Hi, Community! 

This week we have two videos. Check all new  session recordings from Global Summit 2017:

I am confused about the meaning of "rating".

Is it how good the post is?

I did a search on "Rating" and got a lot of hits, but none seems to answer my question, either that or I missed it.

It would be nice to have some basic documentation on questions like these.

I don't mean to be difficult and maybe I don't understand, but what is the reason for having a rating?

Hi, Community Members!

The goal why we are posting questions on Developer Community is to get the answer.

Here is very simple guidelines document on how to ask questions which would get answers.

When you post a question you need to feel 3 fields: title, body, and group. And tags.

1. The Title

A good title should contain the brief description of your problem - it should not be longer than 80-90 symbols.

But brief doesn't mean one word. These are not very good titles for questions: Cache, Ensemble, Peace, World.

Hi,

We are having a problem where sometimes a websocket connection started from a CSP page does not share the same SessionId as the CSP page itself. We are also using ECP and can see that both sessions are often even on different application servers.

Trying to connect Ensemble to RabbitMQ following this article I'm using Java Gateway and encountered the following problem - in all my calls I need to pass connection object, which is always the same but it takes a long time to create. Here's java code:

package com.myorgname.rabbitmq;

import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.

Hello!
We want an Integration that should be moving files from a FTP server in a DMZ zone into another FTP server on our local network.
I tried using EnsLib.FTP.PassthroughService(EnsLib.FTP.InboundAdapter, EnsLib.FTP.OutboundAdapter)
Using this approach ensamble write data to the database, causing the CACHE.DAT to grow for every file that is moved.
Looks like the entire file is written to the database, is this the case?
We are not really interested in storing any file content information in ensamble in this particular case.

I have a class that has a list property, which contains a list of other objects, and I want to join against it in SQL.

Class Foo Extends %Persistent
{
Property MyBars As list Of Bar;
}

Class Bar Extends %Persistent { Property Name As %String; }

Simply querying the Foo table, I see that MyBars looks like a $LIST, so I tried using a query with the %inlist operator but that didn't seem to work as expected. The following query produces zero results:

select bar.name from foo join bar on bar.id %INLIST MyBars

Is there some convenient way to do this sort of join?

I have implemented a csv record mapper to read files into the production in ensemble but it errors every time I read a file with headers on the columns as these are not recognised as the specified data types .Is there a way to ignore the headers when reading in values from a file with headers. Please note this have been built using the pre built components.

Hello,

we have to implement some application logic using either Java or .NET. Which should we choose? Given that all other considerations are equal, which is in your experience better way performance-wise to interact with external components in Caché: .NET Gateway or Java Gateway?

Thanks.

Hi

Reading through the installation guide I found a fairly stern warning in the robustness checklist not to use the inbuilt apache web server.

>Use a robust web server. Do not use the limited Apache server installed with
>Ensemble. It is provided as a convenience for use on development systems and
> is not a fully capable web server.

We only have a few users, the Interface team (3), an integration consultant(1) and an interface monitoring/development vendor.

Do we need a 'robust web server' for using HealthShare Health Connect Integration engine?

Hi

Please can someone send me an example of how to auto refresh a table pane. 

Thanks

Hi-

I have an IP address (or hostname) and a port (in this case a super server port #) and I want to try to verify that network communications can be established between the host I'm on and the given hostname and port number of a remote server.

Is there any way pragmatically to do this within Cache?

Hi

We have a need in our Ensemble production to take HL7 ver 2.3 and provide an XML representation of it to provide to non-HL7 consumers.

What would be the prefereed way to do it.

Are there are pre-defined XML schemas in Ensemble that could be use ?

We are currently on Ensemble 2015.2

I am trying connect DB using Oracle DB link (ODBC).  I am getting the following error. Please help me fixing this error.

I am using Oracle 12 c.

Thanks,

Hi, folks!

Is there any way to use $CASE or $SELECT functionality in SQL SELECT query?

E.g. something like this:

SELECT product, $CASE(status,"New":field1,"Payed":field2) as data from sales

To see either in data column either field1 or field2 values in regard of status value.

Hi-

I am running the latest version of Cache and am trying to use the Config.* classes in the %SYS namespace to be able to gather information from a cache.cpf file that was provided to me by a customer.  The customer is running an older version of Cache which had a different Version number in the cpf file.  Theirs is 2013.1 and mine is 2015.1.  

My question is, are the Config.* classes backwards compatible.  Can I use a 2017.1 version of Cache to read information from cpf file from a 2014 system?

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports.  We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down.  We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page.  I am new to Cache so any help would be greatly appreciated.

Also, is there an easier solution to this print all problem?

I have a SOAP Business Operation that will to alert when the EMR returns NACK but I don't want to stop file flow? I would just like ENS.Alert to send out the email and then move onto the next message and not to stop the BS or the BO. Is that a setting in the BO?

Hi there.

I was wondering if there was a supported way of editing the Title bar of the management portal so that at a glance it is clear as to what environment is being worked on. This would be in addition to the namespace and server name being displayed.

Ideally I would like to make it clear at a glance that a user is working within the Dev or Live environment.

Hello,

I am looking for ObjectScript implementation of crypt-compatible function, that generates md5 salted hashes (output is in the form of $1$salt$hash). From what I understand it uses its own spin on md5 algorithm:

https://en.wikipedia.org/wiki/Crypt_(C)
http://php.net/manual/en/function.crypt.php
http://www.gnu.org/software/libc/manual/html_node/crypt.html

Does Cache have something like that built in?

Has somebody here seen it implemented somewhere?

Thanks.

Added:

I have found description of the underlying algorithm here: https://www.vidarholen.net/contents/blog/?p=32

If you are facing out the license expire warning message on your terminal ("*** Warning: This Cache license will expire in 3 days ***") and you do not want that message to be displayed, you can disable/enable that by rinning the following commands:

Do ExpirationMessageOff^%SYS.LICENSE - Disable

Do ExpirationMessageOn^%SYS.LICENSE - Enable

Hi, Community! 

This week we have two videos. Check all new videos on InterSystems Developers YouTube Channel:

1. What is InterSystems Cloud Manager?

This video provides an introduction to InterSystems Cloud Manager (ICM) and its capabilities.

Hi, folks!

When you deploy DeepSee solutions you often do not want grant a User  %All Role to work with a particular Dashboard.

Consider a Dashboard 'Dash' with a few widgets where listings are being used.

If you manage a Role to get access to the Dash you need to grant access to %DB_DBNAME resource to have a database access,  grant access to a Dashboard resource (if any) and ...  grant SELECT accesses to all the tables involved in SQL queries being used in all the listings of widgets.

And every

I need to create a standards document for new developers who are coming to Cache from other backgrounds.

Does anyone have an in-house document they could share with me?

Regards

Mike

Hi, Community!

Consider I have ResourceA which is used by role RoleA in dev environment and want to deploy it with the solution on a target system.

Would you please share the best practices to make it?

Thank you in advance!

Has anybody devised a process that would allow the render and printing of BPL diagrams created in Studio? Thank you.

Hoping someone can help.

I had posted a similar question outside this group a while ago "Errors requesting data from local Ensemble FHIR Repository" but haven't had the chance to follow up on it since. It was suggested I re-post inside this group.

I'm trying to request data from my local FHIR repository using a simple JavaScript client and am getting the following CORS errors . ( It is a standalone client not inside HealthShare without CSP etc. on my localhost ).

Hello again and welcome to the Part 3 - Using the SQL API!
If you have been wondering about how to use SQL along with Frontier, you came to the right place. That's because since Frontier wraps the common Caché SQL API within it's own, you need to use the API provided from it. But you don't need  to worry about its learning curve, because the Frontier SQL API is really simple.
If you arrived here without checking the Part 1, I'd recommend you doing so, because Part 1 covers the essential for getting started with Frontier routers.
