#InterSystems IRIS

I have an existing Python script that opens a child session using the pexpect library. But currently all it does is send hard-coded commands to the Cache process and expect a hard-coded response back in order to continue in the script.

I would like to run a Cache routine from the script, pass in a parameter, and wait for a response that will be different every time (a date, in this case). So the call would be something like D $$Tag^Routine(parameter) and wait for the routine to complete and return the response.

Hi,

I like to validate some use cases and have the following question. I am relatively new to IRIS. Perhaps someone can help:

1. I have a global m[x,y,z,f] distributed across multiple sharded instances
2. I know that i can set assign computed SQL expressions to class variables using Objectscript
3. Is there a possibility in Globals API to do the same ? Set f = x + y as a computed expression in the global m[x,y,z,f] ?

a. We would want to use the global API to change f programmatically using code

It sounds strange though it's embarrassing.

I have a class with ClassMethods written in ISOS and Embedded Python.

The ClassMethods written in ISOS start in the Background as usual. No problems

Hi

I'm using an embedded SQL statement with a a cursor-based Embedded SQL query that uses host variables in the where clause, however, what I'm doing doesn't seem to work. Can anyone help?

I want to write some code differently to run on Primary, Backup and DR depending upon their status.

If its Primary then do something, if Backup then something else and if DR then do something different from both Primary and Backup.

Hi all

I'm testing migrating our existing installers (without ZPM) using the docker dev template as a basis with a commercial image and licence key.

So far everything builds as I expect, but the one issue I have is the production doesn't apply itself automatically.

In my iris.script I have custom installer that uses this manifest below but it does not observe the last three steps

Hi,

I'm trying to get the ECP status of 2 servers using $system.ECP.GetProperty("ServerStats") and $system.ECP.GetProperty("ClientStats"), but I'm not able to find the documentation of the values returned:

For example, on the server side I execute this:

I use Microsoft Query via Excel to query an Intersystems database.

Since upgrading from CACHE to Intersystems, lots of reports fail to refresh twice - by which I mean I can open the report (which may have several separate queries) and query the database once, and then it will refuse to reconnect.

I get:
[IRIS ODBC][State : S1000][Native Code 417] .... Access denied

If I then close and reopen excel, I can run the query again.

While creating my latest examples for the JavaContest I faced the need
to communicate with my code from a program in IRIS to my Java code.

Communication with |CPIPE| worked as READ or WRITE but not both?
In the Documentation Named PIPEs are explained rather shortly.
"Once open, a pipe acts like an ordinary device." Not so precise.
I failed to achieve my expected READ/WRITE as TCP would offer.
