Atelier: Getting Connected

I just installed Atelier, but when I tried to start it, I got the error "Java was started but returned exit code = 13". What's the issue here? How can I fix it?

Please see the screenshot below:-

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.

Example:

(for example globals: ^data1, ^data2, ^data3 are critical area)

Should I use somehow function $LOCK() or there is another way how this can be done?

An installation or upgrade of Caché, Ensemble, or HealthShare on Windows could fail with the titled error if a newer version of the Microsoft Visual C++ Redistributable 2013 (x86) or (x64) is installed instead of version 12.0.30501.

If you encounter this error during an installation, you can get around it by uninstalling those versions of the redistributables in the Control Panel, then manually installing both x86 and x64 older versions directly from this link This problem has been corrected in maintenance kits 2016.1.4 and 2016.2.2 and all released 2017 versions by devchange ALE2949.

Hello Greetings-

I am exploring on converting HL7 to FHIR.

1. I saw there are built in DTLs “FHIR.FromSDA” and “FHIR.ToSDA” to convert SDA -> FHIR and FHIR -> SDA. Similarly Do Intersystems have DTLs for HL7 -> FHIR and FHIR -> HL7?

2. The reason why I am asking is, I see in HSLIB namespace HS->GateWay->HL7->HL7toSDA3 and HS->GateWay->SDA3->SDA3toHL7 DTLs. Like-wise I am trying to locate HL7 -> FHIR and FHIR -> HL7. Please help me to locate them

3. If there are no built-in DTLs for converting HL7 -> FHIR and FHIR -> HL7, what is the process to achieve this?

Thanks much in-advance.

Thanks,

Surya

How to we count no.of nodes in global.

There is method:

$System.OBJ.New( ClassName As  %String = "" )

If class with name ClassName exists - everything is OK.

But, when class does not exist, there is error - <CLASS DOES NOT EXIST>

How can I check before calling $System.OBJ.New() if class witn name ClassName exists?

I am currently working on a issue with WRC on one of my Inbound SQL Adapters not returning all the records it should be. If I looked at the count of the records in Ensemble and compare it to that of a Microsoft SQL View, Ensemble seems to be off by a few records here and there. I am using a full dynamic select statement in my settings of the adapter.

Greetings!

I'm new to Zen reports and I'm wondering if what I'm trying to do is possible.  I have a classmethod  that accepts three parameters to generate an xml file from a global.    I've set up my Report Definition to call the ClassMethod that generates the .xml file; however, I'm trying to figure out how to pass the parameters to that ClassMethod from the Report Definition.  The example in the documentation shows parameter passing using SQL (which I'm not using), so I'm curious if this will work.  

I'm trying to create asynchronous Ensemble service/operation pair for SOAP passthrough.

General configuration:

• Ensemble Service receives a message and immediately returns an answer to a caller (message received or some error)
• Ensemble Service asynchronously calls Business Operation
• Business Operation  does guaranteed message delivery, etc.

Is it a viable approach?

Any tips? Ideas? Caveats? Code?

Seems like I can sublass EnsLib.SOAP.GenericService and change Sync to ASync (and provide a default reply immediately).

I'm getting this error a lot in Atelier.  These are not extremely large files, and I can't seem to find a magic line count or byte size that triggers the issue to occur.

I'm using the latest (I believe) version 1.0.262. Is there a setting that allows larger files to be parsed successfully within the editor?

Hi Guys,

We need to print html reports, in the server side, to a specific printer that is installed on the Cache Server , and using the Internet explorer that is installed on the Cache Server to do that .

Hi!

While i am trying to write a data i am getting a error as "<PROPERTY DOES NOT EXIST>zFile+15^User.zKQRest.1 *value,%Collection.ListOfObj" but there are values stored in it. How can i break it write it separately.

Hello everyone .

I am trying to update a setting of an operation directly via the code of a business operation.
Concretely, my customer want a counter for the number of calls to the operation and the possibility to redefine the point of this counter.

Hi,

I am new to Cache' MV but have extensive experience with other Pick flavors especially Unidata. 

I need to determine the impact of adding several indexes to a large file with over 51,000,000 records. 

On other systems, I could use FILE.STAT, ANALYZE.FILE and shell to the OS to determine how large the index file was. 

None of those seem to be available in Cache' MV. Shelling to the OS just tells me the size of CACHE.DAT.

What is the best way to determine what the disk impact would be if I added an index (CREATE-INDEX) to a file?

TIA,

Steve

Hello,

I have a DB server (ser-app-db) where cache is installed as server.

I have a Web server (ser-app-w) where cache is installed as web server and configured as CSP gateway.

I followed the configuration guide (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KE…) and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/csp/samples/docserver/request(GET): work and show the request

http://ser-app-w/csp/samples/docserver/request(GET): return a 404.

Hi

1. Is it possible do define an index like that :

create index UIX on MyTable (Column1) where Column1 is not null

2. What happens if we add an index on a property that is NOT required, meanning that not all records will be indexed because we do not allow null subscripts ?

Good day,

I need to find out if it is possible somehow to receive actual linux TIMESTAMP for example with $NOW() or other functions.
I was trying to recalculate it with $NOW() function, but without success. I would like to simulate Redis TIME command in COS.

My tryings:

USER > set time = $NOW()

USER > w (($PIECE(time,",",1)*86399) + $PIECE(time,",",2))
5573319043.403186

But in Redis it is:

> time
​1) 1502471158

On web page: http://try.redis.io/
type "time" + enter. And it will results as short documentation says: https://redis.io/commands/time

And this behavior I would like to implement in COS.

I have a list of %Library.ArrayOfObjects . Each of list elements has some properties. I have to sort list by one of its objects properties. Is there a predefined method to doing that? (quicksort maybe?)

I have a tablePane. TablePane can have one, or two, or three parameters. It depends on some conditions.

At first I add all three parameters to tablePane.

set p1 = ##class(%ZEN.Auxiliary.parameter).%New()
set p1 .id = ..id1
do table.parameters.Insert(p1 )
do %page.%AddComponent(p1 )

set p2 = ##class(%ZEN.Auxiliary.parameter).%New()
set p2 .id = ..id2
do table.parameters.Insert(p2 )
do %page.%AddComponent(p2 )

set p3 = ##class(%ZEN.Auxiliary.parameter).%New()
set p3 .id = ..id3
do table.parameters.Insert(p3 )
do %page.%AddComponent(p3 )

Then through javascript I set parameters values and query

When I open a BPL in Atelier and right click 'Open diagram editor' I get a Java Incompatible browser error message (see below).

I'm using Windows 8.1, Atelier 1.0.190 and IE 11.

All the M.S. updates are up to date.

I also have firefox and chrome installed.

Trying to change default browsers etc. did not work.

I understand this is a rather broad topic (and at times involves religious sentiments) yet I would like to look at it from the Caché perspective:

• Do you use an issue tracking / collaboration system? If so which one. Any you would recommend or immediately dismiss based on personal experience?
• How do you keep track of large code bases? Thousdands of folders named backup1, backups2, ..., SVN, git?
• Do you have a development server to which you commit and test features there, or do you rather run a local copy of caché and implement features locally first, then push to the

Hi, I am trying to understand the transformational methods.

• LogicalToDisplay()
• LogicalToOdbc()
• OdbcToLogical()
• DisplayToDisplay()

I have created a small class with the only property of List as %List, see below.

Class LastName.Demo2 Extends %Persistent
{
Property List As %List;

}
Then I entered the following commands in the Terminal

Set Oref=##class(LastName.Demo2).%New()

FOR I=1:1:5 S $LI(List,I)="Value="_I

Set Oref.List=List

WRITE Oref.ListLogicalToDisplay(Oref.List)

^

<METHOD DOES NOT EXIST> *ListLogicalToDisplay,LastName.Demo2

zw Oref

Oref=<OBJECT REFERENCE>[2@LastName.

The data type %Char or %Library.Char

The description says it is a fixed length character field.

How do I set the fixed length?

Or by just setting %Char to something, does that automatically define its length?

Are the parameters MINLEN, MAXLEN involved? Or are these the way I set the fixed length?

Any help with this?

In a previous exercise, I was able to show the power of Caché.
A medium-designed set of interdependent tables with some GB of data.
URLs cross reference over some million pages resulting in ~3 billion records

Competition was between

• Caché
• PostgreSQL
• MySQL

Criteria were Speed + Storage consumption
I composed  a customized loader fed over a "raw" TCP connection
Mapping the "objects" into the final table by directly writing to Global Storage.

Hi,

I use cache 5.0 and access cache through OpenVMS.

The disk-space under a particular namespace has grown up in size due to cache.dat. How to recreate cache.dat to bring up more space back on disk?

Hi Everybody

Question , I need to define a user that will be limited to only to one namespace.

I defined the start up namespace in the user's definition , but it doesn't limit the user.

Any advice would be appreciated.

Thank you Simcha

While using custom business service i'm not getting the Acknowledgement . But i tried with standard business service im getting acknowledgement . can you please help me to figure out the issue. Thanks in advance!!!

Hi, Community!

I'm pleased to announce that we deployed a new release of Developer Community.

This release comes with improved Search.

The updated search feature introduces full-text scan, auto complete for the key words, filters on articles, questions, comments, members and works faster.

Here is the small video on how it works.

Also, we fixed a few bugs and made DC faster.

Hope you like it! 

Stay tuned for the next release and introduce your issues here in comments or and enhancement requests and other issues in the DC Feedback group!

Hi, folks!

There is an interesting discussion in the neighboring topic which raises a question for me: is there any reason to have %Status as a return value for COS method?
