Hi,

Please, advise how to programmatically set "System Mode" value.

Manually this value can be set via Management Portal > System > Configuration > Memory and Startup > System Mode dropdown.

Value can be programmatically obtained via $SYSTEM.Version.SystemMode() , but I couldn't find a programmatical way to set it.

Thank you.

Zen Report page number variable

I have a report that requires a different header block for the first page and another for subsequent pages.

Is there a way to direct a header page to another header page based on what the current page number is?

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. 🔄

1º We have our hexadecimal as follows:

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method"). // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Hi,

I am using embeded python to utilize some pythonic library but i got a problem on my hand.

One of the python function i am using return multiple values

in python you would do something like that :

val1, val2, val3, = function(params)

In COS I got something like that :

lib = ##class(%SYS.Python).Import("lib")
val1 = lib.function(params)

And I don't know how to get the second and third values.
Is there a way to get them?

Hello friends,
I am having the following problem when passing a parameter in the execution of a zen query?
If the parameter has more than 50 characters of the error.

Is there a configuration or solution to this problem?

I have a <tablePane> element with OnCreateResultSet and OnExecuteResultSet methods; autoExecute is "false" but the OnCreateResultSet and OnExecuteResultSet methods are nevertheless called on page load.

I want the user to be able to press a button to submit the parameters, then have this button call tablePane.executeQuery() to execute the query.

autoExecute is simply igonored. We're on 2014.1.3 with plans to upgrade to 2016 soon.

Are there more settings I need to set? Or is this attribute simply ignored?

We often have troubles with performance when joining tables with about 10 million rows together.

Sometimes we can't say what the cache engine is doing, it's just sucks and never finishes.

Then we have to rebuild the query and loop first on Orders and then on OrderPositions.

this is what we want:

EDITED: the join was only forgotten

Hello,

We would like to learn how would you approach this task.

We would need to check every day a set of folders which are outside our server (in fact we could see them as if they were "inside" the server), then we need to check for modified or created files in the last day, and move all the ones which match the criteria to just one folder in our server.

We have thought about doing the following:

1) Create a task to run it each day:

Hi,

We are using CACHE 2017.2.1, I would like to retrieve data from Journal for killed global. Let say we have global name ^ EMP(123) with data and also have some child nodes and it has been killed by using cache kill command for some reason and we don't know who has executed this and when. My questions are below.

1) Can we get back the data of killed global from journal files,Is it possible or not ?

Hello Community,

we read data from an Oracle database. The desired order is created by an 'order by' in the sql statement. The individual elements of the result set are converted into objects and inserted into a parent object using 'insert' on a property, which implements a one-to-many relationship with the result objects. Later, we iterate over the objects in a for loop and process the contents. At this point the order is apparently no longer identical to the order in which the elements were inserted.
