%Net.SSH.Session

We are getting CoClass not available [80040111] when using %Net.SSH.Session. Does anyone know if there is a security setting that would disable this object?

Any help would be greatly appreciated.

Dear All,

I'm looping through a list with characters (Parenthesis, square brackets etc) and I wish to remove these from the list.

The for loop and IF logic are effectively removing these items from a list.

However the variable I use for the maximum number of loops carries on beyond the number of items of the list after removal.

In the output value for these I get the integer of the for loop instead of a null for the empty list fields.

I can see in the documentation that the end variable is not editable once the loop is started.

I have just started to experiment with Using IRIS in Docker.

My first objective was to be able to enable global persistence within a Docker container. Using the following command I have managed to achieve this:

docker run --detach --publish 52773:52773 --volume /data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 store/intersystems/iris-community:2020.1.0.199.0

Within this container, I have created a simple global:

for i=1:1:10 set ^tmp(i)=""

Hello Community,

we need your help with Cache 2017.2 freezing on Linux machine.

Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.

Product is Caché
Version is 2018.1

Hi

I'm working in a security issue of the system that says that once you are logged into a session 
and you save this cookie. You can go to another navigator and use this cookie to be registered. 

I would like to chenge this cookie once user is logged into my system but I can't logout and 
login again because all my cookies are removed.

Is there a way to change to cookie or renew it?

Thanks a lot.

SQL Statement Highlighting

Hey Community,

my Caché Version: 2013.1 and can't update now.

is it possible to highlight SQL Statements like in embedded SQL with all the features from SQL Statements?

Actually I use SQL Statements with a simple string like:

set myquery = "SELECT TOP 5 Name,DOB AS bdate,FavoriteColors FROM Sample.Person"

But when the queries are more complex it will be very cluttered and unstructured.

Hey Community,

my Caché Version is 2013.1 and I can't update now.

I want to serialize a SQL Answer row into an Array filled with objects and then convert it to json.

Actually I use the following, which is very error prone when I have to do that often:

Hi!

I believe the simplest is (to work with csv delimited by ";"):


set file = ##class(%File).%New( "data.csv" )
    set sc = file.Open( "R" ) 
    if $$$ISERR(sc) quit    ; or do smth

    while 'file.AtEnd {
        set str=file.ReadLine() 
        for i=1:1:$length( str, ";" ) {
            set id=$piece( str, ";" ,i ) 
            write !, id  // or do smth
        }
    }
    do file.Close()

Possible options:

different variants of error handling with sc code.

Embrace while loop into try/catch block.

And what's yours?

I am experimenting with Relationships, both Parent to Child and One to Many.

I have done some SQL look-ups and have searched through the documentation, however not in a lot detail, but wonder if there are more and better ways to access both sides of Relationships through SQL?

Thank you in advance for any help provided.

Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!

hi all,

I am looking to make a JDBC connection to my Intersystems Cache using the JDBC driver 2.0.0.

how can I do that? what will be the format
