#Business Process (BPL)

5

InterSystems Ensemble Business Process Language (BPL) is a language used to describe executable business processes within a standard XML document.

Documentation.

I'm creating a Business Process that:

  1. Transforms one object into another using DTL
  2. Sends this object to an operation
  3. Transform the object obtained in first point into another one using DTL
  4. Sends the second object to an operation

The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.

I have tried to make transformation before making CALL's, I mean:

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

I am creating a BPL using the Management Portal instead of creating a custom class.

As per the documentations 'request object' contains properties those were in the original request message object or primary request and can be reference using the dot syntax.

So if the primary request was an HL7 message, i should be able to pull the value MSH:9.2 as follow

request.{MSH:9.2} and assign it to a context property

Is there a way to have a context property be available across 2 or 3 different business processes? For example if I am setting a value in a context property within one business process and want to use the same context property in a second business process, is this possible? Is this something that can be done with the "Context Superclass"?

Hi! I am working on a project where I use record map to transform a flat file and split it into two output text file and in the future will need to split four output files.

I only want to use one target business operations instead of multiple. Is there a way to set the output file and the target folder path in my business process class?

Any advice on how I can achieve this or is this possible? Thanks!

I have a business service that brings in a xml virtual document to the production and also a csv service that brings in a csv file and have a process that transforms both to a xml output but I have a problem with the csv as it is giving me this error when I try to trans form it ```ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zOnRequest+1 ^EnsLib.MsgRouter.VDocRoutingEngine.1 *DocType``` I have read here followed the suggestion but now I do not get any errors but my m

I have a vendor that is sending me an Abbreviation in FT1:16.4.2 that I need to look up against a table to find the correct ID for.

FT1|1|||20180523161501|20180523161503|CG|1906551^Lipid Profile|||1||||||^^^ LAB&06CL|||Z00.00||00410^Knerr^Joel||721410||30100001^Lipid Profile|

But in my Business Process when I refer to request.GetValueAt("FT1:16.4.2") its not recognizing that this field contains information. Is my syntax wrong?

Multiple Threads In Operations

I have a BPL that calls a business service (actually does lots of other things unrelated to my question). We receive an acknowledgement back containing data that is processed in the BPL and sent to the source system. The process of sending to our downstream system "A" and receiving the response takes about 20 seconds per transaction (very slow on system A's side). Due to this slowness, we end up with a backlog close to 1000 messages by the end of the workday.

I have a business process.

if it has an error it dies, or if a have a catch all/fault handler the execution flow goes there.

However, I want another behavior.

If any error occurs I want the process to "Pause" (and alert me), so I can figure out what went wrong and resume from the last request.

Here's an example of how it could work:

  1. If an error is caught, call BO
  2. BO defers response
  3. BO sends alert
  4. Fix BP
  5. Manually resolve deferred response

I'm not set on the exact pause/resume mechanic but I hope it makes the general idea of what I want clear enough. Ideas?

Oracle Transaction

Hi,

I have a question related with EnsLib.SQL.OutboundAdapter adapter.

Is there a way to open an oracle transaction and do either commit or rollback depending on the query result?

Is posible to keep open an oracle transaction to execute a lot of queries on different methods on the same business operation and do a commit when the business process finished?

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?

Thanks

Hi community.

I have an API that is deployed in my production (business service) and it calls to a business process to retrieve the information that is requested.

The problem that I have is that the calls are queued and it's creating a bottleneck

The business process is taking more time than needed.

Is possible to configure the BP to process parallely the requests?

Hello everyone!

I have set up an EnsLib.REST.GenericService with an EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process.

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do :

I have an XML I am sending to an operation from a BPL. This is a query for Patient information from Epic using a web service. I created the operation using the add-in in Studio. I setup the BPL to do a Call and send whatever data I receive from the client. I get a response back from Epic with a list of matching Patients. In the BPL I am trying to use the Response Builder to pass the response ID, name, DOB, etc. to matching context items to then pass to the client as a response. I get the following error within the call:

We are trying to convert some of our SQL Service Integration Service jobs from Visual Studio to Ensemble. If we execute a Stored Procedure within SQL Server Management Studio it is returning approx 12,000 rows. However when Ensemble executes the same Stored Procedure it is only returning 250 rows.

Is there a limitation to EnsLib.SQL.Snapshot?

This is how we are calling the Stored procedure

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.

Hi,

While starting newly created production I am getting below error:

17:14:05.498:Ens.Director: ERROR <Ens>ErrProductionSuspendedMismatch: Production 'Training.NewProduction' was suspended, a new production of a different name can not be started.

Please note that I can start and stop 'Training.NewProduction' successfully but still the status of the Training.NewProduction' is suspended.

Thanks

Hi all,

Does anyone knows if there is a limit per second adding messages to an Ensemble queue? I have a Business Service working and sending async requests to a Business Process, but I can't reach no more than 60-70 messages queued per second.

I've done several tests and same behavior seems to happen with all our productions. So I was wondering if there is a parameter anywhere to maximize the number of requests that can be send to a queue per second.
