I have tried to create Ensemble SOAP passthrough operation following this guide.

Here's my production configuration (after steps 1-4):

Class Passthrough.Production Extends Ens.Production

Step 5 of the guide says to open the url:

http://localhost:nnnnn/currencyconverter/ConvertCurrencySOAPPassthrough…

have two web applications in a namespace:

• /csp/passthrough
• /passthrough

 I have tried calling the following urls:

• http://localhost:57773/passthrough/PassthroughService/CurrencyConvertor.asmx
• http://localhost:57773/passthrough/PassthroughService/CurrencyConvertor.asmx?CfgItem=

What is APM?

I am talking about Application Performance Management at global summit, and several people have asked what that means so it is time for a bit of an explanation.

APM or Application Performance Management (sometimes referred to as Application Performance Monitoring) has a very good (if complicated) explanation on Wikipedia but to me it just means looking at performance from the users’ point of view and the level of service provided to them.

Hi All, I tried to connect Crystal report with Cache 5.0 Its Show Crystal Report error as "The report you requested requires further information." How to resolve the issue in C#.

Hi everybody, We have written a convert from Punycode. This is reformed from javascript. Perhaps many non-English systems need to use this feature in domain name resolution. Anyone can use and change the code as needed.

Recently upper case ß was defined as an official character for German
how can this be adjusted in Caché 2017 ?

Hi All,

We have a application currently running on Zen framework, now business wants to use Angular JS as their front-end technology for any future release but they don't want to upgrade the existing the modules which are already there in Zen (as of now).

Hello,

I try to create an ECP between to CACHE server.

The ECP is working, the remote DB is created and the namespace is created and linked on the remote DB.

The table appears on the server but when I try to access I get this message:

ERREUR #5540: SQLCODE : Message 400 : Process 4076 failed to compile Cached Query Class %sqlcq.###.cls6 with these errors: ERREUR #5002: Erreur Cache: <COLLATION NOT SUPPORTED>getdependencyclasses+54^%occDepend SQLTEXT: SELECT ...

My servers have different cache version: 2016.2 and 2015.2, perhaps that's my problem ?

Thanks in advance

Sébastien

Hi! I am trying to automatically populate an array property of cash amounts keyed by currency ("GBP", "USD", etc). This property needs to be NOT stored on the database and visible via SQL and the cache object. 

Here's my attempt. Ultimately the array will be populated based on the the some child classes, but for now I'm just hardcoding it:

 Property Amounts array 

 GetTotalAmounts() 

This compiles but accessing via SQL gives:

[SQLCODE: <-350>:<An unexpected error occurred executing SqlComputeCode>]

Via object:

Hi, Community!

Recently we announced Developer Community Meetup in Cambridge, MA. Let me describe what is it. 

Meetup it's a one evening event where you can enjoy some sessions by presenters (today InterSystems engineers, tomorrow you can be a presenter) and chat with local developers and InterSystems developers, engineers and product managers (depends on who is in town) and discuss your problems, experience, and success with InterSystems technologies.

InterSystems would provide the place, technical sessions, some food and beverages. 

We think the Developer Community would benefit from it.

In this article I would like to tell you about macros in InterSystems Caché. A macro is a symbolic name that is replaced with a set of instructions during compilation. A macro can “unfold” in various instruction sets each time it is called, depending on the parameters passed to it and activated scenarios. This can be both static code and the result of ObjectScript execution. Let's take a look at how you can use them in your application.

By now it's a commonplace how to implement a basic REST API in Caché and there is good documentation about it here: REST in Caché

A question that comes up from time to time is:

How can I make a parameter in my REST url optional?

Simply put, is it possible to create a URL map in Caché that maps a URL like this:

http://server/API/object///old

While this might look odd, this is actually a valid URL. You can read the details in RFC3986 section 3.3.

The framework provided by %CSP.Rest actually allows us to create maps that match the above URL.

What is a major difference between $case and $select?

hi

  I query large mount of rows from one table with JDBC, and will prompt <store> error.  I found that it was out of process memory (default 16M, max 49M in version 2010.2) .

  so my question is : how to release memory for large  mount of rows  query? or how to resolve this error?

I get a third party routine which outputs some messages to standard output during execution.

Is it possible that I could direct the messages to other device so my terminal would never see this messages?

Thanks.

Greetings,  

What methods are available to position a cursor on a screen to begin writing as not to disrupt other areas of the screen?  I have used ?# , ie: ?5 but this is destructive from the let to character 5.  I would like to enter a command that will position at row,col and then start writing?  Can I create a window in a window type display to write text and then when done viewing, remove it?

Please advise,

Thanks in advance for everyone's time.

I have a query string that I am creating programmatically, based on some user inputs.  The user might search on 5 fields, or 8 fields, or no fields.

In my sql statment, some of these fields require parameters in the %Execute statement.

For example:

if user picks lastname, sql = "select * from person where lastname = ?"

if user also picks age, sql = "select * from person where lastname=? and age > ?"

I then have these lines of code to create my result set:

set statement = %SQL.Statement

statement.%Prepare

resultset = statement.%Execute(param1, param2)

-- but it might be 

resultset = statement.

Type 1:

^global(key1,key2,key3,val1) = ""
^global(key1,key2,key3,val2) = ""
^global(key1,key2,key3,valn) = ""

Type 2:

^global(key1,key2,key3) = $lb(val1,val2,.....valn)

the number of val may be just dozens, but also possible to 10K

Thanks.

Hi
I would like to follow any change made in the production IE -
date,time, user,production,service/process/operation - name, item changed, value before change, value after change.
Is there a way I can get this data & trap the act of change in order to log this data.
Thanks Simcha

Hi Community!

Please find the Developer Community video of the week on the InterSystems Developers YouTube Channel:

More calls in parallel to a single .Net Gateway can yield better performance, but too many could cause problems. What is the "Right" number? What do you do/recommend?

Hi,

Is it possible to use the value of a column that is populated by its own subquery,  in the WHERE clause of the outer-query ?

The following fails (it does not parse syntactically):

SELECT A, B, (SELECT S1 FROM Table2) "C" FROM Table1 WHERE C>10

I guess I could wrap it up as in inner query of it's own - this way (which works) :

Select * from 
(SELECT A, B, (SELECT S1 FROM Table2) "C" FROM Table1)
where C>10

but I was wondering if there was some syntax in the original snippet that I could do instead.

Thanks - Steve

Hello! So, my knowledge on the Cache database is extremely limited, and I was hoping I could find some assistance here. I'm connecting to the DB via ODBC. The table(s) I'm interested in are named as such nameYYYYMMDD. So each day, a new table is created with logs. We'd like to grab these records each day, for the previous day's logs. 

My question is, since the table name changes every day, how can I go about automating this? Can I craft a variable that is the table name plus some date functions and use that?

Hi all,

I was wondering if there is any way to trigger the compilation of a class based on the compilation of another (unrelated) class. For example:

Class 1 = test.class

Class 2 = test.class.type.one

Class 3 = test.class.type.two

Every time class 2 or class 3 is compiled in Studio I would like to have class 1 automatically compiled as well.

The reason I need this is because class 1 has a method with CodeMode set to objectgenerator which generates some code based on what is found in classes 2 and 3.

Below are the output messages when Cache start.

Allocated 178MB shared memory: 1MB global buffers, 26MB routine buffers

I try to configure the global buffer size by [System] -> [Configuration] -> [Memory and Startup] from SMP,

but it seems like the changes does not apply to the global buffer.

Thanks for your help.

I have a class and I would like to dynamically change its selectivity attribute in run-time and then call $system.OBJ.Compile to

recompile the class. I have changed the selectivity to a global, but it seems like it does not work. Any suggestions? Thanks.

<Property name="field1">
<AverageFieldSize>8.91</AverageFieldSize>
<Selectivity>^selectivity</Selectivity>

what's the corect syntax?  Thanks!

InterSystems' iKnow technology allows you to identify the concepts in natural language texts and the relations that link them together. As that's still a fairly abstract definition, we produced this video to explain what that means in more detail. But when meeting with customers, what really counts is a compelling demonstration, on data that makes sense to them, so they understand the value in identifying these concepts over classic top-down approaches. That's why it's probably worth spending a few articles on some of the demo apps and tools we've built to work with iKnow. 

In the first article in this series, we'll start with the Knowledge Portal, a simple query interface to explore the contents of your domain.
