#Caché

I am trying to pinpoint and troubleshoot an issue we have been seeing lately. We have several SQL Outbound Adapter Operations that are seeing issues trying to connect to our MS SQL Servers using the JDBC Gateway for calling insert, select, update, and stored procedure calls.

ERROR <Ens>ErrFailureTimeout: FailureTimeout of 20 seconds exceeded in osuwmc.Visit.

InterSystems FAQ rubric

You can programmatically retrieve routine dates and sizes using the RoutineList query of the %Library.Routine (or just %Routine) class.

The RoutineList query has an argument, and the routine name to be searched can be specified by prefix match or middle match. (For wildcards, specify * or ?)

In the example below, *.MAC is specified as an argument.

 SET tStatement =  ##class(%SQL.Statement).%New()
 DO tStatement.%PrepareClassQuery("%Routine" , "RoutineList") 
 SET rs = tStatement.%Execute("*.MAC",,0) 
 DO rs.

Introduction

Say you have a receiving system that accepts HL7 and provides error messages in field ERR:3.9 in the ACK it returns. You require a different reply code action depending on the error message, however the Reply Code Actions settings for the operation do not provide this level of granularity. One option could be to create a process that takes the ACK and then completes the action you were expecting, however things can get a bit messy if the action is to retry the message, especially when trying to view a message trace.

If you are seeing this error during import: ERROR #6301 Line: 2 Offset: 118 This does not appear to be a Cache exported file, unable to import.

This error is caused by exporting from InterSystems IRIS and trying to import into Caché. If you plan on exporting from IRIS to Caché, you can use the following qualifier to export your classes so that Caché does not throw an error on import:

w $SYSTEM.OBJ.Export(<items>,<filename>,"/exportversion=cache2018.1")

Please see the Documentation for more information about this Export Qualifier

InterSystems is committed to providing high quality product support to customers for all products, new and old.   As products age – Caché is now 25 – that support will evolve.

InterSystems IRIS was released in 2018 and it is the successor to Caché and Ensemble.  Many Caché/Ensemble customers have migrated to IRIS or have plans to do so in the next few years.  Customers continuing to use Caché or Ensemble should be aware of the following important announcement:

Caché/Ensemble maintenance releases will continue for the next 4 years - through Q1 of 2027.

Hi Community,

I am trying to save data into SQL table but each entry  getting saved twice in the SQL table. Is there any reason data is saving Twice in the SQL table 

I have created a %Persistent class for the fields

Please find the business operation below

Class Patient.DBOperation Extends Ens.BusinessOperation

{

Parameter ADAPTER = "EnsLib.SQL.OutboundAdapter";

Property Adapter As EnsLib.SQL.OutboundAdapter;

Parameter INVOCATION = "Queue";

Method OnMessage(pInput As Patient.PatientDBReq, pOutput As Ens.Response) As %Status
{
    Set Entry=##class(Patient.PatientDBReq).%New()
    Set Entry.

1.Background

        1.1 I met a few project that their interface servers were crashed. Cutoms wanted resume server as fast as we can. their servers are running at lan,and they can't use git,there are some namesapce in the server running different service,and usualy there is only one server.

        1.2 In the message,it has property in typeof characterstream,as you know,the message search page doesn't support filtering with  property of characterstream,so it's so hard to find the messge you want.

        1.3 Other workmate may update the code on the server,and mybe their is something wrong.

The task of handling office documents, namely docx documents, xlsx tables and pptx presentations is quite complicated. This article offers a way to parse, create and edit documents using only XSLT and ZIP.

Why? docx is the most popular document format, so the ability to generate and parse this format would always can be useful. The solution in a form of a ready-made library, can be problematic for several reasons:

• library may not exist
• you do not need another black box in your project
• library restrictions : platforms, features, etc.
• licensing
• processing speed

In this article, I would use only basic tools for work with the docx documents.

Thanks to @Dmitry Maslennikov I have access to a Container for Caché.
It is based on Centos.
Is there anywhere a container based on Ubuntu available?

One of the reasons why I love Cache and Iris is that not only you can do anything you can imagine, also you can do it in a lot of different ways!!.

Imagine that you have an integration running with IRIS connected by ODBC you probably only run SQL queries but you can also create stored procedures and inside write the code to do everything you can imagine.

I'm going to give you some examples but the limit is your imagination!!

You might wonder, wait! I don't know how to create a store procedure in IRIS.

Goodday,

I would like to Validate token signature with public key i have in pem format, i am using below  code but i get error message. Could you please tell me what i am doing not right? FOUT #5002: Caché fout : <DIRECTORY>zLinkToFile+2^%Stream.FileBinary.1 *-----BEGIN PUBLIC KEY-----

{
   
     Set tFile=##Class(%File).%New("c:\Kety\publicKey.pem")
    Do tFile.Close()
    Set tStatus=tFile.Open("RU")
    $$$ThrowOnError(tStatus)
    Set tPublicKey=tFile.Read()

I know this problem something to do with sort and collation and string comparison vs numeric only strings, but I can't fathom out the details of it. 

I have the following global, where all values are suffixed with a space, I believe the intention is to prevent empty strings and force string comparisons rather than numeric. Which is fine when searching for an exact match, so searching for "ABC" internally looks for "ABC ", or "800999" looks for "800999 ". However one function tries to search for strings containing, (specifically beginning with), a partial code.

Hey guys.

I'm having trouble using the Certificate in my BO.
It started to occur after updating the certificate.

I have 2 configurations and 2 certificates, the first one was updated and no error occurs, the second one, the  bad certificate or Handshake failure errors occurs. Both have the same configuration.
I already tried marking SSLV3, handshake error occurs. When I unchecked it, a Bad Certificate error occurs.

Do you know what I can do in this case to solve it?I looked for some threads in the community, and I didn't find a solution for my case.

Hello, I am using the power bi report builder tool to create a report with dynamic parameters. Every time I try to create and apply a parameter in power bi query editor. I get the below listed error message. 

FYI: I have created a Data source connection using "InterSystems ODBC" Version 2015.01.00.429. I am getting data without any issue.

Hello everyone, i want to have an InterSystems Caché Installation cache-2017.2.2.865.0-win_x64.exe

Thanks

I need a copy of cache 2017.1x  as this is the last version supported by the VA on their network.
Any support here would be greatly appreciated. I have been a member of the M community since 1984.
Thanks in advance

I need a stored procedure where I can execute multiple delete from statements. 

This will work to create a stored procedure, but when I add in other delete from, get error invalid sql statements when try to create

CREATE PROCEDURE DeleteSpecimenTwo
  (IN Specno VARCHAR(50))
BEGIN
DELETE FROM PCONT WHERE PSPECNO = :Specno;
END;

This doesn't work

CREATE PROCEDURE DeleteSpecimenTwo
  (IN Specno VARCHAR(50))
BEGIN
DELETE FROM PCONT WHERE PSPECNO = :Specno;

DELETE FROM PSPEC WHERE PSPECNO = :Specno;
END;

Any suggestions

Thanks

Any ideas on why my %session.Data array would be wiped out after setting %response.Redirect in OnPreHTTP()?

Context: trying to implement a SSO patter for authorization code flow.  I mention this because it's all I can really pinpoint as to what's changing.  Typically a user logs in by providing their username/password and we validate in our database and set the %session.Data property with the user info.

I need connect to cache2016 database by python to get some data, but   I don' t know how to connect by python, did anyone know how to create connection？

If you can provide any python code, that will be better! 

Hi,
is there a way to know where IRIS or CACHE current instance is installed from objectscript?

Something like "iris list"

It will be easy to make a $ZF, iris qlist, and get the info, but i hope that there's something less complex than that.

Thanks

Hi,

Question about ZMIRROR routine.

I analyze a problem with the label NotifyBecomePrimary. It seems not performed after a switch.

After installing ZMIRROR routine in %SYS, is a restart required?
If It's required, It could be explain my problem.

Thank you.

The following code snippet uses GZIP to compress/decompress a file. Choose a file by specifying a file path in the "filename" variable.

Class objectscript.GZIP Extends %RegisteredObject
{
classmethod test() {
//Export Global(s) uncompressed
set filename="C:\Temp\myglobal.xml"
do $System.OBJ.Export("^oddEXTR.gbl",filename)
//Open exported Globals
set uncompressed = ##class(%FileBinaryStream).%New()
set uncompressed.Filename=filename
Set compressed = "C:\temp\mycomglobal.

Hello Everyone!

Following the example below i can download file only txt format, in other format(pdf,xls,rar) i have errors(can't open file), 

So, how i will change code for download file in other format? 

Thanks! 

ClassMethod GetFile(file) As %String
{
#dim %request As %CSP.Request
    set filename="E:\Rest\"_file   
    set %response.ContentType=..GetFileContentType($p(filename,".",*))
    do %response.SetHeader("Content-Disposition","attachment;filename="""_$p(filename,"\",*)_"""")
    Set %response.NoCharSetConvert=1
    Set %response.Expires=50
    set file=##class(%File).%New(filename)
    do file

The Art of Mapping Globals to Classes 1 of 3

Looking to breathe new life into an old MUMPS application?  Follow these steps to map your existing globals to classes and expose all that beautiful data to Objects and SQL.

By following the simple steps in this article and the next two you will be able to map all but the craziest globals to Caché classes.  For the crazy ones I will put up a zip file of different mappings I have collected over the years.  This is NOT for new data; if you don’t already have existing global please just use the default storage.

Over the years, I have found myself needing to create multiple HL7 messages based on a single inbound message. Usually these take the form of an order or result from a lab. Each time I have approached it, I have tried to start from scratch under the belief that the previous attempt could have been done better.

Recently, the need arose again and I was able to create a solution that I wasn't ashamed of. My main concern was that I would always either find myself getting buried in a BPL, or use ObjectScript and attempt to edit messages using the SetValueAt Method for the HL7 Message Class.

Hello,

Comming back to Cache after some long gap. Is it possible to use UUID  as primary key while creing a Persistant class (Not using the default numerical ID)?

and creating the relationships also using UUID?
