I was interested in accessing IRIS (Healthshare) using Python. I found instructions how to this here: https://github.com/intersystems/quickstarts-python/tree/master/Solutions...

The installation went well using pip and when python executes "import irisnative" it works fine. It just fails with a connection timeout when I try "irisnative.createConnection(...)." Below is my code:

Is there a way to automatically transform Object Script arrays to Python lists? This code results in a list of arrays

Iter0 =  dbnative.iterator("HS.Data.OIDMapD")
for subscript, value in Iter0.items():
    print(f"subscript={subscript}, value={value}")

Here is the result:

subscript=1, value=2.16.840.1.113883.3.86ISCInterSystems Corporation

I suppose it would be too hard to parse this into a list, I was just wondering if there was a function provided to make it convenient and proper.

Thanks,

Marlin Mixon

I have the object query:

s Rset=##class(%ResultSet).%New("%SYSTEM.License.UserListAll")

I can loop through that query and it generates the report information that I need.

I have a Python process where I use the intersys import to connect to the Cache instance. But I have been unable to determine the correct syntax in Python for this query. Being that 'UserListAll' is a query I attempted to user:

res = <query>.prepare("select * from %SYSTEM.License_UserListAll")

I am writing a Python tools I want to access the %Monitor.System.License properties:

  1. AvailableDist
  2. AvailableLocal
  3. MaxUsedDist
  4. MaxUsedLocal
  5. CurrentUsedDist
  6. CurrentUsedLocal

Initially I want to develop Objectscript to verify access to the properties. But I can not figure the proper syntax.

I first attempted:

set ans = ##class(%Monitor.System.License).AvailableDist

which failed.

I tried another approach:

set ans = ##CLASS(%Monitor.System.License).%GetParameter("AvailableLocal")

Configure IRIS using Python

I am trying to configure IRIS using python. The first task I wanted to do it change the journal directory. I cannot figure out the right way to work with the Config.Journal class with python. I can get the text to query the current setting.

returnValue = dbnative.classMethodValue("Config.Journal","GetList")
print(returnValue )

But I don't see a straightforward way to parse the $List returned by GetList() I was hoping there was an easier way.

How do I

1. Query configuration parameters?

2. Set configuration parameters?

Using python?

When looking at the "Current License Usage Summary" web page, there is a line for both local and distributed "Maximum Connections". I have scrutinized every class that seems reasonable to contain this information but have found nothing that matches the values on the web page. I do not believe these are related to license specifically though I did review all of the potential attributes of the license related classes to no avail.

I'm after some more in-depth information about how the embedded python is implemented with regards to how it works when a python method is called from a CSP page. Will it run in the same Windows process? Will there be any issues with multitasking (considering python doesn't seem very good at this)?

Also, is there a performance penalty to pay for running embedded python vs "using IRIS APIs from Python".

Another question is what python interpreter the embedded python is using? Is it an Intersystems one or the regular c.python? Version?

Excited to go Python!

So, I know that I can return a SQL Error message from my SQL Procedure written in ObjectScript, with code like this

$ cat <<EOF | irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER
CREATE or REPLACE PROCEDURE test()
LANGUAGE OBJECTSCRIPT
{
 SET %sqlcontext.%SQLCODE = 400
 SET %sqlcontext.%ROWCOUNT = -1
 SET %sqlcontext.%Message = "test error message"
};

CALL test();

EOF
[SQLCODE: <-400>:<Fatal error occurred>]
[Location: <SPFunction>]
[%msg: <test error message>]

But I did not find how to do it with Python. I can't find %sqlcontext variable available there

I have a python script that is pulling the cache instance key expiration date ( KeyExpirationDate() ) which comes back as an integer. With the queryscript function - $ZDATE(73284) I can derive the actual expiration date. Is there a manner or method of creating an equivalent Python script that will convert the integer return by the KeyExpirationDate() method into a date string?

Build Python bind

I'm testing with an application I'm writing in python.
But I noticed that the pythonbind3 library will only work on the same machine where the cache is running. Is there really such a dependency?

I'm trying to run the examples that are in the / dev / python / samples3 folder, but they only work if I set "LD_LIBRARY_PATH" with the path to the cache installation folder.

But... I have this error when LD_LIBRARY_PATH is empty:

I have developed a process that pulls data elements from a cache instance using the tools provided with the "intersys.pythonbind3" import. This is a windows box. After validating the process, the next step is to install the process on a site (Windows) that does not have an installed version of cache and access the cache instance remotely. But, since intersys.pythonbind3 is part of the cache install, I am not sure what to do to allow this process to function because of the missing import.
