I am using a  %Stream.FileCharacter object  and LinkToFile API to write to a file on a folder. The file is written line by line . Something like  below:-

Set tStream =   ##class(%Stream.FileCharacter).%New()

Set tStatus =tStream.LinkToFile("MyFileName")

For i=1:1:X  { Set result = ..process(i) Do tSream.WriteLine(result) }

 An external process then picks up the file at a designated time.

I am unable to find any classes that will return the status of all the services in a production. Is there one available?

hi

   I backup  one database and restore it to antoher  new Caché server with ^DBREST, but I cannot view this db in the portal, why?

If I need some more operation?

Hi,

I am trying to send an email in a producion using the EMailAlert business operation, class EnsLib.EMail.AlertOperation using NHS Mail.

Has anyone succeeded in doing this? If so can you tell me how.

Thanks Sue

I'm a beginner for hs2014

I try to write text file in ASCII format (encode CP874) from HS2014 (run on RHEL)

I try to use

o file:"WNSK\CP874\"
o file:"RSK\CP874\"
o file:"WNSK\THAW\
o file:"WNS"

but output file still in UTF-8 encoding

please advise me

Thk.

I am working in Cache Objectscript where I need to process around 0.2 million data.

I am executing SQL query through "%Library.ResultSet"

Code Example:

Set tsRSet=##class(%Library.ResultSet).%New("<query name>")
Set status = tsRSet.Execute(<param 1>,<param2>)
While tsRSet.Next()
{
     Business Logic
}

Is there any limitation of the above code when the number of records the query is fetching is high.

If the query returns 0.5 million to 1 million record will my code work properly or it may break due to high volume of data.

I have 4 GB RAM and 2 GB global buffer in my production system.

At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards.  Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list.  What can we do to help?

A filtering function would be very helpful, so let's add a text input to the top of the page. We will bind this to a variable in the $scope - widgetFilterText so that Angular has access to the value we type in.

Hi,

We have a application developed in CSP and JS. Is there any way to make this application available in multiple language like Spanish etc.

We are ready to re-write the code in Zen also if it supports that feature.

Could any one of you please assist/advice a Solution to reach the required goal using Cache technologies, it will be a great help if someone has any sample code for the same.

Thanks

Atelier Users:

Has anyone found an Eclipse plug-in that provides the capability to connect to a Caché server and give the user a way to write SQL queries using the tables from that server? I'm picturing something like a "WinSQL"-client built as an Eclipse plugin.

I've found and tried the following, but I couldn't get it to connect to my local Caché instance.

http://eclipsesql.sourceforge.net/

I do a lot of SQL query building with the SQL tool on the Management Portal or $system.SQL.Shell() from terminal before moving the queries into my COS code.

I wonder if you could help me? I have a regular cache class that accepts a variable number of arguments in one of the methods. It works fine so I decided to add a method to my web service to make the call to the cache class. I get a compile error on the web service with error#5130.

Here is the cache class

class method GenerateFileFromSQL(file As %String, sql As %String, delimiter As %String = "", args...) As %Status

and here is the web service code that calls it:

ClassMethod GenerateFileFromSQL(file As %String, sql As %String, delimiter As %String = ""

Hi All -

I was wondering if the below query could be enhanced to automatically look back 24 hours from the current datetime the query is run. As is now I, of course, have to update the date range in the WHERE clause manually.

The query is just getting all MessageBodyClassNames, counting them and then doing an AVG on TimeCreated and TimeProcessed. Nothing too complex.

SELECT MessageBodyClassName, count(ID) as Count_Of_Messages, avg(datediff(ss, TimeCreated, TimeProcessed)) as avg_processing_time_in_seconds

FROM %PARALLEL Ens.

I am attempting to do two things with the mime types.

Collect the mime type from a stream(%FileBinaryStream) using this syntax: myCONTENTTYPE=stream.GetAttribute("Content-Type")

However, myCONTENTTYPE always comes in empty.

Set the CONTENTTYPE PARAMETER in the OnPage ClassMethod of a ZEN page, using this syntax: s ..#CONTENTTYPE=myCONTENTTYPE

However, I cannot seem to get the correct syntax.

I would appreciate any and all help. Thank you.

Awhile back we had someone write some code to Log messages like we did in eGate but with Ensemble.

ClassMethod LogIt(pComponent As %String, pMsgIn As %String)
{
 set vDIR="/ensemble/"_^OSUWMCInstance_"/logs/"
 set fs=##class(%Stream.FileCharacter).%New()
 set fs.Filename=vDIR_pComponent_".log"
 do fs.MoveToEnd()
 set vTM=$PIECE($ZDATETIME($HOROLOG)," ",2)
 //$ZTIME($PIECE($H,",",2),1)
 do fs.WriteLine(vTM_" : "_pMsgIn)
 do fs.%Save()
 set fs = "" // Close file
}

We found that the IO on this was slowing messages down, and those Operations that had high volume of message would fall behind.

I have built an Ensemble SOAP service (EnsLib.SoapService.Service) as a business service which accepts soap requests from another application. To secure the traffic between the SOAP service and the application i'd like to enable SSL. I see that in the management portal I can upload the certificates, chains and keys and save them as an SSL / TLS configuration. However, it is not clear to me how I apply this SSL / TLS configurtion to the soap service I am running.

Hi All,

I use SQL function JSON_OBJECT to get data as a JSON object.

However, sometimes I get error with function JSON_OBJECT when values contain [, ], { or }.

Error:

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

Unexpected error occurred in JSON_OBJECT() function execution of <JSON_OBJECT>.%FromJSON().Parsing error

For example,

Query: SELECT JSON_OBJECT('idSQL':id, 'content':content) FROM DocBook.

If you are developing applications that use CSP or Zen, or potentially any of the other InterSystems web-related stuff that's built on top of CSP, then it's important to know how to keep one particular secret.

A central part of the CSP security architecture is a server-side session key. "Server-side" because its value should never be revealed to the client that is issuing the web requests. If it is revealed, a malicious client might be able to use it to bypass your security and make your server do things you don't want it to.

Your session key is available as a property named Key of your %CSP.

Hi All,

         We can sent the file to FTP server using CMD prompt.

         When trying send file using cache FTP. it automatically logged out.

          While cache FTP access (read/write) FTP server it automatically logged out.

     S Server="test"
     S Username="test"
     S Password="test"
     I $L(Server)=0||($L(Username)=0)||($L(Password)=0) S Status="Invalid Credentials" Q Status 
     S ConnSt=ftp.Connect(Server,Username,Password)
     I 'ConnSt S Status="Couldn't Estabilish the FTP connection" Q Status
     ;
     ;Linking the file 
     D ftp.

Code coverage and performance optimization of code has come up a bunch of times already, so most of you should already be aware of the SYS.MONLBL utility. Often a visual approach to looking at code is much more intuitive than pure numbers, which is pretty much the whole point of this article series. This time we will take a slight excursion away from python and its tools and are going to explore generating heatmaps from ^%SYS.MONLBL reports.

As a quick reminder a heatmap is just a specific visualization tool, which gives us an overview of data where colors represent a certain value.

Hi!

I'm trying to insert a relationship from a parent object instance to a child object instnace programmatically. Ie, i want to do:

Do parentObject.childRefProperty.Insert(chilDobject)

where childRefProperty is defined by a string. I feel this should be achievable with $PROPERTY and/or $METHOD or maybe something in  $SYSTEM.OBJ.*, but can't quite figure it out. Anyone know?

Cheers :)

I have a client sending us data MLLP in base64 format. I'm using the EnsLib.HL7.Adapter.TCPInboundAdapter adapter. What setting do I change to accept the base64?

If you've worked with iKnow domain definitions, you know they allow you to easily define multiple data locations iKnow needs to fetch its data from when building a domain. If you've worked with DeepSee cube definitions, you'll know how they tie your cube to a source table and allow you to not just build your cube, but also synchronize it, only updating the facts that actually changed since the last time you built or synced the cube. As iKnow also supports loading from non-table data sources like files, globals and RSS feeds, the same tight synchronization link doesn't come out of the box. In this article, we'll explore two approaches for modelling DeepSee-like synchronization from table data locations using callbacks and other features of the iKnow domain definition infrastructure.

We finished our last lesson with our Widgets Direct page receiving a Welcome message as a property of a JSON object, which was unpacked and displayed on the page. However, we are on Lesson 3, and we still haven't had any talk of displaying widgets yet.  

Let's change that.  Widgets Direct are a leader in widget and widget accessories, so we clearly have numerous items to display.   To transfer this, we will need to declare and return our first array.  Let's go back to our REST.Dispatch class, and add this data to our Service.

Is there a way to do this? I found the way to store .gz files, but .zip files are different.

Aside from doing a print to PDF is there any way to use the existing DeepSee "export to PDF" functionality to export the entire dashboard rather than each individual pivot or chart?

Hello,

I work with trigger and I need afeter update make INSERT into LogTable value of prorerty of saved class.  This is what i have in this monent.

S className = ..%ClassName(1)
S cls=##class(%Dictionary.CompiledClass).%OpenId(className)
F i = 1:1:cls.Properties.Count() {
    S prop = cls.Properties.GetAt(i)
    S propName = prop.Name
    S value={propName*N}
}

How Can I get value given "prop".

Thank you

I have a newbie question.

How can a Cache/MUMPS process identify itself to either a process or system.

I have an application running in two different processes and/or systems and want to make minor changes depending upon which process it is in.

What is the easist way to do that.

-thanks

On the back of my recent post on writing bug-less code I wanted to raise a few suggestions (to ISC) that would help prevent certain types of bugs at compile time. I've probably missed a few, but these are the main ones in my mind. Please contribute more suggestions.

Btw, these also serve as potential gotchas for new COS developers.

I except that introducing these types of changes can cause legacy code problems. Particularly where developers do some interesting overloading of method arguments.

Cache Studio almost always crashes when I click rows in Call Stack view during debugging. Then Cache has to be restarted because last edited file remains locked.

Looks like I'm the only one who uses the debugger. Or is there a magic spell to make stack view working?
