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?

Cache: Binary export output

I have an odd binary result exporting a specific routine via Studio, Export. Below is the beginning. The seemingly same routine in a different directory is exported fine, regular human readable code. Inspecting ^ROUTINE and ^rIndex did not give me any clues. Any insights?

Hi,

I am using embeded python to utilize some pythonic library but i got a problem on my hand.

One of the python function i am using return multiple values

in python you would do something like that :

val1, val2, val3, = function(params)

In COS I got something like that :

lib = ##class(%SYS.Python).Import("lib")
val1 = lib.function(params)

And I don't know how to get the second and third values.
Is there a way to get them?

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

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 all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.

Hi,

I am trying to connect to another server using %Net.HttpRequest.

I keep getting this error : SSL23_GET_SERVER_HELLO:unsupported protocol.

My guess is that the site I am reaching for uses TLS1.3 which is not supported in 2016, But I cant right now ask my client to upgrade.

Is it possible to override this ? install some kind of a patch or a more recent version of openssl on the server ?

Thanks

Amiram

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

Hi Allen,

A partner have decided to change the algorithms that were used to connect on it's SFTP, but our version of libssh2 don't match with the list of it's HOSTKEYS algorithms.

If i update the library with the last version without to be sure that it includes the old algorithms, i risk to break the connection for other cases.

all suggestions are welcome. Thx

KR,

Amine

The task for a file on disk is to open it, find a keyword (unique) and then read the file line by line, starting with the line with this keyword, then find the next keyword (also unique) and read from that location etc. I would think ObjectScript classes should be able to do that, but the solution eludes me. I probably need to use FindAt to get a position, but ReadLine does not seem to have a position argument. Any advice?

The goal is to identify programmatically all SOURCE namespaces on a server to which the routines are mapped. In the example below from the Namespaces page in Management Portal the answer would be USER. But some other namespaces on the same server could be mapped to a different namespace or even mapped to itself.

I am sending an httpRequest from ObjectScript to a python server. I am not receiving a response in OS

OS config On the client side

// Create an HTTP request object
Set httpRequest = ##class(%Net.HttpRequest).%New()

// Set the server URL
Set httpRequest.Server = "http://127.0.0.1:8080"

// Set content type to JSON
Set httpRequest.ContentType = "application/json"

How to remove accentuation?

How to remove accentuation of a word?

Ex:

Árvore = Arvore

você = voce

Então = entao

The words above are in brazilian portuguese, I need to get rid with the accentuation such that I can compare two sentences.

Thanks in advance.

Our 3M Computer Assisted Coding system goes down on a regular basis for updates, the Applications folks like us to Disable the Business Operations when this happens and start them back up when they page the on-call person. The Business Operations have to be started in a sequence to guarantee that all the ADT being sent it processed before we start sending everything else.
