How to open a HTML Report using HTTP through Cache and How to Sending HTTP Request and Response from the Report?

I was wondering how you could take an exported obj and have it converted to an int/mac.

It would be convenient to be able to fetch the whole query result in one operation instead of looping through every row. A fetch_all() method or something similar would provide this functionality I guess. Is there a reason why this is not implemented?

I have a persistent class where I am logging each CCDA I receive. I want to store all of the providers associated to that CCDA (many to one). In a relational database, I would have a child table with a foreign key to the primary table. I'm guessing the equivalent to Cache would be 

1. Create a custom class (ProviderList) with the properties I want to store.

2. Add the class as a property of my CCDA persistent class.

Property Providers as Array of ProviderList (SQLProjection = "table/column";

Am I on the right track?

Hello community; this may seem odd, but I need to know if there's any way we could be using callin functions from a C application without knowing?  e.g. if other developers created some C programs that call in to Caché that we don't realize are running.  Is that possible?  If so, where would I look to see these programs?  Perhaps the server's task manager? 

Thanks --Laura

Here you have an easy way to write and execute COS code from your unix scripts. This way one does not need to write routines or even open Studio or Atelier. It can be an option for simple and small actions for instance things like installation tasks or compiling.

See sample bash script (compile.sh) to compile classes:

#!/bin/bash
#####################################################################
# Script to compile classes
# $1 = NAMESPACE
# $2 = ClassName
#
# For example:
# ./compile.sh "SAMPLES" "Sample.

Thanks for all replies in advance.

 Is it possible to modify a users security from a batch script?  If it is possible can someone point me to some examples or documentation?

With a routine like this one, you can quickly calculate how many lines of code you are working with. And it is not only for routines, it works for classes because remember that classes generate routines !

Here you have the routine source code:

LinesOfCode ;
    new SQLCODE,tRoutine
    set tTotalLOC = 0
    &sql(DECLARE ROUTINES CURSOR FOR
     SELECT NAME 
FROM %Library.RoutineIndex 
WHERE TYPE = 'MAC'
ORDER BY NAME)
    &sql(OPEN ROUTINES)
    &sql(FETCH ROUTINES INTO :tRoutine)
    while (SQLCODE=0)
    {
        write !

InterSystems is pleased to announce that Caché and Ensemble 2015.2.5 are now available as maintenance releases.

For a complete list of the corrections in 2015.2.5, please review the release notes .

Caché and Ensemble are available for the same platforms as 2015.2.4.  The complete set of supported platforms, including specific point releases and patches, is detailed in the Supported Platforms document .

The HealthShare team will announce availability of its products separately.

The build corresponding to this release is 2015.2.5.953.0

At Global Summit back in April, in his keynote speech, John Paladino mentioned that improvements to our documentation search were being made.  You might have wondered, since things seemed to go quiet, whether anything was really happening.  Well, we had an internal demo of some of the upcoming features recently, and the new capabilities look really cool – searching documentation has been frustrating for InterSystems staff too!  So, I thought it might be good to pass on a few details to give a taste of what is coming.

Interesting anecdote I want to share. Not 100% Caché related, but I hope it would be useful.

When CSP Gateway is configured on IIS, opening CSP Gateway Configuration page is prohibited by default -- as IIS blocks URLs with '/bin' in it.

In our documentation we advise to add <remove segment="bin" /> to applicationHost.config file. That is correct.

Recently I had problem when manual editing file Windows\System32\inetsrv\config\applicationHost.config has absolutely no effect on IIS.

Turned out (http://serverfault.com/a/599865) IIS was 64-bit and notepad++ that I used for editing was 32-bit.

Very new to this side of cache.... 
So, currently in the habit of keeping all users forever, up to over 5000... ? is what if we decided to start deleting old users who have been gone from the company, how would it affect any account level information? notes, payments etc....  Is there any documentation anywhere that would answer this or describe this process or maybe best practices??
Sorry if this seems stupid but i am working on a proof theory for work.

The goal of this writing was to illustrate how to restore backup before the patch would be applied. The alert notes that: 

The risk can be avoided by applying journals from the beginning of the journal file that was switched to at the start of the backup, rather than accepting the default of starting from the journal marker position.

Having non-patched Caché 2015.1.4, I ran sample database backup and restore just to get where I should answer "No".

A few people wrote to me asking about the infrastructure behind the Atelier Server implementation. Its neat and a worthwhile story to share so I am writing it up here as a post on the community. I want to go in to a little detail on why it was needed and then I will outline in detail how we went about implementing this.

So why did we need to give people a “server in the cloud”? Atelier is the new IDE for InterSystems products. It is Eclipse based and implemented in Java so it is cross platform. The communication between the Atelier client and the server is REST based over http.

As some customers recently received new license keys, I received some questions why their new license does not seem to work, other than the expiration date being reached. So far I was able to solve all of them with this short list of things to look at.

1. Is the date on your laptop set properly?

2. For Europe (and possibly other regions): the expiration date in the cache.key file is in US format, MM/DD/YYY, while most people there are used to DD/MM/YYY. This is obvious if you have an expiration date like 11/30/2016, but not with dates like 3/12/2016 (expires in March, not December).

What are the difference between Caché and Cache.

Is there a way to download just the studio and not have to download cache to get it?  

This text is a continuation of my article where I explained the structure a Caché database. In this article, I described the types of blocks, connections between them and their relation to globals. The article was purely theoretical. I made a project that helps visualize the block tree - and this article will explain how it works in great detail.

Hi,

Thanks a million for taking the time to read this.

I'm calling the functions $ZF(-`1, <path to EXE>) and $ZF(-2, <path to EXE>) from Cache code. The exact code I'm using in Cache Studio is given below.

/// Test the functionality of ZF(-1) and $ZF(-2), 
Class %SourceControl.UnitTest Extends %Persistent
{
Parameter PATH As %String = "E:\VCS\CommandExecutor\bin\Debug\WindowsApplication.exe";
ClassMethod Test()
{
Do $ZF(-2, ##Class(%SourceControl.UnitTest).#PATH)
}

Now when I run the command in the Cache Terminal, as given below,

>do $ZF(-2, "E:\VCS\CommandExecutor\bin\Debug\WindowsApplication.

We have a very old green screen application which is currently producing PCL "documents". I want to update this to produce PDFs - are there any shortcuts / tips? I'm aware Zen Reports can allegedly do it, but I want to avoid that route if I can.

Hello,

First sorry for my english :)

I'm looking for a solution to reset the cursor of a query in a csp page.

In my code I do:

<csp:query name="users" classname="UserId" queryname="Find">
 <csp:while condition="users.Next()">
         ...
 </csp:while>

And 100 lines after I have to do exactly the same ...

Is it a way to do the while without do the query again ?

Something like users.Reset() ??

Thanks a lot for your help

Sébastien

I experience this constantly with Cache SQL.  Especially when querying the ATNA log.

SELECT TOP 400000 * FROM HS_IHE_ATNA_Repository.Aggregation ORDER BY ID DESC

That took 12 seconds.  I then upped the number to 500,000 and it took 185 seconds.

Shouldn't the execution time scale proportionately?

If I run the 500,00 query again it takes 2.4 seconds.

How to parse a URL in Caché:

Let's pretend you are working on a project where you may be retrieving a URL for some purpose and you have the need to be easily able to parse apart that URL to get the various components that make up the URL.

Here's how to do that:

Note:  This example assumes you have a variable named sURL that contains some url (i.e. http://www.intersys.com/main.csp?QUERY=abc#anchor) and you will be creating an array of the URL component pieces, where the array will be named aComponents.

In your class/routine, add the following code:

Do ##class(%Net.URLParser).Parse(sURL,.

I have to connect to an external database and I'd like to use the JDBC SQL Gateway.

I followed this tutorial [1] to create a JDBC SQL Gateway and after configured it works as expected, but I don't know

how use this connection into source code. Maybe these other tutorial is related [2] and [3].

Hi

I have been working on changing a web application from using %FileBinaryStream to storing and serving the file content from a %Stream.GlobalBinary property, stored in a new database.  I have managed to migrate the data across, and have also been able to redirect the stream so that it is being served through the web link.  However, the previous method set attributes on the File stream to have the stream be rendered as the original file type through MIME, using this code

do stream.SetAttribute("ContentDisposition","inline; filename="_filecvt)

This method is not supported by %Stream.

Difference between function , routine and procedure in object script.

Background

Caché 2016.1 introduced some very powerful JSON features.  Unfortunately, the syntax used in the 2016.1 release is going to be changed in the 2016.2 release to bring it closer to Caché ObjectScript syntax.  This will mean that code that works in 2016.1 may not be forwards compatible.   See this announcement and this article for more details about the changes.

I can't able to access the management portal in tcp the cache is run on different port no 57812 plz i want immediate rply soon

Hi All,
