InterSystems IRIS supports publish and subscribe message delivery. Publish and subscribe refers to the technique of routing a message to one or more subscribers based on the fact that those subscribers have previously registered to be notified about messages on a specific topic.

This article demonstrates how several InterSystems IRIS capabilities can work together:

In this article we would send emails about:

  • New workflow tasks
  • Unassigned workflow tasks
  • Uncompleted workflow tasks
  • Ensemble alerts

Email recipients would be determined using Publish/Subscribe operation and each user would receive only digest email whenever possible.

From the first glance, the task of configuring LDAP authentication in Caché is not hard at all – the manual describes this process in just 6 paragraphs. On the other hand, if the LDAP server uses Microsoft Active Directory, there a few non-evident things that need to be configured on the LDAP server side. Those who don’t do anything like that on a regular basis may get lost in Caché settings. In this article, we will describe the step-by-step process of setting up LDAP authentication and cover the diagnostic methods that can be used if something doesn’t work as expected.

Hi all,

We are moving to IRIS our productions, and everything seems to go fine. But we are facing a problem because we are using the object %Library. CacheObject in some classes, and IRIS doesn't seem to recognize it. At the IRIS documentation (https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic.cls) the object is effectively removed, and I can't find the equivalent.

Has anyone faced this? Which is the new object in IRIS?

Users of analytical applications often need to generate and send out PDF reports comprised of elements of the analytical panel. In the InterSystems stack, this task is solved using the DSW Reports project that is an extension of DeepSeeWeb. In this article, we will explain how to use DSW Reports for generating PDF reports and emailing them.

Hi,

We have Mirroring established between NODE 1 & Node 2 . We have set the "cachesys" database enabled for Journalling. But we dont see the User Accounts , Roles, Resources created on Node 1 ( favoured Primary) reflected on Node 2 . Is creating them manually again is the only option for this ? . Is there any way to sync them or would adding %SYS to MIRROR a possible solution. Would it be great if anyone has faced this as we have an issue that during failovers Team is locked out .

Best Regards,

Arun Madhan

Looking for work

Hi every body

I hope it's the right place & I'm not offending any body.

I'm a veteran Mumps/Cache/Ensemble programmer . I think my only draw back is my age, although my brain is still young & bubbly.

I'm looking a long time for work without success.

I gathered a lot of knowledge & experience during those long years , developed many projects & i'm ready to do any work only to feel useful.

I'll add my resume, I hope & wish that this post will bring some change as I'm desperate to get some work.

WebTerminal : blank screen

I just downloaded and installed the latest WebTerminal into my local copy of Healthshare 2016.2.1

I installed via studio and everything compiled without error.

However when I run it I just see a black screen. The help window at the bottom of the screen pops open when I type '/' but I just can't get any response.

Any suggestions as to how to trouble shoot this?

$match or "?"

Hello all...

Is there two matching patterns in Caché, is there a difference in use one or the other?
Example:

USER>set a = "(1234)"

Using $match.

USER>w $match(a,"\([0-9]{4}\)")

USER>1

Using literal match (sorry if not correctly term expression)

USER>W a?1"("4n1")"

USER>1

What is different from using one or the other?

The 'a?1"("4n1")"' does this pattern exist only Caché.
Exists performance improvement with use pattern Caché?

I think I already know the answer to this but I thought I'd ask anyway. So the Node.js adapter allows you to perform operations directly on Globals. Does the InterSystems.Data.CacheClient.dll or InterSystems.CacheExtreme.dll provide a mechanism to access Gobals directly or are you accessing globals via Caché ObjectScript classes?

This code snippet uses %ZEN.Auxiliary.jsonSQLProvider. The namespace and string of SQL can be edited for different situations. The class method "test" runs the code:


Class eduardlebedyuk.passQuestionParams
{
    classmethod test(pValue = 50) {
        s ns = $Namespace
        zn "samples"
        s tSQL = "SELECT ID, Name FROM Sample.Person WHERE Id > ?"
        s tPR = ##class(%ZEN.Auxiliary.jsonSQLProvider).%New()
        s tPR.sql = tSQL
        s tPR.%Format = "tw"
        s tPR.maxRows = 100
     
        s tParam = ##class(%ZEN.Auxiliary.parameter).%New()
        s tParam.value = pValue
        d tPR.parameters.SetAt(tParam,1)
      
        d tPR.%DrawJSON() 
        //d ##class(%ZEN.Auxiliary.jsonSQLProvider).%WriteJSONFromSQL(,,,,,tPR)  //same thing
        zn ns
    }
}

SQLGateWay performance.

I have a ZEN page with nine tablepanes. Each tablepane queries a table in the same SQLServer db. I have a single SQLGateWay(odbc) to this SQLServer db. I need to get better performance when I query all nine table at the same time. Would my performance improve if I had nine SQLGateWays(nine odbc configurations/connections), one for each query? I would appreciate any and all suggestions for getting the very best performance when using SQLGateWays. Thank you.

I have created a view to stage some data in a different format and then want to reference that view in a SQL query from a table that filters the data from the view using a property of the table.

Example:

select
MsgId,
FileName,
(select
ReportName
from
custom_view
where
MsgId = ReportId
) as ReportName
from
main_table

Is this even possible? When I try this, I get an error table not found for the view?

Hello, our Team is trying to develop Ensemble DTL to transform incoming X12 files into persistent data records. We created a persistent class and we can insert data using SQL. We tried to verify that %Save() gets called by adding %AddToSaveSet() method to persistent class and there writing to a global. We had to extend our persistent class with Ens.VDoc.Interface class or we could not see %Save() being called from Ensemble DTL. We suspect that %Save() gets some kind of error. We tried to debug by overwriting Transform() method in our DTL class.
