Parsing null values in JSON

Hello everyone,

 

I'm creating a REST API with InterSystems Ensemble.

I already have a POST route that parses JSON content into an object defined in a class.

To parse the JSON content, I'm using the JSONStreamToObject method in the Ens.Util.JSON class

Here is how I use it:

Hi everyone

I see that a new Apache bug has been discovered, and since various InterSystems products use an Apache webserver, have Intersystems released any news or updates on this? I'm not seeing any updates, press releases from them. Anyone know anything?

Andy

Convert hexadecimal to base64

Hello, first of all thanks for your time reading our question 💭

 

We would need to be able to transform a hexadecimal string to a base64 coded one. 🔄

To be specific, our use case is this:

1º We have our hexadecimal as follows:

4C5803040101020179C3913EC3BA7C4C580708010101021824584D4C

2º We convert it to ASCII:

LXyÑ>ú|LX$XML

Does anyone know of a relatively quick and straightforward way of converting code written in the old dot scoping syntax with argumentless do (see here for reference: https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_cdo_legacy) to the modern parentheses scoping syntax? It's not too bad to do it by hand, but it's also easy to make a mistake and leave a "quit" in an if statement by accident for example.

in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?

Locking / unlocking

Hi.

What is the best/right way to unlock the object in ObjectScript after the lock was acquired by %OpenId class method? Setting the opened object to null (Set object="") doesn't release the lock.

Regards,

Matjaž

Hello, 
I'm currently working on a custom version control implementation. 
I'd like to show differences between a copy of a previously saved routine as a merge of the ^ROUTINE Global and the current version of that same routine. 

I've found legacy Documentation for %RCMP which does the trick in the terminal but I'd like a similar result stored inside a variable. 
I also want to show differences, not only see if they are the same or not. 

The management portal has that exact feature, so maybe someone can direct me to the function that is being used there.

When i use &sql(SELECT ......)  in Cache I can watch the generated code
In the generated .int code and see what is happening.
Just with my normal rights

Now in IRIS I have just 4 line calling some class %sqlcq.***
With enough rights i find there is no such class but the generated .int routine
%sqlcq.IRISAPP.xEZgUjdXCCgQdZQPpRdOye1Ci2ue.1
That holds the code that i had in my .int on Cache

Can i switch this back somehow ?

Driver odbc performance

Hello,

I'm using the InterSystems Iris odbc driver (DriverODBCVer=02.10) to get data from Iris table but it is slow.

Is there any options to improve performance ? Increase the packet size ?

Change to do in odbcinst.ini / odbc.ini to make it quicker ?

 

Thanks

Hi,

I have a DR member and in this cache server the database "cachetemp" start to getting bigger without any reason (50GB that was all the free disk space we have)

In the members of the mirrors the cachetemp its ok and the size is 31MB.

I restarted the server because I read that the cachetemp database purge when restarting, but didnt happend.

Any recommendation to clean this database? can I just deleate the CACHE.DAT from this database?

Thanks!!!
