Question Scott Beeson · Apr 27, 2016

I have two servers in our TEST environment.  One with HSBUS and one with HSREGISTRY.  Let's call them "HSBUS01" and "HSDB01" respectively.

Now, I can access HSBUS with my SQL client by using the JDBC driver pointed to hsbus01.full.name.com and port 1972 and specifying a namespace of "HSBUS".  I am, however, unable to access the HSREGISTRY instance via SQL with a similar combination of information.

I have access to the web interface on both servers (/csp/sys/#CSP.Portal.Home.zen). What screen can I use to compare the relevant settings? I think it might be a port issue.

Question Andy Caranicas · Apr 27, 2016

We have a query that looks something like:

select a, b, c, d, e, f

from tbla inner join tblb on tbla.....

This query runs in the expected 200-400 ms range.

If we run the same query but reduce the select to just:

select a

from tbla inner join tblb on tbla.....

then the query runs for 30 minutes or more. 

The rest of the query is identical.  Is there a logical explanation for how this can happen?

Thanks.

I have to disect thousands upon thousands of strings like this:

96842-2-AEV.00001-63561-001958-100728760I-42

I've been able to pull out the first, second and final segments as separated by hyphens, but now I have a predicament where I need to use the second segment, the 2 shown in the example above, in a join to another table.  Problem is Cache apparently doesn't like doing that.  Just the same, I have to find a way.

Here's the code I'm using to pull that segment out into as separate field in the query results:

substring(prov_record_id, charindex('-', prov_record_id) +1, charindex('-AEV.',

Hi Community,

How can I create a JSON with the object ID by using the %Object:$toJSON API?

I have the following piece of code bellow where I create an object reference, create a %Object instance from %fromObject and them I am creating the JSON from $toJSON, but it does not expose the %ID (object id). How is the best approach to create a JSON with the respectives object IDs?

Try{Set tPersonObj = ##class(Data.Person).%OpenId(pId)If $Get(%objlasterror) $$$ThrowStatus(%objlasterror) Set tObj = ##class(%Object).$fromObject(tPersonObj)Write tObj.$toJSON()}Catch ex

Question Clayton Lewis · Apr 26, 2016


I'm trying to find a good way to control the Filename for X12 Acknowledgement files, but there doesn't seem to be a way to do that without custom coding.  Here's what I figured out so far:

EnsLib.EDI.X12.Service.FileService allows you to set a Reply Target Config, which would likely be an X12 File Operation.  The Service doesn’t have any settings related to the name of the Acknowledgement file though.  That’s determined entirely by the Operation.

The Operation allows the outbound filename to be derived from the X12 Document’s Source property, by including %f in the File Name spec.

Announcement Stefan Wittmann · Apr 27, 2016

Starting with 2016.2 the Java XEP binding will no longer support the in-memory connection mode. The in-memory mode was deprecated in earlier versions and applications should switch to the TCP/IP connection mode instead.

The TCP/IP connection mode has bridged the gap in performance to a large extent over the past couple of years and enables the Java client to run on a remote machine.

Let me know if you have any questions or concerns.

This is a cross-post from our compatibility blog: http://blog.intersystems.com/compatibility/2016/04/22/removal-of-in-mem…

Question Steve Pisani · Apr 19, 2016

Starting off with a working REST interface, I can access the CSP Application definition screen for the application  (System > Security Management > Web Applications > Edit Web Application), and "turn off" the application by clearing the Enabled: [ x ] Application checkbox. From then on my REST calls return an HTTP 404 error. (That's expected).

However - one expects that re-enabling the Application in the CSP Application screen, would return my REST services to a working state, however, this is not happening.  All REST requests continue to return an HTTP 404 error.

(Possibly?) little-known fact: It's possible to use $ListBuild on the left hand side of the equals sign in a set command to extract multiple list values at once:

set $ListBuild(several,individual,variables) = list

For example:

USER>kill
 
USER>set colors = $ListBuild("red","orange","yellow")
 
USER>set $ListBuild(r,o,y) = colors
 
USER>write r,!,o,!,y,!
red
orange
yellow

See for reference: http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls…

This feature was news to me - I use $ListBuild lists a lot but hadn't come across it until today.

Hi,

I'm posting this for the benefit of others. Not often one changes certificates in Cache, at least in my case. I run a system, that uses certificates to encrypt SOAP messages, and since the last time I ran it, my certificates expired.

So I renewed them using our PKI tool, so far so good. I gave all (3) certificates the same names (and filenames too) as to those expired, thinking that everything would just work fine next time I call the SOAP service.

Unfortunately, I got trapped.

It took me a rather longer while to realize that replacing old files with new ones is not enough.

I just recently got a mail regarding the latest and greatest.

I find the mail impossible to read or make any sense of.

At the bottom it says to manage my subscription.

I clicked on the link and it took me to a page that says I am denied.

All the time I am still logged in.

Then, can you tell me how do I manage my subscriptions and stop those impossible emails?

I sure wish we were back to the Google Group, I understood that.

Introduction

If you manage multiple Caché instances across several servers, you may want to be able to execute arbitrary code from one Caché instance on another. System administrators and technical support specialists may also want to run arbitrary code on remote Caché servers. To address these needs, I have developed a special tool called RCE.
In this article, we will discuss what are the typical ways of solving similar tasks and how RCE (Remote Code Execution) can help.

What possible approaches are available?

Question Orion Correa · Apr 21, 2016

I've been using iFind indices in one of my applications but this morning discovered that the index is missing data. I confirmed the issue also exists in our test environment and rebuilt the indices there. That seems to have fixed the immediate problem. However I'd like to understand how this came about to avoid it happening in the future.

Has anyone encountered this before and know the cause?

We've regularly upgraded the Ensemble instance when new releases come out and are now on 2016.1. We've been using the indices for just over a year without issue except that sometimes this error comes up:

Hi! 

There is a question for Ensemble on Stackoverflow:

I have the below dtl. In the foreach loop, I am just copying the same code in another part under anif condition. How can I avoid this redundancy? Can I reuse using sub transformation?

Here is the dtl class file :https://docs.google.com/document/d/1snJXElyw13hAfb8Lmg5IaySc7md_DE8J40FB79hBaXU/edit?usp=sharing

Good afternoon, I have image files stored on disk. I would like to display those images in an <image> control as the end user clicks on rows in a tablepane. I already do this with image data stored in a cache database:

s imageComp = %page.%GetComponentById("ImgTab"_tLdCnt)
s imageComp.disabled=0
s tId=rsId.Get("ID")
s tPageObj=##class(My.PageObj).%OpenId(tId)
s oid=tPageObj.ImageBLOB.%Oid()
s encryptedOid=..Encrypt(oid)
s imageComp.src="%25CSP.StreamServer.cls?STREAMOID="_encryptedOid

In this project, I can displayed the image if I set the scrDisabled, scrMissing or src attributes to the full path

Hi this is my first post, so a little about my background. I've been programming in PHP/JavaScript for about 10 years.  
I've got quite a bit of knowledge surrounding object orientated programming and know the basics.

Last year I looked into the Mirth integration engine and did some work around that.

I've now moved jobs and I'm doing some work (surprise, surprise) with Ensemble.

I've done the tutorial and understand the basics of the web 'frontend' and what an integration engine can do.

Question Jeffrey Semmens · Apr 20, 2016

It looks like the normal usage of calling an Ensemble based Web Service via Ensemble is to create an Ensemble Business service that inherits from EnsLib.SOAP.Service which is then used to call a business operation which inherits from EnsLib.SOAP.Operation and the SOAP Outbound Adapter which can be generated via the SOAP wizard.

But, what if you don't want the extra step of calling the web service class via the operation?Has anyone actually constructed the Business Service to directly invoke the web service class?

I tried logging into https://beta.learning.intersystems.com to view a video.  My browser auto filled the login form.  The username, the same one I use here and on many other ISC sites, is "sbeeson_MHCX".  Now I have a message that says "Only lowercase letters allowed" and any time I visit the login form it just shows the same message.  I cannot get back to the form.

I could obviously use an incognito window or clear my cache, but this needs to be fixed.

The following situation always catches out new Ensemble users, and is likely to continue doing this until it is addressed..

A business operation, service or other host that is configured with a dedicated # of actors, (ie, not using the actor pool) runs with the version of compiled code that existed when the host was started.  This code is loaded in memory. 

Whilst they are running and developers edit and compile lines of code for a business operation, they expect immediate effect, but this does not occur for the aforementioned items, and the only clue that given is an Information event log

Hello,

In my project, I am calling a store proc on third party database. I am using SQL Gateway and ODBC. Everything is working fine until the store proc changed.  In store proc they have changed the return alias name for a column. In Ensemble Snapshot I am not seeing the modified alias name until I restarted the whole Healthshare instance.

Here is my question, is there any other way? We do not want  to take the instance down if it happens after we go live.

Does Caché support SQL CREATE SEQUENCE as in PostgreSQL?

If not, what would be the best alternative? Create my own sequence logic as the example bellow?

{


Property dummy As %String;

Property myvalue As %Integer [ Calculated, SqlComputeCode = { Set 
{myvalue}=##class(Util.MySequence).CurrentValue()}, SqlComputed ];

ClassMethod CurrentValue() As %Integer

Greetings.

I'm currently struggling with launching a routine from the command prompt using ccontrol.

Basically I have a routine with a parameter which works fine using the following:
ccontrol cterminal ^ANDYTST(\"c:\temp\\\") USER

This receives c:\temp\ then in the routine.
However, when there is a space inside the parameter it assumes that it receives a script.
I can still run it using ccontrol terminal, but that then tells me the argument is invalid.
Therefore, is there something like a placeholder for whitespaces?
And, is it possible to hand it the credentials?
Or is there a better way to launch a
