Hi, 

I'm working on my first SQL service using the SQL inbound adaptor, and I'm having trouble. 

I've been following the documentation but it errors on  set req=##class(ESQL.request).%New()

Would anyone be kind enough to share a working example?

Kind regards, 

Stephen

Class ESQL.NewService1 Extends Ens.BusinessService 
{

Parameter ADAPTER = "EnsLib.SQL.InboundAdapter";

Method OnProcessInput(pInput As EnsLib.SQL.Snapshot,
   pOutput As %RegisteredObject) As %Status
{

 set req=##class(ESQL.request).%New()
 set req.CustomerID=pInput.Get("CustomerID")
 set req.SSN=pInput.

I've been looking at the idea of developing a Time Travel Debugger utility.

It would take a debug target and have a few options such as stack depth and disclude system code.

The debugger would either be started from an external tool, or triggered from a line of code inserted into a method that I want to record.

The debugger would execute the code from start to end and record the full stack on each step to the configured depth.

A visualisation tool would provide a set of controls to play the recording forwards and backwards and provide various ways to search and jump to points in the recording.

I want to test automatically that HL7 business operation works correctly in error conditions. One is to test CE acknowledgement. I have planned to implement test production which includes business services for different situations (AA, AE, CA, CE, timeout, late response etc).

How should I implement HL7 business service that always returns CE (commit error)? I have tried but it keeps returning "AA".

In Persistent class, a data global is created which holds the data similar to the table created . Through terminal we can add more records to this table according to the structure of the table. How are the records reflected back into the table which has been set at global . In other words How are the global mapped to the SQL table?

This article was written as an attempt to share the experience of installing the InterSystems Caché DBMS for production environment. We all know that the development configuration of a DBMS is very different from real-life conditions. As a rule, development is carried out in “hothouse conditions” with a bare minimum of security measures, but when we publish our project online, we must ensure its reliable and uninterrupted operation in a very aggressive environment.

Hi,

The fault message definition is missing from my service WSDL. I would like to add these bold styled text to my WSDL. How can I do that? The aim is when I get  the WSDL of MyService with ?wsdl URL the response contains the bold styled text.

Hi,

We are using Cache 5.0,  we use Cache telnet and Other emulator (using telnet connection) to launch the applications.

Is there a way to identify the  type of device is used?.  Based on the emulator  I can few custom changes to be applied.

Thanks and Regards,

Hi,

I want to test the node.js interface to iris with trial sandbox. The node.js documentation refers to get de node package from the instance bin directory. As I'm trying to use the trial sandbox I don't have access to the directory. Please let me know where I could download iris.node package.

Thanks,

Hello,

I'm looking to find if there is a datatype convert equivalent in Object Script to SQL convert function. Have a VarBinary string coming in from source application (which is really performing a SQL dump). The source application uses the standard SQL convert function to convert from varchar to varbinary on their side.

I know &sql(Convert()) should work in Object Script, but am wondering if there is a better way of doing this. 

Getting data in via flat file (Record Map), then using data transform to transpose this data to SDA3.

Hi Community!

We try a new approach to the InterSystems Developers YouTube Videos called "Coding Talks"!

Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.

Check this video I made by myself participating in Advent of Code 2018 and coding with InterSystems ObjectScript in VSCode.

Coding Advent of Code 2018 Using InterSystems ObjectScript 

I have a simple callout library:

#define ZF_DLL
#include 
#include 
#undef ERROR

int GetRandom(double* random) {
   // Py_Initialize();
   // Py_Finalize();
   *random = 1.0;
   return ZF_SUCCESS;
}

int main(int argc, char **argv)
{
   printf("Random: ");
   double random=0;
   GetRandom(&random);
   printf("%lf", random);
   return 0;
}

ZFBEGIN
    ZFENTRY("GetRandom","D",GetRandom)
ZFEND

I compile this code as a shared library and it works fine with:

set path = "library.dll"
write $ZF(-3, path, "GetRandom")

It also compiles and works as an executable.

Hello.

I have a delimited flat file that I need to read and then generate an HL7 A08 message from the fields in the file.  I used the Management Portal's Record Mapper to generate the Map.Record class, then used drag & drop to map fields in the delimited flat-file to an A08 message.

But when I try testing this in the test tool, I'm getting an ERROR #6254: Tag expected . XML input. ... is not in proper format as child of Record (ending at line 2 character 11).

I can't find any real information on the error other than a mention that 6254 is an error :-)

Suggestions,

Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

zn ""
do ^%SYS.

Hello All,

Hoping someone can help with this odd error.

A vbscript file is being used to perform an update to cache.

The file has worked without an issue for well over a year.

Recently, the update has begun to throw an error.

(class references modified to remove client data)

UPDATE CACHE.UCI.Reg.Pat (Column1) VALUES ('USERNAME') WHERE ID = '2190284'

C:\Web\Config\SchedTasks\script1.VBS(73, 6)

Microsoft OLE DB Provider for ODBC Drivers: [Cache ODBC][State : S1000][Native Code 105]

[c:\Windows\SysWOW64\cscript.

A very simple SQL

SELECT field1 F1, count(field2) CntF2
FROM GCT.PA_Data
where field1 is not null
group by field1

gives an error back:

 [SQLCODE: <-461>:<Communication link failure>]

  [%msg: <Connection 'TRAKCARELIVE': Execute: SQLState: (HY000) NativeError: [10053] Message: [Cache ODBC][State : HY000][Native Code 10053] [c:\intersystems\ensemble\bin\cache.exe] Software caused connection abort> ]

It does work in another (test) environment, but not on live. Any idea why?

As a result of Evgeny's recent questions regarding the use of QEWD.js with IRIS in another post, I thought it would be a good idea to create a separate post focusing specifically on how to use QEWD.js to create REST APIs for IRIS.

QEWD.js is,  of course, a Node.js framework, and all the REST API code can be written entirely in JavaScript. 

The RealWorld Conduit reference application makes a great exemplar for this kind of thing, as the APIs are all published and there are numerous implementations of both front-ends and back-ends for it, using different technologies, frameworks and databases.

Is their a way to queue messages in a business operation to be processed later? I want to process messages over a certain size on a schedule, but let everything else process in real time. Is their a way to do this with one business operation or would I have to queue the large messages in a different business operation?

what is mirroring??

Hi Everyone!

New session recording from Global Summit 2018 is already on InterSystems Developers YouTube Channel:

Advanced Cloud Provisioning & Deployment

Dear all,

In our application made in Caché object script, when we deploy some classes modified we have the option of calling "Purge queries" feature of Caché.

We only were doing this call when a %Persistent class definition (table) was modified, as we assume that no other changes affect the cached queries and we don't  want to purge them by default, as the first run of a query becomes slow.

We had a case where no table definition was changed but a purge queries was the solution.

Do you know if any other change could affect the cached queries and a purge queries is necessary? 

Regards,

After enabling archiving log functions, Oracle can get real-time change data through CDC.

Can Cache database realize such functions?

My requirement is to take incremental data from the cache database regularly every day and synchronize it to other relational databases.

Incremental data can be text files.

Hello,

I'm trying to use Websockets and understand how it works. To do so, I tried to follow the sample in here :

https://github.com/intersystems-ru/WebSocketsSample

I opened studio, connected to my server into the USER namespace and use the Tools -> Import Local in order to add the 3 files (app.js.xml, index.html.xml and WebSockets.Main.cls )

I compile without error and use the View -> Web Page and it doesn't work as expected 

I can't see here what's the issue. Does anyone have some ideas ?

Thank you very much.

Hi, I updated the schema on our live node, but the change did not occur on the mirror server. Is there some setting that I need to enable? Everything else seems to be updating but the schema has not

Can you advice on what I could be missing or is this something that is known?

Hello experts, 

I am new to IRIS and I was told I could get a great hands-on experince with the commuity edition that is currently availabe on mutliple cloud providers.

Unfortunately connecting Atelier to the given IRIS instance has been unsuccessful: 

Accorording to this troubleshooting guide: 

- A single-user license is not sufficient to run Atelier.

According to my License Key: 

   License Type=Single Concurrent User

And my license use is at 100%: 

How am I supposed to connect and test IRIS if the Communty Edition does not provide a suffiscient license? 

Am I missinng somehitng else?

Thanks,

Evgeni
