Hi, I just installed the TRYCACHE 2016.2.1 preview release into a 16.04 Ubuntu VM.  The install is dirt simple. Very nice. I've installed Eclipse Neon and used your update site link to get Atelier.  Also very simple and nice.  Thank you!

I see there is a January update coming.  Will it be possible to include a license that lets developers launch one terminal session while connected to the TRYCACHE instance via Eclipse?

When I try to do this, I'm exceeding the TRYCACHE license limit.

thanks!

InterSystems Developer Community Birthday!

When an error occurs in your application, simply logging it might be enough. But for certain errors, you might want to send a notification to people right away. There are three ways to generate custom email notifications from InterSystems IRIS.

As stated, I have ZEN report, which I want to render in displayxlsx mode.

Currently it looks like this:

I want it to look like this:

Differences are:

• Bold header
• Cell width fitted to widest row or header

My report definition looks like this:

XData ReportDefinition [ XMLNamespace = "http://www.intersystems.com/zen/report/definition" ]
{
<report xmlns="http://www.intersystems.com/zen/report/definition"
 name="MyReport"
 sql="SELECT TOP 10 Name,DOB,Age FROM Sample.

Hi all (and specifically Eduard L. ;)

The Ensemble Workflow REST API provided here:

https://github.com/intersystems-ru/EnsembleWorkflow

(and mentioned before in this Community, also as the basis of the Angular UI, also available in the same Git) 

Has some very basic documentation as to how to work with the API (which also seems to be possibly a little out-dated as I think the /login URL is deprecated, for example).

Is there somewhere a more comprehensive documentation of this API?

I am trying to create a query that returns the best and worst performing products for a given customer, based on this year's net sales versus last year's net sales, weighted by the total net sales for all of the products sold to this customer in the last two years.

I have created Last Year Net Sales (up to the last month end): AGGREGATE(PERIODSTODATE([Invoice Date].[H1].[YEAR],[Invoice Date].[H1].[Month].[NOW-13]),measures.[Net Sales])

This year Net Sales: AGGREGATE(PERIODSTODATE([Invoice Date].[H1].[YEAR],[Invoice Date].[H1].[Month].[NOW-1]),measures.

Ansible helped me solve the problem of quickly deploying Caché and application components for Data Platforms benchmarks. You can use the same tools and methodology for standing up your test labs, training systems, development or other environments. If you deploy applications at customer sites you could automate much of the deployment and ensure that system, Caché and your application are configured to your applications best practice standards.

I want to generate a list object of routines from the ^$ROUTINE global without directly reading the [^$ROUTINE] global.

E.G. I want to create an array/variable/object with names of all routines that start with "ABC" so that an application process can use each routine name as input for a subsequent process.

Hi guys.

Do You known If Caché has suport to Common Table Expressions (With queries)

By example: https://www.postgresql.org/docs/9.6/static/queries-with.html

I use DataGrip (JDBC client) to query Caché server via JDBC.

The problem I encountered, is that if I wait 10 or more minutes between queries I get an error:

[08S01][461] Communication link failure: Socket closed

To fix that I need to disconnect and connect to server again. Is there a JDBC timeout setting somewhere I can change?

Currently, namespace Alpha is configured to use database AlphaDB as its global database. How would we go about having namespace Alpha configured to use database AlphaDB for its global database except where global ^Customers(CustomerId) has a CustomerId greater than 10M, which we would like to have it redirected to database BetaDB.

In other words, ^|"AlphaDB"|Customers contains all customers between 1 and 10,000,000; and ^|"BetaDB"|Customers contains all customers greater than 10,000,000. Any help would be appreciated.

Hello,

I read the Cache Documentation where it describes Private Property as below:

 Hello,

I have a question regarding Data Connector cube.

I've been asked to annotate a PDF file (in Intersystems Cache).  That is, take in an existing PDF (printable form with areas for people to write in) and use Cache to update it (automatically fill the fields in).

Does Zen have the ability to set a starting/initial PDF?  I see the ability to define an XML format to write in, but that's not exactly what I need, because that will generate my "answers".

I'd like to overlay my "answers" on top of an original PDF.  Do you know how to do that?

Addendum:
After many hours of research, I came across the FOP.

Hi,

I have a Zen Mojo application that haves a tree menu, in this menu I'm loading all records from database (about 1500) and the page is very slow, about 2 seconds to load, I don't know how to get faster.

Hi,

I have 3 classes defined to model the team/team-member/employee relationship, where each employee can belong to multiple teams, each team can have multiple employees, and one and only one team member is a team leader:

Hi All,

I have below schema structure:

base:MSH~{~[~base:PID~[~{~base:NK1~}~]~[~base:PV1~[~base:PV2~]~]~]~{~[~base:ORC~]~base:OBR~[~{~base:NTE~}~]~base:TQS~[~{~[~{~OBX~}~]~[~{~base:NTE~}~]~}~]~}~}

Now there are few cases where source application is sending NTE segment after TQS segment

Is there any way of updating the schema to use the same NTE from OBXgrp, cause we dont want to update the code logic as its happening for few messages only.

I was benchmarking the populate utils when I noticed something strange. Consider this simple benchmarking method:

ClassMethod runBench(count As %Integer = 300000)
{
		s types=["name","ssn","company","title","phone","city","street","zip","mission","state","color","product","string","integer","float"]
		//s types=["name","ssn"]
		s iter=types.%GetIterator()
		while iter.%GetNext(.key,.value){
			s start=$P($ZTS,",",2)
			s opt={}
			s opt.type=value
			for i=1:1:count{
				s res=##class(DataGen.Generator).

Hi, Community!

We have our internal backup system which produces *.cbk files for Full, Incremental and Cumulative backup modes.

Does anyone have an automation procedure to restore this files on some target testing system, check the integrity and mark the files as "restorable"?

Please, share?

Thank you in advance!

Hi Frnds, I am beginner of Cache. I know how to copy from a text file to text file. But i'm facing problem while reading PDF directly using Files concepts. Please provide some solution for copying content from PDF to TXT file.

Thanks

Hi,

I have a ZEN page class with the following annotation. What I try to accomplish is to display data from Object of Type MyPckg.Message. Each Message shall be displayed in a component of type <html>. The outline is somekind the following.

Does anybody else have problems installing the  Caché 2017.1 FT for Win_x64?

I'm getting an error "Unable to execute the required file: The following system error has occurred: The system cannot find the file specified. (2)"

This is happening with the very latest version (build 726) and the previous one ( build 720), whereas the builds before were fine.

I've uninstalled Caché to see whether it was an upgrade vs clean install problem but it makes no difference.

If you have a lot of SQL queries to external systems (or even internal dynamic ones), you can encounter something like this:

Set SQL =    "SELECT "_
                "c.cid                        AS Id,"_
                "c.nid                        AS Nid, "_
                "FROM_UNIXTIME(c.created)     AS Created,"_
                "c.uid                        AS Uid,"_
                "IFNULL(vv.average,0)         AS AvgVote,"_
                "IFNULL(vv.amount,0)          AS VotesAmount,"_
                "body.

To install the Python binding on Windows one must follow the instructions in the following: 

https://blogs.msdn.microsoft.com/pythonengineering/2016/04/11/unable-to…

The reason is that ActiveState Python version 2.7.X is built with Visual Studio 2008 and Microsoft provides Visual Studio 2008, which one must install, so that Python C extensions can be built. 

Also, if one still sees the "error "error: Unable to find vcvarsall.bat" message at the Visual Studio 2008 command prompt, then one needs to do the following: 

pip install --upgrade​ setuptools

Hi, community!

Consider you need to exclude substring(s) from a string.

I did it with the following snippet:

/// excludes all the substrings from the string
ClassMethod ExcludeSubstring(substr,str as %String) As %String

{

 while ($L(str,substr)>1) {

 set str=$Piece(str,substr)_$Piece(str,substr,2,*)

            }

 quit str

}

So, for example:

USER> set str=”ExcludemeGoodstringExcludemeExcludemeGoodstring” w ##class(User.Utils).ExcludeSubstring(“Excludeme”,str)

GoodstringGoodstring

Is this the optimal approach or I reinvented the wheel?

So, I played with row level security and was unable to find a way to get to work it dynamically. I want to determine if the user can access the row in runtime based on a state of external system, but it seems that row level access is calculated during INSERT/UPDATE and stored in %RLI index. Is there a way to achieve runtime access calculation?

As you can see, I got 100% in each section but 75% overall.  There was one I got wrong but then changed.  So either way, there is a disconnect between the breakdown and the total score.

I have posted to aid others in diagnosing problem with SSL/TLS connections to superserver port from .NET client executable.

The cache instance this appeared on is quite old - 2011 - so I do not know if Intersystems have added a better error message in a later version

The actual fault was due to the certificate in the %SuperServer SSL/TLS configuration having expired.

The unhelpful message that appeared in the .NET client included the following partial stack trace.

   *** CacheException.

I want to set the value in the second field of OBX-5, or OBX-5-2. My schema is not broken down to that granular level, so I can't just click OBX-5-2 to populate it. I tried a few variations without success.

target.{PIDgrpgrp().ORCgrp().OBXgrp(1).OBX:ObservationValue(1).2}

target.{PIDgrpgrp().ORCgrp().OBXgrp(1).OBX:ObservationValue(1)(2)}

target.{PIDgrpgrp().ORCgrp().OBXgrp(1).OBX:ObservationValue(1.2)}

Any ideas?
