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"

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:

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:

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).

Greetings!

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")

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.

Thanks and Regards,

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

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

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).

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:

Dear community!

What do you think about webinar "Declarative programming on COS"? I want to do such one.

I am going to tell about main points of declarative programming and how you can implement it in your real projects.

Please feel free to write your opinion here.

Please if you wish to become a member of such webinar write me a message to atygaev.mi@gmail.com with subject "webinar".

The goal of today's challenge is to copy data from one disk to another, problem is that the disks are not directly connected. Luckily they are in a huge grid, and you have to find a way to copy the data through adjacents disks, while honoring the disk usage (you cannot copy to a disk where data is already stored).

The input is a df-like disk usage listing.

Hi all! We have just released a new online course, Getting Started with ICM, that provides an introduction to InterSystems Cloud Manager (ICM) -- one of the new technologies coming with the release of InterSystems IRIS!

Hi, Community! 

Please welcome a new session recording from Global Summit 2017:

Backup Essentials - Protecting Your Data

Hello, this is going to be a stupid question, yea I know, there are no stupid questions.

Say, I have an Object Property, Name or Count or Title, or whatever.

How can I get a list, or find out all the different ways it can be expressed?

Example:

-Property Name As %Name;

-Property Name As %String="me"

-Property Name As %String [ Required];

But what other parameters, keywords, restrictions, lists, etc. that I can apply to this Property?

I have been search the I/S documentation and so far at least, I cannot find that sort of information, or in one place.

The challenge of day 21 is about scrambling passwords.

There are a few functions you need to implement that will do operations on a string :

Hi there,

The problem is, that I need use the property value of datacombo in other  datacombo with parameter.

The follow a example code: 

Hello Community,

I have a simple question but somehow hard to find the solution:

this is a property in my class:

Property RelationAID As ZenCrm.Relationtypes;

this is my method to save:

ClassMethod PopulateMatrix(tvar1, tvar2) As %Status
{
set RelationMatrix=##class(ZenCrm.RelationMatrix).%New()
set RelationMatrix.RelationAID= tvar1
set RelationMatrix.RelationAType= tvar2
do RelationMatrix.%Save()
quit $$$OK
}

However the 'set' line does not work for the 'related properties.

I have tried: set RelationMatrix.Relationtypes.RelationAID but this failed.

Any suggestion? thanks!

Application Performance Monitoring

Tools in InterSystems technology

Back in August in preparation for Global Summit I published a brief explanation of Application Performance Management (APM). To follow up on that I have written and will be publishing over the coming weeks a series of articles on APM.

We have an web application accessed using https, that uses CSP technology with frames.

The initial 'login' is via a single CSP page, which then redirects to another CSP page which creates the frames (4 in all) and loads a CSP page in each of those.  For the most part the frames load without error, but sometimes when logging in and sometimes while using the system ' 5916 Illegal CSP Request ' errors occur.

I say 'login' in inverted commas as a Cache login is not performed just an application login, I don't know if that's relevant so thought I'd mention it.

Does anyone know how to return the sys.process table with the corresponding configname item for each process? Also, is there a key for the Job Type field? 

I have restored one database from backup, but when I query from some of tables,   prompt error :

this error remain after restart Caché service

I can skip this error with %nolock in select query.

My question is: 

1. why there were locks after restart service?

2. Can I release/rollback these locks by sql so I can query without %nolock?

I have a query that I am attempting to run, but inner query is being rolled up into the overall query - per the optimizer (and jobexam observation).  While I know that if the inner query runs first, I will eliminate a number of records (making the result set smaller, and return quicker).

Just an example of what I am attempting to do:
