Validate signature from string

Hello,

We would need to handle the following use case:

A system replies to our GET with a list of codes and a signature.

Each code has been signed with the SHA512withECDSA algorithm

We would need to:

1 Concatenate all codes in a string

2 Decode the string which is in Base 64

3 Validate the string using the signature which we get in the reply

We have read for step 2:

Base64Decode

SIMPLE FTP PRODUCTION

Hello developer community, I'm looking for Ensemble production sftp examples. I need to copy hl7 files hourly from several servers to a central server. The local documentation is no longer as good as it used to be. I remember several years ago, the documentation would take you step by step doing this. Any information would be appreciated.

thanks,

Rob S

Hello ALL!

I am having trouble fining a way to derive (a list, an array, a file doesnt matter yet how it returns) ALL of the targets of a routing rule.

For example lets say I have:

  • a router of class: EnsLib.MsgRouter.RoutingEngine
  • Business Rule: HappyRRN
  • 1 rule set having 5 rules that each send to 1 DTL and 1 Operation (5 targets total)

My intent is to use some utlities we have created to disable all of the target operations of this router if the router errors out.

To do that I need the list of target operations.

Hi all.

A long time ago I enabled Activity Monitoring to be able to save myself headaches in the future when looking at the performance of various message routes through our productions. It's served it's purpose of answering questions on how many messages we process a week etc but I had not had the chance to really dig down into the stats for specific message types or destinations to pin point issues.

Cache SQL question

I have a table with 4 column: MRN (primary key), Name, DOB, and Gender. I want to bring in the values on all of the columns into a DTL. Currently, I declare variables for each of the columns and using 3 select statements.

Hi,

The company I work for has one software application that uses an IRIS database, with almost all the others using SQL databases.

On a SQL database, we can create local tables and create views. These are invaluable when it comes to reporting, and everyone here is quite up to speed with using SSMS to create functions, stored procedures, etc.

%iFind.Highlight

Hi

I've been working with SQL using an iFind index to search text. Using the %iFind.Highlight function in my SELECT statement I can get text back that highlights the found words using <b> and </b>

I am aware that using ##class(%iFind.Utils).Highlight, I can pass a parameter to override the <b> tag and use instead a <span> tag with style to change the background color of the found words.

Is there a way to override the <b> tag from a SQL statement?

Thanks

We've traditionally run a selection of development environments from a single cache instance using different namespaces for DEV TEST PREP etc. This has come with a few drawbacks, mainly that you then cant break down into namespaces per environment and everything is sharing various options.

Is there a massive overhead to running multiple cache instances from the same 'box' instead?

How best to share the memory setup in that situation, we usually pre-define around 80% for the instance, do we just share that evenly between the multi instance scenario?

Running Cache 2017.2.2.

I'm trying to make a REST API call in JSON format. When using the example in the class reference documentation the getJSON method in the %Net.Http class throws the error <METHOD DOES NOT EXIST> on a %Clone() method in the %LIbrary.DynamicObject class. I even changed the parameter to a JSON string to no avail. The code will then fail on the %Compose method (examples below). My workaround is to use the %Net.HttpRequest functionality. Is there another workaround to this?

Multiple servers or CSPGateways

Hello to you all,

Strange titel, so I'll explain better:

I now have IIS-server with a CSPGateway installed. This works fine. But I want to use a rest-service (or another zen-page, whatever.) on another cache-server

So on IIS i have an application called CSP. (/csp) This contains the handler to map it to the CSPGateway.
It has been configured to acces a cache-server (X) which will handle the request. But now I want, in this case, the request to be executed on another cache-server(Y).

When I start a fresh installed IRIS or a Container I always find Interoperabiliy (aka. Ensemble) mapped to namespace USER.

Is there any utility to remove this mapping by a click ?
unmapping it global by global, routine by routine, Package by Package is just a boring exercise.

To be clear: I look for a utility inside IRIS.

The external utility is obvious: Notepad (or any other text editor)
- clean iris,cpf,
- restart IRIS
It's fast, it's efficient, but it's really hardcore.

Until this week, my customer had Ensemble writing HL7 messages to my TCP listener, working fine on ageing physical servers (Windows Server 2003, Caché 2009). They had four app servers (app1, app2, app3 and app4) with an overarching DNS simply called "app". Ensemble was connecting to "app:port", and it somehow found whichever of the four app servers my background listener was running on, and the interface worked fine for 10+ years.

Hi,

When for any particular reason I need to update a record and don't want to pull the triggers, the keyword %NOTRIGGER can be used. But I've been trying to do the same when I change the row using the object approach, but I can't find it. Anyone knows if it's possible to avoid pulling triggers when working with objects?

Sadly, the utility "DISABLE^%NOTRIGGER" doesn't seem to exist ;-)

Thank you,
David

Hello community!

I'm creating a script to remove an item (component) from the Ensemble production, I know there is a manual way to do it but as there are several components the idea is to use a script to be faster.

I tried using %Delete() and doing a select on Ens.Config.Item, but this ends up generating several errors in production. Does anyone have any idea how I can do this simply?

We have a set of some fairly standard HL7 interfaces that usually end up doing about 90% of the same thing as every other interface. I'd really like to be able to write a script that I can modify some text, and have it create Services, Processes, Operations, DTL and Business Rules.

So, let me provide a more concrete example: I feel capable of a writing to and replacing variables within a text file, different process. This is obviously going to be pseudo-code, but my thinking is this

Create "Memorial Hospital Process"
