Question Marco Blom · Oct 21, 2016

I had a table which contained data and worked fine, without changes the code of the persistent classes I now get the following error:

II have tried to browse the data for a 'clue' but no result.

What is the explanation of the error message?

Thanks in advance!

Hi all, Basically i have 2 queries..

  1. Is there any simple way to fetch the data directly from the database (using the URL and credentials) from the csp file without creating a link table for that particular Table...?? If there is, could you please share the syntax of using them ..?

  2. Can we have an object return type from the below mentioned method to a javascript function.. ???

<script language="cache" method="methodName" arguments="argument1" returntype= "Not sure of the return type"> QUIT object </script>

Question Dmitry Maslennikov · Nov 24, 2016

Just curious how many companies use in their work Docker containers, I mean not only with InterSystems products. And if such companies exist, which of them uses docker and doesn't  use it for InterSystems products  by some reasons. What are the reasons? For companies which already uses InterSystems in containers, how do you use it? Development environment, testing or even in production ?

And if you don't use but thought about it, what are the reasons which stop you.

As for me, I've been using InterSystems Caché inside a Docker container in some different cases:

Does anyone know how to connect a Cache client to a GT.M database?  I recently installed Osehra VistA on my PC and it uses GT.M, but we're supposed to use Cache Studio to develop.  I tried adding a server to Cache (specifying 2222 as the port) and I get an "access denied" error.  Port  2222 is the correct port which I use for for VirtuaBox and I have no problem connecting to VistA.  I also tried going into the Management Portal to set up a local connection but this isn't working.  There are some sites that say the products 'nodem' or 'node.js' are necessary, but I'm not sure how these fit in

Hi,

I've managed to get a zen Report working where it outputs the contents to a pdf file - the pdf has a background image and it works perfectly. I now want to print that PDF from Caché.

I've tried to use the GenerateReport method - mode 12 — Generate a report in PDF format, and send it directly to a printer via the Caché Print Server e.g. sc=rep.GenerateReport("Printdoc.pdf",12)   (where "rep" is my zen report)

I've created the Caché print server in the management protal as per the documentation.

Good Morning,   All replies are appreciated.

We have a development instance of cache that was installed and the person that installed and set it up is no longer here.  We have no id's that we have the passwords for.  I have brought the database up in emergency mode and I can get access thru the terminal using my emergency id but I do not know how to add  a user/password thru the terminal.  Can someone enlighten me or point me to documentation that I haven't found yet.

Question Lutz Vogt · Nov 23, 2016

We tested REST Services  as described for Caché DocServer example and for requests using http protocol it works without problems. However when we use the https protocol for the same REST Service it is not available. Our infrastructure is as follows: Apache with openssl, which works on the other hand well for CSP with https. If we switch on the web gateway http trace facility we could see the request of CSP pages by https://... but again a request of a REST Service by https:// will not result in a entry in the tracer. We hope that this description of the problem is understandable.

Hi,

is there a way to copy namespace mappings from another namespace to a new namespace programmatically with a command?

When using management portal there is an option to choose an existing namespace to copy the mappings from, I'm basically looking for the equivalent from command line / COS.

Thanks

Martin

Caché Localization Manager

CLM  is a tool for localization/internationalization/adding multi-language support to a project based on InterSystems Caché.

Imagine that you have a ready project where all the content is in Russian, and you need to add an English localization to it. You wrap all your strings into resources, translate them into English and call the necessary resource for Russian or English when necessary. Nothing tricky, if you think about it. But what if there are lots of strings and there are mistakes in Russian (or English)? What if you need to localize in more than one language – say, ten? This is exactly the kind of project where you should use CLM. It will help you localize the entire content of your project into the necessary language and retain the possibility to correct entries.

i have this error

DrawTableError : <MAXSTRING> zDrawTable+349^%CSP.Util.TablePane.2

perhaps i have the possibility of Deleting all history queries, but i think better to check the table where last queries were stored and solve it by deleting wrong registries. anybody knows where is the table 'QueryHistory'.

Question Scott Beeson · Nov 18, 2016

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

SELECT TOP 10 SessionId, datediff(s,min(TimeCreated),max(TimeCreated)) as ResponseTime
FROM ens.messageheader
GROUP BY SessionId
ORDER BY ResponseTime DESC

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?

Question Paul Coviello · Nov 16, 2016

looking for what the timeout value is for the connection for shadowing. and if it is known the timeout for mirroring also.

I'm currently getting this error and when we go to mirroring it would be good to know also, this way we can go back to our network vendor and give them as much info as possible.

10/19/16-12:19:40:696 (d30b6) 2 [SHADOWING] SHADOW SERVER (PRODSHAD): <ZREAD>ReadNone+3^SHDWUTIL;ERROR #1071: TCP read timed out - remote server is not responding (repeated 16 times)

thanks

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.

Question Wendy Griffiths · Nov 17, 2016

Hi

I'm trying to use the ##class(%File).RemoveDirectory utility to delete a windows folder. The folder has nothing in it, but it is not getting deleted.

I've tried doing Set sc=##class(%File).RemoveDirectory(file,.return) and return is returning a -2.  I've also tried changing it to .Delete in case that worked, but I got the same. 

I've tried it on my local instance and on a customer site on an older version of Cache that doesn't have the return parameter, but it also fails to delete the folder on there too.

file is the full filename and path and the .Delete works fine when used on files.

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 : -

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

Question Steve Riddle · Nov 9, 2016

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

Question Mikko Laitamäki · Nov 15, 2016

Hi All,

I have SourceControl utility class as in sys namespace

Class %MW.Web Extends %CSP.Page {... }

Previously with Cache 2010.1 and below  there was no problem accessing it through

localhost:57772:/csp/myns/%MW.Web.cls

But now with newer version at least with  2016.2  I' ll get Forbidden message from it.

With Web Gateway HTTP Trace Facility 

GET /csp/ipanax2/%MW.Web.cls HTTP/1.1  

​-->  HTTP/1.1 403 Forbidden  

How can we make it accessible again? 
 

 Mikko
