with my normal rights

Now in IRIS I have just 4 line calling some class %sqlcq.***
With enough rights i find there is no such class but the generated .int routine
%sqlcq.IRISAPP.xEZgUjdXCCgQdZQPpRdOye1Ci2ue.1
That holds the code that i had in my .int on Cache

Can i switch this back somehow ?

Good day,

I'm trying to get IRIS to run on a new MacBook with a Apple M1 Pro chip. Local installs did not run, so I switched to docker containers. When I execute following command "docker run --detach --publish 52773:52773 --volume /Users/joost/Docker/iris/data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 --init store/intersystems/iris-community:2021.1.0.215.0" an image is pulled and a container is created but the IRIS instance does not run. The log gives me the following output:

Why? How? What's zap-api-scan-sample?

Hey community, how are you all doing?

What if you could check if your REST application is susceptible to some vulnerability? What if you could check if any known attacks affect your application?

With these issues in mind, we've brought our sample application using the ZAP testing tool. A way to quickly, conveniently provide tools for developers to validate security issues in an accessible manner practically.

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are:

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

Hi Dev Community,

I have a persistent Document class that has a FileName string property and another Question class that has an optional one-to-many relationship with Document.

I'm trying to add a SqlComputed property to the Question class (docFileName) where docFileName = Document.FileName if there is a related Document or an empty string if there isn't one.

I'd prefer the property to be SqlComputed so that if Question.Document changes, Question.docFileName will automatically update.

Leveraging the Audit database

The InterSystems IRIS has a great audit system. It is responsible for auditing system events, but you can use it to audit your applications (great feature).

The audit system is based into event concept. The events can occur with IRIS or in an application. So, we have two type of events to the audit system:

1. System events: events occured into the InterSystems IRIS components (database, interoperability, analytics and core);

DTL Transformations and GetValueAt/SetValueAt calls on HL7 messages will truncate any fields longer than 32K. To avoid this, the methods GetFieldStreamRaw and StoreFieldStreamRaw must be used when dealing with fields that might be larger than 32K. OBX:5 is a frequent example. These methods have some subtleties and must be used carefully.

This can't be done by simply dragging from left to right in a DTL. It must be done with a code action. Also, the StoreFieldStreamRaw call must be the last edit made to the segment because the segment becomes immutable after that.

We are seeing ERROR #5002: Cache error: <MAXSTRING>zSaveData+14 ^EnsLib.HL7.Segment.1 come up on a Routing rule when we are trying to Encoded PDF's through a DTL. In the DTL we are copying source to target. Is there a limitation on trying to copy source to target?

At the bottom of the DTL you are see that we commented out converting the Encoded PDF to a Stream, is it recommended that we always use %Stream anytime we are dealing with PDF's?

Thanks
