#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.

Is it possible to dynamically adjust the RetryInterval andFailureTimeout settings in a BPL?

I've got a business process that calls a web service operation to get a session ID from an external system. There is a string property returned in the body of the response that indicate an exception occurred in the external system. I have code in the BPL that examines the property and sets the status property to an error status when that occurs.

Recordmap within a BPL

I have a text file that is fixed width delimited and am using a BPL to process this file, ultimately performing a transform from the text file to an HL7 message. I created a DTL, mapping from the recordmap to the HL7. In my BPL, I am performing some loops and other logic (that all is working). My issue is what to do when I perform the Transform.

maybe I am not looking in the correct spots, but how should one handle an Exception from a SOAP web service within the Business Process Language? For example I am sending a request to a Web Service to try to get information, but the response I am getting is an Exception like "Patient Not Found".

Is there a function I can call to check the response similar to what I do to check a SQL Snapshot to see if it is valued?

Thanks

I need to set and use some context variables in a transformation (written in DTL), but the code is manually written.

When writing the same as BPL I define context variables and they are visible in transformations called by that process.

In something like this my.DTLtransform sets HL7 message fields to values in context variables:

Using Snapshots in BPL

I have a scenario where I am calling a business operation which populates and returns an EnsLib.SQL.Snapshot via dynamic SQL to a Business Process. I then want to iterate over this snapshot and call a RecordMap Operation to write those records to a delimited file.

Is this the correct way to do something like this? If so, does anyone have a sample which illustrates its correct usage?

When the snapshot is returned I save it into a context variable with:

set context.Snapshot=callresponse where the pOutput variable of the operation is set to EnsLib.SQL.Snapshot.

Hi,

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 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..

Does anyone know how to disable the auto-refresh in Healthshare, especially for Message viewer , Business process designer, DTL editor pages?

These pages in management portal refresh every 15min( i.e. as per the session time out setting) . I tried to set the following two configs to disable the auto refresh but both had no impact. 

set ^EnsPortal("DisableInactivityTimeout","Portal") = 1
set ^%SYS("Portal","EnableAutoRefresh") = 1

Thank you for your help.

I installed Atelier on Windows in order to take a look at how the BPL and DTL graphical editors accessible via the "Open diagram editor" action work. The diagram editor is opened but I get the following error:


Message from webpage
---------------------------
Unable to load SVG diagram. Please ensure your browser is supported for portal access.

It looks like Atelier uses IE in order to display the editor even though my Windows default browser is Chrome.

I'm looking at an issue where I need to grab an ID number from an external SQL table when it doesn't exist in a HL7 message, and then add it to the HL7 message.

I have built the logic within a BPL which checks for the lack of ID, and then pulls the ID from the SQL table (and storing its value using the context functionality within the BPL) however I am at a loss as to how I then take the ID and add it to the HL7 message before passing it to a router.

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

Hello,

We have defined four BPL Business Processes. One gets occasionally errors when pool size is two. No errors happen with pool size one. The error happens on calling %Save() on a large objects with many references to other objects.

Error #5803: Failed to acquire exclusive lock on instance of 'classname'.

Error #5002: Cache error: <ROLLFAIL> %TRollBack+10^%occTransaction

The error happens on a particular large object.

Our FileService gets the same Errors #5803 and #5002 with class 'EnsLib.EDI.X12.Document'

Hello,

I want to process more requests per second in Ensemble 2015 (soap service). My problem is in a business process that makes a great transformation. I thought that I can put its group size to 4 (the current value is 1), or put 4 business processes and apply, for example, the round-robin algorithm.
Which alternative is better?

Hi all,

For special definition of the company, we need to define a PoolSize according to the environment that the "Ensemble" is working.

So the first try as been add the parameter into "System Default Setting"

However, this parameter is not available in "Setting default values" in Setting tab.

I've opened the code of my production and I've noted that this parameter is a attribute of the XML element of this item

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.

Limit to Ensemble queues

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.

Hello,

We have a BPL that returns in Response several %Strings, Dates. When we try to add Array of Objects property to the Response we verified just before the BPL terminates the response object has correct values in all properties including the array. We checked the Count(). It appears that even array of String works correctly but we prefer to pass objects rather than strings.
