Hi everyone

I am new to the bpl diagram. I would like to add an if statement that checks whatever an object is null or not.

I guess that: condition='response.Content != null' would not be ok...

<if name='CheckObj' condition='response.Content != null' xpos='200' ypos='1700' xend='277' yend='2197' >

I tried to search for this information in the documentation but I didn't find any help.

Do you have any suggestions?

Thanks and best regards

Query Response from MSSQL

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

We would need to know the Ens.Response SourceConfigName to identify which Operation has raised an exception.

We have tried:

$$$LOGINFO("..%Process.%PrimaryResponseHeader.SourceConfigName..: "_..%Process.%PrimaryResponseHeader.SourceConfigName) //It outputs an empty string
$$$LOGINFO("response.SourceConfigName: "_response.SourceConfigName) //It generates an exception


We would need to get from an Ens.Response which body is null, its SourceConfigName:

Sign and verify in SMIME format

In some project, I found the need to use SMIME format https://www.ietf.org/rfc/rfc3851.txt, basically is an standard used to wrap a message together with its signature using a certificate (usually X509). Ensemble don't have a single class to do that but inside the Ensemble installation we have the openssl utility, so in this example I use the "openssl smime" command to sign or verify a message.

The example has two Business Process that able to sign or verify and in order to test I made a simple production.

Hope this helps

I have a process in which i call a rest operation in a while loop, get a response in JSON format of 50 issues, with paging, meaning this call will happen until the total amount of issues will be returned. each JSON is parsed into a proxyObject, and inserted to a list. later the entire list will be sent to an SQL operation which will write the data in the appropriate tables.

I'm trying to get a text value of a xml node of a XML Document through the xpath activity within a BPL diagram.

I set the source to Request and all the other properties.

The error I always get back is Method does not exist...

Could anyone help me out?

Kind Regards

I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR.  I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..

Did anyone run into this error when stopping a Production from Ens.Director?

Ens.Director::StopProduction => ERROR <Ens>ErrProductionNotQuiescent: IRIS can not become quiescent

It happens sporadically when an automated unit test from a class that extends %UnitTest.TestProduction runs a test on a Business Process. I already increased the parameter MAXWAIT to 30 seconds, but the error still happens.

After cloning "http://github.com/intersystems/Samples-Integration-RedLights" sample code I imported sample production from /home/project/Samples-Integration-RedLights/data/EndStateProduction.xml file to my local system.

Now I am getting the error "ERROR #5021: Directory '\home\project\shared\Samples-Integration-RedLights\data\SampleFiles\' does not exist." in my service.  

While modifying the Directory path I am getting below error :

Presenter: Mark Massias
Task: Present complete, contextualized information to the people who must act as part of a (mostly) automated business process
Approach: Give examples of using InterSystems’ workflow engine.

More and more business processes are automated, but sometimes a person needs to make a decision. In some cases policies require an individual to approve an expenditure, or when loading data a person needs to sort out exceptions where the data in not clear. This session explains how to include people in business processes in a way that presents the user with a complete context for the decision they have to make.

I'm looking for a way to get the message header ID for the current message in a Request to a Business Process.

I've located some code that gives me what I need, but it runs the risk of violating the "abstraction layer" ISC has in place around such things. And while I very much appreciate their efforts at keeping things simple for me ... well, sometimes you just have to dig through the guts to get what you want.

Is there a documented, deprecation-resistant method for getting at %Ensemble("%Process").%PrimaryRequestHeader.%Id() from within a  BP?

In a Business Process (BPL) I noticed that if I 'm using a "scope" to handle errors  then inside the "scope" when a "call" is used, the "request" and "response" action (i.e set for callrequest.prop = request.prop & response.prop = callrespones.prop does NOT work !
The result is that the values of those properties in the callrequest  are nulls (I do see the properties names in the content of the callrequest message)

I have a BPL Business process which always processes messages - mainly it waits for responses since downstream systems are seriously async.

I need to update this process.

Wwould the existing instances of this Business Process complete correctly after the update?

My BPL changes would result in:

  1. New S method in the Thread class
  2. New OnResponse method in the context class

Both changes are in the middle of the process, so there are S/OnResponse methods before and after my change.
