I am familiar with $TEXT which can get you any line in the current routine provided you know the offset. For example, $T(+1) will get you the first line of the current routine at the run time. In the same vein, how do I reference the current line number/offset at the run time? Something like $T(+$CURRENTLINENUMBER) where $CURRENTLINENUMBER is not yet known to me function. The sample below would write 3 as the line number.

RTNNAME
S A=1
W $CURRENTLINENUMBER

AWS API calls

This question is about calling AWS REST APIs. Based on:

http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

AWS requires REST clients to call their APIs using Signature Version 4 which in case you don't know what I am talking about is a pain in the neck. Here comes the question:

Has anybody, by any chance implemented the v4 signing alg. in COS? If yes, would she or he have the kind heart to share?

Thanks,

Chris

creating a test server

hi, new here, and new to cache and deepsee.

i've been trying to setup a copy of our production server so we can use it for testing/development.

i did a full backup. moved it to the new server. ran the DBREST command. got it to restore but seems like permissions get all messed up. and it just generates a bunch of errors.

is there an easier/better way of doing this?

Replace elements in $lb

Let's say I have a list structure:

set list = $lb("stri,ng", $c(0), 2)

I want to replace all $c(0) elements with empty elements, so my list would look like:

set list = $lb("stri,ng", , 2)

What's the fastest way to do that?

Decoding Base64 PDF File

Hello, I am writing some cache code that will pick up a PDF file, Base64 encode the contents and then send on to a third party system within a Long String (via their API). I have been testing this and discovered that the PDFs do not open within the supplier system (I get an error saying that it hasn't been decoded correctly). I wanted to prove that the issue does not lie with the way that I have Base64 encoded it within Ensemble, and therefore as a test wanted to Encode the PDF stream, then decode the stream and write out to a new file.

We have multiple databases running on a single server. I have duplicate interfaces on each database.

If we're doing testing in copy #1, the interfaces should be running in that copy. I want to block analysts who try to start the interfaces in copy #2.

So, I'm looking for something that would check the port and tell me the status: already in use or free.

My challenge is that this system needs to stay ISO/ANSI compliant.... so I can't use any of the newer tricks.
Is there any plain-old Cache' I could use for this task?

This tells me that there is no timezone offset on this table/field:

Select TOP 1 GETDATE() as Now, TimeCreated FROM ens.messageheader ORDER BY TimeCreated DESC;
Now TimeCreated

Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.

The routines have while loops and perform while loops so long as the time parameters are being met.

What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:

Working on implementation FHIR to my project, I found interesting project HAPI-FHIR, which could help me to quickly launch my FHIR api server with InterSystems Caché as a storage, because this projects uses Hibernate to connect to database, as an example they use DerbyDB. I tried to change settings to use InterSystems Caché, but unfortunately it does not work and throw some errors inside HIbernate. As I found in Caché documentation, I have not some many options, I just have to set Cache dialect, and set database url.

most of my jSON data is single words, but when it comes to sending chunks of a memo/email via JSON, that totally different

which is the correct conversion process to prepare data ready to insert into the data part of a JSON string so that all problem characters are converted

JSON of course crashes if you use the wrong format of quotes (single or double) and you ned up having to use &QUOT and \' to get around that but is there a simple call to something that will just take care of preparing the data from the JSON string both on the inward and outward part of JSON

$CASE For Long Stories

Hi, Community!

$CASE is a fine syntax sugar for "Ifs" with one-line/one-word expressions, like in docs:

SET daynum=$ZDATE($HOROLOG,10)
  WRITE $CASE(daynum,
              1:"Monday",2:"Tuesday",3:"Wednesday",
              4:"Thursday",5:"Friday",
              6:"Saturday",0:"Sunday",:"entry error")

But if my expression for a current case is a multi-line business logic? Can I use "{}" somehow or better go with "IF" instead?

I was running the %File:FileSet class query, with my development user, but I am unable to run this query for an application user. Does anyone know what resource or service is needed to run this query? Assume the user has access to a certain directory on the file system needed for the query.

On second though, having tried almost all the available resources and services, perhaps the user doesn't have access to the directory. How to tell when the error is this:

Hi,

An exception occurs randomly.
I expect the value of ^TEST to be 20, but it's not.
Did i miss something like closing, flush the stream or locking the global?

I want to override the Get and Set methods of a class property. The class maps to a pre-existing global. The property is defined like so:

Property Invalid As %Library.Boolean;

with the property mapping to a node like ^GLOBAL(Code,"INVALID")=1
Code is a property in the same class.

The value can be 0 or 1 or the node might not exist. When it doesn't exist I want the value of the SQL field to come out as 0 (false).
