set record = ##class(Test.Person).%OpenId(1)

write record.Name

2. Option 2

Microsoft Office has components for using in third party applications: COM Objects for C++ and Interop Assemblies for .Net programming.

Many Cache projects used to include calls to those libraries. However, recently this solution started being problematic.

There are two main reasons - legal and technical. Let’s check the details.

Microsoft technology support

Microsoft is supporting Office Automation only for desktop computing. 

It shall not be used for server computing, as they offer Sharepoint for this scenario.

Recently I wrote about automatic removal of system methods from the codebase.

Today, I'm ready to present you a working solution (codename: SMR) for this task.

Hi all,

We've found that in most cases when we open a new CSP session the CGI varaiable %CGIEVAR("HTTP_COOKIE") contains the client name.

It looks like that : "state=SYSADM%3A0; Username=Urish; CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11..."
In some other cases this CGI only contains  $zv - like "CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11 2013 23:20:33 EDT"

We are searching for a way to get the username (we need to stop using activex controls, like WScript.Network--> dNE

This is a list of all the posts in the Data Platforms’ capacity planning and performance series in order. Also a general list of my other posts. I will update as new posts in the series are added.

You will notice that I wrote some posts before IRIS was released and refer to Caché. I will revisit the posts over time, but in the meantime, Generally, the advice for configuration is the same for Caché and IRIS. Some command names may have changed; the most obvious example is that anywhere you see the ^pButtons command, you can replace it with ^SystemPerformance.

We are trying to understand how websocket connections from a javascript client may timeout in cache. Does anyone know if and of the session timeout or any other timeouts apply to any synchronous websocket connections? I have not been able to prove that they do timeout at all.

Hi,

I have a requirement to convert uname -n (Unix comamnd) with its equivalent Cache class. Can anyone help on this please

I tried using the DeepSee Troubleshooting guide but the suggestions weren't working.  Let's say that the source data we are using to build the cube on has a value out of range. This would cause the cube build/update to fail. How do I see the error log that explains which field has the value out of range? Please be detailed on exactly what command I should enter and where I should enter it in.

I assume that I go into a terminal session and to the correct namespace that we are building/updating the cube on, but the DeepSee Troubleshooting guide doesn't give that detail.

This article explains the basics of OpenVMS file structures, from a Caché prospective, and what you need to know to read and write any OpenVMS file with Caché, even the files with difficult file structures.

On UNIX and Windows all files are just a stream of octets (eight-bit bytes). Assigning meaning to those octets is done entirely by convention. Those conventions are rather simple, even if slightly different on UNIX and Windows.

Hi All,

We are accessing the InterSystems`s cache database via UNIX ODBC and displaying the data in PHP website . Recently we have upgraded the PHP version to 5.6.  We are getting the nondisplayable characters (�) for only strings. But the numbers and date fields are displaying correctly. 

While querying the database via ISQL everything working fine (No Special characters).

I have looked around the internet and found the PHP 5.6 changed the default character to UTF-8.

For this issue anything, we can do from cache side.

cache version :

Cache for Windows (x86-32) 2016.

Is there any alternate way to run .exe in Ensemble without using $zf command?

Hello, I would like to know if CACHE has any limitations on uploading files.
Why am I asking this, why am I going through a problem here.
What happens is that when uploading files or images that are larger than 2.7 MB CACHE is limiting the size to 2.7 MB, any file larger than that is saved corrupted.
Already at the time of uploading the file or image, CACHE is limiting the size of the file to 2.6 MB.

Hi,

I have a requirement to replace $ZF("%ZSET_DIR","/hold/rsm") to its equivalent Cache Class. The $ZF("%ZSET_DIR") sets the Current folder equivalent to "cd" command in Unix.

Can anyone help on this, please

If you spend a lot of time working with javascript, json and html and you are new to Eclipse / Atelier you may like this tip. 

 Instead of the default Atelier HTML you can install a JS plugin for eclipse which works quite good handling javascript files, allowing you to see functions, color syntax, etc. The one I used is the JSDT.

I tried to make atelier look more like XCODE with this simple trick or tip: change the default font to SF Mono and size 14.

To do it I did:

1) Install SF Mono font in the system which is the default font for XCODE and needs to be installed in order to use it.

You can find it in: /Applications/Utilities/Terminal.app/Contents/Resources/Fonts

Double Click SFMono-Regular.otf file and install it. You will get a warning of "serious problems" but it will work all right.

2) Then, in Atelier, go to Preferences / General / Appearance / Color and Fonts The choose Text Font (In Basics category) and Edit.

Hi Everyone,

         I have frequently received this below error message in my ensemble 2009 Cconsole log.

         " 11/08-13:05:06:114 (9784) 2 Skipping SET due to compare and swap failed on ^["^^e:\test\data\"]Debug("CalcTotal1") for records in e:\test\data\ addr=39745548 "

        Please explain this, am very much trouble with this alert. And also want to know it will cause any system hangsup ?

please response quickly. Thanks

I have an amazing tool called 7edit for editing and sending HL7 v2 messages.  I've searched hours for a similar tool for HL7v3 without luck.  They're all web based, crappy, broken links, etc.

Thanks for all replies in advance.  In monitoring our audit log we are getting the error below.  We have 4 different servers running CACHE  2014.1.1 and this is happening on all 4 of them.  I have not been able to find what process is trying to logon but it is happening every 30 minutes.  We have no user processes that are running so this has to be a CACHE process.  Does anyone have an Ideal what could be running to cause this?  What kind of trace can I run to determine what process is running it?

I need to catch the user using a bookmark to get into the application in the 'middle'; i.e. the user is getting into the application not  at the home page.  I've tried OnPreHTTP to redirect, but I can't catch the new session, and it doesn't redirect.

How can you redirect to the home page upon login?

Thanks,

Laura

Hi,

Currently i am building a CSP application using Intersystems cache to automate few tasks in Ensemble. Basically, I have 2 .csp class files, file1.CSP and file2.CSP in namespaces namespace1 and namespace2 respectively. On satisfaction of a condition I forward the request from file1.csp to file2.csp. while forwarding it prompts me to enter the log-in credentials again as the second .csp file is in a different namespace. Is there any way i can bypass the login screen while forwarding the request from 1 csp to another (as i am using the same credentials for both the namespaces) ?

Hi,

How to post and get data using php. I'm using a php external url. In the body in parsing the request as xml and when i execute this using fiddler it response the result as xml but when i consume it in classmethod it fails. I don't have a wsdl file how can i work it out?

What is a core file? and When are they use­ful?

In this post I would like to talk about the syslog table.  I will cover what it is, how you look at it, what the entries really are, and why it may be important to you.  The syslog table can contain important diagnostic information.  If your system is having any problems, it is important to understand how to look at this table and what information is contained there.

hi,

I have created a asp web service and it is hosted in our internal server. How can i consume that web service in cache class method? It is a soap web service with xml input and xml output. It works fine in all the browser.

This is the first article in a series discussing how to regain disk space from Caché databases at the operating system level. This introductory article discusses Caché database growth and gives an overview of various methods you can use to return unused disk space that is allocated to database files back to the file system. But before we talk about returning space to the file system, let’s first review how does it get allocated in the first place.

Caché databases always have the name CACHE.

Environment: Cache for Windows (x86-64) 2015.2.2 (Build 811U) Thu Mar 3 2016 12:55:48 EST [HealthShare Modules:Core:14.01.351 

When try the following to send back SOAP Fault, is the following correct way?

Set fault=##class(%SOAP.Fault).%New()
Set fault.faultcode=$$$FAULTServer
Set fault.faultstring="Processing Error"
Set fault.detail= "Error on server"
Do ..ReturnFault(fault)

Got the error 

Hi,

I am using the &sql () tag to retrieve the value from the Cache DB.

below is the piece of code i am using:

script language="cache" method="retrieveDetail" arguments="pVariable" returntype="%String" &sql( select columnA, into :tempVariable1 from TABLE where COLUMNC = pVariable

quit tempVariable1

i have to return the ColumnA value back to the calling procedure.

can i know how it can be done ? since i am getting an javascript error.

Hi -

When upgrading a Health Connect deployment from 2014 to 2016 do I HAVE to recompile? or is the "just upgrading" enough?

Beginning in Caché 2013.1, InterSystems introduced Outlier Selectivity to improve query plan selection involving fields with one atypical value.

In this article, I hope to use an example 'Projects' table to demonstrate what Outlier Selectivity is, how it helps SQL performance and a few considerations for writing queries.

Selectivity

First, let's take a quick look at Selectivity. Selectivity is meta information about the values in one column in a table.
