This week I am going to look at CPU, one of the primary hardware food groups :) A customer asked me to advise on the following scenario; Their production servers are approaching end of life and its time for a hardware refresh. They are also thinking of consolidating servers by virtualising and want to right-size capacity either bare-metal or virtualized. Today we will look at CPU, in later posts I will explain the approach for right-sizing other key food groups - memory and IO.

Session : Working with the FHIR Resource Repository

Hi Developers!

When you prepare your modules for ZPM (InterSystems Package Manager) it expects the certain directory structure for ObjectScript source files.

ObjectScript in your source folder need to be stored by types in the following subfolders. E.g. if you have the source folder named as /src the structure should be as follows:

/src

        /cls - for classes

         /inc - for include files

         /mac - for mac files

         /int - for interpretable files

         /gbl - for globals

And the ObjectScript should be in CLS (a.k.a UDL) and not in XML.

Example.

Ok!

Hi ,

I am new to cache and I want to check with the experts to see if using the ctrl-c option while checking the list of databases is valid one or will it cause any issues.

When i use  ##class(%SQL.Statement).%New() -> .%Execute() and then  .%Next() to go through the result set, i could only go through part of the result. And then, i have to call  .%NextResult() to go through the next part of the result. BUT, the  .%Display() could show all of the result.

How can i go through the full result once,like .%Display()? Or how should i do to go through the full result? Is there anyone can help me? Waitting!!!

I learned about the Open Exchange tab here at Intersystems. I wanted to look at one of them, but when I clicked it, it tried to go to the site, then brought me back to openexchange.intersystems.com.  I then saw a "not secure" icon in the browser bar. I tried this on IE, Chrome, and Firefox, and could never seem to get into the site to look at the site https://openexchange.intersystems.com/package/Cach%25C3%25A9Quality.

NOTE: seems to affect only the link above.

Am I missing something? Is there a special setting I need to set to see these ideas?

Thanks,

This service is only for IRIS and IRIS for Health and it is very easy to use.

Greetings,

I am trying to test an hl7 message inside studio and when I click on the test button I get this error:

"<FUNCTION>GetProp+2^%CDCalBk"  at  9:51 am.   $I=/dev/null:50333010   ($X=0  $Y=54) $J=50333010  $ZA=0   $ZB=""   $ZS=65536 ($S=66023400)

I have never seen this before! Any suggestions?

Here a simple test message:

Good afternoon,

I'm trying to convert to JSON, but the error <STRINGSTACK> is displayed when I run the command below:

Do ObjJson.Write(ObjSource.%ToJSON())

Does anyone know how I can solve?

Thanks,

Hi

Sometimes I have Atelier gettinng stuck on background task "Updating server container".

This maxes out one of the cpu cores and I end up having to kill the process. This is on version 1.3.139.

Hi,

I am wondering if there is a version of Studio which connects to Cache 2018.1 or do I have to use Ateleir?

Thanks, Kevin

I had my journal files all on one disk which died :( 

The database files are all fine, but I having issues.  Can I bypass the need for the journal files?

Environment: cache version : Cache for Windows (*86-64) 2015.1 (Build 429).

Platform: Windows Server 2008 R2 Standard.

database: oracle in OraClient12Home1 (64-bit).

We Configured cache and odbc in above environment. And we checked ODBC connection, it also working fine. And then we tried to connect the ODBC through the background but it's ending with gateway failed error. And again we tried the same process in foreground, it's working fine and also we got the data from the database. we checked the license key and cache privileges,all are good.

Hi all,

is it possible to omit the typical XML header line

when writing an the contents of a EnsLib.EDI.XML.Document  using the above mentioned operation. I´ve already digged into the config value Format. It only states that:

C(e) : output an XML header line declaring character encoding e. If e is empty use the encoding defined by the Adapter. If e begins with ! force the output stream's encoding.

I am trying to return a stream soap response using web services I can call my web service supply it with a xml string which works fine . I then work on that XML and try to return  a Stream but all works in the production when my service receives the stream after I get the error  as if its trying to copy stream to a variable and I am confused as to where that operation happens.

The errors I am getting 
ERROR <Ens>ErrException: <METHOD DOES NOT EXIST>zCopyFrom+28^%Stream.TmpCharacter.1 *Rewind

and here is the stack trace in case I am missing something

• $$^zGetErrorTrace+3^Ens.Util.Trace.

Hi All,

I have a class method, this can be any cache expression to execute (usually a class / method and args) and and args stored in a variable, for example;

set aa = "##Class(Utils.Test).Run(1,2,3)"

do aa

I tried using $classmethod(class,method,args..), by extracting the values but sometimes there can be no arguments, or arguments such as ;

("2019-01-01","1,2,3,4")

which causes issues while running the $classmethod, (i am using $P to extract the Class, Method and args).

Is there any simpler way of doing this?

Hi Everyone!

Hi folks,

I started to play with docker and InterSystems products, it's amazing, but I got the error when try to load the IAM-0.34-1-1.tar.gz image to docker:

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker load -i IAM-0.34-1-1.tar.gz
open /var/lib/docker/tmp/docker-import-547148651/IAM/json: no such file or directory

Bellow docker and docker-compose version:

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker --version
Docker version 19.03.2, build 6a30dfc

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker-compose --version
docker-compose version 1.18.

In .NET Core you have an option to extend a session using a "sliding expiration". This means that if over half the time has passed and the user actively uses their session then the expiry timer gets reset and the user remains logged in. This can lead to the curious situation where you have an active authenticated user with an expired access token being used in data-access requests.

Hi Community:

Could Global Summit be only a few days away? We've hit a record for attendance this year, and, if you aren't based in Boston, we're expecting summer-like weather.

I just wanted to let those of you who can't attend (maybe next year) know that you will be able to livestream the morning keynote presentations for all three days of the Global Summit. Listen in as featured speakers from InterSystems and from business, academic, and healthcare organizations share their visions of future technology.

Follow the livestream link and click the Launch button for the appropriate day.  Here's the program:

We have a case where we have 1 message coming in, but then sending two messages out to the same location. Even with FIFO sometimes the messages get out of sequence depending on what is need to be done to the message in the DTL before send. Is it possible to call sleep or Halt or write some kind of a function to put a pause in a routing rule between two sends?

I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.

When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:

#5002: Cache error: <PROTECT>%LoadData+7^EnsLib.HL7.Message.1

Tracing that back to the source, I find:

Lock +(^EnsLib.H.
