#Ensemble

Wondering if there is a limit on max number of rules you can have in a single router? For outbound ADT we are approaching 60. From performance standpoint is it worthwhile to create a new router component and the service sending the same inbound message to 2 processes?

I  am reading the following code in ObjectScript:

GitHub repository
 

And there is a sentence which I am facing difficulties to understand:

    kill ^OPNLib.Game.CWLF

I know that kill removes variables, OPNLib.Game are the package and subpackage, and ..World is a property. However what does CWLF mean?

You could think that it is the class' name, but it is:

Class OPNLib.Game.ConwayLifeGame

The class name is ConwayLifeGame

Is CWLF an alias for the class name?

If yes where is it defined?

Hi All,

I am encountered <INVALID OREF> error in one of the components in the namespace as we are processing and generating huge files and sending them to downstream systems. One possible way we tried was to allocate more memory for the namespace in ensemble, but this kind of intermittent error still occurred only if processing the huge files. Also we tried to resend the failed message and the error would be gone. Another possible solution is to kill unused local variables to release memory space.

Hi,

I got the <INVALID OREF> error in the component and the error screenshot as follows:

​​​​​​

When I try to debug in the code, I go to the class and view other code in eclipse and find out the error method. How should I determine which line threw the error according to the error? There is the line number"+8" in zProcessRequest method. Is that the line counted from the method name or below? Looking forward to your reply. Thanks.

Every developer has made the mistake of accidentally leaving temporary debug code in place when they meant to remove it after debugging is complete.  The great thing about writing in ObjectScript is that there is a way to make temporary code be truly temporary and automatically self-destruct!   This can also be done in such a way that the code has no change of making it into your source control stream, which can be helpful as well.

The secret to this lies in making use of the "Intermediate code" (.INT) which is generated when you compile classes (.CLS), routine code (.MAC) or CSP pages (.CSP).

Hi All, I'm in the process of trying to rollout the git version control system with our current code base within Atelier.  We use Ensemble to develop interfaces but are looking to move to IRIS in the near future.  Our code is structured similar to below:

My initial thoughts are that we would have three repositories.  One for DEV, TEST and PROD.

When compiling in 2018.1.2 using $system.OBJ.CompileAllNamespaces() I am seeing the following errors on some of our Record Maps.

ERROR #5496: Inverse property, 'osuwmc.RQIRecordOut.Record:%ParentBatch', is not defined, 'RQIRecordOut.Record:Records'
ERROR #5496: Inverse property, 'osuwmc.RQIRecordIn.Record:%ParentBatch', is not defined, 'User.RQIRecordIn:Records'

I am using Ensemble FTP adapter to monitor file directory for files that require SFTP transfer to remote server using public/private keys for remote server authentication.

This works great in my engineering development space where file protections are loose.

I want to apply "principle of least privilege" regarding the public and private key files specified in  FTP Outbound adapter Business Operation. 

Can anyone recommend (Linux) permissions that allow Ensemble to execute the SFTP operation but minimizing access to the key files?

I've tried variouse combinations without success.

Looking for pointers on how to create a file operation class that would use the HL7 Message Type in the file name

For example if the Message type was ADT^A31 the file name would be ZLOG_FILE_ADTA31_20190927.dat

Thank you for looking.

Is there any issue with setting the Pool Size > 1 on components using EnsLib.FTP.PassThroughOperation? I have a component that has 60,000 documents in the queue and looking for way to process this output quicker.

How do I manipulate a string in Ensemble DTL (X12 document) to extract a string starting from the right, or end, of the string?

I need to have 10 digit phone numbers, however some of the source data records include the "1" for the long distance dialing and I need to exclude this.

I have tried using Right(), SubStr(), and even SubString(string,*,-10) but it will not compile.

I find it hard to believe that Ensemble does not have the ability to read a string from the right. 

Thank you for any assistance.

A permanent job opportunity has arisen for a Caché/Ensemble developer with at least 5 years experience. My client is a specialist resource provisioner of developers for high profile clients in the finance,  healthcare, retail, distribution and credit business that are mainly based in central London. My client is looking for a highly-motivated individual who thrives in an environment where problems are open-ended.

Good morning -

I am attempting to pass some HL7 content (say, a complete ADT message) from one server to another via REST/JSON - for reasons. 

I can get the data across but when I try to create an EnsLib.HL7.Message object from the message in the JSON body, I end up with just the start of an HL7 msg in the resulting object. Looks like: MSH|^~\&

The start of the code accepting the data looks like this:

S tReq = {}.%FromJSON(%request.Content.Read())
S tInput = tReq.Message

S tMsg = ##class(EnsLib.HL7.Message).%New()
D tMsg.ImportFromString(tInput)
S tMsg.DocType = "2.3.

Greetings,

I am trying to test an hl7 message inside studio and when I click on the test button I get this error:

"<FUNCTION>GetProp+2^%CDCalBk"  at  9:51 am.   $I=/dev/null:50333010   ($X=0  $Y=54) $J=50333010  $ZA=0   $ZB=""   $ZS=65536 ($S=66023400)

I have never seen this before! Any suggestions?

Here a simple test message:

MSH|^~\&|TESTRAD|ABC|RADIOLOGY|WYZ|20190715125605||ORU^R01|20190715125605|T|2.3

Hi all,

is it possible to omit the typical XML header line

when writing an the contents of a EnsLib.EDI.XML.Document  using the above mentioned operation. I´ve already digged into the config value Format. It only states that:

C(e) : output an XML header line declaring character encoding e. If e is empty use the encoding defined by the Adapter. If e begins with ! force the output stream's encoding.

I am trying to return a stream soap response using web services I can call my web service supply it with a xml string which works fine . I then work on that XML and try to return  a Stream but all works in the production when my service receives the stream after I get the error  as if its trying to copy stream to a variable and I am confused as to where that operation happens.

The errors I am getting 
ERROR <Ens>ErrException: <METHOD DOES NOT EXIST>zCopyFrom+28^%Stream.TmpCharacter.1 *Rewind

and here is the stack trace in case I am missing something

• $$^zGetErrorTrace+3^Ens.Util.Trace.

We have a case where we have 1 message coming in, but then sending two messages out to the same location. Even with FIFO sometimes the messages get out of sequence depending on what is need to be done to the message in the DTL before send. Is it possible to call sleep or Halt or write some kind of a function to put a pause in a routing rule between two sends?

I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.

When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:

#5002: Cache error: <PROTECT>%LoadData+7^EnsLib.HL7.Message.1

Tracing that back to the source, I find:

Lock +(^EnsLib.H.

InterSystems has corrected a defect in applications that use Unicode character 223 (ß). This defect can result in incomplete query results, class compilation errors, and removal of custom SQL privileges.

This problem occurs on systems that are running or have previously run on:

• Caché and Ensemble 2018.1.0, 2018.1.1, and 2018.1.2
• HealthShare Health Connect (HSAP) 15.032 on Core versions 2018.1.0, 2018.1.1, and 2018.1.2
• HealthShare Health Connect 2019.1
• InterSystems IRIS data platform – all currently released versions
• InterSystems IRIS for Health – all currently released versions

The defect is triggered by data and component names containing Unicode character 223 (ß). In the versions listed above, an uppercase conversion incorrectly maps that character to Unicode character 7838 (ẞ).  Applications perform this uppercase conversion using features such as $ZCONVERT and %SQLUPPER.

Problems can occur when accessing data or classes created or modified on a product with a different uppercase conversion than the one currently in use.

InterSystems has corrected a defect that could lead to invalid backups on Windows platforms. The defect causes upgrades to disable the EnableVSSBackup setting. By default, EnableVSSBackup is enabled (value set to 1) and the upgrade sets its value to 0. Windows VSS backups taken with this setting disabled may contain invalid CACHE.DAT files.

This problem is limited to Windows platforms on the following versions:

• Caché and Ensemble 2018.1.0, 2018.1.1, and 2018.1.2
• HealthShare Health Connect (HSAP) 15.032 on Core versions 2018.1.0, 2018.1.1, and 2018.1.2
• HealthShare 2019.1 (Unified Care Record, Patient Index, Health Insight, Personal Community, and Provider Directory) on Core version 2018.1.2
• HealthShare 2018.1 (Information Exchange, Patient Index, Health Insight, and Personal Community) on Core versions 2018.1.1 or 2018.1.0

The defect only occurs if you are upgrading to a version listed above. Once you have upgraded to an affected version, you must manually enable the setting; otherwise, it will be disabled on future upgrades, even when upgrading to versions containing the correction.

For customers using Windows VSS backups, InterSystems recommends enabling this setting on any 2018.1 instances of Caché or Ensemble. Once you have enabled the setting, future upgrades (including to affected versions) will preserve its value.

Is the TotalDuration column (processing times for all messages w/in a time frame) measured in seconds?

Thanks,
LG

Hi,

I'm trying to run a query from Management Portal, to get a count of messages in 10 minute periods for analysis. I'm using DATEPART to pull the hour and minute portions, but the value being returned is the UTC value, rather than the actual value.

i.e.

TimeCreated = '2019-09-10 23:01:45'

DATEPART(hh, TimeCreated)   is returning 22 rather than 23. 

How do i force DATEPART to return the correct display value?

This article will provide tips and tricks on customizing Ensemble business hosts with configurable settings.

Ensemble production Settings are configurable values that control the behavior of a production and its hosts.

The documentation for adding and removing Settings and specifying categories and controls for Settings is provided at the link:

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=EGDV_prog#EGDV_prog_settings

Can health Connect create a file in a directory, than add data  (HL7 messages) to it?

Is it possible to create a task that will initiate a Business Service that is dependent on the completion of a separate EDI data process?

I have a complex data flow with multiple EDI processes where one process must run and produce one or more files that get deposited in the source folder for the next EDI process.  The entire process is currently set up where 2 of the EDI processes execute at a specific time.  The problem with that is when a network or server interruption occurs at the time they are supposed to start, it causes a complete failure of the entire process.

After upgrading I ran a $SYSTEM.OBJ.CompileAllNamespaces("u"). What I got in return was kind of a shock.

In reviewing errors I am seeing code being referenced but no longer applies. It is referring to stuff that might of been defined in the Context , Formal Spec ,Thread , etc.

ERROR #5373: Class 'osuwmc.CPD.DataStructures.TblPharmacyDEA', used by 'osuwmc.CPD.BusinessOperation:SelectProviderTempDEA:FormalSpec', does not exist

Trying to modernize tasks I have to do on cache like change global variables on different servers, different namespaces....

Actually, I have a bash script  doing ssh on each server and running bash  script on each server like this

echo "zn \"namespace\"
s ^Var=1
"|csession ensapp

But this is not clean/modular/. I was thinking about using Ansible - as it is exactly what I need to do all the git pull. But I am not sure how to interact with cache. A shell ansible module - no way as it does not manage state.

We have a customer that is not able to accept HL7 result messages that are missing OBX:3.1. I have been trying to create a function that could return a boolean value of 0 if the message didn't meet the expectations of the function.

ClassMethod IsValued(pHL7Msg As EnsLib.HL7.Message, pSegment As %String, pField As %String) As %Boolean
{
            #dim tSeg as EnsLib.HL7.Segment
            
            set tSegCount = pHL7Msg.

I have several BPL's that act like SQL Server Integration Services (SSIS) where they are transferring data. When I do this they are all being written under 1 session id, is it possible to make the BPL create multiple session ID's as it is cycling through a Snapshot, so it is easier to read in the trace?

Thanks

Scott Roth
