Globals are multidimensional sparse arrays which are stored in InterSystems Data Platform. Everything in InterSystems Products is stored in Globals: Classes, Tables, Documents, Code.
Currently I have a program that is going to be used to compare global nodes between namespaces. Using nested FOR statements I am stepping through global nodes and comparing between the namespaces, if the global values are different I then parse the node comparing each delimited segment.
This is working.
I want to now be able to set what global I am in as a variable to expand on this concept.
I have a global whose structure is multi-level and I am trying through a class and a SQL query to display a table which includes all the values and levels.
Customizing Stored Procedures with ObjectScript directly has been useful to access NoSQL storage and external messaging via integration, to present output in tabular format.
We are trying to create a simple class extending %RegisteredObject that could be used as a singleton. However we are not able to store it in a global to later be retrieved (by the same process but elsewhere in the code).
I found the thread that discusses object mapping, in particular mapping a common global among more than one namespace. The example that is given is a simple one when it's ^global(sub1, ^global(sub2, etc. However I'm having trouble getting this to compile/work when the global has a fixed subscript amongst variable ones.
I have this global in namespaces LAB and ARK in the following format:
^CB(1,sub1)=....
^CB(1,sub2)=...
^CB(1,sub3)=...
Here is what I have for this. In it's current state it throws tons of errors:
As noted in the previous article Native API has some limits. So I did some research on a more Terminal-like interface that provides me with access like a console or the IRIS terminal to allow my $QUERY over a global and other nice commands that are not supported/mapped in NativeAPI for ObjectScript.
We have a global with 65 million entries. All we are doing is just iterating through each entry to find out the total no of entries. It is currently taking 110 minutes. Is this something normal? What can we do to speed up this process? Below is the program for just iterating each entry in the global.
s sub=" ,count=0 f{ s sub=$o(^YYY(sub)) q:sub="" s count= count +1 } w!, "Total Count:"_ count
InterSystems IRIS currently limits classes to 999 properties.
But what to do if you need to store more data per object?
This article would answer this question (with the additional cameo of Community Python Gateway and how you can transfer wide datasets into Python).
The answer is very simple actually - InterSystems IRIS currently limits classes to 999 properties, but not to 999 primitives. The property in InterSystems IRIS can be an object with 999 properties and so on - the limit can be easily disregarded.
How do I retrieve the name of the first GLOBAL from within the GLOBAL directory? Should I use some syntax with $Order or $Query or is there another way?
I have created a global say ^myglobal and entered some data. I am storing the name of global in databases and fetching the name based on some criteria. I am getting "^myglobal" in return from databases but i am not able to fetch the data I stored in the global.
I tried set var = result.global which gives me "^myglobal" in var. Doing WRITE var will return "^myglobal" and not the data i stored in this global.
I want to fetch value from a global without being limited by the namespace. Is there any way of referencing the values from a global to a different namespace?
We are trying to come up with huge DataStore which needs to store HIPAA transactions and Data getting partitioned with idkey - YYYYMM. Current Live data get inserted into current Month DB - HIPAA_202306. 10 years (Hipaa retention policy) old data is going to be sitting in to 120 DBs ( 201606_HIPAA, 201607... 202305) for historical audit legal compliance purposes.
Currently if we create Namespace we get 2 databases - CODEDB for routes/classes & DATADB for journals data.
I would like to get a list of all globals that have been read or written during a given context. In Portal, there are counters in dashboard that give the number of read/write to globals in general.
What I am looking for :
- some handler (eg: like $ZTRAP) that will be called everytime something is read/written to a global.
- to activate a "global log mode" in Portal that will dump some information to a file (like ^ISCSOAP for SOAP requests).
ACB> K ^GlobalManualSend ACB> D $System.OBJ.Load("C:\Users\BNAPC\GlobalManualSend.xml") ACB> Set sc = ##class(%Studio.Project).InstallFromGbl("^GlobalManualSend","fv")
I have a %GlobalBinaryStream object that I'm trying to save as a local file after being received through a SOAP Web Service.
To do this, I created a %Stream.FileBinary object and wanted to set where the stream copied to this object would be saved by using either the DefaultStreamDir() ClassMethod or the NewFileName() ClassMethod. However, the documentation isn't very helpful on how to use these ClassMethods.
During a migration from a rather old Caché Version (2016.1) to IRIS I met the problem to migrate Streams. The difference in the storage Global is minimal It's not a big effort to do it manually for a few streams. But for some thousand streams I hope there is a tool already available. But where?
We are migrating to new servers, and I need to copy the information from Business Partner's over to the new server. Is this information in a Global or SQL table somewhere that I can export and import into the new IRIS environment?
Though the access is quite comfortable (in traditional COS sense) there are 2 main restrictions that hurt:
#1) It is not saved to disk unless your application includes code to save it specifically. #2) It cannot be stored in or exposed through SQL tables there are some more I'll show how to overcome these limits
Those of you that worked already with ECP might know that it operates not only across operating systems, processor technologies (big-little-endian), but also -with limits- across versions in C/E. This cross-version feature also includes IRIS (verified for 2020.1) and C/E (2018.3)
