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.

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
    }
}

Hello,

I am a beginner with Object Script and I hope anyone can help me solving my questions.

1. Is there a way to time a loop in Object Script?

2. My code leads to the following error, even though it executes the method.

Is there a way to ignore this specific error, so that I can repeat my code in a time loop over and over again without stopping?

Wireshark with ensemble

Hi,

We see a lot of TCPIP connection error for few of the components not sure if it is a network glitch at the source/target or is it with us. And most of the times these errors are very transient and vanish on their own and the connection gets re established and the messages get processed. Here is the error we mostly see

ERROR <Ens>ErrTCPTerminatedReadTimeoutExpired: TCP Read timeout (30) expired waiting for terminator SegTerminatorAscii=13, on |TCP|50007|10620, data received =''

%NOLOCK in insert query

I would like to know , if its safe to use %NOLOCK in insert query while doing some parallel processing in Ensemble. We will have pool size of more than 1 for a business process. The business process does an entry in internal meta data table , which will be used for some internal reporting. The same row might get updated by some other process later point of time. i could not produce any error or any issues . Looking forward to hear some opinion on this.

Method to Create a Class

The following class method "test" contains code that can create a new class, create new properties for classes, or create new methods for classes. "test" runs all three of these processes once, and the code that performs each action is labelled by comments in the method:


ClassMethod test() As %Status
{
    set sc = $$$OK
    
    // Create a class
    set class = ##class(%ClassDefinition).%New("MyClass")
    set class.Description = "This is my test class"_$c(13,10)_"testing %ClassDefinition"
    set class.Super = "%Persistent"

    // Create a property and add it
    set property = ##class(%PropertyDefinition).%New("MyClass.MyProperty")
    set property.Type = "%String"
    set property.Description="This is a property"
    set sc1 = class.Properties.Insert(property)
    do:$$$ISERR(sc1) $system.Status.DisplayError(sc1)
    set sc = $$$ADDSC(sc, sc1)
    
    // Create a method and add it
    set method = ##class(%MethodDefinition).%New("MyClass.MyMethod")
    set method.ReturnType = "%Integer"
    set method.FormalSpec = "x:%Integer,y:%Integer=10"
    set method.Description = "Return product of x and y"
    set method.CodeMode = "code"
    set method.Code = " new result"_$c(13,10)_" set result=x*y"_$c(13,10)_" quit result"
    set sc2 = class.Methods.Insert(method)
    do:$$$ISERR(sc2) $system.Status.DisplayError(sc2)
    set sc = $$$ADDSC(sc, sc2)
    
    // Save the class definition
    set sc3 = class.%Save()
    do:$$$ISERR(sc3) $system.Status.DisplayError(sc3)
    set sc = $$$ADDSC(sc, sc3)
    
    return sc
}

Hi all.

I want to insert my dataframe into InterSystems IRIS. So, I tried to do this:

df = spark.read.load("/home/imported-openssh-key/zeppelin-0.8.0-bin-all/bin/resultData3/DF.json", format="json")
df.write.format("com.intersystems.spark").\
option("url", "IRIS://localhost:51773/DEDUPL").\
option("user", "********").option("password", "********").\
option("dbtable", "try.test1").save()

And got this error:

Purge Task History manually

Hi,

I've read into console.log that there is some problems writing the global Task History

This is a FYI for anyone who has experienced the following error after upgrading an existing instance to any product based on Caché 2017.2.2. In our case, the products are HealthShare HealthConnect for Redhat x64 and for Windows x86-64 but I believe it would be a common problem for any InterSystems product on any platform, if based on Caché 2017.2.2. After upgrading our development instance from 2016.2.2 to 2017.2.2, we experienced the following errors when attempting to start a pre-existing Java Object Gateway that was defined prior to the upgrade:

I faced with the issue when WebSocket connection just fails without any errors if I send data with size 384 bytes and more (In binary mode the same). As I know by standard WebSockets frame does not have such limitation. Is there any way how to decrease it? This limitation too small, it is too difficult to fit this size and needs to send data much more often than I expected. Tested with Caché 2016.2, 2017.2 and IRIS 2018.1.

Hi community,

I've created a BS that uses FTP InboundAdapter. It works, read the file and process it.

The problem is when there not any file in the FTP folder, it raises the following error:

ERROR <Ens>ErrFTPListFailed: FTP: error en List para *.csv (mensaje='No-transfer-time exceeded. Closing control connection.',código=421)

I think it is something about the configuration, but I don't find what is the problem.

To deploy a DeepSee solution, the docs recommend that you define a namespace on the reporting (mirror) server, and "define mappings to access the application data, application code, DeepSee cube definitions, and DeepSee data on this server". (http://docs.intersystems.com/ens20152/csp/docbook/DocBook.UI.Page.cls?KEY=D2IMP_ch_overview#D2IMP_overview_architecture)

We have a new requirement being push down by our Data Security to no longer use Local SQL Accounts to access our Databases. So they asked me to create a Service Account that is on the Domain for our connections to each database.

I tried just changing my JDBC connection to using this Service Account and Password but I am not having any luck trying to connect to the database.

" Connection failed.
Login failed for user 'osumc\CPD.Intr.Service'. ClientConnectionId:ade97239-c1c8-4ed1-8230-d274edb2e731 "
