Hey everyone.

I'm currently looking at a process where we're utilising the Class Ens.StreamContainer, and was looking to do some deletions outside of any purge routines.

Having been burned before, I wanted to make sure that deleting the container also deletes the contents within.

From looking in the class, the %OnDelete ClassMethod appears to be removing an index from a search table and nothing more.

Hi everyone.

I have a function that may end up being called from a number of transformations at the same time, and within the function there's some Embedded SQL to first check if a local table has an entry, and then adds the entry if it doesn't exist.

To prevent a race condition where the function is called by two transformations and they both end up attempting to insert the same value, I'm looking to use the table hint "WITH TABLOCK" on the insert, but this seems to be failing the syntax checks within vscode.

Are table hints supported with embedded sql?

Hi everyone.

Is there a sensible approach to having a lookup table in Namespace A, and then accessing this from Namespaces B, C, D (etc)?

I'm trying to avoid creating a Global mapping of the lookup table global (^Ens.LookupTable) as I fear that it would then link all other lookups in that global and lead to some unexpected behaviour, but would be open to trying something in this realm if it's the best option.

Hi everyone.

I have a few processes where I rely on them being triggered by a schedule to run, and in the past I have relied on the following setup:

The Scheduled Task is a custom class that runs a minimal amount of code to simply create and send the specified service an Ens.Request, and equally the Service is also a custom class that simply passes the Ens.Request to the Process for it to kick the process off.

Hi everyone!

If you are working with IRIS 2021+ and you remove all of the built in entries for External Language Servers, there is an unexpected consequence that may prevent you from running an installer to upgrade your version of IRIS. This does appear to be a bug which has been raised with WRC, however there are some people that may have recently removed these settings and then will soon be upgrading their environment and could face this same issue.

Introduction

Say you have a receiving system that accepts HL7 and provides error messages in field ERR:3.9 in the ACK it returns. You require a different reply code action depending on the error message, however the Reply Code Actions settings for the operation do not provide this level of granularity. One option could be to create a process that takes the ACK and then completes the action you were expecting, however things can get a bit messy if the action is to retry the message, especially when trying to view a message trace.

Hi everyone.

I have a use case where I'm using embedded SQL within a Business Process to interact with a SQL table. However, when it comes to deployment into our production, the table wont form part of the deployment package created from the production.

Beyond manually creating the table on the production system, is there a standard way of ensuring that a table needed for a class is created during deployment?

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

Hi all.

I have setup a HL7 Operation using the HTTP adapter, and I'm getting what seems to me as an unusual response. When sending a sample message to the operation, I am getting a nested ACK. For example:

MSH|^~\&|||xxx|xxx|202209230806||ACK^HTTP^200|00|D|2.1|1
MSA|AA|RWSD7V5iuEC5F6zscDWz|HTTP ACK 'HTTP/1.1 200 OK' : MSH|^~\&|yyy|yyyy|xxx|xxx|20220923080633||ACK^A01|1663916793965||2.3||||||
MSA|CR|RWSD7V5iuEC5F6zscDWz|Error Message Goes Here.

Hi all.

I'm currently looking at a use case where I need to take a Stream, and then encode the contents as a Base64 Stream. This is currently achieved with a snippet of code that has previously been placed in multiple classes within this particular environment, and relied on the dotnet gateway (which suffers with a bug in 2022.1, corrected 2022.1.1).

Hey everyone.

I was wondering if anyone had come across a way of reformatting ObjectScript within VSCode.

I have the various Intersystems Extensions installed (InterSystems Language Pack, InterSystems ObjectScript, InterSystems ObjectScript Extension Pack, InterSystems Server Manager) but a formatter does not seem to be something included within this variety of extensions.

Hey everyone.

I was curious if anyone had any success/tips with regards to using a global or a system parameter/property to control the behavior of a transform or process/operation.

Is there a parameter I can currently reference from the system that can be used for an if/else, or am I best off creating a simple Global and setting it according to the environment I am in?

Hey everyone.

I have been revisiting our backup strategy, and spotted that IRIS supports VSS (Volume Shadow Copy Service) in Windows. This is quite attractive as an approach, as it automatically calls the external freeze and thaw commands.

However when calling these manually, there's quite a few parameters that can be set, and the documentation around VSS only states that the freeze/thaw commands are called.

Is there a way of controlling the parameters used, or at the very least know what the defaults are?
