Hi all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.

Hi,

The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.

It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.

Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

HI *,

So last night I was doing a deployment which had a query to select from a large dataset of joined tables, to iterate through and populate data in a new table.

This was done in a classmethod using embedded SQL and the %PARALLEL keyword.
On a testing environment with the same dataset, this worked perfectly a few days earlier.

Hi all,

I might be losing my mind or do not understand how ObjectScript does string comparisons, but the following does not look right to me.

Is it really possible that you can't compare non-numerical strings other than with an equals or not equals?

USER>w ("45" < "46")
1
USER>w ("45" > "46")
0
USER>w ("V45" < "V46")
0
USER>w ("V45" > "V46")
0
USER>w ("V45" <= "V46")
1
USER>w ("V45" >= "V46")
1

Hi all,

In the days when I was still using studio, the indentation character of choice was tab, due to misalignment of code when using non-monospaced fonts.

In VSCode when I create new class files, this defaults to 4 spaces. Where and how do I set the default indentation for ObjectScript class files?

Also, with python it should be spaces. So what is recommended when doing python script inside objectscript classes?

Thank you.

Hi *,

I want to dynamically generate the arguments of a method during compile time.

'For example, I want the following method

ClassMethod DoCleverStuf() As %Status [ CodeMode = objectgenerator ]
{
    do %code.WriteLine("    Set tSC = $$$OK")
    ...
}

to look like this in the .int code.

ClassMethod DoCleverStuf(pValue1 As %Integer, pValue2 As %String) As %Status [ CodeMode = objectgenerator ]
{
    // some generated code will be here
}

Is this possible? Or alternativel;y, can I generate a whole method at compile time?

Thanks.

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

VSCode: Formatter not found

Hi,

I am using VSCode together with IRIS 2021.1.
When using Shift+Alt+F to reformat a class file, it pops up with the below message. When I select install formatter, it routes me to the extensions page, where it shows the extensions as being installed. Any advice will be appreciated.

Hi,

We need a web-based SQL tool to connect to Ensemble/Cache, that will offer more functionality than what the Management Portal offers.
It needs to be web based, so that we can host it on a machine that has connectivity to the server via the superserver port. We (the devs and support) only have browser access to the environment via Remote Desktops, hence the requirement.

Has anyone gotten OmniDB to connect to Ensemble/Cache? If so, can you please advise on how to configure it?

Any other suggestions for such a tool are also welcome.

Hi,

I have the requirement to dump large result sets into files. I am currently using %SQL.Statement and the result set created by it.

The DisplayFormatted is used to write a CSV. The query I used to test does not contain any filters, it is just a select * from a table with 16 million rows.
The file created is 2GB in size. The issue I have is that it takes 8 hours to create this file.

Hi,

I am investigating creating builds from TravisCI, which will pull the source from github.
This will also involve a code review process, pull request, etc.

It will be done in Multiple phases. The first one will not involve automated testing using TravisCI yet. It will only involve travisCI pulling the latest code from github and creating a release for testing(A deployment file in a format that can be loaded by Ensemble0)

Hi,

The context of the rule set contains an ArrayOfDT(I've also tried Collection.ArrayOfDataTypes).

I need to access an element using its key in the rule set using the assign function. I've tried everything I can think of and searched the documentation, but can't find anything. It is probably very obvious.

Can you please help?

Hey folks,

I am new to IRIS and cloud platforms. I've done the InterSystems IRIS Experience on the learning site and read a lot of the online documentation. What I am unable to figure out is which type of package or option you will use on the cloud provider.

AWS for example, has AWS EC2, Elastic Beanstalk and some other products geared towards Docker containers.
Azure has Kubernetes and some other options.

Hi,

I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.

The signing is done using openssl.

This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.

The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.

The content is signed using RSA SHA256 with PSS padding.

Hi,

I have created a Business Service which uses the EnsLib.File.InboundAdapter. This service will call a business service which will create an acknowledgement file in a directory specified in the operation after loading the parsed file into some temporary tables.

In order to create the acknowledgement file, I need the original file name. In the OnProcessInput of the service, it receives a stream of file data, and I can't find a way to get hold of the file name.

Any advice will be appreciated, thank you.
