#Caché

Hello,

I want to search a process ID in Object Script using the reference variable e.g. 1119102928 and kill that process ID. Please guide how it can be achieved.

Thanks in advance.

I' have done some tests with Caché and Apache Zeppelin. I want to share my experince to use both systems together. I'll try to describe all steps that are required to config Zeppelin to connect to Caché.
 

What is  Apache Zeppelin?

For all who think: What the heck is Apache Zeppelin?, here some details what the project site (http://zeppelin.apache.org) says:

"A web-based notebook that enables interactive data analytics. You can make beautiful data-driven, interactive and collaborative documents with SQL, Scala and more.

Has anyone worked with OPC Unified Architecture protocol (iot/machine to machine communication protocol for industrial automation)?
If so, how did you communicate with it?

In the previous parts (1, 2) we talked about globals as trees. In this article, we will look at them as sparse arrays.

A sparse array - is a type of array where most values assume an identical value.

In practice, you will often see sparse arrays so huge that there is no point in occupying memory with identical elements. Therefore, it makes sense to organize sparse arrays in such a way that memory is not wasted on storing duplicate values.

In some programming languages, sparse arrays are part of the language - for example, in J, MATLAB. In other languages, there are special libraries that let you use them. For C++, those would be Eigen and the like.

Globals are good candidates for implementing sparse arrays for the following reasons:

Hi everybody

I'm new in this forum and also new working with a Caché-Database.

Problem:
I have to delete records from a table (by SQL) which contains a field declared as:
Property Image As %Stream.FileBinary;

When I try to delete a record with an image I get an error
[%msg: <FEHLER #5019: Kann Datei 'H:\BK Solution\DSTBern\eXpert\Data\Expert\stream\YJC7o7ngR9WUeA.stream' nicht löschen>]
[SQLCODE: <-412>:<Allgemeiner Stream-Fehler >] 

because the physical file doesn't exist (for any reason) but the database want's to delete this file.

Hi everyone,

Im new  in cache, i came from Java and im missing some features that i couldn't find in the documentation,  I hope you can help me with this questions.

Just a brief introducction: 

- Im in a project with old cache version, so saddly i can't use Eclipse + Atelier, so im using Studio.

- Currently im in a project with persistent classes, we want to turn apart the globals and focus on tables. 

The questions:

Is there any way to make something like hibernate for cache %Persistent classes?

Hi,

recentley we started to work with Atelier & VSTS in our organization .

we are looking for a way to use the VSTS as Our Version/Source control system .

I have read the article about "Continuous Delivery of your InterSystems solution using GitLab" & now trying to find a way to use a similar metodology with the VSTS that we have in our organization.

It Apeares that it is possible to Create a Git Repository in the VSTS but i'm not sure how are we to use it from the atelier.

The main questions are:

1. What Is the best practice in saving cache code in VSTS GIT?(cls files?, legacy XML?

In our table, we have a column cities,  which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String =  "CA"

Our filter should run this query to show all cities of state ca

"SELECT Name FROM City WHERE State= "_%page.State

<column colName="City"
filterQuery="SELECT Name FROM City WHERE State= <This is where I am stuck>"
filterType="query"
header="City" 
width="10%">
</column>

I am not able to pass any parameter to filterQuery. 

I have a class defined like this:

Class test.ABC Extends %RegisteredObject   {

Property myProp As %Binary [ Internal, Private ];

}

Is there a way to get a value of myProp from outside of the object?

I can't modify or extend the class obviously.

Need a sample of  using %Net.HttpRequest and %NetHttpResponse  from Cache to retrieve and then use/reuse a bearer token to send json data to a REST web service.

Hello,

Need some technique to solve an issue about zen page table.

- "xyz" table exists in all my namespaces.

I have a simple Zen page  in "USER 1" namespace. It has a tablepane which pulls data from "xyz" table.

OnLoad of the page i want the  zenpage to pull the data from "USER 2" namespace with same "xyz" table name.

Zenpage has to be in  "USER 1" namespace

I tried to use the server side callback handler %OnAfterCreatePage()  and do a ZNSPACE "USER 2" but still it is not doing the job of pulling data from another namespace.

Any suggestions will be appreciated.

Thanks,

Jimmy Christian.

here is my trigger:

Hello,

I'm trying to get ODBC running on a Mac but I don't get it working.

Has someone an overview how te install,configure and use it in Excel on MacOSX ?

Second, my issue:

I believe my current villain is “incremental compiling.” I was able to compare early compile output with later compile output:

Hi

I am working with a Caché system with a Python binding and big datasets in health care. I am using the Python library Pandas and Jupyter notebook for data manipulation and often special modules for different projects, including different versions of Python. To keep the environments separated, I have been testing Docker, but I am at loss on how to install the Python binding. Has anyone any experience with this? Or better yet, a Docker image that has the binding installed?

I am also considering that Docker might not be the suitable for this situation and I am grateful for any thoughts on this.

Have some free text fields in your application that you wish you could search efficiently?  Tried using some methods before but found out that they just cannot match the performance needs of your customers?  Do I have one weird trick that will solve all your problems?  Don’t you already know!?  All I do is bring great solutions to your performance pitfalls!

As usual, if you want the TL;DR (too long; didn’t read) version, skip to the end.  Just know you are hurting my feelings.

Hi! I've been fiddling with linked tables to get data from other servers, and I encountered a problem that I'm curious about. Maybe I'm not using these tools as intended or there's more going on, so I'm asking here.

I'm running a query on linked table A, something simple like this:

select name from A where id = 5983658923646

And I get this error:

[SQLCODE: <-400>:<Fatal error occurred>]

  [%msg: <>]

If id, or anything comparison, is something smaller like 4345, it works just fine. It's only when the where reaches a certain length, not just id, that it fails.

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns. 

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:

Class Test.

Cache version: Cache for Windows (x86-64) 2017.2.1 (Build 801_3U)

Good Afternoon,
I have a co-worker who is trying to run the below query via ODBC. The issue is that the query appears to be running extremely slow (nearly 2 hours).

Unix:  I'm trying to switch to using the $ZF(-100 function in place of $ZF(-1.   I have it working for a simple, single, cmd, but can't figure out how to pass a piped sequence.  Maybe this just isn't allowed?

For example:

S sc=$ZF(-1,"ps -Af | grep username")

works, but I can't figure out how to format this for the $ZF(-100 function.

???

Thanks

Hello,

We're having troubles with working over Telnet on Caché Unicode with WRQ Reflection.

We can't input extended characters (é,à,Ø,...), DELETE-key doesn't work, ...

Has anyone a solution for working with WRQ Reflection or a decent alternative ?

We tried Putty and Caché-terminal but these are not sufficent.

Regards,

Kurt Hofman.

So i'm having this problem with the task manager, the tasks simply stopped running. I had a problem with queued massages and trying to figure out what to do i'm afraid I may messed up something else, can someone help me ?

Hello,

I have a very simple web service that I'd like to secure via SAML Authorization with X.509 Certificates. I am, however struggling with documentation and my lack of cryptographic skills. (I do this just for educational purposes now, but need to use it in the future)

Does anyone have an example that shows how to construct a SOAP Client with adding all necessary security headers manually or point me to a decent learning resource?

Thank you very much!

Hello All!

I'm brand new to HealthShare and trying to enable LDAP Authentication. When I run the authentication test, the base DN looks good and the search user is successfully authenticated. However, the user is still not found. We have a linux installation in Azure, and I'm connecting to a Windows AD server (provided both Azure and local hostnames). I'm using the full DN in the username field. For the "LDAP Unique search attribute" I've tried, CN, DN, and sAMAccountName.

Thanks for all replies in advance.  We have a security vulnerability that we have to get rid of.  We use Putty software to connect to cache as a terminal allowing several users to do maintenance work in cache.  this uses telnet Plain text.  I know that we can configure telnet to be encrypted using the super server service and I'm looking for software that can work like Putty as a terminal using encryption compatible with cache telnet encryption.

Hi There

I created function to manage string as requirement  extract the first two letter of each word after space for example:

Text = "Review symptoms to report with patient"

After passed function it will be return "Resytorewipa"

ChangeFormat(desc)

   set desc = "Review symptoms to report with patient"
   q:$g(desc)=""
   SET delim=" "
   SET countdown=$LENGTH(desc,delim)
   set i =1
   for
    {
        q:i>countdown
         set abbrv = $e($PIECE(desc,delim,i),1,2)   // But if I put w abbrv  I can get "Resytorewipa"
         set i = i+1     
    }
   w abbrv

However, at the end I got only  abbrv=''pa"  how to get data as requirement.

I am still new to cache objectscript and am trying to figure out how I would go about removing the escape characters from my JSON below. When I call the $toJSON method it's adding the "\" character in the file path.

{"FileStatus":"P","Path":"\/somepath\/test\/test123\/filename.txt","InterchangeOID":"100458"}

My Code:

set tJSONFile = {"FileStatus":pRequest.FileStatus,"Path":pRequest.Path,"InterchangeOID":pRequest.InterchangeOID}

set tJSONFile = tJSONFile.$toJSON()

Thanks.

I have a process that takes data from a CSV file (actually a record mapper object) and creates a nicely formatted JSON string I would love to send this along to a RESTful business operation.  However no matter what I try, I continually get <INVALID OREF> errors when trying to populate the object that extends Ens.Request to give it the JSON string.

I can add strings, other objects, you name it - but stuffing a JSON formatted variable/object into another object I want to send someplace is proving to be an impossibility.

Does anyone have an example of sending an Ens.

I need to read the sourceClass attribute of the transform node in the Xdata block of a dtl.

given:

Class EXC.DTL.Lamont Extends Ens.DataTransformDTL [ DependsOn = (Sam.msg.lamont, Sam.lamontNext) ]
{
Parameter IGNOREMISSINGSOURCE = 1;
Parameter REPORTERRORS = 1;
Parameter TREATEMPTYREPEATINGFIELDASNULL = 0;

XData DTL [ XMLNamespace = "http://www.intersystems.com/dtl" ]
{
<transform sourceClass='Sam.msg.lamont'  targetClass='Sam.RM.lamontNext' create='new' language='objectscript' >
<annotation>Sample transformationannotation>
<code>

I need to return the value 'Sam.msg.lamont'  for the DTL.

I'm using callin to get global values.

Here's a simple function to get string value from global and return it:

int GetGlobalStr(char *global, CACHE_EXSTRP result)
{
    int push = CACHEPUSHGLOBAL(strlen(global), global);

    // narg Number of subscript expressions pushed onto the argument stack.
    int narg = 0;

    // flag - Indicates behavior when global reference is undefined:
    // 0 — returns CACHE_ERUNDEF
    // 1 — returns CACHE_SUCCESS but the return value is an empty string.
