Hello...

I need to convert a array (JSON) in a List Of String. I think, there is some method that does it directly.

Something like that:

SAMPLES>set list = ##class(%ListOfDataTypes).$fromJSON("[""a"",""b"",""c""]")

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map frm %Library.Array instance to %Library.ListOfDataTypes

I have reading about this but I don't found some trick to help me.

Hi Community...I am trying figure this out any help appreciated. Thanks in advance

The service is a file passthrough that picks up a PDF and then uses the BPL code below to create the rest wrapper and sends the stream data. I am not grabbing the stream from the inbound correctly, "request.Stream" or "request.StreamFC" always produces the following error.

Here is what is sent and returned in the message..

request:

<Stream>

15@%Library.FileCharacterStream

</Stream>

%New error handling

Hi,

On a persistent class, I have defined an %OnNew method that validate some properties with appropriate status code for each kind of error.
Question is: how do you catch the specific error when %New is called on this class?

Surrounding %New method with a try-catch not seems to work.

Thanks

One aspect of source code management is how to deal with the almost inevitable need to upgrade your Caché or Ensemble platform to a newer InterSystems release.

It's long been my experience that InterSystems does a very good job of maintaining backward compatibility. Code that works correctly on, say, 2012.1 is very likely to work correctly on, say, 2015.2 without any modification.

I'm trying to read PID-3 and route the message based on if a certain prefix existed, but I keep getting Property Does Not Exist.

I've tried

HL7.(PID:PatientIDInternalID()) Contains "COS"

HL7.(PID:PatientIDInternalID(1)) Contains "COS"

HL7.{PID:PatientIDInternalID()} Contains "COS"

HL7.{PID:PatientIDInternalID(1)} Contains "COS"

This is a 2.3 MDM message. Thanks!

Credentials for a Productions are stored as plain text in ^Ens.SecondaryData.Password and exposed as plain text via SQL table Ens_Config.Credentials which is not ideal as only admins should know the credentials.

I can create my own adapter etc... to store and use encrypted passwords but does anyone know if there is a standard way to do this in a Production?

Alternatively, am I missing how to secure this so the production can run and someone can monitor and operate a production without access to the SQL table or global?

Speeding up $listget

Hi,

I'm trying to find the faster way to get the data from a class, and I find it very slow compared to traditional globals. So, I hope some of you can bring some light to me :-)

I have thousands of registers in a class, and to access it quickly I'm going with $o at the index. From there, I get the values using $listget(). Something like that:

I have installed Iris in Docker container with the above version. I need to create an additional user to log in via ssh. I have created a user and put in both the irisuser and irisowner groups, and created a user in iris with permissions. But, when I run "iris session iris" I originally got an error about permissions: /usr/irissys/bin/irisdb: Permission denied.

I looked @ the /usr/irisys directory and the permissions was only (r-x------). I changed to (dr-xr-xr-x.)and now I get a different error:

Invalid ownership for ./irisdb

Any suggestions?

Do you have any experience / recommendations / best practice on how to update server-side data residing in a Cache database via a REST service?

A naïve approach would be to send a full JSON representation of the data object via an http POST to a method on a REST handler class:

<Route Url="/mydata/:id" Method="POST" Call="Update"/>

The problem I see here is, if only one of the data object's properties has changed, how do we know which? Or do we simply overwrite all properties?

I think I already know the answer to this but I thought I'd ask anyway. So the Node.js adapter allows you to perform operations directly on Globals. Does the InterSystems.Data.CacheClient.dll or InterSystems.CacheExtreme.dll provide a mechanism to access Gobals directly or are you accessing globals via Caché ObjectScript classes?

Ensemble Queue Counts Incorrect

A couple of our queues in Ensemble are reporting a queue count of one however there are no messages in the queue. Does anyone know what the best method is to reset to the queue count back to zero or remove one from the queue count?

Hi All,

We are accessing the InterSystems`s cache database via UNIX ODBC and displaying the data in PHP website . Recently we have upgraded the PHP version to 5.6. We are getting the nondisplayable characters (�) for only strings. But the numbers and date fields are displaying correctly.

While querying the database via ISQL everything working fine (No Special characters).

I have looked around the internet and found the PHP 5.6 changed the default character to UTF-8.

For this issue anything, we can do from cache side.

Thanks in advance.

For a HL7 production, How will I be able to use two different segment level transformation (sub transform) in the main transform.

For Ex:
Few mappings from source PID --> target ZAX segment (subtransform 1)
Few mappings from source PV1 --> target ZAX segment (subtransfrom 2),

In the main mappings, I have used subtransform 1 followed by subtransform 2. It doesn't seem working fine.

Any suggestions please. Thanks:)

Insert SQL

I am inserting rows in a table. This table is appearing in all namespace as I did global mapping.

So once I run insert command from a method, it insert the rows. When I run the same insert command from other namespace, it replace the existing data in table.

Insert command is same in all namespace but the data I m inserting is different.

I must be missing something. We have done encoded PDF's in the past with the Encoded PDF in OBX.5.5. When I have used this code in the past I was only working with 1 OBX, but I have a case where I am having multiple OBX's and having to loop through them and I am renumbering the outbound OBX.
