In short, I wanted to react on CPUusage warnings and alerts with my own actions. It seemed that it was possible in my Caché version (2015.1): 
http://docs.intersystems.com/cache201513/csp/docbook/DocBook.UI.Page.cl…

But all my attempts silently failed. Callback code was as simple as possible: 

Class %z.Monitor.Health Extends SYS.Monitor.Health.AbstractCallback{/// This method is called for every Health Monitor sensor reading.<br>///...
Method Callback(type As %Integer, sensor As %String, value As %String, mean As %String, sigma As %Stri

On the "General" tab of the Rule Editor there's a field called "Production Name".  The doc says (my emphasis):

The name of the production in which you expect to use this routing rule.

Does anyone know where this value is used?

Is it safe to set this field blank?

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

I was thinking that Ensemble could maintain the SSH tunnel, 

which would improve our detecting of issues.

Has anyone done something like this?

I see that the  class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself.   Instead, it appears 

to return a handle into the tunnel.     It will work a bit differently.

Thanks

I have list of business services in my ensemble production.

Often, my business services which are in green color turns to red color and asking for update and restart the services.

I would like to know, how to identify which business services are turned to red color.

Help me restart the service individually by code.

Thanks,

Ashok

Hi,All,

        I did a small coding for the HTTP request and HTTP response. When i tried to use a server with ping i was able to get a response from the HTTP request. But when i tried the same with HTTP response i am getting a empty value in the response why is that?

Thanks in advance.

aa=$zwc(411,1,1,3)/*$bit(1,3,5)*/
bb=$zwc(403,1,0,2)/*$bit(1,3)*/

Is there a handy function to test wether one bit string is covered by another one bitstring? For example, "bb" is covered by "aa".

I currently implement this by one AND operation and then do a bitcount, I just want to know any default function is already out there.

Thanks.

Hello,

I was wondering if there is a way to maybe temporarily alter the [Private] tag dynamically or any other way to run a Unit test against class method, which has been labeled as [Private]?

I mean, I understand there is a workaround to create a non private class method inside this class, which will in turn call this private method  and run a Unit test on the non private method, but I am looking for a way to do this without altering the original class.

Thank you,

Alex

Guys,

Can you please guide me to create a RESTful API in our cache with JSON response. 

Caché will not change the cryptographic settings in an existing TLS configuration when you upgrade.  This means that unless you've updated them yourself, you're still using the values from the very first version you started using SSL in.  

If you've upgraded since creating your TLS configurations, take a moment to look at the enabled protocols and ciphersuites to make sure you've enabled all the versions you want, and disabled the old versions you don't want.

When executing a business process I'd like to share the Login Token from an external system retrieved via one of my business operations across multiple process instances. This means I need to persist the token somewhere. What would be the best approach/pattern to implement this?

The primary idea I had was to store the token and a timestamp in a persistable object and then write a single method in the Business Operation that retrieves the token.

Dear community!

I'm currently working on MessagePack implementation by using Cache ObjectScript.

I try to choose suitable representation for binary array.

Should I use $lb or $c or smth else for it?

How do I set an URL when I post a httpRequest via SendFormArray of my Ensemble Business Operation. Here is my code: 

Class CareHome.RestApiClient Extends EnsLib.REST.Operation
{
Parameter INVOCATION = "Queue";
Method Login(pRequest As CareHome.Request.LoginRequest, Output pResponse As Ens.StringResponse)
{

set tURL = ..Adapter.URL_"login/login"

set httpRequest = ##class(%Net.HttpRequest).%New()
 set httpRequest.ContentType="application/json"
 do ..ObjectToJSONStream(pRequest,.jsonStream,"aeliw")
 set httpRequest.EntityBody = jsonStream
  
 set tSC = ..Adapter.SendFormData(.tHttpResponse,"POST",httpReques

Initial questions have been answered. Expanded the post with actual code (see below)

So, I'd like to update one (and preferably) more context-fields in my ensemble BPL business process based upon the information in the request that initiates said BPL proces. I got a few questions about that:

1.

I have an application in Cache 2013 (No Ensemble) which need to consume a REST web API over internet.

Can somebody please help me by pointing out the documentation or provide me code sample  for consuming the REST API from a routine/class.

I am using Cache 2008 (No Ensemble) .

Hello!

Suppose I have a package with classes which I want to rename. All these classes are persistent and they already have a lot of data stored.

The best I can think of to do is the following:

1. Duplicate class definitions of old classes, rename each of them and save
2. Write a routine to copy (duplicate) all the data from old classes to new ones. (which is not trivial at some point)
3. Refactor all the application's code to use new classes. (which may not be trivial at some point too)
4. Test the things above
5. Load new code to live environment and launch the script
6. Hope that 5. finishes successfully.

Hello.
We're about to implement an application that could use WebSockets intensely so before we head to that direction we need to figure out about how some few things work. That being said, anyone care to give me some enlightenment?

• What's the criteria for a new session to be created when using WebSockets?
• What's the factor for calculating how many licenses to would be used when SharedConnection  is enabled for WebSockets?
• Is there a way to use session in a way that it would optimize the license usage for a single user?

This is the 25th and last challenge of the 2016 series of Advent of Code.

In this challenge,  you have to send a signal out,  using the assembunny code interpreter that  we had to make in earlier challenges.

There is one extra instruction added to the assembunny language, which outputs a value (out x).

Using the instructions as input (see http://adventofcode.com/2016/day/25 for the

Hopefully someone has an answer on this, I cannot find any example or understand from the documentation how to acheive this.

I have a SOAP header subclass

Class AddressType Extends %SOAP.Header
{

Parameter ELEMENTQUALIFIED = 1;

Parameter MAXLEN;

Parameter NAMESPACE = "urn:registry:1";

Parameter XMLNAME = "urn:LogicalAddress";

}

In my  %SOAP.WebClient I use it like this:
set customHeader = ##class(AddressType).%New()
do ..HeadersOut.SetAt(customHeader,"AddressType")

Which results in
...
<SOAP-ENV:Header>
<urn:LogicalAddress xmlns="urn:registry:1" xmlns:hdr="urn:registry:1"></urn:LogicalAddress>
</SOA

Is there any way to specify in which order indices are built during:

• %BuildIndices
• %Save

So far I think they are built by name order.

Today, you need to find your way through a maze (again). There are 8 points of interest in the maze, and you have to visit them all, starting with point 0.
You may visit some points more than once, in random order. The challenge is to find the shortest path through the maze while visiting all points.

The maze looks a bit like this :

Dear community!

I have problem with index NULL value.  Unique index doesn't work for this case.  If I use insert and one of parameter is "NULL". Message of constraint doesn't appear and row is inserted into table successfully.  How Can I use index with NULL?

Class TestClassIndx Extends %Persistent
{
Property name As %String [ Private ];
Property age As %String [ Private ];
Property country As %String [ Private ];
Index IndextestUniq On (name, age, country) [ Unique ];
}

INSERT INTO TestClassIndx (name,age,country) VALUES ('1','2',NULL)

Hi everyone!

I'm restoring big database (1.8 Tb) from full backup to another host.

This host is weak (4Cpu 4GB RAM), so ^DBREST already works for 50 hours.

Is it possible to view restore process progres? I would like to know what  time it will take to complete?
 

Hi Guys,

Can you please guide me on how to develop the machine learning concepts like as Chatbots, voice recognition, etc...

If any lead would be appreciate. 

Thanks in Advance.

I have been working on a project in our Dev environment which resulted in processing a few (million) HL7 messages, and I thought it would be a good idea to purge the namespace in a controlled way. My concern was when it hit the day where the scheduled task would purge 'the day of a million messages', it would fill the Journal Drive quite dramatically and would happen overnight resulting in triggering a response from the poor person on out of hours support.

My idea of a controlled way was to:

• Run a backup
• Disable Journalling
• Run Purge
• Compact and Truncate DB
• Re-enable Journalling

Now, I got as far as

I ran the below query in three different modes.  Coordinated Universal Time is 5 hours ahead of Eastern Time so there is difference in value from column 1 and column 2 in ODBC, Display mode, but not in Logical Mode. By default the query executes in ODBC mode when we query the data from outside world(via ODBC connection). 

I don't know  why query 2 and query 3 outputs different from query 1.

Query 1. Ran in Logical mode, DATEPART() took in memory stored timestamp data(stored in UTC)

'Hour ' returned are same for both the columns

Query 2. Ran in ODBC mode, DATEPART() took in memory stored timestamp

Remember the assembunny language we had to code on day 12 (https://community.intersystems.com/post/advent-code-2016-day12-leonardo…)?

There is a new instruction we have to implement which toggles an instruction x lines away (further or back).

• For one-argument instructions, inc becomes dec, and all other one-argument instructions become inc.
• For two-argument instructions, jnz becomes cpy

I have an Ensemble installation and just build my first RestService (using %CSP.Rest that forwards them to my Business Service). This works nice and fine when I use postman to make REST calls over http (port 57772). However when I attempt to make a request using https over port 443 I receive the following error:
