I get this on some queries in some namespaces. For instance, this query:

It works fine in HSBUS but in HSREG it throws the error.

Server closed communication device

Does anyone know what would cause this? Would it log something more useful somewhere?

I have a soap webservice extended from %SOAP.WebService class

Lets say i have web method and have return type of following classes (either one of them)

Class ReturnTypeA

The technology of load balancing between several servers with relatively low capacity has been a standard feature of Caché for quite a while. It is based on the distributed cache technology called ECP (Enterprise Cache Protocol). ECP provides a host of possibilities for horizontal scaling of an application, and yet keeping the project budget fairly low. Another apparent advantage of ECP network is the possibility to conceal its architecture in the depths of Caché configuration so that applications developed for the traditional (vertical) architecture can be fairly easily migrated to a horizontal ECP environment. The ease of this process is so mesmerizing, that you start wishing it was always this way. For instance, everybody is used to having a possibility to control Caché processes: the $Job system variable and associated classes/functions work magic in skilful hands. Stop, but now processes can end up being on different Caché servers…

This article is about how to gain as much transparency in controlling processes in ECP environment as in traditional (non ECP) one.

Hi,

I try to programmatically create a parameter for a dataCombo ZEN Component (which is in turn created on the server side at runtime).

Set tParm = ##class(%ZEN.Auxiliary.parameter).%New()
Set tParm.id = "pRegion#"_pExamContainerCount, tParm.name = "pRegion#"_pExamContainerCount

Since now i have been working from external connection but i want to work with the SQL utility of Management Portal

i dont know how to do with several instructions like in other editors like this example

update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  80 where CodigoNum = '100' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '101' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '102' and Empresa = 'CO'

it returns

Can Cache Monitor (^MONMGR) and System Monitor be configured to also send 'OK' messages? With the first bad email, you still wonder if things are still broken, when in-fact normalcy has been restored, some even within some seconds.

typical examples : -

------ - - - -- - - - -- - -- --- - -- -- -- - - - -- -- -- - --- - - - -- - - -- - - -- --- - - -- -- -- - - --- - - - - --- -- --- - - -- -- --- - - --- - --- -- - - -- -

Hi,

I have a process that is importing lots of data from an external file, but every now and then I come across a STORE error.

I know that the STORE error is occurring in the %Save method of the class but I know very little else and I think its something to do with a lage amounts of Related Objects.

Is there a method of finding out more information regarding this error i.e. which actual object was being saved etc etc.

Thanks

Jim

Running TuneTable accounts among other the parameter named Block Count. In documentation, we see that this is an approximate numbers of 2K-blocks in which SQL-maps are stored. Databases in recent Cache doesn't support 2K-physical blocks so SQL-blocks are not physical blocks as it seems. So two questions:

- what are these blocks?

- how knowledge about count of blocks can help in SQL optimization?

The DeepSee TroubleShooting Guide helps you track down and fix problems occurring in your DeepSee project. A common problem is finding less records than expected in a DeepSee Cube or a related Subject Area. The DeepSee TroubleShooting Guide suggests starting your investigation by checking the following:

Check cube for build restrictions

Check if maxFacts is used

Check if Build Errors are occurring

Question:

Where can I find the openssl command line tool for Windows?

Answer:

The openssl command line utility comes with Unix, but not with Windows. It is used for working with security certificates.

The main site is

https://www.openssl.org/

There are no binaries on this site but in the Community section there is a link for binaries which leads to:

Lets say i have a record "Person". If i want to access the "Name" property of that object which one of the following best option performance wise

1. Option 1

set record = ##class(Test.Person).%OpenId(1)

write record.Name

2. Option 2

write ##class(Test.Person).NameGetStored(1)

Recently I wrote about automatic removal of system methods from the codebase.

Today, I'm ready to present you a working solution (codename: SMR) for this task.

Index

This is a list of all the posts in the Data Platforms’ capacity planning and performance series in order. Also a general list of my other posts. I will update as new posts in the series are added.

You will notice that I wrote some posts before IRIS was released and refer to Caché. I will revisit the posts over time, but in the meantime, Generally, the advice for configuration is the same for Caché and IRIS. Some command names may have changed; the most obvious example is that anywhere you see the ^pButtons command, you can replace it with ^SystemPerformance.

While some posts are updated to preserve links, others will be marked as strikethrough to indicate that the post is legacy. Generally, I will say, "See: some other post" if it is appropriate.

Capacity Planning and Performance Series

Generally, posts build on previous ones, but you can also just dive into subjects that look interesting.
