Does anyone send alerts via API / Web Services to an application such at Tivoli or CA Spectrum?  If so, can you share what commands you send?  e.g. If connection is down or queue depth > 200.   Thanks.

Hi guys,

How do you deal with underscore characters when using jsonProvider  and exporting or importing ?

for example:

USER>s jsonString="{""what"":""1"",""up"":""2"",""test_test"":""3""}"
 
USER>set status = ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(jsonString,,.outputObj)
 
USER>w outputObj.what
1
USER>w outputObj.up
2
USER>w outputObj.test_test
 
W outputObj.test_test
^
<UNDEFINED> *test

we found out that we can access it like this, but not sure if it's the recommended method-

w outputObj.%data("test_test")

I accidently clicked the mouse into the output window of studio (where you get the compile results etc) and typed soemthing in there (by mistake) and it came back with <SYNTAX>.

I've been playing with it further, and it's like a cut down version of terminal.

I can "s x=1" and the "w x" and sure enough, it will display "1" (ie the value of x)

when I call one of my utilities ie "d ^dev", my utility runs as expected, but when I try entering a value (my utility was waiting on a read *x) it generated a <SYNTAX> error.

In my previous posting about the new support in QEWD for JSON Web Token (JWT) support, I mentioned that it was a key step in enabling Micro-Service support in QEWD.  In this post I'll give some background to how they work and the thinking behind them.

If you haven't heard about Micro-Services and/or want to learn more, there's lots of information available if you do a Google Search.  Here's a good starting point:

Hello, I just noticed that the following query is not allowing when using cached queries.

The compiler will accuse the code about missing a closing quote.
Just so you know, if I use this query dynamically it works, so I guess it's related to the code linting.

Query T() As %SQLQuery [ SqlProc ]{SELECT TOP 3 JSON_OBJECT('lit':'Employee from','t':%TABLENAME,'name':Name,'num':SSN) FROM Sample.Employee}

The bold part is what is causing the error.

Hi, folks!

What could be the best backup/restore strategy for a small (less than 100MB) but very valuable database which is placed on AWS/DO virtual host?

1. Use AWS/DO backup/restore features?

2. External backup (as the most recommended)?

3. InterSystems backup?

4. Globals export to a zipped file?

5. cache.dat copy?

Looking for the most robust and easy to use/implement method of backup and restore in a way "setup and forget" (until it becomes needed :)

When I go through the Atelier Cheat Sheet on the connection configuration, it talks about an Eclipse master password and asks for two hints to remember the master password. However, it does not specify the master password. I can only assume the master password is the same as the Cache instance password.

Can anyone shed some light on this master password, where or how it is used, and any other useful information?

Hi

Is there anyway to catch info/warnings into an Ens.Alert when the inbound adapter is skipping  previously file (of any reason)?
Or any other way to pay attention to it.

In our log it usual have Warning or Info level and it stops there. We really want to create some kind of an alert when it happends.

All suggestions welcome

Sincerly,

Michael

I am beginner to ensemble and went through the introduction of ensemble in that they have mentioned three process of operations which is business service,business process, business operations is there  anyway to understand these process can anyone help me on this.

Thanks in advance. 

What is the Cache command to display the version of Cache?

To most of us it's almost dogmatic that $H can't be negative!

This is correct concerning the COS Special Variable $HOROLOG.
No doubt. It's the presentation of the actual date & time.
http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…

For dates before 1841 it's suggested to use Julian date before 1841.
Good for calculations.
But what about values in $H_format ?
Conversion functions $ZD(), $ZDT(), $ZDH(), $ZDTH() and  
for SQL  $system.SQL.TOCHAR() and $system.SQL.TODATE()
take  care of the conversion to human readable date. You know this.

tl;dr how can you tell if a number is really a string

The original question has been updated/improved.

Equality comparisons on floating point numbers will produce different results...

"1.1"=1.1  //is true!

"0.1"=0.1  //is not true :(

This second comparison can be fixed with...

+"0.1"=+0.1 // is true!

The problem is, what if we don't realise that a value is a stringy number, or just overlook implementing this defensive check.

One solution would be to lint check %Float properties and return types that should originate from a number and not a string, as discussed here...

I am trying to capture the write of a method to test the response in an unit test. I know everything works because one of my colleagues ran the code and did not froze on his machine.

I don't what is the cause of the freeze. I know that at line Use $io::("^"_$ZNAME) it stopes because i have put some write functions after every line in WriteCapture method and i only saw the first write function in terminal

I also used debug and in this case it didn't froze

PS: forgot to put the status in the XECUTE (vstrCommand, .

Greetings,

Is it possible to save Cache code into a file and then run it via command line?  

IE:  csession [ini] -U [ini] /path/cacheCodeFile.?

What I need to do is run a Cache script from the Linux command line.  The script will navigate data to produce a file and then it will exit back to the command line.

Thanks in advance for everyone's time.

I need to check if one class is a subclass of another (either direct or indirect).

For example:

Class Package.ClassA Extends %Library.Persistent
{
}

Class Package.ClassB Extends Package.ClassA 
{
}

Class Package.ClassC Extends Package.ClassB
{
}

In this example Package.ClassC is a subclass of 3 classes: %Library.Persistent, Package.ClassA, Package.ClassB.

So any of these checks should return 1:

Write ##class(Some.System.Class).IsSubclass("Package.ClassC", "%Library.Persistent")
Write ##class(Some.System.Class).IsSubclass("Package.ClassC", " Package.ClassA")
Write ##class(Some.System.

Hello, I've completed this tutorial: https://community.intersystems.com/post/deepsee-period-date-vs-same-per…
I've used the "year" level instead of a pivot variable.
I want to calculate something like the following variation: 100 * ([DateOfSale].[PTD] - [DateOfSale].[LYPTD]) / [DateOfSale].[LYPTD]
I create a new calculated member, under the same dimmension with the above expression.
I put the new calculated member under the Count measure and it tells me that "Two measures cannot be crossjoined"
What am I doing wrong?
Can you redirect me to some explanations and maybe a solution?
Thanks!

Hi, Community! 

Please find the Developer Community Video of the week on InterSystems Developers YouTube Channel:

System Sizing for Insanely Large Deployments

I need to get a list of all classes that are subclasses of two unrelated classes.

For example I want to get a list of all classes that are both:

• Persistent (extends %Library.Persistent)
• XML-Enabled (extends %XML.Adaptor)

To get subclasses of one class I can use this query:

set rs = ##class(%Dictionary.ClassDefinitionQuery).SubclassOfFunc("%Library.Persistent")

But what about two classes?

I suppose I can run this query twice, build two $lb, then iterate over one of them and build a new $lb with classes that appear in both lists. Are there any better approaches?

Is it possible to dynamically adjust the RetryInterval andFailureTimeout settings in a BPL?

I've got a business process that calls a web service operation to get a session ID from an external system.  There is a string property returned in the body of the response that indicate an exception occurred in the external system. I have code in the BPL that examines the property and sets the status property to an error status when that occurs.

Depending on what the value is I want to adjust the RetryInterval and FailureTimeout values used in by the system when the ReplyCodeActions is set to E=RD.

Hi!

I am not system admin. But it used to be very simple to install CSP Gateway on an apache system on Linux with Apache installed. I used to run the CSP Gateway installation program and after it was done, all I had to do was fine tune some configurations on CSP Gateway portal on http://<ip>/csp/bin/Systems/Module.cxw and I was up and running.

Good afternoon - 

I'm in the process of learning to make COS calls to REST-based web services and while I am having success, I'm struggling on how to parse out the results (I admit I'm very green at this):

Here's the code retrieving the JSON response:

w !,"Get the JSON"Set Result = {}.%FromJSON(Request.HttpResponse.Data)

This has Result as a Library.DynamicObject.

I can then write out the response using:

w !,Result.%ToJSON()

This works, I can see the response is valid and what I want.

I'm working on an existing Zen Report that uses queryClass/queryName to retrieve data using a class that has a Stored Procedure method. Which works fine.
I have created second class with a Stored Procedure method, I modified the zen report to use this class and now I'm having the following error.

Error: SQLCODE: -99 Message: User UnknownUser is not privileged for the operation
ErrorNo: 5540

Several Ensemble adapters have SERVICEINPUTCLASS and/or SERVICEOUTPUTCLASS parameters defined.

For example:

Class EnsLib.HTTP.InboundAdapter Extends EnsLib.TCP.InboundAdapter
{

Parameter SERVICEINPUTCLASS = "%Stream.Object";

Parameter SERVICEOUTPUTCLASS = "%Stream.Object";

...
}

What are they for?

Hi everyone, I have a SQL service that is working fine, except I don't want it to run on a schedule or continuously. I'd like to only run when requested. Run once and then stop until another request. Is there anyway to set up a service like that?

Hello everybody.

What I have is a criteria how to select "my" strings. What I need is to replace all of them with macro calls (using the same strings as arguments) in all classes of current namespace.

I was ready to write straightforward code, but at the last moment decided to ask the community: maybe I've overlooked a smarter option?

Any comments and advices would be great appreciated.

Hi,

I have a process in which i call a rest operation in a while loop, get a response in JSON format of 50 issues, with paging, meaning this call will happen until the total amount of issues will be returned. each JSON is parsed into a proxyObject, and inserted to a list. later the entire list will be sent to an SQL operation which will write the data in the appropriate tables.

The problem i'm encountering, is when i use the "ASSIGN" action, with insert at a certain key (context.i=context.i +1  for each iteration of the loop), i get an Error  that says that the value 3 is invalid key.

Trying to use AES encryption for a url.  I have a plain text string, a 16-byte key and a initialization vector.  I am trying to match a C# implementation that uses RijndaelManaged class with a  BlockSize = 128, Mode = CipherMode.CBC, Padding = PaddingMode.PKCS7.  The output of the $SYSTEM.Encryption.AESCBCEncrypt(text,key,IV), doesn't match what is coming out of C#.  All inputs into the $SYSTEM.Encryption.AESCBCEncrypt(text,key,IV) are converted to UTF8 as in the documentation.

Hi folks, I'm trying to pad my patient MRN to 10 characters before I do a SQL lookup in my BPL. I've tried various approaches, and have not been successful.

When I add a "code" statement with the following code, I get an error as below.

set context.NewID = "0000000000"
set $EXTRACT(context.NewID,10-len(context.PatientID)) = context.PatientID

ERROR <Ens>ErrException: <OBJECT DISPATCH>zS8+5 ^CHSLI.BPLQueryDatabaseforPatientID.Thread1.1 *Property 'NewID'

set $EXTRACT(context.

Is there a way to omit or skip rollback of some data changes during a transaction rollback? Maybe some sort of "autonomous transaction"?

The issue is with error logging in transaction. For example we may have in nested calls the following structure:
TS
<some code>
<error happens>
TRO 1
<error log to database>
but if this code is in another transaction, and that rolls back we lose error data.

Is there a way to do something like
TS
<some code>
<error happens>
TRO 1

<autonomous transaction start\flag>
<error log to database>

<autonomous transaction finish\flag>

so error log will be stored anyway?
