Folks

1) What's the correct way to check for an existence of a segment? So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:

request.GetValueAt("NTE(1):Description")'=""

Or in a DTL, to see if a Z segment exists:

source.{ZEF:Counter}=1

HL7 segment query using SQL

I'm trying to get a count of specific message type with a specific entry and thought I could build the query in Message Viewer but this does not provide counts (as far as I am aware). So when I take the SQL from 'Show Query' it omits the segment criteria as the code shows below.

I have attached the criteria that has been excluded. Is this possible?

Thank you

I would like to examine the contents of my OBX-5 field and not route the message if it contains alphabetic characters. I've tried various combinations of the Match and Contains functions, with no luck. Should I be using the COS ? operator or plaini regular expressions?

e.g.

OBX-5 Contains "\D"

OBX-5 Contains "?.A"

OBX-5 Contains "[A-Z]"

I wanted to share a little tidbit which is in the Studio documentation (http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls?...) but many people who have been using the InterSystems Studio for a long time missed the addition of this *very* useful feature, and every time I mention this to an audience I see at least one face light up because of how excited they are to learn about it!

Within Studio, the Output pane (View -> Output) is actually misnamed. It is actually an Input/Output window which can be used to run Caché ObjectScript commands!

PDFs and Reading them

I know there are numerous Java libraries available to scan a PDF meta data, but is there a way to scan a PDF using native cache object script? We are looking to take a PDF from an external vendor, scan for meta data, create the HL7 message, and embed the PDF within the HL7 message.

Thanks

In this posting I want to raise the profile of a feature that arrived in 2009.1 but is perhaps not very well known.

It is sometimes useful to make certain packages, globals or routines available to all of your namespaces. Of course you can add the necessary mappings whenever you create a new namespace, but here's a simpler way.

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

We have noticed in the course of the last 18 days our CACHE.dat has grown by 20 GB. Is there a way we can break down the data in CACHE.dat to see what could be growing in size?

Let me state it another way.....Is there a way to see what space an Operation/Service/Process is taking up within a certain Production?

Thanks

Ensemble HTTP OnProcessInput

I am just trying to make a quick hand off HTTP production. I have the class built and compiled onto the server and the production is running as a service. When the production is called (by an inbound job) I can see that the HTTP.InboundAdapter is being used successfully and the stack continues all the up to ProcessInput where OnProcessInput is called in Ens.BusinessService.

Hi,

I was looking at the ENSDEMO namespace in our Ensemble server. In the class Demo.REST.DirectoryOperation, there is a line that uses the macro $$$URLENCODE. I would like to know exactly what does this macro $$$URLENCODE() do. Specifically what value does it. Unfortunately, I can't find anything about this macro in the Ensemble Documentation.

Hello guys,

I want to be able to export a range of messages from my production (from within a specific date interval), but while digging into intersystems documentation, it isn't giving me any details on how to perform this task.

It teases me saying "Ensemble provides a Message Viewer page for HL7. You can use this page to display, transform, and export HL7 messages (either external files or messages from the Ensemble message archives).", but then there are no signs of further information.

%NOLOCK in insert query

I would like to know , if its safe to use %NOLOCK in insert query while doing some parallel processing in Ensemble. We will have pool size of more than 1 for a business process. The business process does an entry in internal meta data table , which will be used for some internal reporting. The same row might get updated by some other process later point of time. i could not produce any error or any issues . Looking forward to hear some opinion on this.

I am having a problem getting pair key authentication to work on my local PC. I am using freeSShd as the SFTP server. I generated private and public keys using putty gen . I used these keys to successfully log into the root directory using both Winscp and Putty. But this is not working with an FTP Operation. Below is the error that results. freeSSHd server log shows that I log in but immediately disconnect.

I am working on HS2015.1.1 Please help !!

Hi,

I have created a Business Service which uses the EnsLib.File.InboundAdapter. This service will call a business service which will create an acknowledgement file in a directory specified in the operation after loading the parsed file into some temporary tables.

In order to create the acknowledgement file, I need the original file name. In the OnProcessInput of the service, it receives a stream of file data, and I can't find a way to get hold of the file name.

Any advice will be appreciated, thank you.

Dear All,

I am currently working on a project to record ORU^R01 into a global for a particular set of tests.

I have multiple OBX repeats that need to go into a specific fields withing one row/ record on the global.

I am having trouble finding a way to either count or loop though the OBX's correctly in ObjectScript often with the counter being undefined.

I have done this this way, as I am building upon an existing class to populate this global.

The latest iteration of my obx looping code is below:
