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!

Upgrades - Minimizing Business Disruption

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?

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>
</Property>
 

Hello, I am writing to request assistance on an issue I appear to be having when accessing Ensemble. I have it running on a Windows virtual machine, on a Mac laptop, and am trying to access it through the emergency ID account. When starting Ensemble through the command line window using ccontrol start ENSEMBLE /Em... I get an error and Ensemble does not start. Below is the error message I am getting when checking the logs:

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.

Hi,

I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.

The signing is done using openssl.

This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.

The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.

The content is signed using RSA SHA256 with PSS padding.

I've had a look at $nconvert, $sconvert, etc., but can't get to a solution.

Is there a

Greetings, 

How can I store a global name in a variable, ie: x="^G" and then use x like this, as if it were the global:  y=$o(x)  ?

Please advise,

Thanks... 

Greetings,

If given a global, how can I discover information on that global?  More specifically,  how can I discover how many indices it contains?  ie:  ^G(1,2,3,4,5)   How can I discover that there are 5 subscripts within the Global ^G if I did not already know.

Please advise, and thanks in advance for everyone's time.

It is my understanding that when a routine accesses a global it is temporarily stored in global memory. While the global is within global memory, any other routine would be able to readily access the global from memory and not from disk so long as the same node is being utilized.

For example, RoutineB() would be able to access ^Global(1) and ^Global(1,2) since RoutineA() utilized them, but RoutineB() would have to read ^Global(1,7) from disk as it was not utilized by RoutineA().

For my own sanity, I wanted to reach out and obtain clarification from the community as I have recently begun to

Hello mates,

When turning on the “Archive IO” option within the business operations, it provides us the capability of seeing the input and output communication with external systems. For instance, watching the messages sent out + ACK message sent back .

Our production has got a scheduled task that runs daily (by default I guess, as many others) and is in charge of purging “Errors and log files”. And this is likely to be linked to the “Archive IO” feature, right?

The thing is, after tweaking the variable to keep it for 7 days, it doesn't seem to be working, as messages older than 1 day will be

Hi everyone

Is there any way to change a class definition (especifically a query definition during the compilation time)?
The idea is: 
    I have an abstract class with a parameter where I will define the ROWSPEC of a query and some methods to populate e temporary table
The implementation class will override the parameter, specifying the ROWSPEC of this implementation, and the methods will populate the rows in the same format as the ROWSPEC.

I want to change the ROWSPEC of the inherit query according to the implementation of the overriden parameter.
What I've already tried to change the parameter

Hi 

I have two persistent classes defined. Lets call it Parent and Child.

Child class is one of the property of Parent Class.

I would like to define a index on Child class.

So what is the default behaviour I defined a index on a non simple data type member?

Any possibility that I could customized the behaviour ? For example. Child class has three properties.

Could I configure the index to index any combinations of these three properties?

Thanks for your help.

Hello,

We need to consume files (right now using FileInboundAdapter) with a strict order.

Example:

File order will be A, B, C. Suppose A, B and C will be the names of the files.

Then B will never be consumed before A or after C.

How deal with this? Any idea?

I'm trying to recreate a smaller copy of our DEV machine on a sandbox instance.  I installed a new instance, and thought it would be a good idea to copy over a few cache.dat files from the critical namespaces (but not all of them), and start from there.

However, I can't compile any UI files in my new instance because I'm getting a <PROTECT> error on the %qCacheMsg global -- for any element that displays text (i.e. the first <label> that's encountered) the generated code is trying to get text from the global  ^%qCacheMsg("%Utility","en",node) = text -- from a node that doesn't exist.

Of course,

Hi,

I have a UrlMap like the one below.

<Route Url="/Results/:queryID" Method="POST" Call="QueryResults"/>

What if I have to pass two parameters to QueryResults, how to do configure Url?

Something like Url="/Results/:queryID/:parameter2"   ?

Thanks.

I have a query text that I need to execute and return results as xml.

It may be an SQL query or an MDX query. Is there some easy way to determine which one is it?

Any ideas?

Hi all,

We faced a problem where we would like to map a $lb object to its corresponding data model structure in order to later on export it as JSON.

So imagin that we have something like this that actually maps to a persistent table with its structure. 

$lb("",,,,,"",,,"BOOLEAN","0",2,2,"1",,"bla",$lb(,,"bla","20050502123400"),"",1,"bla",,0)

Is there a way to transform this $lb (without the need of openig the object itself) to a JSON object with the proper table fields as properties?

Many thanks

I wanted to know if there was a way to dynamic set a target in the rule send command. I have a assign property that uses the lookup table that I wanted return the name of the target value and then set the target to that property . When I set the target= _@tDestination there is a parser error.

I set up cache in container, which is working fine. But when accessing managment portal the default user was alway Unknown user and no username or password were required. So i disabled the Unknow user in the Security section, but now i keep getting an error access denid. 

Hi!

I have a global-mapped class that I want to add a transient property through (or at least, not stored on the database). This property is the sum total of various charge classes that are linked to the class via child relationships.

I want this new transient property to be visible at least via SQL.

My current approach is to total it up in a ClassMethod called via SqlComputeCode.
