Hello all.

I think the forum experience is great as whole, but it could improve even more if we had somewhere to share our ideas. So that's why I'm creating a thread dedicated for that purpose. Maybe this way someone from InterSystems could catch something good?

I am using a method: %OverrideGuidAssignment("NEW GUID HERE") to override my GUID, and would like to know if there are any parameters, which allow this method to return a status & or error msg?
If you currently set it to a variable it returns the new GUID you originally passed in, regardless of if it failed to override or not.

Thank you in advance

Hi, community!

Consider you need to exclude substring(s) from a string.

I did it with the following snippet:

/// excludes all the substrings from the string
ClassMethod ExcludeSubstring(substr,str as %String) As %String

{

 while ($L(str,substr)>1) {

 set str=$Piece(str,substr)_$Piece(str,substr,2,*)

            }

 quit str

}

So, for example:

This method is provided as a convenience for developers for use on development or test systems. You should not use this method on production systems as it will have immediate effect on the performance of end user operations.

Record maps are used to efficiently map files containing delimited records or fixed-width records to message classes used by the interoperability function, and to map files from interoperability function message classes to text files.

Record map mapping definitions can be created using the Management Portal, and we also provide a CSV record wizard that allows you to define while reading a CSV file.

I have several 1GB journals from a LIVE server that I would like to inspect (eg: check which globals have been updated over the time).

Is there a simple way to view those journals using another IRIS instance ? (eg: local installation).

I have been tempted to put those files directly into the journal folder of my local installation and restart the system, however I am concerned that the transactions they contains will be restored and will corrupt the local database.

InterSystems has corrected an issue that can cause InterSystems IRIS® and Caché to not take advantage of large pages for shared memory on Windows, even though these products report that large pages are allocated. This can have detrimental effects on system performance.

What it the best method to call an object without ID but having RowID

Hi,

Does anyone have a simple code snippet to encode and upload a raw text to Azure Blob?

Running cache 5.0.21 64 bit on Windows server 2016 in virtual environment. Trying to understand why every single process disk read speed (simple sql data walks) caps around ~20MB/s, however 2 paralell such tasks on different data areas can reach 19MB/s each, four - 17MB/s each, that is 70MB/s total, etc. Also simple copy file to nul on that system reach ~400MB/s.

What can keep single query on idle system from reaching for example 200MB/s? Virtualization? Windows? Cache? Processors are below 1-3%

I need to list the source type and target type for all the DTL transformations in an Ensemble Production. I know I can get the source and target type for a single DTL transformation using :

set obj=##class(EXC.DTL.Lamont).%New()

write 'Source type: '_obj.GetSourceType()

write 'Target type: '_obj.GetTargetType()

Hello,
I have a list of files on disk.
Each record is the fully qualified UNC path and filename.
I would like to send these files to the end users default printer as a document.
I have attempted to build a html page using document.write statements and print using printWindow.print(); command.

I think there must be a better way to send a series of files to the windows print spooler.
I would welcome any and all input.

Hi all,

For custormer support reasons we would like to know if its possible to activate some kind of flag or see/redirect wich is the code (lines) being executed when some misterious problems appear.

Is there any way to view the stack of execution code on a deployed code environment? Is there any other equivalent way to track the execution stack for a certain period of time?

Best regards
