Hello again and welcome to the next tutorial on this series: Part 4 - Sharing data across router methods. Here we are going to learn how to share a object containing data that is available for read across every router methods.

You're required to complete at least the Part 1 before entering this one. Still, this is supposed to be a really short tutorial, since there isn't much to be said about data sharing.

"SELECT %SYSTEM.SQL_TableExists('table name') "could work as expected under SQL shell,

but for "CALL %SYSTEM.SQL_TableExists('table name')" does not work (not any error reported, it just show nothing).

Is there any reason why CALL could not be applied to a stored procedure?

Thanks.

Hi

I have been experimenting with the creation of a set of REST services for an app. The basic GET operation is set to create a %ZEN.proxyObject instance, and then set an instance of a Persistant class as a property, which gives me all of the values I want to return. However, it also gives me some values that I don't want to return over REST (because they are both private, and large registered objects which will bog down performance)

Hi Community,

In this article, we will explore the concepts of Dynamic SQL and Embedded SQL within the context of InterSystems IRIS, provide practical examples, and examine their differences to help you understand how to leverage them in your applications.

InterSystems SQL provides a full set of standard relational features, including the ability to define table schema, execute queries, and define and execute stored procedures. You can execute InterSystems SQL interactively from the Management Portal or programmatically using a SQL shell interface. Embedded SQL enables you to embed SQL statements in your ObjectScript code, while Dynamic SQL enables you to execute dynamic SQL statements from ObjectScript at runtime. While static SQL queries offer predictable performance, dynamic and embedded SQL offer flexibility and integration, respectively.

in Management Portal on Freespace screen there are links to compact and truncate a database.

Can these tasks be done programmatically? I have looked through documentation and dont see anything but I hope I just missed it.

Thanks,

David

Cache Studio for Windows 11

Has anyone tried loading Cache 2017 on Windows 11?

I'm working with my corporate IT department to get a version published that will work on Windows 11 desktops but I have to prove that it can be loaded before they will give me the rights to install it.

It looks like Cache 2018 is supported but we're still supporting a bunch of 2017 installations until we can begin the move to IRIS.

Meanwhile the new laptops are all being issued with Windows 11 and the installers are all blocked by corporate.

Hi Guys,

I'm using the below to export a query result to excel file and the only file type is .csv (100) but the resulting has two problems,

first the row header is including the field type and second the resulting file is a tab delimited so columns aren't properly separated (see attached below)

set st = ##class(%SQL.Statement).%New(2,"Sample")
set sql = "select ID, name from MyClass"
do st.%Prepare(.sql)
set type="csv"
set rs = st.%Execute()
do rs.%DisplayFormatted(type,"C:\Temp\report")

I am doing an implementation of a SAML 2.0 SingleSignOn protocol integration which requires a signed message with the signature element in the body of the SOAP message, not the header as is default SOAP security handling. Any suggestions for how to do this would be greatly appreciated. When it is passed in the header, it is not processed by our partner and we just get a "Signature Required" response.

GA releases are now available for the first version (v1.0) of InterSystems System Alerting and Monitoring (InterSystems SAM for short)

InterSystems SAM v1.0 provides a modern monitoring solution for InterSystems IRIS based products. It allows high-level views of clusters and single-node drilled down metrics-visualization together with alerts notifications. This first version provides visualization for more than one hundred InterSystems IRIS kernel metrics, and users can extend the default-supplied Grafana template to their liking.

hi all,

I am looking to make a JDBC connection to my Intersystems Cache using the JDBC driver 2.0.0.

I see the connection format is as "

   jdbc:Cache://<host>:<port>/<namespace>

"

What I really want to do is filter additionally by a certain database, i.e. connect my consuming application to a database under the namespace.

how can I do that? what will be the format

Hi,

I need to route a message synchronously to multiple targets using a routing rule.

In IRIS I built a general routing rule set, made up of a couple of rules. For one Rule in particular, and based on a common condition, I want to send the incoming message to 2 different targets. (no transformation is used)

I can select, in the single SEND action, multiple target names, or, I can create consecutive SEND actions, one after the other, each sending to their specific target.

I'm trying write a JavaScript generator to perform pattern match validations using existing pattern match expressions in a legacy application.

I could make a server call to perform the pattern match operation but is there a way to automatically translate the pattern match expressions into RegEx expressions so I can perform the operation in JavaScript on the client to save making an Ajax call back to the server?

Thanks

When you deploy code from a repo, class (file) deletion might not be reflected by your CICD system.
Here's a simple one-liner to automatically delete all classes in a specified package that have not been imported. It can be easily adjusted for a variety of adjunct tasks:

set packages = "USER.*,MyCustomPackage.*"
set dir = "C:\InterSystems\src\"
set sc = $SYSTEM.OBJ.LoadDir(dir,"ck", .err, 1, .loaded)
set sc = $SYSTEM.OBJ.Delete(packages _ ",'" _ $LTS($LI($LFS(loaded_",",".cls,"), 1, *-1), ",'"),, .err2)

The first command compiles classes and also returns a list of loaded classes. The second command deletes all classes from specified packages, except for the classes loaded just before that.

HTTP request with open stream

Hi Guys,

This link (https://github.com/CassiaNetworks/CassiaSDKGuide/blob/master/node_exampl...) uses Javascript request to open a a steam and collect data in an array (screenshot below) and I'm trying to replicate this with Cache script with HTTP request which is connecting Ok but don't know how can I collect data because the code is hanging at Set tSc=Httprequest.Get(HttpURL) and cannot execute S BLEConnect=Httprequest.HttpResponse.StatusLine or any line after it.

Monitoring IRIS through SAM (sam:1.0.0.115)

While I've used to make it work in the past, I'm not able any more to fix the already faced issue : "State: Unreachable"

Despite all the ip-addresses attempts (or hostname = host.docker.internal) and while "/api/monitor/metrics" is running well...

Could someone provide good practices to make it work cleanly ?

I'm trying to send a POST request to my REST API and I'm getting this error and most likely due the lack of experience, I have no idea how to fix this issue:

"id": "JSONImportError",

"params": [

"AlertText",

Am I missing something from my string definition?
